Spousal share describes, in practice, the portion of property a surviving spouse or civil partner is entitled to on death, or (colloquially) the share allocated on divorce. It is not a defined term in UK or Irish legislation, but a descriptive expression used across succession and family law.England & Wales: on intestacy, the spouse/civil partner takes personal chattels, a statutory legacy (a fixed sum set by secondary legislation) and some or all of the residue; if there are children or other issue, they take half the residue, otherwise generally the whole estate. If there is a will, there is no fixed spousal share, but the spouse may claim reasonable financial provision under the Inheritance (Provision for Family and Dependants) Act 1975.Northern Ireland: a similar intestacy structure applies, but where there are no issue and parents/siblings survive, they may still share the residue with the spouse; statutory legacy amounts are set by order.Scotland: the concept maps to statutory prior rights (dwellinghouse, furnishings and a cash sum) and legal rights in the moveable estate (one-third if issue exist; one-half if none), whether or not there is a will.Ireland: the Succession Act 1965 provides a legal right share (one-half if no issue; one-third if issue) against a will; on intestacy the spouse takes all if no issue, or two‑thirds if there are issue.
