Testator (fem. testatrix) meaning

The person who makes and executes a will or codicil disposing of their estate on death. In practice, “testator” identifies the will‑maker in drafting, probate and estate administration, and in disputes concerning testamentary capacity, knowledge and approval, undue influence, proper execution and revocation. Usage is broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland. In England & Wales and Northern Ireland the term is used throughout the Wills Act 1837 and the Wills and Administration Proceedings (Northern Ireland) Order 1994 without a separate statutory definition. In Ireland, “testator” (including “testatrix”) is defined in the Succession Act 1965. Scots law uses the term descriptively alongside “will” or “testamentary writing”. Key features: the testator must have capacity and intention, and comply with the relevant formalities; they may appoint executors, make gifts and create testamentary trusts. After death, the estate is administered according to the testator’s last valid will, subject to any statutory family provision regimes. Jurisdictional note: age and execution requirements vary (for example, Scotland recognises testamentary capacity from age 12, whereas England & Wales, Northern Ireland and Ireland generally require 18, subject to limited exceptions). “Testatrix” is traditional; modern drafting typically uses the gender‑neutral “testator”.
