Contesting a will in Ireland

This page is an exception to the rest of this site. Every other page covers aspects of probate where a personal applicant with the right preparation can realistically do the work themselves. This one does not. Will contests in Ireland are contested civil litigation, and the party who tries to run one without a solicitor will lose not because their case is weak but because the procedure defeats them.

ProbatePack does not sell a product that addresses will contests. The right response is a solicitor experienced in contentious probate.

The rest of this page is published so that anyone landing on it from a Google search has an honest summary of what is involved and why the solicitor route is the only viable one.

The main grounds for contesting a will

Under Irish law, a will can be challenged on any of the following grounds.

Section 117 of the Succession Act 1965

Section 117 allows a child of the deceased to apply to court for proper provision where the parent has failed in their moral duty to make reasonable provision for the child.

This is the most common and most legally-developed ground for will contests in Ireland. The test is not whether the child was treated equally with other children, but whether the provision made for the child was fair in the circumstances, considering the child's age, needs, means, and the overall size and shape of the estate.

Section 117 claims must be brought within six months of the Grant of Probate or Grant of Administration with Will Annexed issuing. After that deadline, the claim is statute-barred. This short window is why anyone considering a Section 117 claim needs to move quickly to retain a solicitor.

Lack of testamentary capacity

A will is valid only if the person making it had the mental capacity to understand what they were doing. The legal test (from the English case Banks v Goodfellow, adopted in Irish law) requires the testator to:

1. Understand the nature of the act of making a will
2. Understand the extent of the property being disposed of
3. Understand the claims of those who might reasonably expect to inherit
4. Not be suffering from any disorder of mind that influences the disposition

If the testator lacked capacity at the time of signing (typically because of dementia, delirium, or severe mental illness), the will is invalid and the estate passes under the previous will, or under intestacy if no previous will exists.

Capacity challenges typically require expert medical evidence, contemporaneous records from the time of signing, and witness testimony. They are evidentially intensive.

Undue influence

A will procured by coercion or manipulation of the testator is invalid. The bar is high: general encouragement, persuasion, or pressure does not meet the legal test. Undue influence means actual coercion or manipulation of such force that the will does not represent the testator's true intentions.

Undue influence claims are rare and hard to prove. The evidence typically includes: unusual patterns of isolation of the testator from other family, sudden changes to long-established intentions, significant benefit to the alleged influencer at the expense of expected beneficiaries, and circumstances surrounding the signing of the will.

Forgery

A will that is not genuinely signed by the testator is void. Forgery cases include fabricated wills, wills signed by someone other than the testator, and wills where the testator's signature was obtained by fraud. These cases require handwriting analysis and can involve criminal proceedings in addition to civil probate litigation.

Failure to comply with formalities

A valid will in Ireland must be:

• In writing (paper or other durable form)
• Signed by the testator, at the foot or end of the will
• Signed in the presence of two witnesses, both present at the same time
• Signed by both witnesses in the presence of the testator

Any failure of these formalities renders the will invalid. Typical defects: the testator signed but the witnesses were not present together; one witness signed at a later date; the testator did not physically sign but made a mark without the required additional witness attestation; the will was signed above the substantive text, leaving room for subsequent unauthorised additions.

Formal defects are often discovered only when the will is lodged with the Probate Office. The Probate Officer reviews the document and raises queries on apparent defects. In clear cases the will is rejected and intestacy applies.

The process for contesting

Contested probate in Ireland proceeds through the Circuit Court or High Court depending on the value of the estate. Typical stages:

1. Solicitor engagement. The challenger instructs a solicitor and formally asserts their position.
2. Caveat. A solicitor files a caveat with the Probate Office, which prevents any Grant issuing until the dispute is resolved. Caveats expire after six months but are renewable.
3. Correspondence. The parties (challenger, executor, main beneficiaries) exchange solicitor correspondence setting out their positions. Many disputes are settled at this stage.
4. Probate proceedings. If no settlement, the matter proceeds to formal court proceedings. The challenger files a specific pleading depending on the ground of challenge (Section 117 application, capacity challenge, etc.).
5. Discovery and evidence. The parties disclose documents, witness statements are exchanged, medical experts are instructed.
6. Hearing. The court hears evidence. In complex cases this can run for several days.
7. Judgment and costs. The court rules. The losing party typically pays the winning party's costs in addition to their own.

Typical timeline for a contested will case: 18 months to 4 years from first challenge to final determination, assuming the matter does not settle earlier. Typical cost for a party: €25,000 to €150,000 in legal fees, depending on complexity and whether expert evidence is required.

When contesting makes sense

Not every perceived unfairness justifies a will contest. A challenger should consider:

1. Is the ground plausible? Section 117 claims by children who were provided for at all are often unsuccessful. Capacity challenges without strong medical evidence rarely succeed. Undue influence claims without evidence of coercion rarely succeed.
2. What is the realistic outcome if you win? A Section 117 claim rarely awards a majority of the estate; typically the court awards a portion appropriate to the child's needs. A capacity challenge that succeeds may mean intestacy, which might or might not benefit the challenger.
3. Can you afford the cost? Legal fees for a will contest usually run to tens of thousands. Legal aid is not generally available for probate matters.
4. What is the relationship cost? Will contests destroy family relationships. Siblings who sue each other over an estate rarely reconcile afterwards. This cost is often the largest.

For many people considering a contest, the right answer is to consult a solicitor for a one-hour assessment before committing to a formal challenge. A reputable solicitor will give an honest view of the prospects and the cost.

What ProbatePack does not do

ProbatePack prepares personal applicants for standard probate. It does not prepare anyone for contested probate. If you have a will contest on your hands, either as the executor defending a claim or as a potential claimant considering one, ProbatePack products will not help you. A solicitor with experience in contentious probate is the only realistic route.

When SolicitorCompare.ie launches (planned for later in 2026), it will include a specific panel for contentious probate solicitors. In the meantime, the Law Society of Ireland maintains a find-a-solicitor service that filters by practice area.

The Readiness Check is still useful

If you are the executor of an estate where a potential challenge is possible but not yet formal (for example, a family member has expressed disagreement but has not yet retained a solicitor), the Readiness Check can still identify the threat of contest as a flag that elevates the overall complexity of the estate. The report will recommend you consult a solicitor rather than attempt a personal application.
