Verbatim from the Royal Gazette / Office of the Council of State

English translation

In order to enforce a mortgage, the mortgagee must first serve a written notice on the debtor requiring payment within a reasonable time, which must not be less than sixty days from the day on which the debtor receives that notice. If the debtor neglects to comply with the notice, the mortgagee may bring an action in court for a judgment ordering the seizure of the mortgaged property and its sale by public auction.
In the case under paragraph one, where the mortgagor has mortgaged their own property to secure a debt which another person must pay, the mortgagee must send that notice to the mortgagor within fifteen days from the day on which the notice was sent to the debtor. If the mortgagee does not do so within that period of fifteen days, that mortgagor is discharged from liability for the interest and compensation owed by the debtor, and for the accessory charges attaching to that debt, arising from the day on which the period of fifteen days expires.

Firm annotation

Section 728 was repealed and replaced in its entirety by section 12 of the Act Amending the Civil and Commercial Code (No. 20) B.E. 2557, which came into force on 11 February 2015. Two requirements date from that replacement. First, the notice must allow the debtor at least sixty days, counted from the day the debtor receives it, so a notice allowing less, or no notice at all, does not satisfy the section. Second, paragraph 2 provides that where the mortgagor pledged their own property to secure a debt owed by another person, the mortgagee must send that mortgagor the same notice within fifteen days of sending it to the debtor, failing which that mortgagor is discharged from the interest, compensation and accessory charges accruing after that fifteen day period expires. Note the asymmetry: the sixty days run from RECEIPT by the debtor, the fifteen days from DISPATCH to the debtor. Section 714/1, added by the same Act, makes void any agreement about a mortgage that differs from sections 728, 729 or 735, so these notice requirements cannot be contracted out of. By section 22 of that Act the amended section applies to enforcement of a mortgage taken from the day it came into force, including under mortgages made earlier. Supreme Court decisions on the former text, including those on this page, must be read subject to these requirements.

Core section

Why this matters in practice

Lawyers: The written notice is a mandatory prerequisite to enforcement, and the period it allows must be at least sixty days counted from the day the debtor RECEIVES it, so the mortgagee needs to be able to prove receipt and not merely dispatch. Paragraph 2 counts differently: the fifteen days for notifying a third-party mortgagor run from the day the notice was SENT to the debtor. Diarise that fifteen day deadline, because missing it discharges that mortgagor from the interest, compensation and accessory charges accruing afterwards. Section 714/1 makes void any mortgage agreement that differs from sections 728, 729 or 735, so a clause shortening the sixty days, or deeming a notice delivered without actual receipt, falls within that provision. Laypeople: Before a lender can take your mortgaged property it must first send you a written demand giving you at least sixty days to pay, counted from when you receive it. If you receive one, act quickly, take legal advice and try to negotiate.

Legislative history

Section 728 was repealed and replaced in full by section 12 of the Act Amending the Civil and Commercial Code (No. 20) B.E. 2557, in force 11 February 2015. That replacement introduced the sixty day minimum notice period and the whole of paragraph 2 on a mortgagor who pledged their own property for another person's debt. The same Act added section 714/1, which makes void any agreement about a mortgage differing from sections 728, 729 or 735. The later Act Amending the Civil and Commercial Code (No. 21) B.E. 2558 revisited other provisions of the same reform but did not touch section 728.

Supreme Court decisions interpreting this section

  1. Supreme Court Judgment No. 7151/2544 (2001) ★ Landmark

    Section 728 lays down no required contents for a notice of foreclosure; it says only that before enforcing, the mortgagee must send the debtor a letter requiring payment within a reasonable time fixed in the notice. A notice is therefore effective in law if its wording lets the mortgagor understand that foreclosure has been noticed. Here it gave the wrong title-deed numbers for seven of the eight mortgaged plots but identified the loan contract correctly, and the mortgagor own defence showed she understood which mortgages were being enforced, so it was good for all eight.

    A bank sued on a loan secured by mortgages over eight title deeds in Phuket. The notice of foreclosure attached to the plaint gave the correct deed number for only one of the eight plots, but referred correctly to the loan contract. The first court allowed enforcement against that one plot alone. The Supreme Court held that section 728 prescribes no particular contents for the notice, requiring only a letter calling on the debtor to pay within a reasonable time, so a notice is effective if its wording lets the mortgagor understand that foreclosure has been noticed. The mortgagor had never pleaded that the other seven plots were not covered; her defence was that the signatory had no written authority, which showed she understood every mortgaged plot was being enforced. The notice was therefore effective for all eight, and enforcement was allowed against the remaining seven.

  2. Supreme Court Judgment No. 5553/2542 (1999)

    A notice of foreclosure under section 728 is a declaration of intention that must reach its addressee, and the addressee the law designates is the mortgagor. Where the mortgagor had already died when the notice was sent, it is bad even though someone else took delivery of it. On death the estate, including the deceased rights, duties and liabilities, passes to the heirs under sections 1599 and 1600: if the mortgaged property has been transferred, the mortgagee must give the transferee one month written notice under section 735; and if no transferee has yet appeared but there are heirs or an administrator, they stand in the position of a transferee and must be given at least one month written notice before enforcement. Filing the action is not itself a notice of foreclosure.

    A bank sued the borrower, a guarantor and two heirs of the mortgagor for just over one million baht and to enforce the mortgage. The mortgagor had died before the bank sent its notice of foreclosure, although another person took delivery of it. The Supreme Court held the notice to be a declaration of intention which must reach the mortgagor, so delivery to someone else did not make it good; that on her death her rights, duties and liabilities passed to her heirs under sections 1599 and 1600; that a transferee of mortgaged property must be given one month written notice under section 735 and, where no transferee has appeared, heirs or an administrator stand in the same position and are entitled to the same month notice; and that suing the heirs is not itself a notice of foreclosure. Having given the heirs no notice before suing, the bank had no standing to enforce the mortgage, although the money judgment stood with the heirs liable only to the extent of the estate that came to them.

  3. Supreme Court Judgment No. 938/2542 (1999)

    A notice of foreclosure under section 728 sent by registered post with return receipt both to the address the mortgagor gave in the mortgage contract and to his actual domicile is taken to have been received and known of by him, so the mortgagee may sue to enforce. Separately, once the lender terminates the loan and gives the notice of foreclosure, its contractual right to raise the interest rate comes to an end on that date; it cannot rely on a later rate announcement of its own to claim a higher rate than it was entitled to charge when that right expired.

    A bank sued to recover a loan and enforce a mortgage over land held under an n.s.3 kor certificate, claiming interest at 25 percent a year. The rider to the mortgage provided that any notice sent to the address the mortgagor had given, by hand or by post, registered or not and whether or not anyone received it, was to be treated as duly delivered. The bank sent the notice of foreclosure both to that address and to the mortgagor home, in each case by registered post with return receipt. The Supreme Court held he was therefore to be treated as having received and known of the notice, that a reasonable period to pay had been allowed, and that the bank could sue to enforce under section 728. On interest it held the bank right to raise the rate ended when it terminated the loan and gave the notice of foreclosure on 2 September 1996; under its own announcement then in force it could charge at most 19 percent, and it could not rely on its 1998 announcement to claim 25 percent. The 25 percent was not a penalty the court could reduce under sections 379 and 383, but a contractual rate whose foundation had already lapsed.

Frequently asked questions

How much advance notice must the bank give before it can seize my mortgaged property?

Section 728 requires the mortgagee to serve a written notice requiring payment within a reasonable time, and that time must not be less than sixty days from the day the debtor receives the notice. Only if the debtor does not comply may the mortgagee bring an action for seizure and sale by public auction. Where the property was mortgaged to secure a debt owed by another person, the mortgagee must also send the notice to the mortgagor within fifteen days, failing which that mortgagor is discharged from interest and accessory charges arising after that period.
