English translation

A sale of immovable property is void unless it is made in writing and registered by the competent official. The same rule applies to vessels of five tons and over, to floating houses and to beasts of burden. An agreement to sell or to buy any of the aforesaid property, or a promise of sale of such property is not enforceable by action unless there is some written evidence signed by the party liable or unless earnest is given, or there is part performance. The provisions of the foregoing paragraph shall apply to a contract of sale of movable property where the agreed price is twenty thousand baht or upwards.

Firm annotation

Section 456 is the formality rule for land sales. Without registration at the Land Office (chanote, nor sor 3 gor, etc.), the transaction is void, meaning no ownership transfer occurs even if the buyer paid in full. Two firm-practice points: (1) a private "sale agreement" without registration is enforceable only as a promise to sell (§456 paragraph 2), giving the buyer a damages claim but not title; (2) for foreigners who cannot own land directly, this section reinforces why nominee or trust structures fail, the registered title remains in the nominee's name and is exposed to the nominee's creditors.

Core section

Why this matters in practice

Lawyers: An unregistered sale of land is absolutely void, not merely voidable. However, a preliminary sale agreement (contract to buy/sell) can be enforceable without registration provided written evidence, earnest, or part performance exists. Laypeople: Never pay the full price for land unless the transfer is simultaneously registered at the Land Office, an unregistered transaction gives you no ownership regardless of what you have paid.

Legislative history

Enacted with the Code and later amended by the Act Amending the Civil and Commercial Code (No. 14) B.E. 2548, which is the source of the section as it reads today.

Supreme Court decisions interpreting this section

  1. Supreme Court Judgment No. 1401/2553 (2010) ★ Landmark

    A sale of land not registered with the competent official is void under section 456 paragraph 1. Where the land has no document of title the seller holds only a possessory right, and by delivering the land the seller abandons possession, so the buyer acquires a possessory right by operation of sections 1377 and 1378. That right comes from the taking of possession, not from the void contract, so the buyer may restrain interference with his possession but cannot compel the seller or the seller estate to register a transfer.

    The plaintiffs bought 5 rai of land held under an n.s.3 certificate, paid the price in full, and were put into possession on 12 October 1996; the seller died in 1998 without registering the transfer. They sued her estate administrator for delivery of the n.s.3 and registration of their names. The Supreme Court held the sale void for want of registration under section 456 paragraph 1; but because the land carried no document of title the seller had only a possessory right, and by delivering the land she abandoned it, so the plaintiffs acquired possession under sections 1377 and 1378 by operation of law rather than under the void contract. They therefore could not compel the administrator to register a transfer, and the one-year limitation question under section 1754 paragraph 3 did not arise. Since they did hold possession, the Court ordered the administrator not to disturb it.

  2. Supreme Court Judgment No. 8163/2554 (2011)

    A preliminary agreement to buy or sell land supported by earnest money is enforceable without registration.

    The parties intended to create a preliminary sale agreement supported by earnest money under Section 456 paragraph 2. Such a preliminary agreement does not require registration and is enforceable by action.

  3. Supreme Court Judgment No. 14921/2555 (2012)

    Where the parties to a sale of a vessel of five tons or more intend to register the transfer of ownership once the price is paid in full, the contract is a promise to sell and not an executed sale, so the writing-and-registration requirement of section 456 paragraph one does not apply and the contract is not void for want of registration.

    The contract for the sale of three vessels of five tons or more showed that the seller and the buyer meant to register the transfer of ownership once the buyer had paid in full. The Court therefore classified it as a promise to sell rather than an executed sale, so section 456 paragraph one did not apply and it was not void. A party to a promise to sell need not own the property when the contract is made, since the point of the sale is that the buyer obtains ownership on paying the agreed price and it is for the seller to effect the transfer. As the seller had delivered the three vessels together with powers of attorney to change the registered owner on the day of signing, the contract was enforceable.

Frequently asked questions

Does a sale of land without registration at the Land Office give the buyer any rights?

The sale itself is void: a sale of land or other immovable property that is not registered with the competent official is void under Section 456 paragraph 1, and the buyer acquires no ownership. But it does not follow that the buyer is left with nothing. Where the land carries no title deed and the seller held only a possessory right, a seller who hands the land over abandons possession, and the buyer acquires a possessory right of his own under Sections 1377 and 1378. That right comes from the taking of possession and not from the void contract. So a buyer who has been put into possession of n.s.3 land can assert and defend that possession, and the court will restrain interference with it, but he cannot compel the seller or the seller's estate to register a transfer to him. Where the land is titled land, or where the buyer never took possession, the remedy is limited to recovering the money paid.

Can a verbal agreement to buy land be enforced?

No, unless earnest money was paid or there was part performance. A preliminary agreement (contract to buy/sell) requires at minimum written evidence signed by the party to be charged, earnest money paid, or some act of part performance: otherwise it cannot be enforced in court.
