Property Disputes in Thailand: Common Legal Issues.

Property disputes in Thailand: where they start

Most property disputes in Thailand start in one of two places: a contract someone didn't honour, or a boundary someone didn't check. Foreign owners and buyers see the contract kind most often, because so much of their exposure runs through sale agreements, off-plan purchase contracts, and leases.

The pattern across all of them is consistent. The dispute is decided by what was signed and what was registered, not by what was said in the sales office. That is why the cheapest dispute is the one prevented before the purchase. It is also why the first question any property dispute lawyer asks is "can you send me the contract?"

Here are the disputes that come up most, and how each one tends to resolve.

Breach of sale and purchase contracts

The classic case: a buyer pays a deposit and the seller backs out, finds a higher offer, or cannot deliver clean title. Or the reverse: the buyer walks and wants the deposit back.

Thai law gives the wronged party real remedies, including forfeiture or return of the deposit, damages, and in some cases an order compelling the transfer. Which remedy applies depends on the contract's wording: what counts as default, what notice is required, and what happens to the deposit in each scenario.

Two practical points decide most of these cases:

• The paper trail. Payment records, the signed agreement, and written communications. A transfer slip with no contract behind it is a weak position.
• Who defaulted first. Contracts often fail in stages, and the party who can show they performed their side on time usually holds the stronger hand.

A lawyer reviewing the sale and purchase agreement before signing costs a fraction of litigating it afterwards.

Off-plan and developer disputes

Off-plan purchases generate a steady stream of disputes: projects delivered late, built to different specifications, or never finished at all. Buyers have paid in instalments against a promise, which makes the contract and the developer's solvency the whole game.

Buyer-versus-developer cases often qualify as consumer cases, which run on a simplified, lower-cost court procedure designed to be accessible for the consumer. Typical claims are refunds of instalments with interest, contractual late-delivery penalties, and termination.

Timing matters more here than in any other dispute type. When a project stalls, the buyers who send demand letters and file early are the creditors who recover; the ones who wait for the developer's next reassuring newsletter recover less. The off-plan buying guide covers the checks that keep you out of this section entirely.

Deposit and earnest-money disputes

Smaller in value but high in volume: reservation fees on units that fall through, security deposits on leases withheld at move-out, earnest money kept after a financing condition failed.

Most of these resolve without court, through a written demand, then a lawyer's demand letter, then for residential tenancies a complaint to the consumer protection authorities. The escalation ladder and the rules on lawful deductions are covered in the rental deposit guide.

Boundary and encroachment disputes

Land disputes between neighbours are common in Thailand, especially outside city centres where older surveys and lower-grade title documents leave room for disagreement. Typical cases: a fence or building over the boundary line, a blocked access way, or two deeds that appear to cover overlapping land.

The Land Office is the first stop, because it holds the survey records and can re-survey the boundary. Many disputes end there, with an official measurement both sides accept. The ones that continue go to civil court, where the grade of title matters: a Chanote with GPS-surveyed boundaries is much harder to attack than a possessory claim.

If you are buying land or a villa, this is the dispute category that due diligence prevents outright. A title search and boundary check before transfer costs little; moving a house does not.

Condo and juristic-person disputes

Condo ownership comes with a co-owners' community and a juristic person that manages the building. Disputes cluster around common-area fees and penalties, management decisions, sinking-fund spending, and meeting votes.

The Condominium Act sets the framework: what the juristic person can charge, what majorities decisions need, and what rights individual co-owners have. Most conflicts settle in the co-owners' meeting once someone reads the Act and the building's regulations carefully. The ones that don't, such as a manager refusing to issue the debt-free certificate needed for a condo title transfer, can end up in court or before the authorities.

Lease and land-use disputes

Long leases and registered rights generate their own conflicts: landlords refusing to honour renewal promises, disagreements over maintenance obligations, early termination, and rights that were promised but never registered. The recurring lesson is the one from the leasehold vs freehold guide: registered terms bind successors, unregistered side promises bind only the person who made them, and disputes expose the difference.

How disputes actually get resolved

Thai property disputes run up a familiar ladder:

1. Negotiation. Direct, documented, in writing. Most disputes end here, especially once both sides have priced the alternative.
2. Demand letter. A formal letter from a lawyer stating the claim, the legal basis, and a deadline. It signals that the next step is real.
3. Mediation. Often tested before filing, especially where the parties still need each other. Private mediation is available through institutions such as the Thailand Arbitration Center, and mediated settlements can be made enforceable when documented correctly.
4. Court. Civil litigation at first instance commonly takes a year or more; consumer cases are faster. Foreigners litigate property claims in Thai courts routinely, through Thai counsel, with translated documents.

Where the dispute and the property sit also shapes lawyer selection. For Bangkok condos and developer cases, local experience with the same developers and juristic persons can matter.

When to bring in a lawyer

Earlier than feels natural. The moment a counterparty stops performing, starts renegotiating signed terms, or goes quiet, the documents you create next will either help or haunt the case. A short consultation gets the paper trail pointed the right way before positions harden.

You can compare lawyers on Justenda, message them directly, and ask about fee structures: demand letters are usually fixed-fee, litigation is commonly staged. For disputes still at the contract stage, a property lawyer can often settle the matter with one well-aimed letter.
