Contesting a Will and Inheritance Disputes in Ireland

Discovering that a will leaves you out, or that an estate is being handled in a way that feels wrong, is painful on top of grief. This guide explains, in plain English, the recognised grounds for challenging a will in Ireland, the different routes open to you, and the strict time limits that apply. It sits alongside our wider guide to how probate works in Ireland.

We are a coordinator, not a law firm. The information here is general and synthesised from official Irish sources — it is not legal advice on your situation. Inheritance disputes turn on specific facts and short deadlines, so if you are considering any action, the safest first step is to speak to a solicitor experienced in succession matters.

The main routes to challenge a will or estate decision

In Ireland, contesting a will is not one single action. There are several distinct routes, and the right one depends on who you are and what has gone wrong. Some routes challenge the will itself; others assert a right that exists regardless of what the will says. The table below summarises the main routes and where each comes from in law.

Questioning whether the will is valid

A will is only valid if it was made in the way the law requires. Under Section 78 of the Succession Act 1965, a will must be in writing, signed by the person making it (or by someone at their direction) at the foot or end, and that signature must be made or acknowledged in front of two or more witnesses present at the same time. A will that fails these formalities can be challenged.

A will can also be challenged on the ground that the person did not have testamentary capacity — the mental ability to make it. To have capacity, the person must have understood that they were making a will, broadly what they owned, and who might reasonably expect to benefit. If a serious illness or condition affected this understanding, the will may be open to challenge.

Undue influence is a third ground. This is where someone pressured, coerced, or overbore the will-maker so the document reflects another person's wishes rather than their own. The Irish courts set a high bar here: there must be positive proof of coercion, and the person making the claim carries the burden of proving it.

Fraud and forgery are also grounds — for example, where a signature was forged or the will-maker was deceived about what they were signing. As with capacity and undue influence, the person challenging the will must prove their case, and these claims usually require court proceedings rather than a simple objection.

A spouse or civil partner's legal right share

A surviving spouse or civil partner does not need to attack the will to claim a share. Under Sections 111 and 111A of the Succession Act 1965, they have a legal right share regardless of what the will says: one-half of the estate where there are no children, or one-third where there are children. This right exists independently of the will's terms. (Section 111 covers spouses; Section 111A, inserted in 2011, extends the same entitlement to civil partners.)

Where the will leaves the spouse something, they may have to choose between that gift and the legal right share. Under Section 115, the spouse or civil partner can elect to take the legal right share instead, but must do so within six months of being notified in writing by the personal representative, or within one year of the first taking out of representation — whichever is later.

These rights sit at the heart of many inheritance disputes between surviving partners and other family members. Our guide to spouse and civil partner inheritance rights in Ireland covers how the share is calculated, how electing works in practice, and how the right to the family home fits in.

A child's claim under Section 117

A child has no automatic right to inherit under a parent's will in Ireland. However, Section 117 of the Succession Act 1965 lets a child — including an adult child — apply to court arguing that the parent failed in their moral duty to make proper provision for them, in accordance with the parent's means. The Circuit Court hears most Section 117 applications; the High Court has concurrent jurisdiction for estates where the real property exceeds €3 million.

The court does not simply divide the estate equally. It weighs whether the parent genuinely failed in that moral duty, considering the child's needs and circumstances against what the parent could reasonably have done. The outcome is whatever provision the court thinks is just, which may be a share, a sum, or nothing at all.

When lifetime gifts were used to defeat a share

Sometimes the concern is not the will but a gift made before death. Under Section 121 of the Succession Act 1965, where property was given away within three years before death (or on death) for the purpose of defeating or substantially diminishing a spouse's, civil partner's, or child's share, the court can order that the gift be treated as part of the estate.

This route matters where a person tried to side-step the legal right share or a child's entitlement by handing assets to someone else before they died. As with other claims, it is the person challenging the gift who must satisfy the court of its purpose, and the case is decided in court.

Pausing a grant: lodging a caveat

A caveat is a formal notice that pauses a grant of probate or administration from issuing until the concern behind it is resolved. It is lodged at the Probate Office or the relevant District Probate Registry by a person with an interest in the estate. A caveat buys time to investigate; it does not by itself decide who is right.

A caveat costs €100, remains in force for six months, and can be renewed. The person applying for the grant can “warn” the caveat, after which the person who lodged it must enter an appearance within 14 days. If they do, the caveat stays in place until the dispute is resolved by agreement or by the court.

Before lodging a caveat, it helps to confirm whether a grant has already issued. You can check the public record through the probate register, which shows grants that have been made. If no grant has issued yet, there may still be time to raise a concern before assets are distributed.

When the will is valid but you are worried about how the estate is run

Not every dispute is about the will being wrong. Sometimes the will is valid, but a beneficiary is concerned about how the executor or administrator is handling things — delays, lack of information, or decisions that seem to favour one person. These are estate-management concerns rather than challenges to the will itself.

Beneficiaries have rights to be kept reasonably informed and to receive what they are entitled to within a reasonable time. Our guide to beneficiary rights in Ireland explains what you are entitled to expect and the options if an estate appears to be stalled or mishandled.

Where assets or family members are spread across more than one country, disputes can become more tangled because different legal systems and tax rules may overlap. Our guide to cross-border inheritance and international estates covers the issues that arise when an estate has a foreign element.

Time limits at a glance

Time limits in inheritance disputes are short and, in several cases, applied strictly by the courts. Missing a deadline can end a claim before its merits are ever heard. The table below summarises the key limits, but you should confirm how they apply to your situation with a solicitor.

Getting help with a will dispute

Challenging a will, or defending one, is rarely straightforward. Contested probate is dealt with in the Circuit Court or the High Court depending on the value of the estate. The evidence thresholds for grounds like undue influence are high, and the time limits leave little room for delay. For most people, early legal advice is the difference between a claim that can be properly assessed and one that is lost on a deadline.

We are a coordinator, not a solicitor. What we can do is help you understand where your situation sits, gather the right information, and connect you with a solicitor experienced in succession disputes — so you are not working it out alone while grieving.

Start with a free assessment — it takes about two minutes and there is no obligation. If a will dispute also raises questions about who inherits where there is no valid will, our guide to intestacy in Ireland explains how the estate is then distributed.
