How to Properly Sign Your Will in Ireland

Quick answer · Applies to Ireland
Sign your will at the end of the document, in pen, in front of two witnesses who are both present at the same moment. Both witnesses then sign. Do not sign before they arrive, and do not use a beneficiary as a witness.
Signing your will correctly is one of the most important steps in making it legally valid. In Ireland, the rules around signing are set out in the Succession Act 1965.
If the signing process isn't followed properly, your entire will could be challenged or declared invalid — even if the content is perfectly clear.
The Basic Rule
Under Section 78 of the Succession Act 1965, a will must be:
- In writing
- Signed at the foot or end by the testator (the person making the will), or by someone in their presence and at their direction
- The signature must be made or acknowledged in the presence of two witnesses
- Both witnesses must then sign the will in the presence of the testator
Where Should You Sign?
Your signature should appear at the very end of the will, after all clauses and instructions. Anything written below the signature may not be legally valid.
If multiple pages are involved, it is good practice (though not strictly required by law) to initial each page.
Can Someone Else Sign on Your Behalf?
Yes, if you are physically unable to sign, another person may sign the will on your behalf — provided they do so in your presence and under your direction. This must still be witnessed by two people.
Who Can Be a Witness?
A witness must be over 18 and of sound mind. Importantly, a witness (or their spouse) should not be a beneficiary under the will. If a beneficiary witnesses the will, they may lose their entitlement under Section 82 of the Succession Act.
What Happens If the Will Isn't Signed Properly?
If the signing requirements are not met, the will may be deemed invalid. This could mean:
- Your estate is distributed under intestacy rules instead of your wishes
- Beneficiaries you intended to provide for may receive nothing
- Family disputes may arise over the estate
Tips for a Smooth Signing
- Use a pen with permanent ink (blue or black)
- Sign in the presence of both witnesses at the same time
- Make sure witnesses are not beneficiaries
- Do not make any changes to the will after signing — if changes are needed, consider a codicil or a new will
- Keep the original signed will in a safe place
Summary
Signing your will is not just a formality — it is a legal requirement. Taking a few minutes to get it right can prevent serious problems down the line.
