How inheritance laws work in Ireland

If you own property or assets in Ireland, understanding Irish inheritance laws can save your family unnecessary stress, delays and tax bills later on. Putting the right legal arrangements in place now helps ensure your wishes are followed and your loved ones are protected.

Buying a home in Ireland often starts with excitement about a new lifestyle, retirement plans or a fresh start overseas. Yet many overseas buyers overlook one of the most important parts of long-term planning – what happens to your Irish assets when you die. Irish succession rules can affect everything from property ownership to inheritance tax liabilities, particularly if you have family living outside Ireland.

Making a valid Irish will and understanding how Capital Acquisitions Tax works could make a significant difference to your family’s financial future. Here’s what you need to know about inheritance laws in Ireland in 2026.

Why Irish inheritance laws matter for overseas buyers

If you own property, savings or investments in Ireland, Irish succession law may apply to those assets, even if you permanently live elsewhere. Without an Irish will, your estate will usually be treated as intestate, meaning the Succession Act 1965 determines who inherits your assets.

That can create delays, legal costs and disputes at an already difficult time for your family. It may also mean your estate is distributed differently from your intentions.

Creating a separate Irish will covering your Irish assets can help streamline probate and reduce complications for beneficiaries living abroad. Many solicitors recommend this approach for overseas property owners, especially if you already have a will in another country.

What happens if you die without a will in Ireland

Under Irish inheritance laws, the rules of intestacy decide how your estate is divided if no valid will exists.

Your family situation	How the estate is divided	Key point
Married or in a civil partnership with no children	Spouse or civil partner inherits everything	Children from previous relationships may not inherit automatically
Married with children	Spouse receives two-thirds and children share one-third equally	Children inherit automatically under intestacy rules
Single with children	Children inherit the estate equally	Grandchildren may inherit if a child has already died
Single with no children	Parents inherit first, then siblings if parents are deceased	More distant relatives may inherit if no close family exists
No identifiable relatives	Estate may pass to the State	The Probate Office attempts to identify next of kin first

Even if these arrangements broadly match your wishes, a professionally drafted will can reduce uncertainty and help avoid disagreements between family members.

Legal rights of spouses and children in Ireland

Irish succession law gives spouses and civil partners strong legal protections. Even if a will excludes them, they are generally entitled to a fixed share of the estate called a legal right share.

Children do not have an automatic fixed entitlement under Irish law. However, under Section 117 of the Succession Act, a child can apply to court if they believe a parent failed in their moral duty to make proper provision for them.

Courts consider factors such as:

• The size of the estate
• The child’s financial position
• Any special medical or care needs
• Contributions made by the child to the deceased’s welfare or business
• Promises or expectations created during the parent’s lifetime

Irish courts have become more cautious about adult children bringing inheritance claims in recent years. Judges increasingly focus on whether genuine financial need exists rather than assuming children should automatically inherit substantial assets.

Capital Acquisitions Tax in Ireland

Beneficiaries receiving gifts or inheritances in Ireland may have to pay Capital Acquisitions Tax (CAT). The tax applies to amounts above specific lifetime tax-free thresholds.

As of 2026, CAT is charged at 33% on the value above the relevant threshold.

Relationship group	Examples	2026 tax-free threshold
Group A	Children, adopted children, certain foster children	€400,000
Group B	Brothers, sisters, nieces, nephews, grandchildren	€40,000
Group C	All other beneficiaries	€20,000

Thresholds can change during government budgets, so it is worth reviewing inheritance planning regularly.

Irish inheritance tax exemptions

Several exemptions may reduce or eliminate inheritance tax liability in Ireland.

These include:

• Transfers between spouses or civil partners
• Certain compensation or damages payments
• Approved pension benefits
• Some charitable inheritances
• Lottery and gambling winnings
• Agricultural and business reliefs in qualifying cases

You may also qualify for Dwelling House Relief if you inherit a property that has been your main residence for a continuous period before the inheritance and you meet Revenue’s conditions.

Because Irish tax law can become complex for overseas residents, cross-border legal and financial advice is essential before making major decisions.

Why overseas owners should consider an Irish will

If you already have a will in the UK or another country, that may not be enough to simplify matters in Ireland. Probate can become slower and more expensive when multiple jurisdictions are involved.

An Irish solicitor can help ensure:

• Your Irish property passes according to your wishes
• Probate is handled more efficiently
• Your executor can deal with Irish banks and authorities
• Potential tax liabilities are reduced where possible
• Your overseas will and Irish will work together correctly

It is important that multiple wills are drafted carefully to avoid one accidentally revoking the other.

Common inheritance mistakes overseas buyers make

Many overseas buyers unintentionally create problems for their families by delaying inheritance planning.

Some of the most common mistakes include:

• Assuming a foreign will automatically covers Irish assets properly
• Forgetting to update wills after remarriage or divorce
• Leaving property jointly without understanding survivorship rules
• Ignoring inheritance tax exposure for children living abroad
• Failing to document gifts or loans made during their lifetime

Reviewing your estate plan every few years is sensible, particularly after major life changes or property purchases.

Final thoughts on Irish inheritance laws

Thinking about inheritance planning may not feel urgent when you are settling into life in Ireland, but dealing with it early can save your family considerable stress later. Irish succession and tax laws contain several quirks that overseas owners often overlook until it is too late.

A properly structured Irish will, combined with professional legal and financial advice, can help ensure your property and savings are passed on smoothly and tax-efficiently.
