Contesting a Will in Ireland — Grounds, Process and Costs

Contesting a will — or having a will challenged against you — is one of the most stressful and expensive legal processes an Irish family can face. This guide explains the legal grounds for challenging a will in Ireland, the process, and what to expect in terms of time and cost.

Can You Contest a Will in Ireland?

Yes. Any person with a legitimate interest in an estate — a beneficiary, an excluded family member, or a creditor — may challenge the validity of a will through the courts. However, the legal threshold for successfully challenging a will is high; a will cannot be overturned simply because you feel it is unfair.

Grounds for Challenging a Will in Ireland

Lack of Testamentary Capacity

The testator must have had the mental capacity to make a will at the time of signing. If they were suffering from dementia, severe mental illness, or substance-induced incapacity, the will may be invalid. Medical records are crucial evidence in these cases.

Undue Influence

If the testator was coerced, pressured, or manipulated into making the will as they did, the will (or affected provisions) may be set aside. This is notoriously difficult to prove — mere persuasion or family pressure is not enough; the influence must have overcome the testator's free will.

Fraud or Forgery

A forged will, or a will obtained by deceiving the testator about its contents, is invalid.

Improper Execution

If the will was not properly signed and witnessed (per Succession Act 1965 requirements), it is not a valid will.

Legal Right Share Claim

A spouse or civil partner can claim their legal right share (one-third with children, one-half without) regardless of what the will says. This is not a challenge to the will's validity — the will is accepted, but the legal right share is carved out first.

Section 117 — Child's Claim

Under Section 117 of the Succession Act, a child who feels the testator failed in their moral duty to make proper provision can apply to court. The court considers all circumstances and may award a portion of the estate. This must be brought within 12 months of the first taking out of representation (Grant of Probate or Letters of Administration).

How to Contest a Will

1. Act quickly — lodge a caveat at the Probate Office immediately to prevent probate proceeding
2. Instruct a Cork solicitor specialising in contested probate
3. Gather evidence — medical records, solicitor's file, witness statements, correspondence
4. Attempt mediation — many disputes settle before reaching the High Court
5. High Court proceedings if mediation fails

Time Limits

• Section 117 claims: 12 months from the first taking out of representation
• General challenges: Act quickly — caveats should be lodged as soon as you are aware of a death and a disputed will

Cost of Contesting a Will in Ireland

High Court litigation is expensive. A contested probate case can cost €50,000–€200,000+ in legal fees. Courts generally award costs against the losing party, but this is not guaranteed. Mediation and early settlement are strongly advisable.

Defending a Contested Will

If you are named in a will that is being challenged, or you are the executor of such a will, seek legal advice immediately. See: Contested Probate Cork.
