FAQs Relating to Thailand Mortgage Law

Thailand Mortgage Law governs the creation, registration, enforcement, and cancellation of mortgages in Thailand. A mortgage is a common legal instrument used to secure debts and other obligations by granting a security interest over property without transferring ownership or possession to the lender. Whether you are a lender, borrower, investor, or property owner, understanding Thailand Mortgage Law is essential to protecting your legal and financial interests. This FAQ answers common questions about mortgage registration, enforcement rights, foreclosure procedures, and other important aspects of Thailand Mortgage Law.

What Is a Mortgage Under Thailand Mortgage Law?

Under Thailand Mortgage Law, a mortgage is a contract whereby a person (the mortgagor) grants another person (the mortgagee) a security interest over specific property to secure the performance of an obligation, usually the repayment of a debt.

The mortgagor retains ownership and possession of the property while the mortgage remains in effect. However, if the secured obligation is not fulfilled, the mortgagee may enforce the mortgage and receive payment from the mortgaged property in priority over ordinary creditors.

What Types of Property Can Be Mortgaged in Thailand?

The following types of property may be mortgaged under Thai law:

  • Immovable property, including land, houses, condominiums, and buildings;
  • Registered ships of five tons gross or more;
  • Floating houses; and
  • Registered beasts of burden.

A mortgage must be registered with the competent authority in order to be legally valid and enforceable.

How Does Thailand Mortgage Law Protect Mortgagees?

Thailand Mortgage Law provides mortgagees with a preferential right to receive payment from the mortgaged property before ordinary creditors if the secured obligation is not performed.

This right remains attached to the property even if ownership of the property is subsequently transferred to another person. As a result, the mortgage continues to be enforceable against the property regardless of changes in ownership.

Does a Mortgage Over Land Extend to Buildings Constructed Later?

No. A mortgage over land does not automatically extend to buildings or structures constructed on the land by the mortgagor after the mortgage has been registered.

However, if enforcement proceedings become necessary, the mortgagee may request that the land and any subsequently constructed buildings be sold together. In such circumstances, the mortgagee's preferential right applies primarily to the value of the mortgaged land.

Does a Mortgage Cover the Income or Benefits Derived From the Property?

Generally, a mortgage does not extend to the fruits, income, or benefits generated by the property before enforcement.

Once the mortgagee has notified the mortgagor of the enforcement of the mortgage, however, the mortgage may extend to any fruits or income generated by the property from that point onward.

What Happens If the Mortgagor Defaults on the Secured Obligation?

If the debtor fails to perform the secured obligation, the mortgagee must first provide written notice requiring the debtor to comply.

The notice must allow the debtor at least sixty (60) days to perform the obligation.

If the debtor fails to comply within the specified period, the mortgagee may initiate legal proceedings and request that the court order the seizure and sale of the mortgaged property by public auction.

Can a Mortgagee Foreclose Without a Public Auction?

In certain circumstances, Thailand Mortgage Law allows a mortgagee to seek foreclosure rather than a public auction.

A court may grant foreclosure if:

  • The debtor has failed to pay interest for at least five years; and
  • The mortgagee can demonstrate that the value of the mortgaged property is less than the amount owed.

If the court grants the request, ownership of the property may be transferred to the mortgagee in satisfaction of the debt, subject to the applicable legal requirements.

Can Property Be Mortgaged to Secure Another Person's Debt?

Yes. A person may mortgage property as security for the obligations of another person.

If the mortgage is enforced and the mortgagor satisfies the debt through the mortgaged property, the mortgagor acquires rights against the principal debtor similar to those available to a guarantor under Thai law.

Can a Foreigner Register a Mortgage in Thailand?

Yes. Foreign individuals and foreign companies may generally act as mortgagees and register mortgages over eligible property in Thailand, subject to compliance with applicable laws and registration requirements.

However, a mortgage does not grant ownership of the underlying property. Any enforcement of the mortgage must be carried out in accordance with Thai law and applicable court procedures.

How Is a Mortgage Extinguished?

A mortgage may be extinguished in any of the following circumstances:

  • The secured obligation has been fully performed;
  • The mortgagee releases the mortgage;
  • The mortgage is extinguished by operation of law;
  • The mortgaged property is sold through lawful enforcement proceedings; or
  • Other grounds for extinction provided by Thai law apply.

Once the mortgage has been extinguished, the registration should be formally cancelled with the competent authority.

Must Changes to a Mortgage Be Registered?

Yes. Any modification, discharge, extinction, or amendment relating to a mortgage or the secured obligation should be registered with the competent authority upon the request of an interested party.

Failure to register such changes may prevent them from being enforceable against third parties.
