How to Update Your Will in Ireland: When and Why

Creating a will is a crucial step in protecting your family's future, but it's not a once-and-done task. Your will is a living document that should evolve as your life changes. In Ireland, major life events can significantly affect how your estate is distributed—sometimes in ways you never intended.

This guide explains exactly when you should update your will, the legal requirements for making changes in Ireland, and the common mistakes that could invalidate your wishes.

When Should You Update Your Will in Ireland?

Life doesn't stand still, and neither should your will. Several key life events trigger an urgent need to review and update your testamentary wishes.

Marriage or Remarriage

Under Irish law, getting married automatically revokes any will you made before the marriage—unless the will was specifically made "in contemplation of marriage" to that particular person. This is one of the most misunderstood aspects of Irish succession law.

If you marry and don't create a new will, you'll die intestate (without a valid will), and your estate will be distributed according to the Succession Act 1965. This means:

• Your spouse receives two-thirds of your estate if you have children, or the entire estate if you don't
• Your children share the remaining one-third equally if you have both a spouse and children
• Any specific bequests you'd planned (to siblings, charities, or friends) will be ignored

Action required: Make a new will as soon as possible after marriage. If you're planning to marry, consider making a will "in contemplation of marriage" that specifically names your intended spouse—this will remain valid after the wedding.

Separation, Divorce, or Dissolution of Civil Partnership

Unlike marriage, divorce does not automatically revoke your will in Ireland. However, it changes the legal landscape significantly:

• Your divorced spouse loses their automatic right to a legal right share of your estate
• Any gift you left to your ex-spouse in your will remains valid unless you update it
• If your ex-spouse was named as executor, they can still serve in that role unless removed

Separation (judicial separation or deed of separation) doesn't affect your will's validity, but your spouse may still have succession rights depending on your separation agreement.

Action required: Update your will immediately after divorce or separation. Remove your ex-spouse as beneficiary and executor, appoint new guardians for minor children if needed, and ensure your estate goes where you intend.

Birth or Adoption of Children

Having a child—whether biological or adopted—doesn't invalidate your will in Ireland, but it creates a dangerous gap. If your will doesn't mention a child who was born or adopted after you made it, that child could be considered "inadvertently disinherited."

Under Section 117 of the Succession Act 1965, children can apply to court if they believe the will has "failed in its moral duty to make proper provision" for them. A child not mentioned in the will has strong grounds for such a claim.

Action required: Update your will within months of a child's birth or adoption. Include:

• The child's name and share of your estate
• Guardianship provisions if they're under 18
• Trust arrangements if you want assets held until they reach a certain age
• A clause covering "future children" if you plan to have more

Significant Property or Asset Changes

Major changes to what you own can make your will outdated or create confusion:

• Buying or selling property: If your will leaves "my house at 123 Main Street" to someone, but you've since sold that house and bought another, the gift fails. The beneficiary gets nothing.
• Selling a business: If you've bequeathed a business that no longer exists, that gift lapses
• Large inheritance or windfall: Receiving substantial assets may change how you want to distribute your estate
• Significant debt: New mortgages or liabilities affect what's available to distribute

Action required: Review your will whenever you buy or sell significant assets. Instead of leaving specific properties, consider percentage-based distributions ("50% of my estate to my daughter") which adapt automatically to asset changes.

Death of a Beneficiary or Executor

If someone named in your will dies before you, Irish law has default rules—but they may not match your wishes:

• If a beneficiary dies before you, their gift usually lapses and falls into the residue of your estate—unless they're your child, in which case their children (your grandchildren) typically inherit their share
• If your sole executor dies, you'll need to appoint a replacement or the court may need to appoint an administrator
• If a guardian dies, your children could be without your chosen protection

Action required: Update your will to name replacement beneficiaries and alternate executors. Many people include "substitute gift" clauses that specify what happens if a primary beneficiary predeceases them.

Changes in Relationships

Family dynamics shift over time. You may want to update your will if:

• You've become estranged from a family member originally included
• A new grandchild is born
• You want to include a partner you're not married to
• Your relationship with siblings or parents has changed
• You want to add or remove charitable donations

Action required: While there's no legal requirement to update for relationship changes, doing so ensures your will reflects your current wishes—not outdated obligations.

Moving to or from Ireland

If you relocate internationally, both your previous country and Ireland may have claims on different parts of your estate. Irish law governs succession to property located in Ireland and can affect how foreign wills are recognised.

Action required: Seek legal advice if moving countries. You may need separate wills for assets in different jurisdictions.

How to Update Your Will in Ireland: Two Legal Methods

Once you've decided your will needs updating, Irish law gives you two options: create an entirely new will, or add a codicil to your existing will.

Making a New Will

The simplest and clearest approach is to create a completely new will that revokes all previous wills. This is the recommended option for:

• Major life changes (marriage, divorce, new children)
• Substantial changes to beneficiaries or executors
• Complete restructuring of how you want your estate distributed
• When your existing will is more than 5-10 years old

Legal requirements for a new will in Ireland:

1. You must be at least 18 years old (or married/in civil partnership)
2. You must have mental capacity to understand what you're doing
3. The will must be in writing
4. You must sign the will at the end, in the presence of two witnesses
5. Both witnesses must sign in your presence and in each other's presence
6. Witnesses cannot be beneficiaries or married to beneficiaries
7. Include a revocation clause: "I revoke all former wills and testamentary dispositions"

Once you've executed your new will, destroy all copies of your old will to avoid confusion. Don't just store them together—physically destroy previous versions.

Adding a Codicil

A codicil is a formal legal amendment to an existing will. Think of it as an official update that doesn't replace the entire document. Codicils are suitable for:

• Minor changes (updating an address, changing a small cash gift)
• Appointing a substitute executor
• Adding a small bequest
• Correcting an error or clarifying ambiguous language

Legal requirements for a codicil in Ireland:

A codicil must meet the exact same formal requirements as a will:

• Must be in writing
• Must be signed by you at the end
• Must be witnessed by two independent witnesses who sign in your presence
• Must clearly reference the will it's amending ("This is the first codicil to my will dated [date]")

Store your codicil with your original will so both documents are found together when needed.

New Will vs Codicil: Which Should You Choose?

In most cases, making a new will is simpler, clearer, and less prone to confusion. Here's why:

• Clarity: A single document is easier for executors and family to understand
• Reduced risk: Multiple codicils can create conflicting instructions
• Cost: With online will services like MakeAWill.ie, creating a new will costs the same as drafting a codicil
• Comprehensiveness: You can review everything in one go rather than patching individual items

Use a codicil only for truly minor, straightforward changes. For anything significant, make a fresh start.

Legal Requirements: What Makes an Update Valid?

Whether you're making a new will or a codicil, these requirements are non-negotiable under Irish law:

Proper Execution

• Your signature: Must be at the end of the document. Any text below your signature may be disregarded.
• Two witnesses: Must see you sign (or acknowledge your signature) and must sign in your presence and each other's presence
• Witness independence: Cannot be beneficiaries or their spouses—if they are, they lose their inheritance
• Mental capacity: You must understand the nature of making a will, the extent of your property, and who might reasonably expect to benefit

No Undue Influence or Fraud

Your will can be challenged if someone proves you were:

• Pressured or coerced into changing your will
• Deceived about the contents of the document you signed
• Not acting of your own free will

To protect against this, make updates when you're healthy and thinking clearly, and consider having your solicitor or GP confirm your capacity if there's any possibility of a challenge.

Common Mistakes When Updating Your Will

These errors can invalidate your update or create expensive legal battles for your family:

1. Making Handwritten Changes to an Existing Will

Crossing out names, adding notes in the margin, or changing amounts by hand does not legally update your will in Ireland. These alterations are usually ignored, and the original typed text stands—or worse, the entire will could be challenged as tampered with.

Solution: Never mark up your will. Make a new will or formal codicil instead.

2. Unsigned or Improperly Witnessed Updates

Forgetting to sign in front of witnesses, or having only one witness, makes your update legally worthless. Both witnesses must be present when you sign, and they must sign in your presence.

Solution: Follow the execution requirements exactly. Gather your two witnesses, explain what you need (without revealing the contents), and have everyone sign in the right order.

3. Using Beneficiaries as Witnesses

If a beneficiary or their spouse witnesses your will or codicil, they automatically lose their entitlement to any gift under that will. This is an absolute rule under Section 82 of the Succession Act 1965.

Solution: Choose completely independent witnesses—neighbours, colleagues, or friends who have nothing to gain from your will.

4. Forgetting to Revoke Previous Wills

If you make a new will but don't include a revocation clause, you could end up with multiple "valid" wills that conflict with each other. This creates probate nightmares.

Solution: Always start your new will with: "I revoke all former wills and testamentary dispositions made by me."

5. Not Destroying Old Wills

Even if you've revoked an old will in writing, keeping it around can cause confusion. Family members may find the old version first and not realise it's been superseded.

Solution: Once your new will is properly executed, physically destroy all copies of previous wills.

6. Delaying the Update

The biggest mistake is knowing you need to update your will but putting it off. Life is unpredictable—you can't control when you'll die, but you can control whether your will is current.

Solution: Set a deadline. If a major life event has occurred, update your will within 30 days. If nothing major has changed, review your will every 3-5 years.

7. Not Considering Digital Assets

Modern estates include cryptocurrency, online business accounts, social media, photo libraries, and domain names. Many people update their wills for property and cash but forget these valuable digital assets.

Solution: Include provisions for digital executors and clear instructions for accessing and distributing digital property.

How Often Should You Review Your Will?

General rule of thumb: review your will every 3-5 years, and immediately after any major life event.

Set a recurring calendar reminder for the anniversary of making your will. During each review, ask:

• Are all named people still alive?
• Have my assets changed significantly?
• Are my executors and guardians still appropriate?
• Do my beneficiaries reflect my current wishes?
• Have laws changed that affect my estate plan?

If you answer "no" to any of these, it's time for an update.

The Cost of Not Updating Your Will

Failing to keep your will current can result in:

• Unintended beneficiaries: Your ex-spouse receiving assets meant for your new partner
• Excluded children: A child born after your will was made having to fight for their share in court
• Failed gifts: Property you no longer own being left to someone, who gets nothing instead
• Wrong guardians: Children raised by someone you'd never choose today
• Family conflict: Ambiguity and outdated wishes leading to expensive court battles
• Intestacy: Your entire will being invalid, with the state deciding who gets what

The few hours it takes to update your will can save your family months of legal proceedings and thousands in legal fees.

Final Thoughts

Your will is one of the most important documents you'll ever create—but only if it's current. Life changes constantly, and your will should change with it. Marriage, children, divorce, new property, and the death of loved ones all demand immediate updates.

The legal requirements for updating your will in Ireland are straightforward: make a new will with proper execution formalities, or add a codicil for minor changes. The real challenge is simply taking action.

Don't wait for a crisis. Review your will today, and if it needs updating, make it a priority this week—not next month, not next year. Your family deserves the clarity and protection that only a current, legally valid will can provide.
