Inheritance Received Through a Will… Is It Truly Unchallengeable?

มรดกที่ได้ตามพินัยกรรม…ใครก็แย่งไม่ได้จริงหรือ?

Many people believe that “if your name is in the will, that’s the end of it.” However, in legal terms, the matter involves far more detail than that.

The line of Supreme Court Judgment No. 2504/2543 (2000) lays down a clear principle: if the deceased executes a will explicitly bequeath property to any person, that person possesses the rights to the property according to the deceased’s intent. Simply put, if grandparents “intend to leave property to a grandchild” and the will is valid, the rights to that property belong to the grandchild who is the beneficiary.

However, that does not mean everything concludes easily. If other heirs do not accept it, they can “contest” it—for instance, by claiming that the will is invalid, made under coercion or threats, or unlawfully executed. The burden of proof then rests on the contesting party, who must demonstrate these claims to the court.

And what if property is “missing” or hidden? The law considers that if there is concealment, transfer, or failure to disclose estate assets for division, it constitutes an act that infringes upon the rights of other heirs. The result is… the injured party can file a lawsuit in court to trace and recover the assets back to the “estate.”

In short:

  • Having a will = You indeed have rights, but others can still contest them.
  • Concealing estate assets = Risk of being sued; injured parties have the legal right to recover them.

Inheritance is not merely a family matter; it is a “legal right” that must be provable in court.
