Pretermitted spouse refers to a legal term where a spouse is unintentionally left out of a will. Synonyms for pretermitted spouse include accidental omission of a spouse, undesignated spouse, forgotten partner, left-out mate, undisclosed wife or husband, and unmentioned spouse. In cases where a testator fails to update their will after getting married, their spouse may be pretermitted. Legal procedures for pretermitted spouses may vary based on state laws and the terms outlined in the will. In some cases, pretermitted spouses may still be entitled to a portion of the estate, even if they were not explicitly named in the will.
