How to Make a Will That Is Legally Valid and Enforceable


Supreme Court Judgment No. 1683/2512

Summary of the Judgment:
In inheritance disputes, any claim to property based on a written record or oral statement of the deceased must strictly comply with the legal requirements governing wills. This Supreme Court judgment confirms that if a document does not bear the testator’s signature or fingerprint, or if an oral will is not reported to the district authority within the period prescribed by law, the disposition is invalid and cannot be relied upon to determine the distribution of the estate. A person who is not a lawful heir likewise has no inheritance rights unless there is another valid legal basis for receiving the property.

In this case, the plaintiff, who was the lawful child of Mr. Sai Sutthiwiset, brought an action seeking recognition of rights in three items of estate property: a house, a rice granary, and one parcel of farmland. The plaintiff argued that the deceased had not made a will leaving the property to anyone else and had orally expressed an intention that the plaintiff alone should receive it.The defendant, who claimed to be the deceased’s wife, argued that there had been a written record dividing the property in the presence of several witnesses. However, that document did not bear the deceased’s signature or fingerprint.The Supreme Court held that the document did not satisfy the statutory requirements for a valid will. Even if it were treated as an oral will, the witnesses had not reported the testamentary declaration to the district authority within the period required by Sections 1663 and 1665 of the Civil and Commercial Code. The purported testamentary disposition was therefore invalid.The Court further held that the defendant had not been legally registered as the deceased’s spouse and therefore did not acquire inheritance rights as a lawful spouse. In addition, there had been no completed transfer of the property during the deceased’s lifetime, so no valid gift had taken effect.Accordingly, the purported written or oral disposition could not be relied upon to transfer the estate property, and inheritance rights had to be determined under the applicable rules governing lawful heirs and valid testamentary dispositions.

A Temple Is a Juristic Person and Its Abbot May Sue to Recover Temple Property from Third Parties


Supreme Court Judgment No. 1387/2500

Summary of the Judgment:
When temple property is taken or retained by outsiders, an important question is whether the temple itself has legal standing to bring an action for its recovery. This Supreme Court judgment confirms that a temple is a juristic person under the law and that its abbot may bring proceedings to recover temple property, even where the property had previously been under the care of a former abbot.
The Court also addressed the validity of a will and held that where the testator later affixes a fingerprint in the presence of the same witnesses, the will may still be valid. However, such a will can operate only over the testator’s personal property and cannot dispose of property belonging to the temple.

Wat Noi Saeng Chan, acting through its abbot, authorized Mr. Maen Chanthai to bring an action against four defendants seeking the return of property listed in the schedule attached to the complaint. The temple alleged that the property belonged to the temple but had been taken and used by the defendants for their own benefit without lawful authority.The defendants argued that the plaintiff had no standing to sue, that some of the listed property did not exist, and that certain items belonged to the former abbot, who had left them to the defendants by will. They also raised a limitation defense.The Supreme Court held that a temple is a juristic person under the Sangha Act B.E. 2484. The abbot therefore had authority to bring proceedings in the temple’s name and could authorize another person to act on the temple’s behalf under Section 60 of the Civil Procedure Code.The Court further held that a will in which the witnesses signed first and the testator affixed a fingerprint three days later in the presence of those same witnesses was valid under Section 1656 of the Civil and Commercial Code. However, the will was effective only in respect of property personally owned by the testator and could not dispose of property belonging to the temple.The Court also held that this was not an inheritance action, but an action to recover temple property held by the defendants without lawful right. The limitation rules applicable to inheritance claims therefore did not apply.The Supreme Court accordingly ordered the return only of property belonging to the temple. Property belonging to Phra Khru Phun or to other persons fell outside the scope of the temple’s claim.

A Surviving Spouse Has a Legal Interest in Estate Proceedings Through Rights in Marital Property, Even If Not Named in the Will


Supreme Court Judgment No. 1089/2529

Summary of the Judgment:
Estate disputes often involve more than the distribution of inheritance. They may also concern who is legally entitled to act as an estate administrator and whether the surviving spouse has an independent ownership interest in marital property. This case illustrates that a lawful spouse may have a direct legal interest in estate proceedings even if the spouse is not named as a beneficiary under the deceased’s will.

This case arose from a dispute between the petitioner, who was the lawful wife of Second Lieutenant Wiboon, the deceased, and the objector, who was the deceased’s elder brother. The objector had previously been appointed estate administrator under a will made in B.E. 2519, under which certain property had been left to him.The petitioner later discovered a subsequent will dated September 28, B.E. 2520, which revoked the earlier will and directed that all of the deceased’s property be presented to His Majesty the King. The petitioner therefore sought the removal of the objector as estate administrator, relying in part on her ownership rights in marital property, which included several assets of substantial value that the deceased could not dispose of by will insofar as they belonged to her.The objector argued that the petitioner had no legal interest because she was not named in the later will.The Supreme Court rejected that argument. It held that the surviving spouse owns one-half of the marital property in her own right. The deceased had no authority to dispose by will of the portion belonging to the surviving spouse.The petitioner therefore had a direct legal interest in the estate proceedings even though she was not a beneficiary named in the will.The Court further considered that the petitioner had previously been appointed as an estate administrator, while the objector no longer had any entitlement to property under the later will. The Court therefore ordered the removal of the objector from the position of estate administrator under Section 1727 of the Civil and Commercial Code.This judgment confirms that a surviving spouse’s rights in marital property exist independently of inheritance rights under a will. The deceased may dispose by will only of property that forms part of the deceased’s own estate and cannot dispose of the surviving spouse’s ownership share in marital property.

What Must Witnesses to a Will Know to Avoid Invalidating the Will?


Supreme Court Judgment No. 4698/2552

Summary of the Judgment:
Making a will involves more than simply recording the deceased’s wishes in writing. The statutory formalities must be strictly observed; otherwise, the will may be void. Defects in the execution of a will may also affect the court’s assessment of whether a person seeking appointment as estate administrator can be trusted to administer the estate properly. This judgment illustrates the principles applied by the Court both to the validity of a will and to the suitability of a proposed estate administrator.

In this case, the petitioner applied to be appointed as estate administrator, relying on a will under which the deceased had left property to the petitioner and other persons. The Court of First Instance initially granted the application. The objector, who was a statutory heir, later challenged the will on the ground that it had not been executed in accordance with the legal requirements.The Supreme Court held that the will relied upon was a public document will under Section 1658 (1) of the Civil and Commercial Code, which required execution in the presence of two witnesses at the same time.However, the witnesses gave conflicting testimony on material points. One witness stated that he did not know that the document was a will and had merely signed a blank document. There was also no clear evidence establishing that the relevant signatures had in fact been made in the presence of both witnesses as required by law.The Court therefore held that the will was void under Section 1705 of the Civil and Commercial Code.Although the petitioner was a statutory heir and was not otherwise legally disqualified from serving as estate administrator, the Court considered that the petitioner’s reliance on a void will had created doubt and distrust among the co-heirs. In the interests of the estate as a whole, the Court therefore exercised its discretion not to appoint the petitioner as estate administrator. This judgment confirms that witnesses to a will must genuinely participate in its execution in the manner required by law. A witness who does not know that the document is a will, signs a blank document, or is not present during the required execution process may cause the will to fail for non-compliance with statutory formalities.

A Will Must Be Executed in the Presence of Witnesses: Later Signatures Render It Void


Supreme Court Judgment No. 11034/2553

Summary of the Judgment:
This case reinforces the principle that the statutory formalities governing a will are not merely technical requirements but essential conditions for its legal validity. Under Section 1656 of the Civil and Commercial Code, an ordinary will must be executed in the presence of at least two witnesses at the same time. If the witnesses sign only later, even after receiving confirmation of the testator’s true intention, the will remains void. The judgment therefore emphasizes the public-order nature of testamentary formalities and their importance in inheritance disputes.

In this case, the plaintiff brought an action seeking a declaration that the deceased’s will was void, arguing that the witnesses named in the will were not present when the document was signed and did not personally see the testator sign it.The defendant argued that although the witnesses had not been present at the time of signing, they later spoke with the testator and received confirmation of the testator’s true intention. The defendant therefore contended that the witnesses understood the deceased’s wishes and had signed the document in good faith.The Supreme Court held that, under Sections 1656 and 1705 of the Civil and Commercial Code, the witnesses must sign the will while present with the testator at the time of execution. If they sign later or did not witness the execution, the statutory formalities have not been satisfied and the will is void. A later confirmation of the testator’s intention cannot cure that defect.The Court further held that although the Court of First Instance had not specifically framed the validity of the will’s formal execution as an issue, the Court of Appeal was entitled to raise and determine it because it involved a question of law concerning public order under Section 225, paragraph two, of the Civil Procedure Code.This judgment confirms that compliance with the statutory formalities of a will is fundamental to its validity. Where those formal requirements are not observed, the will cannot be enforced regardless of subsequent evidence concerning the testator’s true intention.
