Contesting a Will Ireland

Contesting a will in Ireland isn't a general right to challenge how a parent divided their estate. It's a specific legal mechanism with narrow grounds, strict time limits, and real financial risk if you lose. Understanding what works — and what doesn't — before you engage a solicitor can save months of litigation and thousands in costs.

Section 117: The Children's Claim

Section 117 of the Succession Act 1965 allows any child of the deceased — including adult children — to apply to court claiming the parent failed in their "moral duty" to make proper provision for them during their lifetime or under the terms of the will.

The court considers the claim through the lens of what a "prudent and just parent" would have done, taking into account the parent's means and the needs and circumstances of each child. Key factors include:

• Whether the parent provided for the child during their lifetime (education, housing deposits, business support)
• The child's current financial position and needs
• The circumstances of the other beneficiaries
• The overall size of the estate

Crucially, children do not have an automatic right to a fixed share of the estate under Irish law — unlike spouses, who receive a guaranteed Legal Right Share. Section 117 is discretionary, and the court can award anything from nothing to a significant portion of the estate.

The Six-Month Deadline

The most important thing about a Section 117 claim is the time limit: six months from the date the first Grant of Representation is extracted. This deadline is absolute. The court has no power to extend it — not for minors, not for people with disabilities, not for any reason.

The executor has no legal obligation to notify potential claimants of this deadline. A disinherited child who doesn't learn about the grant until seven months after it was issued has permanently lost the right to apply.

The Legal Right Share

Separately from Section 117, a surviving spouse or civil partner has an automatic Legal Right Share that overrides the terms of the will:

• One-half of the net estate if there are no children
• One-third of the net estate if there are children

If the will provides a smaller bequest, the spouse must elect to take either the bequest under the will or the statutory Legal Right Share. The executor must notify the spouse of this right in writing. The spouse has six months from receiving that notice, or twelve months from the grant (whichever is later), to make the election. Failing to elect means the spouse is deemed to take under the will.

This right can be renounced in a separation agreement, which is common in divorce settlements.

Caveats: Blocking a Grant

If you intend to challenge a will's validity — on grounds of forgery, lack of capacity, undue influence, or improper execution — you lodge a Caveat with the Probate Office for a €100 fee. A caveat prevents the Grant of Probate from being issued while the dispute is resolved.

The executor can serve a formal Warning on the caveat-holder, who then has fourteen days to enter an Appearance. If no appearance is entered, the caveat is cleared and the grant proceeds. If an appearance is filed, the dispute escalates to High Court litigation.

Cohabitant Claims

Unmarried partners have no automatic succession rights, but a "qualified cohabitant" (five years of cohabitation, or two years with shared dependent children) can apply to court for a discretionary financial provision under Section 172 of the Civil Partnership and Obligations of Cohabitants Act 2010. This must also be filed within six months of the grant.

Practical Considerations

Section 117 cases are expensive and uncertain. Costs typically run to €10,000–€30,000 or more, and a losing claimant may be ordered to pay the estate's legal costs as well. Before proceeding, consider whether the evidence genuinely supports a finding that the parent failed in their moral duty — the bar is higher than simple unfairness.

The Ireland End-of-Life Planning Guide covers how to structure a will to minimise Section 117 exposure, including the use of a Letter of Wishes to document the reasoning behind unequal provision.
