IrelandWhat is the legal right share of a spouse?
A surviving spouse in Ireland has a legal right share of one-third of the deceased’s estate if there are children, or one-half if there are no children.
What the Law Says
The Succession Act 1965 gives a surviving spouse a guaranteed minimum share of the deceased spouse’s estate — known as the 'legal right share' — regardless of what the will says (or whether there is a will). This protects the spouse from being disinherited.
The legal right share applies automatically — it does not depend on the terms of a will, and cannot be waived unless done so in writing before marriage (e.g., via a valid prenuptial agreement, though such agreements have limited enforceability in Ireland).
It only applies to spouses — civil partners and cohabitants do not have the same automatic right. The share is calculated on the net value of the estate after debts and funeral expenses are paid, but before inheritance tax.
If the deceased leaves children (including adopted children), the spouse’s legal right share is one-third of the estate. If there are no children, the share rises to one-half.
Statutory TextA spouse shall be entitled to a legal right share in the estate of a deceased person who dies wholly or partly testate, that is to say, a share equal to one-third of the net estate if the deceased leaves issue, and one-half of the net estate if the deceased leaves no issue.
— Succession Act 1965, s. 111 — Legal right of spouse
What to Do
Confirm whether the deceased left a will and identify all assets and liabilities of the estate.
Calculate the net estate value (after debts, taxes, and funeral expenses).
Determine whether the deceased left children — this decides whether the spouse’s share is one-third or one-half.
Apply to the Probate Office for a grant of representation if administering the estate, and ensure the legal right share is claimed or accounted for.
Seek legal advice early — especially if the will appears to exclude the spouse or if estate assets are complex (e.g., family businesses or foreign property).
