A person who inherits by operation of law rather than under a will (ทายาทโดยธรรม). Section 1629 sets six classes, in order: descendants; parents; brothers and sisters of full blood; brothers and sisters of half blood; grandparents; and uncles and aunts. A surviving spouse is a statutory heir alongside these classes, with a share that varies according to which class inherits (Section 1635). A valid will displaces this order. See making a will in Thailand and dying without a will.
