Buying a Condo in Thailand, Step by Step

A condominium can be a lawful freehold route for a qualifying foreign buyer, but the quota, title, money trail and transfer documents must line up. Treat the sequence below as preparation for independent legal advice, not a substitute for it.

This checklist begins after the household has compared renting with ownership. If that choice is still open, use the rent-or-buy condo decision before paying for a transaction.

Step 1 — Rent before buying

A holiday does not reveal night-time noise, management quality, flooding, traffic or the real cost of daily transport. Rent in the building or immediate area first where possible, then use the renting checklist before committing.

Step 2 — Confirm the foreign quota correctly

Foreign ownership is limited by the building’s aggregate unit area, not simply by counting units. Ask the condominium juristic person for current written confirmation that the proposed unit can be registered within the foreign quota. Your lawyer should verify the evidence rather than relying on a sales statement.

The confirmation must be current for the proposed transfer. A building within quota when advertised can reach the limit before completion. Make quota availability a contract condition with a clear refund remedy.

Step 3 — Appoint your own lawyer

Use a lawyer who acts for you, independently of the seller, agent and developer. Before sharing the full file or paying an advance, use the lawyer licence, scope and fee checklist to verify the named individual and written engagement. The property review should cover at least:

• the title and seller’s authority to sell;
• mortgages, court orders or other encumbrances;
• outstanding common fees and other liabilities;
• the building’s quota evidence; and
• contract terms, completion conditions and allocation of taxes and fees.

Match the unit number, floor, registered area, owner and common-property ratio on the title to the physical unit. Balconies, parking, storage or merged rooms may not have the legal status suggested by a listing.

Audit the building, not only the room

Ask the condominium juristic person for records your lawyer can assess:

• registration and current manager authority;
• regulations and house rules;
• recent audited accounts, budget and reserve balance;
• general-meeting minutes and special assessments;
• building and common-area insurance;
• arrears, litigation and contractor disputes; and
• planned structural, lift, façade or utility work.

Walk the service areas. Check water pressure, drainage, lifts, fire exits, generator coverage, waste handling, parking and water ingress. Speak to owners who are not involved in the sale.

Step 4 — Agree the contract only after due diligence

Do not let a reservation deadline replace legal review. The written agreement should identify the unit, price, payment schedule, included contents, completion documents, default remedies and who pays each transfer cost.

It should make completion conditional on valid foreign-quota and debt-clearance evidence, state the title and encumbrances the seller must deliver, identify the agreed bank-evidence route, allocate risk before handover, and explain what happens if either party cannot lawfully complete.

For an off-plan unit, add construction milestones, approved specifications, completion evidence, defect retention, common-area delivery and developer-default protection. Marketing renders are not contractual specifications.

Treat a reservation as a contract decision

A small reservation payment can create a large practical problem if the receipt says “non-refundable” before quota, title, finance or legal review. Before paying, require a document that identifies:

• the developer or seller’s exact legal name and the authorised recipient;
• project, building, floor, unit number, registered or expected area and price;
• the due-diligence, finance and foreign-quota conditions;
• the deadline for the full contract and the documents to be supplied;
• when either side may cancel and the exact refund deadline; and
• whether the amount is held, credited to the price or treated as a fee.

Do not rely on a salesperson’s explanation that an unfavourable printed term “is never enforced.” Put every material promise into the signed document or an attached schedule reviewed by your own lawyer.

Add the current consumer-contract check for developer sales

Thailand’s Office of the Consumer Protection Board said in June 2026 that condominium sale contracts with consumers are a controlled-contract business. Its guidance highlights clear construction-completion and ownership-transfer dates, advises recording verbal promises in writing and warns buyers to keep advertising material as evidence.

For a new-build or off-plan purchase, have the lawyer check the current controlling notification and contract form—not only the developer’s draft. The OCPB guidance also describes remedies for developer delay and warranty periods of five years for principal structural elements and one year for other components, counted from transfer. Do not apply those figures mechanically to every resale, commercial buyer or factual dispute; confirm the current instrument and the buyer’s legal position.

Save the brochure, web listing, floor plan, specification, show-unit claims, payment receipts and every contract version. Date screenshots and export important pages as PDF. A promise is easier to assess when the exact words and date are preserved.

Step 5 — Confirm the bank-evidence route before moving funds

Do not describe an FET document as the only route. Department of Lands rules also recognise specified evidence involving withdrawals from a non-resident baht account or a foreign-currency deposit account. The correct evidence depends on how the funds enter or are held and on what the receiving Land Office will accept for the transaction.

Before transferring, ask your lawyer, receiving bank and Land Office to confirm in writing:

• the qualifying evidential route;
• the sender, beneficiary and payment-purpose wording;
• whether one or several bank documents will be issued; and
• how the purchase price and any currency conversion should appear.

Keep the sending-account statement, SWIFT or transfer confirmation, Thai credit advice, exchange record and bank certificate together. Do not route purchase money through an agent, lawyer or other third party merely for convenience without written legal, bank and Land Office confirmation.

Step 6 — Register at the Land Office

The ownership transfer is completed at the relevant Land Office after the required title, quota, bank and contractual documents are accepted and the applicable taxes and fees are paid. Do not publish or rely on a generic fee split: the legal charge and the parties’ contractual allocation are separate questions.

Before transfer day, obtain a completion statement showing the price paid, balance due, each tax or fee, common-fee adjustment, agent fee and payer. Verify current legal charges against the Department of Lands schedule because temporary measures can change.

At completion, check the title endorsement, passport details, unit number, registered price, encumbrances and official receipts before leaving. Retain certified copies of bank evidence and every document surrendered.

Step 7 — Handover and preserve the file

Use a dated handover record for keys, access cards, meters, inventory, defects and utility readings. Notify the juristic person of ownership and obtain written common-fee payment instructions.

Keep permanently: title and Land Office receipts, contract and completion statement, foreign-funds evidence, quota and common-fee certificates, seller authority, regulations, handover inventory, and succession advice covering the Thai asset.

For a developer handover, inspect before signing an unconditional acceptance where the contract allows. Photograph meter readings and every defect with a scale and location reference. Send one numbered defect schedule through the contract’s notice route, record access given for repairs and obtain written close-out. A chat thread without the contract unit number, date or recipient is weak evidence.

If the transaction starts to fail

Separate the problem before choosing a remedy:

Problem	First evidence to preserve
Quota or title cannot be delivered	Lawyer’s search, juristic-person certificate, seller statement and contract condition
Construction or transfer is late	Contract dates, payment record, dated site evidence and formal notice
Unit differs from plan or promise	Signed specification, advertising copy, approved plan and measured handover record
Defects are not repaired	Numbered defect schedule, photographs, access history and written responses
Deposit or refund is withheld	Receipt, refund clause, cancellation notice and payment trail

Use the contract’s notice method and get Thai legal advice before terminating, withholding a payment or signing a substitute agreement. For a developer-consumer dispute, the OCPB currently points consumers to its website, OCPB Connect and hotline 1166. A complaint channel does not preserve a contractual deadline automatically.

Red flags that justify stopping

• the seller, agent and “your lawyer” share the same commercial interest;
• title owner and payment recipient do not match;
• quota is promised verbally but not certified;
• a deposit is non-refundable before independent review;
• the unit contains unregistered alterations or occupied common space;
• building financial and meeting records are withheld;
• money must pass through an unexplained third-party account;
• a nominee company is suggested to bypass ownership rules; or
• you are asked to declare a false price or payment purpose.

Pause and resolve the evidence. Losing a reservation can be cheaper than acquiring a disputed or non-transferable asset.

Model the exit before buying

Include common fees, special assessments, insurance, refurbishment, vacant periods, resale time, currency risk and the cost of maintaining the unit if health or visa plans change. Compare that total with several years of renting—not only today’s rent.

The bottom line

The safe sequence is quota, independent due diligence, contract, confirmed bank evidence, then registration. Do not transfer a large sum because a seller says an FET is always enough—or always the only option. Confirm the exact route before the money moves.
