What Rights Does a Buyer Have if a New Phuket Property Has Construction Defects?

Concise answer

A buyer of a newly completed Phuket condominium or villa may have rights against the developer, seller, contractor or another responsible party if the property is incomplete, poorly constructed, materially different from the agreed specifications or affected by hidden defects.

Depending on the contract and legal basis of the claim, the buyer may be able to:

• Require defects to be repaired
• Require incomplete work to be completed
• Set a reasonable deadline for corrective work
• Refuse to accept visibly defective work
• Record acceptance subject to a written defect list
• Withhold an unpaid amount where legally and contractually justified
• Arrange third-party repairs and seek recovery of the reasonable cost in qualifying construction-contract cases
• Claim compensation for proven losses
• Seek a price reduction or settlement
• Terminate the contract where the breach is sufficiently serious
• Use applicable consumer-protection procedures
• Commence court proceedings before the relevant limitation period expires

The buyer’s rights depend heavily on whether the transaction is legally characterised as:

1. A sale of completed property
2. An off-plan developer sale
3. A construction or hire-of-work contract
4. A combined land-sale and construction arrangement
5. A condominium-unit claim
6. A condominium common-property claim

Thai law does not provide one universal warranty period for every defect claim.

For a sale claim, Section 472 of the Civil and Commercial Code generally makes a seller responsible for a defect that reduces the property’s value or fitness for ordinary or contractually intended use. Section 474 generally requires an action based on that statutory defect liability to be brought within one year after the defect was discovered.

For a qualifying hire-of-work claim, Section 600 generally addresses defects appearing within one year after delivery or within five years for a structure on land other than a wooden building, unless the contract provides otherwise. Section 601 generally requires proceedings to be brought within one year after the defect appears.

These periods and legal classifications must be reviewed by a qualified Thai lawyer. A developer’s contractual warranty, a statutory defect claim and a general breach-of-contract claim are not necessarily the same thing.

The safest approach is to conduct an independent inspection before handover, document every defect, reserve the buyer’s rights in writing and obtain legal advice immediately if the developer does not respond.

Detailed explanation

1. A new property does not have to be perfect, but it must comply with the bargain

Minor cosmetic imperfections may be expected in a newly completed property.

That does not mean the buyer must accept:

• Water penetration
• Unsafe electrical work
• Failed waterproofing
• Structural movement
• Serious cracking
• Defective drainage
• Non-functioning systems
• Missing fixtures
• Substandard materials
• Unapproved design changes
• Incomplete common facilities
• Work materially inconsistent with the contract

The legal question is not simply whether the property contains an imperfection. It is whether the work complies with the contract, applicable standards and the property’s intended use.

2. The contract is the starting point

The buyer should examine:

• Sale and purchase agreement
• Construction agreement
• Reservation agreement
• Specifications
• Architectural drawings
• Approved plans
• Bill of quantities
• Material schedule
• Furniture schedule
• Variation orders
• Brochures and representations
• Handover conditions
• Defect-liability provisions
• Warranty terms
• Payment schedule
• Retention provisions
• Dispute-resolution clauses

A broadly worded sales brochure should not replace precise contractual specifications.

3. Different contracts create different rights

A buyer purchasing a finished condominium from a developer may primarily have a sale relationship.

A landowner employing a contractor to construct a villa may have a hire-of-work relationship.

An off-plan villa purchase may involve:

• Land-sale agreement
• Construction agreement
• Project-management agreement
• Furniture agreement
• Rental-management agreement
• Infrastructure obligations

Each contract may place responsibility on a different party.

4. The seller may be responsible for defects in property sold

Section 472 of the Thai Civil and Commercial Code generally provides that a seller is liable where a defect reduces:

• The value of the property
• Its fitness for ordinary use
• Its fitness for the purpose contemplated by the contract

This liability may apply whether or not the seller knew about the defect.

The facts, contract and legal characterisation must still be established.

5. Obvious and hidden defects are treated differently

An obvious defect is one that a reasonable inspection should reveal.

Examples may include:

• Broken tiles
• Missing doors
• Visible paint damage
• Misaligned cabinets
• Cracked windows
• Incomplete sanitary fittings
• Visible ceiling stains

A hidden or latent defect may not become apparent until later.

Examples may include:

• Failed concealed waterproofing
• Inadequate reinforcement
• Buried drainage failure
• Electrical faults inside walls
• Defective roof construction
• Foundation movement
• Concealed pipe leakage

Hidden defects require particularly careful expert investigation.

6. Accepting an obvious defect without reservation may weaken a claim

Section 473 contains important exceptions to statutory sale-defect liability.

The seller may have a defence where:

• The buyer knew about the defect when purchasing
• The buyer should have known about it through reasonable care
• The defect was apparent on delivery and the buyer accepted the property without reservation
• The property was acquired through public auction

A buyer should therefore avoid signing an unconditional statement that the property is complete and defect-free when visible defects remain.

7. Acceptance subject to defects should be recorded clearly

If the buyer accepts possession while defects remain, the handover record should state that acceptance is:

• Subject to the attached defect list
• Without waiver of contractual or statutory rights
• Without confirming that all work is complete
• Without confirming that concealed systems are defect-free
• Conditional upon rectification by stated deadlines

The developer and buyer should sign or acknowledge the defect list.

8. Taking keys does not necessarily resolve every defect claim

Receiving keys, moving furniture into the property or taking physical possession does not automatically prove that:

• Construction was properly completed
• Every defect was waived
• The property matches the specifications
• Common facilities were delivered
• Hidden defects do not exist
• All legal approvals were obtained

However, possession and signed handover documents may become important evidence. Their wording should be reviewed carefully.

9. Land Office transfer is not a construction-quality certificate

Registration of ownership confirms the legal transfer of the relevant registered property right.

It does not necessarily certify:

• Workmanship
• Waterproofing
• Structural performance
• Electrical safety
• Plumbing quality
• Compliance with specifications
• Completion of promised facilities
• Absence of hidden defects

Title due diligence and construction due diligence are separate exercises.

10. Building approval does not guarantee defect-free construction

A building permit confirms regulatory permission to construct according to approved plans and applicable requirements.

It is not a commercial warranty from the government.

Similarly, a completion, use or inspection document does not necessarily establish that every part of the property:

• Meets the buyer’s contract
• Uses the promised materials
• Has no workmanship defects
• Will remain watertight
• Has been tested under normal occupation
• Has no concealed problems

Administrative approval and private defect liability should be assessed separately.

11. A handover inspection should occur before final acceptance

The buyer should arrange an independent inspection before:

• Final payment
• Signing the handover certificate
• Accepting the keys unconditionally
• Authorising release of retention
• Registering transfer where the contract permits inspection first
• Starting rental operations

The inspection should allow enough time for testing rather than merely viewing the property.

12. The inspector should be independent

A developer’s site engineer represents the developer’s interests.

The buyer may need an independent:

• Architect
• Civil or structural engineer
• Mechanical and electrical engineer
• Building surveyor
• Quantity surveyor
• Swimming-pool specialist
• Waterproofing specialist

The appropriate expert depends on the property and suspected defect.

13. A standard snagging inspection has limits

A visual inspection may identify:

• Surface cracking
• Poor finishes
• Missing items
• Damaged fixtures
• Uneven floors
• Window and door problems
• Visible leaks
• Drainage problems
• Non-functioning equipment

It may not identify:

• Incorrect reinforcement
• Inadequate foundations
• Concealed pipework
• Buried services
• Hidden waterproofing failure
• Soil instability
• Undersized electrical systems

Serious warning signs may justify specialist testing.

14. Phuket’s climate creates particular construction risks

Phuket properties may experience:

• Heavy seasonal rain
• Wind-driven water
• High humidity
• Salt-laden coastal air
• Corrosion
• Mould
• Strong sunlight
• Ground saturation
• Slope drainage
• Termite activity
• Pool and retaining-wall pressure

Materials and construction details should be appropriate for the site rather than merely attractive at handover.

15. Water intrusion should not be dismissed as cosmetic

Water entering through roofs, walls, windows, balconies or below-grade areas may cause:

• Mould
• Corrosion
• Electrical risk
• Damaged finishes
• Concrete deterioration
• Uninhabitable rooms
• Rental interruption
• Repeated repair costs

Painting over a stain does not establish that the underlying failure has been corrected.

16. Cracks require proper classification

Not every crack indicates structural failure.

Cracks may arise from:

• Drying shrinkage
• Plaster movement
• Temperature changes
• Differential settlement
• Structural movement
• Inadequate reinforcement
• Poor joints
• Water penetration

A developer should not label a crack “normal settlement” without supporting technical assessment where the pattern, width or progression is concerning.

17. Retaining walls and hillside construction need special attention

For sloping Phuket sites, defects may affect:

• Retaining walls
• Slope stability
• Cut-and-fill areas
• Surface drainage
• Subsoil drainage
• Foundations
• Boundary structures
• Neighbouring land

Movement, bulging, persistent water discharge or significant cracking should be assessed urgently by a qualified structural or geotechnical engineer.

18. Swimming pools require more than a visual check

Pool defects may involve:

• Shell cracking
• Leakage
• Waterproofing
• Pipe failure
• Pump sizing
• Filtration
• Electrical bonding
• Drainage
• Overflow systems
• Plant-room ventilation
• Defective tiles

Water loss should be distinguished from ordinary evaporation through controlled testing.

19. Mechanical and electrical systems should be tested

The inspection may include:

• Main electrical board
• Circuit protection
• Earthing
• Residual-current protection
• Socket operation
• Air-conditioning
• Hot-water systems
• Water pressure
• Pumps
• Wastewater systems
• Drainage falls
• Ventilation
• Fire-safety equipment
• Backup power where promised

A system that switches on briefly may not perform adequately under normal load.

20. The buyer should compare the property with the contractual specifications

Defects are not limited to broken items.

A property may also be non-compliant because the developer supplied:

• Different stone
• Lower-grade windows
• Smaller equipment
• Different sanitaryware
• Fewer appliances
• Inferior air-conditioning
• Reduced landscaping
• Different doors
• Lower-quality cabinetry
• Changed pool equipment

The buyer should compare model numbers, brands, dimensions and performance—not only appearance.

21. Substitution clauses should not be unlimited

A contract may permit substitutions where a specified product is unavailable.

That should not automatically allow the developer to provide materially inferior items.

A reasonable substitution mechanism should address:

• Equivalent quality
• Equivalent performance
• Buyer notification
• Buyer approval for material changes
• Price adjustment
• Evidence of unavailability

A broad substitution clause should be reviewed under Thai contract and consumer law.

22. Incomplete work is not always the same as defective work

Incomplete work may include:

• Missing fixtures
• Unfinished landscaping
• Uninstalled appliances
• Uncommissioned systems
• Incomplete roads
• Missing utilities
• Unfinished common facilities

Defective work exists but does not perform or comply properly.

The distinction may affect completion, payment and available remedies.

23. The buyer may be able to demand correction

Under a construction or hire-of-work arrangement, the buyer may be able to notify the contractor of defective or non-compliant work and require correction within a reasonable period.

The notice should identify:

• Exact location
• Nature of the defect
• Supporting photographs
• Relevant specification
• Required corrective outcome
• Inspection access
• Deadline
• Consequences of non-compliance
• Reservation of rights

The buyer should retain evidence that the notice was received.

24. Third-party repair may sometimes be recoverable

Under the hire-of-work provisions, an employer may in appropriate circumstances require the contractor to rectify defective work and, if the contractor fails to do so within the required period, arrange correction by another party at the contractor’s expense.

This should not be attempted casually.

Before appointing a replacement contractor, the buyer should obtain legal advice concerning:

• Required notice
• Reasonable rectification period
• Evidence of default
• Scope of work
• Competitive repair quotations
• Preservation of evidence
• Mitigation of loss
• Access rights
• Contract termination
• Recovery prospects

Premature intervention may create disputes about causation and cost.

25. Emergency repairs may be necessary

If a defect threatens people or property, the buyer may need to act immediately.

Examples include:

• Dangerous electrical fault
• Major water leak
• Unstable wall
• Falling material
• Sewage escape
• Fire-safety failure
• Severe roof damage

Where possible, the buyer should:

1. Photograph and record the condition.
2. Notify the responsible party immediately.
3. Obtain an expert’s emergency recommendation.
4. Limit work to what is reasonably necessary.
5. Preserve removed materials where relevant.
6. Keep invoices and payment records.
7. Avoid destroying evidence unnecessarily.

26. The buyer has a duty to limit avoidable loss

A buyer should not knowingly allow a manageable defect to cause greater damage merely to increase a claim.

For example, a buyer who discovers an active pipe leak should take reasonable measures to prevent continuing water damage.

Mitigation does not mean accepting responsibility for the original defect. It means taking reasonable steps to prevent avoidable escalation.

27. Payment withholding must be handled carefully

A buyer may wish to withhold the final instalment or retention until defects are repaired.

Whether that is permitted depends on:

• Contract wording
• Payment milestones
• Severity of defects
• Whether completion has legally occurred
• Applicable hire-of-work provisions
• Whether security has been offered
• Proportionality of the withheld amount

Wrongful non-payment may place the buyer in breach. The buyer should obtain legal advice before withholding a substantial sum.

28. Retention is valuable protection

A well-drafted construction contract may allow the buyer to retain part of the price until:

• Practical completion
• Defects are corrected
• Systems are commissioned
• As-built documents are delivered
• Warranties are assigned
• A later defects inspection is completed

Without retention, the buyer may have less practical leverage after the contractor has received the full price.

29. The developer’s warranty is important but not necessarily the only right

A contractual warranty may state:

• Covered defects
• Warranty period
• Structural period
• Equipment period
• Exclusions
• Notice procedure
• Repair timetable
• Access requirements
• Approved contractors
• Transferability to a later owner

The expiry of a contractual warranty does not automatically answer whether another statutory or contractual claim exists.

Conversely, a long advertised warranty is only useful if its terms are enforceable and the responsible company remains solvent.

30. Warranty periods should not be confused with court deadlines

Several different periods may operate simultaneously:

Reporting a defect does not necessarily stop a court limitation period.

Repair negotiations may also fail to suspend or extend the deadline. A Thai lawyer should confirm the exact date by which proceedings must be commenced.

31. Sale-defect claims can have a short limitation period

Section 474 generally prevents an action based on statutory sale-defect liability from being brought later than one year after discovery of the defect.

The date of discovery may therefore become disputed.

Relevant evidence may include:

• First photograph
• Email to developer
• Inspection report
• Contractor visit
• Tenant complaint
• Insurance notification
• Repair quotation
• Expert diagnosis

A buyer should not allow repeated informal promises to consume the available time.

32. Construction-contract rules use a different framework

Section 600 generally provides that a contractor is liable for defects appearing within one year after delivery of the work.

For a structure on land other than a wooden building, the statutory period is generally five years.

The contract may provide otherwise, and liability may differ where the contractor concealed the defect.

Section 601 generally requires an action to be commenced within one year after the defect appeared.

The interaction between Sections 600 and 601 is technical. A five-year appearance period should not be understood as permission to wait five years after discovering a defect.

33. Legal classification can determine the deadline

A claim may potentially be framed as:

• Statutory sale-defect liability
• Breach of an express warranty
• Breach of construction contract
• Failure to deliver contractual specifications
• Misrepresentation
• Deliberate concealment
• Consumer claim
• Negligent professional service
• Claim concerning common property

Different causes of action can carry different requirements and limitation periods.

A buyer should not select a deadline from an online summary without having the documents and facts legally classified.

34. Repair attempts should be documented

Every developer or contractor visit should record:

• Date
• Persons attending
• Work performed
• Materials used
• Area opened
• Photographs before and after
• Whether the repair was temporary
• Whether the buyer accepted the outcome
• Whether the defect returned

Repeated unsuccessful repairs may help establish that the underlying cause was not corrected.

35. A repair should address the cause, not merely the symptom

Examples of superficial repair include:

• Painting over water staining
• Filling a moving crack without investigation
• Replacing damaged flooring without stopping moisture
• Applying sealant where flashing is defective
• Pumping out water without correcting drainage
• Re-grouting a leaking pool without leak testing

The buyer should request a method statement for significant work.

36. The developer should not control the only technical evidence

For serious defects, the buyer should obtain an independent report addressing:

• Observed condition
• Probable cause
• Further testing required
• Safety implications
• Contractual non-compliance
• Recommended correction
• Estimated cost
• Urgency
• Consequential damage
• Whether occupation should continue

The expert should remain independent and avoid conclusions outside their professional competence.

37. Destructive testing requires planning

Some defects cannot be diagnosed without opening:

• Walls
• Ceilings
• Floors
• Roof assemblies
• Pool finishes
• Drainage systems

Before destructive testing, the parties should agree where possible on:

• Scope
• Attendance
• Photographic record
• Samples
• Restoration
• Cost
• Testing laboratory
• Chain of evidence

Unilateral destructive work may generate arguments about who caused the damage.

38. Buyer alterations may complicate liability

A developer may blame the defect on:

• Renovation
• Furniture installation
• New air-conditioning
• Pool modification
• Added roof structures
• Landscaping
• Drilling
• Changed drainage
• Tenant misuse
• Inadequate maintenance

The buyer should preserve evidence of the original condition and document all later work.

If alterations are planned, existing defects should be inspected and notified first.

39. Maintenance exclusions must be reasonable and relevant

A warranty may exclude damage caused by poor maintenance.

That does not mean every defect can be described as maintenance-related.

The developer should explain:

• Required maintenance
• Required frequency
• Product or system involved
• Buyer’s alleged failure
• How that failure caused the defect
• Supporting technical evidence

The buyer should keep maintenance contracts, invoices and service records.

40. Condominium unit defects and common-property defects are different

An individual unit owner may encounter a defect originating in:

• Their private unit
• The unit above
• An external wall
• The roof
• Common pipework
• Common electrical systems
• The building structure
• Common drainage
• Developer-retained property

Responsibility cannot be determined solely by where the damage appears.

A ceiling leak inside one unit may originate from common property or another privately owned unit.

41. The condominium juristic person may need to act

Once a condominium juristic person is operating, claims affecting common property may require involvement from:

• Juristic-person manager
• Management committee
• Co-owners’ meeting
• Building insurer
• Developer
• Main contractor
• Relevant professional

The buyer should obtain:

• Incident reports
• Committee minutes
• Maintenance records
• Original construction documents
• Contractor correspondence
• Insurance information
• Other owners’ reports

A collective defect may be more effectively investigated on a building-wide basis.

42. An individual owner may still have a separate loss

Even where the underlying defect affects common property, an individual owner may suffer:

• Interior damage
• Loss of rental income
• Temporary accommodation costs
• Damaged furniture
• Mould remediation
• Loss of use
• Professional fees

The owner should obtain advice on whether those losses should be claimed from the developer, juristic person, insurer or another party.

43. Villa projects may divide responsibility among several companies

A villa development may involve:

• Landowning company
• Developer
• Main contractor
• Project manager
• Architect
• Engineer
• Pool contractor
• Landscape contractor
• Management company
• Material suppliers

The company that marketed the project may not be the company legally responsible under each contract.

The buyer should identify the correct counterparty before issuing a formal notice.

44. Professional-design defects may require separate analysis

A defect may result from:

• Incorrect design
• Poor construction
• Unsuitable materials
• Failure to supervise
• Unapproved change
• Failure to follow drawings
• Combination of several causes

The contractor, developer, architect, engineer or project manager may have different responsibilities.

A buyer should not assume that every defect is automatically the main contractor’s sole responsibility.

45. Contract termination is usually a serious remedy

Minor defects ordinarily do not justify treating the entire transaction as terminated.

Termination may become relevant where:

• The property is unsafe
• Essential work cannot be corrected
• Defects are fundamental
• The property is materially different from what was purchased
• The developer refuses to perform
• Completion has not legally occurred
• A contractual termination condition is satisfied

Wrongful termination can expose the buyer to counterclaims. Independent legal advice is essential.

46. Damages require evidence

A buyer claiming compensation should document:

• Repair cost
• Expert fees
• Temporary accommodation
• Lost rent
• Damaged contents
• Cleaning and remediation
• Additional management cost
• Finance cost
• Diminution in value
• Other foreseeable loss

Not every claimed expense will necessarily be recoverable.

The buyer must usually establish breach, causation, reasonable amount and mitigation.

47. Loss of rental income is not automatically recoverable

A buyer may claim that defects prevented occupation or rental.

Evidence may include:

• Existing reservation
• Executed tenancy
• Rental-management records
• Comparable bookings
• Closure period
• Repair schedule
• Cancellation records
• Refunds
• Historical performance

Projected income based only on optimistic marketing may be difficult to prove.

48. Insurance may respond to some damage but not defective work itself

Property insurance may cover resulting damage from a qualifying insured event while excluding:

• Poor workmanship
• Defective design
• Inherent defects
• Wear and tear
• Gradual deterioration
• Known conditions

For example, a policy might respond to certain water damage without paying to replace the defective waterproofing that caused it.

The buyer should notify the insurer promptly without admitting liability.

49. Developer insolvency creates practical risk

A buyer may have a valid legal claim but limited recovery if the developer or contractor:

• Has stopped trading
• Has no meaningful assets
• Has transferred assets
• Has entered rehabilitation
• Is insolvent
• Exists only as a project company
• Has allowed insurance or guarantees to expire

Financial due diligence and contractual security are therefore important before purchase.

50. Consumer-protection law may also be relevant

A private buyer purchasing from a professional developer may qualify as a consumer, depending on the facts.

Potentially relevant legislation includes:

• Consumer Protection Act
• Consumer Case Procedure Act
• Unfair Contract Terms Act
• Condominium Act
• Land-development legislation where applicable
• Civil and Commercial Code

Consumer remedies do not remove the need to preserve evidence or comply with limitation periods.

51. Condominium sale contracts may be subject to prescribed requirements

Section 6/2 of the Condominium Act requires a condominium business operator’s sale agreement to comply with the prescribed contract form.

A contractual provision that differs from the prescribed form and disadvantages the buyer may be unenforceable to that extent.

The current prescribed form, contract version and applicability should be checked by a Thai condominium lawyer.

52. A complaint is not the same as a court claim

A buyer may complain to:

• Developer
• Contractor
• Condominium juristic person
• Office of the Consumer Protection Board
• Relevant local authority
• Professional council
• Insurer

A complaint may encourage investigation or settlement.

It does not necessarily stop a statutory limitation period or replace the commencement of legal proceedings.

53. Regulatory and civil remedies have different purposes

A local authority may investigate:

• Unauthorised construction
• Unsafe building conditions
• Building-control violations
• Work inconsistent with approved plans

That investigation does not automatically compensate the buyer.

Conversely, a private settlement does not necessarily legalise unauthorised work.

Both regulatory and contractual issues may need to be addressed.

54. Settlement terms should be precise

A repair settlement should identify:

• Defects covered
• Repair method
• Responsible contractor
• Materials
• Start date
• Completion date
• Access
• Temporary accommodation
• Inspection
• Testing
• Consequences of failure
• Warranty for corrective work
• Payment or retention
• Whether any claims are released

The buyer should avoid a broad release before the corrective work has been completed and tested.

55. The corrective-work warranty should restart where appropriate

If a major defective system is replaced, the buyer should seek a fresh warranty for the replacement work.

Otherwise, the developer may argue that the original warranty expired shortly after the repair.

The written settlement should state when the corrective-work warranty begins and what it covers.

56. Resale disclosure should be handled carefully

An owner selling a property with known defects should obtain advice about disclosure.

Concealing:

• Active leakage
• Structural movement
• Repeated failed repairs
• Unauthorised modifications
• Common-property disputes
• Major pending assessments

may create liability to the next buyer.

Repair records and expert reports should be retained.

57. The best protection begins before signing

Before entering an off-plan or construction contract, the buyer should negotiate:

• Detailed specifications
• Approved drawing hierarchy
• Material approval
• Inspection access
• Independent testing
• Clear completion standard
• Defect categories
• Rectification deadlines
• Retention
• Performance security
• Warranty periods
• Assignable manufacturer warranties
• As-built documentation
• Dispute procedure
• Termination rights
• Developer responsibility for subcontractors

A vague contract makes later enforcement more difficult.

58. The buyer should act promptly

Once a serious defect appears, the buyer should:

1. Prevent immediate danger.
2. Photograph and video the condition.
3. Preserve relevant materials.
4. Notify the responsible parties in writing.
5. Obtain an independent inspection.
6. Review the contracts and warranty.
7. Establish the first-discovery date.
8. Obtain repair estimates.
9. Avoid signing waivers.
10. Consult a Thai property-dispute lawyer.
11. Calculate all possible limitation deadlines.
12. Commence formal proceedings in time if resolution fails.

Waiting for the developer to “come back next month” can be dangerous where a short legal deadline is running.

52. Commence formal proceedings before the applicable deadline expires.

Greg’s professional perspective

Construction defects are much easier to manage when the buyer still controls the final payment and has not signed an unconditional handover certificate.

For a new Phuket property, I want the buyer to have five things before accepting completion:

1. A detailed contract and specification
2. An independent inspection
3. A written defect list
4. A defined rectification timetable
5. Meaningful financial leverage until the work is completed

The phrase “it is covered by the warranty” is not enough. The warranty must identify who is responsible, what is covered, how quickly the defect must be investigated and what happens if the developer does not repair it.

Phuket’s first substantial rainy season is often an important test. A property that appears perfect during dry weather may reveal problems with roofs, windows, balconies, drainage, retaining walls or waterproofing once exposed to sustained rain.

Buyers should also understand that the legal deadline may be shorter than the period displayed in a developer’s marketing material. A five-year reference associated with certain structural hire-of-work claims does not necessarily mean the buyer can wait five years after discovering a defect.

The practical sequence is straightforward: inspect, document, notify, preserve evidence, set a deadline and obtain legal advice before the claim becomes time-barred.

Phuket Realtor helps buyers coordinate independent property, legal and technical checks before final acceptance. That is how buyers Invest with Confidence.

This entry provides general educational information and does not constitute legal, engineering, architectural, construction, insurance, property, tax, investment or financial advice.

Construction-defect rights depend on the contracts, transaction structure, nature of the defect, date of discovery, handover documents, applicable statutory provisions, responsible parties and evidence. Statutory and contractual deadlines may be short and may continue running during negotiations or repair attempts.

Buyers should obtain case-specific advice from a qualified independent Thai lawyer and an appropriately qualified technical professional before withholding payment, refusing handover, terminating a contract, appointing a replacement contractor or commencing proceedings.
