Match every construction payment to the contract, measured work, signed certification and current site evidence.
A payment date is not proof that work is complete
Map each instalment to the signed contract, drawings, specification and measurable completion test. Request the dated certificate, issuer's appointment and qualifications, inspection basis, photographs, progress report, approved variations and invoice. Confirm that the certified project, phase and unit match your purchase.
Record incomplete or substituted work and ask an independent Thai lawyer and technical adviser whether payment can be withheld, qualified or placed under another agreed control. Use the payment-milestone guide, specification guide and buyer service.
Next step
Phuket Stay Pro can organise the evidence file before an off-plan instalment.
Fact check
Certification duties, authority, construction status, remedies and payment rights depend on the signed documents and current Thai law. Obtain independent legal and technical advice.
