IrelandHow is the legal right share calculated?
The legal right share in Ireland is calculated as one-third of the deceased’s net estate if the surviving spouse has children, or one-half if there are no children.
What the Law Says
The Succession Act 1965 sets out the legal right share — a guaranteed minimum inheritance for a surviving spouse, regardless of the terms of a will.
The legal right share applies automatically to protect a surviving spouse from being disinherited. It is not a discretionary award but a statutory entitlement.
It is calculated based on the 'net estate' — meaning the value of the deceased’s assets after deducting debts, funeral expenses, and testamentary expenses.
The share depends solely on whether the deceased left children (or their descendants). It does not depend on the length of marriage, cohabitation status, or separation — unless a court has made a proper provision order or the spouse has validly renounced the right.
Statutory TextThe legal right share of a surviving spouse shall be— (a) if the deceased leaves issue, one-third of the net estate; (b) if the deceased leaves no issue, one-half of the net estate.
— Succession Act 1965, s. 111 — Legal right share of surviving spouse
What to Do
Identify whether the deceased left children (or their descendants).
Calculate the net estate: total assets minus debts, funeral costs, and administration expenses.
Apply the correct fraction: one-third (with children) or one-half (no children).
Lodge a claim with the personal representative (executor or administrator) within the time limits for probate proceedings.
If disputed, apply to the Circuit Court or High Court for determination — though no court case references are provided here.
