The Succession Act 1965 Explained in Plain English

1. What happens if there is no valid will?

The intestacy rules determine who receives the estate. Under section 67, a surviving spouse with no children takes the whole estate. Where there is a spouse and children, the spouse takes two-thirds and the children share one-third. Where there are children but no spouse, the children inherit under the statutory rules.

If there is no spouse or issue, later sections deal with parents, siblings and more remote next-of-kin.

See the worked examples in What Happens If You Die Without a Will in Ireland?

2. What makes a will valid?

Sections 77 and 78 deal with capacity and execution. A will must be made by a person with the required age and testamentary capacity, be in writing and be signed or acknowledged while at least two witnesses are present at the same time. Each witness signs in the testator's presence.

Section 82 is also important: a gift to an attesting witness, or to the witness's spouse, can be void as regards that person. That is why independent witnesses are the sensible choice.

3. What happens to a will when you marry?

Section 85 provides that a later marriage generally revokes an earlier will unless it was made in contemplation of that marriage, subject to a statutory exception involving certain marriages between existing civil partners.

Marriage is therefore one of the clearest reasons to review an existing will.

4. What is a spouse's legal right share?

Section 111 gives a surviving spouse a legal right to one-half of the estate where the testator leaves no children and one-third where there are children. The right has statutory priority over ordinary gifts under the will.

Civil partners have corresponding legal-right provisions inserted into the succession legislation by the 2010 Act.

5. Do children have a guaranteed percentage?

No. Section 117 is different from the spouse's legal right share. A child of a testator may apply to court where the testator is alleged to have failed in the moral duty to make proper provision for that child in accordance with the testator's means.

The court approaches the application from the point of view of a prudent and just parent and considers the circumstances. It is not an automatic right to an equal share.

The current statutory deadline is important: an application must be made within six months from the first taking out of representation of the estate.

Does the Act mean you cannot choose who inherits?

No. A will still gives substantial control over executors, beneficiaries, residue, specific gifts and family arrangements. The Act creates legal boundaries and protections around that freedom.

The useful way to think about it is: your will sets out your plan, but the plan operates within Irish succession law.

What is outside the Succession Act?

Not every estate-planning issue is answered by this Act. CAT is governed by separate tax legislation. Pensions, jointly owned assets, foreign property, company shares and decision-support arrangements can raise different legal regimes.

That is why a straightforward will can be straightforward while a complex estate still needs professional advice.
