What Happens if a Phuket Off-Plan Development Is Completed Late?

Concise answer

If a Phuket off-plan property is completed late, the buyer’s rights depend primarily on:

• The sale and purchase agreement
• The contractual completion date
• Any permitted grace period
• The definition of completion
• The cause of the delay
• Any force-majeure clause
• Whether the buyer has complied with payment obligations
• Whether the developer is still capable of completing the project
• Thai contract and consumer-protection law

A delay does not automatically cancel the contract or entitle the buyer to an immediate refund.

Depending on the circumstances, the buyer may be able to:

• Require updated construction information
• Give formal notice demanding completion
• Claim contractual delay compensation
• Suspend a payment where legally and contractually justified
• Negotiate a revised completion schedule
• Obtain additional security or concessions
• Terminate the contract after a contractual longstop date
• Recover amounts already paid
• Claim interest or damages
• File a consumer complaint
• Pursue mediation, arbitration or court proceedings

The buyer should not stop paying instalments, accept an extension, sign a waiver or terminate the agreement without independent Thai legal advice. An incorrect response could place the buyer—not the developer—in contractual default.

The strongest protection is negotiated before signing: a definite completion date, limited grace period, narrow force-majeure clause, measurable construction milestones, meaningful delay compensation, a final longstop date and a clear refund mechanism.

Detailed explanation

1. Off-plan buyers purchase a contractual promise

When buying off-plan, the buyer is not initially acquiring a completed condominium or villa.

The buyer is generally contracting for the developer to:

• Construct the property
• Follow approved plans and specifications
• Complete agreed infrastructure
• Obtain necessary approvals
• Deliver possession
• Register ownership or leasehold rights
• Transfer the property by an agreed date

Until completion and registration, the buyer principally holds contractual rights against the developer.

This distinction matters because payment does not itself give the buyer registered ownership.

2. “Completion” can have several meanings

A project may be described as complete even though the property is not legally or practically ready.

Possible completion stages include:

1. Structural completion
2. Practical completion
3. Unit construction completion
4. Common-area completion
5. Infrastructure completion
6. Government inspection
7. Building-use approval
8. Condominium registration
9. Condominium unit-title issuance
10. Handover
11. Defect rectification
12. Land Office transfer

A buyer should determine which event the contract uses to measure the developer’s deadline.

A condominium building may look complete but still be unable to transfer because condominium registration, unit titles, foreign-quota documentation or mortgage releases are not ready.

A villa may be physically habitable while roads, utilities, drainage, permits, title subdivision or lease registration remain incomplete.

3. The construction date and transfer date may be different

Contracts sometimes contain separate dates for:

• Estimated construction completion
• Practical completion
• Handover
• Registration
• Ownership transfer
• Lease registration
• Common-area completion

A developer may finish the unit but still delay legal transfer.

The contract should therefore be reviewed for every relevant date—not just the date shown in the sales brochure.

4. An estimated date may not be a binding deadline

Marketing materials often use expressions such as:

• Expected completion
• Target completion
• Anticipated handover
• Scheduled for completion
• Approximately 24 months
• Construction expected by
• Subject to change

These phrases may provide less protection than a contractual obligation stating that the developer shall complete and transfer the property no later than a specified date.

A buyer should distinguish between:

The signed agreement normally carries more weight than informal sales representations, although misleading advertising may still be relevant.

5. The starting date must also be clear

A promise to complete “within 24 months” is incomplete unless the contract identifies when the 24 months begin.

Possible starting events include:

• Reservation date
• Contract-signing date
• First payment
• Building-permit issuance
• Environmental approval
• Commencement of construction
• Foundation completion
• Developer’s written notice
• Financing approval
• Land subdivision
• Condominium registration application

If the starting event is controlled entirely by the developer, the completion obligation may become uncertain.

A buyer should prefer an objective starting date and an absolute final deadline.

6. Grace periods can substantially extend delivery

A contract may grant the developer an additional grace period of:

• 90 days
• 120 days
• 180 days
• 365 days
• Another stated period

For example:

The exact calculation should be confirmed because contracts may use calendar days, business days or months.

A grace period is not necessarily improper, but it should be:

• Clearly stated
• Commercially reasonable
• Included in the buyer’s planning
• Separate from force majeure
• Reflected in the payment schedule
• Followed by meaningful buyer remedies

7. A longstop date is one of the buyer’s strongest protections

A longstop date is the final date by which completion or transfer must occur before the buyer may exercise specified remedies.

A good longstop clause should explain:

• The exact date
• The event that must occur
• Whether force majeure may extend it
• Maximum permitted extension
• Notice procedure
• Buyer’s right to terminate
• Refund deadline
• Interest on refunded money
• Treatment of bank charges
• Treatment of foreign-exchange losses
• Whether damages remain available

Without a longstop date, the buyer may face repeated extensions without a clear exit.

8. Delay does not automatically amount to abandonment

Construction projects can be delayed by ordinary commercial or technical problems.

Examples include:

• Labour shortages
• Material delays
• Contractor disputes
• Design revisions
• Utility connections
• Government inspections
• Title subdivision
• Condominium registration
• Financing difficulties
• Supply-chain disruption
• Weather
• Infrastructure construction
• Approval delays

Some delays may be temporary and capable of correction. Others may signal that the developer lacks the money, land rights, permits or ability to complete.

The buyer should investigate the cause rather than relying solely on a revised completion promise.

9. Force majeure should be interpreted carefully

A force-majeure clause may excuse or extend performance when an event outside the developer’s reasonable control prevents completion.

Possible events may include:

• Natural disaster
• War
• Government prohibition
• Epidemic-related legal restriction
• Unavoidable civil disturbance
• Exceptional events beyond reasonable control

The clause should not automatically treat normal development risks as force majeure.

Buyers should question language that includes:

• Lack of developer financing
• Slow sales
• Contractor insolvency
• Ordinary seasonal rain
• Predictable labour shortages
• Material-price increases
• Developer-controlled permit applications
• Internal corporate disputes
• Design changes requested by the developer
• Any event the developer considers inconvenient

A force-majeure event should have a demonstrable causal connection to the delay.

10. Force majeure should not create an unlimited extension

Even a legitimate force-majeure event should not necessarily allow indefinite delay.

The contract should address:

• Prompt written notice
• Evidence of the event
• Date the event began
• How it prevented performance
• Developer’s mitigation obligations
• Maximum extension
• Updated construction programme
• Buyer’s termination right after prolonged delay

The buyer should avoid clauses that let the developer extend completion unilaterally without a final limit.

11. Developer notices should be examined, not merely accepted

When announcing a delay, the developer should ideally provide:

• Current construction percentage
• Work completed
• Work outstanding
• Updated programme
• Revised practical-completion date
• Revised transfer date
• Explanation of the cause
• Permit and approval status
• Contractor status
• Financing status
• Photographic evidence
• Independent engineer’s report, where appropriate
• Proposed buyer remedies

A generic email saying that completion has been “slightly postponed” is not enough for a material delay.

12. Construction percentage can be misleading

A developer may report that a project is 80% or 90% complete.

The percentage may refer only to:

• Structural work
• Construction cost incurred
• Individual unit work
• The developer’s internal schedule
• Visible construction

The remaining work may include time-consuming matters such as:

• Mechanical and electrical systems
• Fire-safety systems
• Roads
• Drainage
• Water supply
• Electricity
• Elevators
• Landscaping
• Common facilities
• Testing and commissioning
• Government approval
• Title issuance
• Mortgage release

The buyer should ask how the percentage was calculated and whether it has been independently certified.

13. A late condominium and a late villa present different risks

The buyer’s remedies must be tailored to the actual property and ownership structure.

14. The buyer should check whether the developer is still financially viable

Warning signs may include:

• Construction has stopped
• Few workers remain on site
• Contractors have left
• Suppliers complain of non-payment
• Developer repeatedly changes contractors
• Land or project is newly mortgaged
• Developer requests accelerated payments
• Developer offers unusually large discounts
• Management stops providing written updates
• Company accounts are overdue
• Directors or shareholders change unexpectedly
• Court proceedings or creditor claims appear
• Other projects are also delayed
• Refunds are not being paid

A delayed project may still be recoverable. A financially distressed project presents a more serious risk because an unsecured buyer may have to compete with banks, employees, contractors, tax authorities and other creditors.

15. Updated company and title searches may be necessary

The buyer’s lawyer may examine:

• Developer company registration
• Current directors
• Signing authority
• Shareholders
• Registered capital
• Financial statements
• Changes in corporate status
• Litigation
• Insolvency proceedings
• Project-land title
• Mortgages
• Servitudes
• Court orders
• Attachments
• Restrictions
• Development licences

The purpose is to determine whether the delay is operational or connected to a deeper legal or financial problem.

16. The buyer should continue documenting everything

The buyer should preserve:

• Reservation agreement
• Sale and purchase agreement
• Amendments
• Payment schedule
• Payment receipts
• Bank-transfer records
• FET or foreign-exchange evidence
• Marketing materials
• Floorplans
• Specifications
• Completion promises
• Construction updates
• Photographs
• Emails
• Messaging records
• Meeting notes
• Developer notices
• Inspection reports
• Legal correspondence
• Evidence of additional expenses

These documents may be important in negotiations, consumer complaints, mediation, arbitration or litigation.

17. The buyer should check whether the buyer is already in default

Before claiming against the developer, the buyer should confirm that the buyer has:

• Signed required documents
• Paid instalments when properly due
• Provided identity documents
• Supplied foreign-funds evidence
• Responded to lawful notices
• Attended inspections
• Avoided unauthorized alterations
• Complied with financing obligations
• Followed contractual notice procedures

A developer may rely on buyer default as a defence or attempt to terminate the agreement and retain payments.

18. Buyers should not stop paying automatically

A delayed project does not always give the buyer an immediate right to withhold an instalment.

Stopping payment without a valid basis may allow the developer to allege:

• Buyer default
• Contract termination
• Deposit forfeiture
• Late-payment interest
• Loss of the unit
• Damages

Before withholding payment, the buyer’s lawyer should review:

• Whether payment is date-based or milestone-based
• Whether the milestone was actually achieved
• Whether certification is required
• Whether the developer is in material breach
• Whether Thai law permits withholding
• Whether formal notice is required
• Whether funds could be placed in escrow or held pending resolution

The safer response is often a formally documented position rather than a unilateral refusal to pay.

19. Milestone payments provide better protection than date-based payments

A payment schedule based solely on dates may require the buyer to continue paying even when construction falls behind.

A stronger schedule connects payments to independently verifiable stages.

Important milestones may include:

• Foundation completed
• Structure completed
• Roof completed
• Mechanical and electrical installation
• Unit practical completion
• Common infrastructure operational
• Required approvals obtained
• Title ready
• Mortgage release ready
• Transfer appointment confirmed

20. Delay compensation should be meaningful

Contracts may provide compensation calculated as:

• Fixed amount per day
• Percentage of purchase price
• Percentage of amounts paid
• Interest on buyer payments
• Actual documented loss
• Rental-value equivalent
• Another agreed formula

The buyer should examine:

• When compensation begins
• Whether the grace period must expire first
• Maximum compensation
• Whether it is automatically credited
• Whether the buyer must submit a claim
• Whether accepting compensation waives termination
• Whether compensation continues until handover or legal transfer
• Whether the developer can substitute vouchers or services

A nominal penalty may provide little incentive for timely completion.

21. Contractual penalties may be reviewed by a court

Thai contract law recognises agreed penalties, but a court may reduce a penalty considered disproportionately high.

The Thai Civil and Commercial Code also addresses deposits, non-performance, damages and stipulated penalties. Sections commonly relevant include Sections 203–223 and 377–383. An unofficial English reference text states that non-performing debtors may face performance and damages claims and that agreed penalties can apply to late or improper performance, subject to judicial adjustment. Thai Civil and Commercial Code—Book II

The buyer should not assume that every contractual penalty will be enforced exactly as written.

22. The buyer may need to issue a formal notice to perform

Under general Thai contractual principles, termination may require the non-defaulting party to give the defaulting party a reasonable additional period to perform.

The notice should normally be prepared or reviewed by a Thai lawyer and may state:

• Contract and property
• Relevant completion obligation
• Original deadline
• Grace period
• Nature of default
• Required corrective action
• Additional period to perform
• Documents required
• Reservation of rights
• Consequences of continued default

Section 387 of the Civil and Commercial Code provides a general mechanism under which a party may set a reasonable period for performance and terminate if performance is still not made. Section 388 addresses circumstances where performance by a specified date is essential. Thai Civil and Commercial Code—termination provisions

Whether notice is required depends on the contract and facts.

23. The buyer should not rely on informal cancellation

A telephone call, WhatsApp message or verbal statement may not validly terminate the agreement.

The contract may require notice by:

• Registered post
• Courier
• Personal delivery
• Specified email address
• Lawyer’s letter
• Notice to the company’s registered office
• Notice within a specific period

The buyer should comply precisely with the contractual notice clause and preserve proof of delivery.

24. Termination and refund are not always automatic

A buyer may have termination rights when:

• Contractual longstop date expires
• Developer fails to perform after proper notice
• Completion becomes impossible
• Developer abandons the project
• Material contractual representations are false
• Developer cannot deliver the agreed ownership
• Project lacks essential approvals
• Another express termination event occurs

However, a buyer who terminates prematurely may be treated as the defaulting party.

The termination decision should therefore be based on:

• Contract wording
• Thai law
• Evidence
• Proper notice
• Materiality of breach
• Developer’s ability to cure
• Buyer’s own compliance

25. A refund claim may include more than the original deposit

Depending on the contract and law, a buyer may seek:

• Reservation fee
• Contract deposit
• Construction instalments
• Foreign-freehold premium
• Upgrade payments
• Interest
• Contractual compensation
• Bank charges
• Legal expenses
• Inspection expenses
• Temporary accommodation costs
• Lost rental income
• Exchange-rate losses
• Other foreseeable and provable damages

Not every claimed loss will necessarily be recoverable.

Thai Civil and Commercial Code Sections 215, 216 and 222 concern damages arising from non-performance, while Sections 387–391 address termination and restoration of the parties to their former positions. The precise remedy remains fact-dependent. Thai Civil and Commercial Code—non-performance and rescission

26. Currency losses can become significant

An international buyer may have transferred money into Thailand years before the delayed transaction is cancelled.

A refund in Thai baht may not restore the buyer’s original:

• US dollar amount
• British pound amount
• Euro amount
• Australian dollar amount
• Singapore dollar amount
• Other foreign-currency value

The buyer may also incur:

• Incoming bank fees
• Currency-conversion spreads
• Outbound remittance charges
• Compliance checks
• Tax-document requirements

The contract should specify the refund currency, payment route, deadline and responsibility for charges.

27. Foreign-funds records should be preserved after cancellation

A foreign condominium buyer should retain:

• SWIFT transfer confirmations
• Bank credit advices
• FET form or qualifying bank certificate
• Developer receipts
• Contract termination
• Refund confirmation
• Outbound-remittance documentation
• Correspondence linking funds to the purchase

These records may be needed to:

• Recover funds
• Remit money out of Thailand
• Redirect funds to another condominium
• Explain the transaction to a Thai bank
• Establish losses
• Support legal proceedings

The buyer should consult the receiving Thai bank before funds are refunded or reassigned.

28. Accepting a new completion date may change the buyer’s rights

A developer may ask the buyer to sign:

• Extension agreement
• Contract amendment
• Revised payment plan
• Delay acknowledgment
• Waiver
• Release
• Settlement
• Revised handover document

The document may contain language confirming that:

• Buyer accepts the delay
• Previous default is waived
• Compensation is surrendered
• New date replaces the old date
• Buyer cannot terminate
• Buyer accepts changed specifications
• Developer has no further liability

An extension may be commercially sensible, but the buyer should receive something meaningful in return and preserve appropriate rights.

29. A negotiated extension should improve the buyer’s protection

Possible protections include:

• New fixed completion date
• Final non-extendable longstop date
• Increased delay compensation
• Suspension of further instalments
• Escrow arrangement
• Bank guarantee
• Developer guarantee
• Mortgage-release confirmation
• Independent monitoring
• Upgraded specification
• Common-fee waiver
• Furniture package
• Rental support after completion
• Refund security
• Buyer termination right

The value of concessions should be compared with the financial risk of continuing.

30. Taking possession before legal completion creates risk

A developer may allow the buyer to occupy the property before formal transfer.

The buyer should clarify:

• Legal basis of possession
• Whether occupation is lawful
• Building-use approval
• Insurance
• Utilities
• Defects
• Common fees
• Rental rights
• Liability for injury or damage
• Developer mortgage
• Refund rights
• Whether possession amounts to acceptance
• Whether warranty periods begin
• Whether delay compensation stops

Physical possession is not the same as registered ownership.

31. Signing a handover form can affect claims

A handover document may state that:

• Property is complete
• Buyer accepts the unit
• No material defects exist
• Delay compensation is settled
• Developer has fulfilled the contract
• Warranty begins
• Final payment is due

The buyer should not sign without:

• Inspecting the unit
• Recording defects
• Checking common areas
• Confirming utilities
• Reviewing completion documents
• Reserving unresolved claims
• Understanding the effect on delay compensation

A snagging list should be attached to the signed handover record.

32. Unit completion does not excuse incomplete common areas

The buyer may receive a completed condominium unit or villa while the project still lacks:

• Swimming pool
• Clubhouse
• Gym
• Roads
• Landscaping
• Security
• Reception
• Beach access
• Drainage
• Water system
• Electricity infrastructure
• Parking
• Promised commercial facilities

The agreement should specify whether completion covers only the private property or also the facilities materially forming part of the purchase.

A buyer should avoid paying the entire price merely because the private unit is habitable if promised essential infrastructure remains unfinished.

33. Developer substitutions require careful review

A delayed developer may offer:

• Another unit
• Another phase
• Different villa
• Smaller property
• Leasehold instead of foreign freehold
• Different completion date
• Credit toward another project

The buyer should compare:

• Ownership
• Title
• Quota
• Area
• View
• Floor
• Layout
• Location
• Facilities
• Completion
• Mortgage
• Rental potential
• Resale value
• Price
• Taxes and transfer costs

The developer should not unilaterally replace the purchased property with a materially different one.

34. Consumer-protection rules may apply

Thailand’s Consumer Protection Act and contract-control measures may affect certain developer transactions.

The Office of the Consumer Protection Board publishes the Consumer Protection Act and related Contract Committee announcements. Its current legal-resource page includes the Announcement of the Contract Committee Re: Designating the Business of Selling Condominium Units with Reservations as a Contract-Controlled Business, B.E. 2567 (2024). Office of the Consumer Protection Board

The precise application may depend on:

• Type of property
• Developer’s business
• Form of agreement
• Whether the purchaser is legally a consumer
• Whether the transaction concerns a condominium reservation
• Date of contract
• Specific contractual terms

Condominium, villa, leasehold and investment arrangements should not automatically be assumed to receive identical protection.

35. A foreign buyer may use Thai consumer procedures

Depending on the facts, possible routes may include:

• Direct developer complaint
• Lawyer’s demand
• Negotiation
• OCPB complaint
• Consumer mediation
• Arbitration, if contractually required
• Consumer Court
• Civil Court
• Insolvency claim
• Settlement

The OCPB provides online complaint and mediation channels and lists its consumer contact service and Call Center 1166. OCPB consumer services

The correct route depends on the contract, developer, remedy sought and urgency.

36. Arbitration clauses can affect the buyer’s strategy

Some developer contracts require disputes to be handled by:

• Thai courts
• Arbitration
• A named arbitration institution
• A particular province
• Another agreed process

The buyer should determine:

• Whether the clause is valid
• Governing law
• Language
• Location
• Appointment of arbitrators
• Costs
• Interim relief
• Enforcement
• Whether consumer law affects the clause

Dispute-resolution wording should be reviewed before signing, not only after a dispute arises.

37. Developer insolvency changes the practical outcome

A contractual refund right is only valuable if the developer has the ability to pay.

If the developer becomes insolvent, the buyer may be:

• An unsecured creditor
• Required to submit a formal claim
• Competing with secured lenders
• Unable to recover the full amount
• Delayed for years
• Offered a restructuring arrangement

The buyer’s lawyer should determine whether:

• Buyer funds were segregated
• Project assets remain
• Land is mortgaged
• Another developer may complete the project
• Creditors have commenced proceedings
• A court-supervised rehabilitation is possible
• The buyer should terminate or preserve the contract
• A claim deadline applies

Delay should be investigated early, before the developer’s remaining assets disappear.

38. Security is more valuable than a refund promise

Possible payment protections may include:

• Escrow
• Bank guarantee
• Parent-company guarantee
• Performance bond
• Construction-linked release
• Lawyer-controlled retention
• Simultaneous final payment and transfer
• Mortgage-release undertaking
• Independent project monitoring

These protections are not automatically present in every Phuket project.

A contractual promise to refund money is unsecured unless supported by assets or a reliable guarantee.

39. The buyer should separate market delay from project failure

A project may be behind schedule but still:

• Own clear land
• Have financing
• Maintain active construction
• Hold necessary permits
• Provide credible reporting
• Have a realistic completion programme
• Cooperate with buyers

Conversely, repeated missed dates combined with stopped construction, hidden mortgages and unpaid contractors may indicate a much higher risk.

The buyer’s decision should be based on evidence, not simply the number of months delayed.

40. Independent legal and technical review is essential

The buyer’s lawyer and, where appropriate, an independent surveyor or engineer should review:

• Contractual completion date
• Grace period
• Longstop date
• Definition of completion
• Force-majeure clause
• Delay-compensation clause
• Payment milestones
• Buyer default provisions
• Termination procedure
• Refund obligation
• Interest
• Damages
• Dispute resolution
• Developer company
• Land title
• Mortgages
• Permits
• Construction status
• Condominium registration
• Title issuance
• Transfer readiness
• Infrastructure
• Financial warning signs
• Proposed amendments
• Waivers
• Handover documents
• Consumer remedies
• Insolvency exposure

The lawyer should explain separately:

• What the developer promised
• What has actually been completed
• Whether the developer is legally in default
• Whether notice is required
• Whether payments should continue
• What remedies are available
• Whether the developer can pay a refund
• What action best protects the buyer

Greg’s professional perspective

A construction delay is not automatically a failed investment. Phuket developments can be delayed by approvals, weather, infrastructure, contractors and other genuine construction issues. The real question is whether the delay remains controlled and whether the buyer’s money and legal position remain protected.

I would focus on five points:

1. Is construction genuinely progressing?
2. Does the developer still have the financial ability to finish?
3. Is the ownership structure and project land secure?
4. Does the contract provide a final deadline and meaningful remedy?
5. How much more money is the buyer required to risk before transfer?

A credible developer should be willing to provide evidence: an updated programme, construction records, permit status, financing information where appropriate and a realistic transfer date.

Repeated promises without supporting documents deserve caution.

The most dangerous arrangement is one where the buyer has paid nearly the entire price, the project is substantially delayed, the land remains mortgaged, the developer controls every extension and the refund promise is unsecured.

The safest response is rarely an emotional cancellation or blind patience. It is a documented, legally reviewed decision based on the contract, title, construction status and developer’s financial ability.
