UK Citizen With Irish Assets: Cross-Border Estate Administration

How do I administer Irish assets as part of a UK estate?

1Ireland does not apply EU Succession Regulation 650/2012 — it opted out, as did the UK, so Irish private international law governs Irish assets
2An English Grant of Probate can be re-sealed in the Irish Probate Office without needing a separate Irish probate application for most estates
3Irish Capital Acquisitions Tax (CAT) may be payable on Irish assets inherited by UK-resident beneficiaries; the rate is 33% above the relevant threshold
4There is a UK–Ireland double taxation treaty covering inheritance taxes, preventing double taxation on the same assets
5Irish property must be transferred through an Irish solicitor; the Land Registry of Ireland handles registration

Administering Irish assets in a UK estate is more straightforward than most cross-border situations because an English Grant of Probate can usually be re-sealed in Ireland. However, Irish Capital Acquisitions Tax and the involvement of an Irish solicitor are still required.

Many UK citizens have connections to Ireland — through family, property ownership, or financial investments. When a UK citizen dies holding Irish assets, the estate administration requires both UK probate and Irish procedures, though the historical legal connections between England and Ireland mean the process is generally less complex than dealing with most other overseas jurisdictions.

This guide covers the re-sealing process, Irish CAT, the role of the Irish solicitor, the interaction with UK IHT, and common types of Irish assets UK citizens hold.

Re-Sealing an English Grant in Ireland

Under the Succession Act 1965 (Ireland) and historical Commonwealth arrangements, an English Grant of Probate (or Letters of Administration) can be re-sealed by the Irish Probate Office in Dublin. Re-sealing gives the grant legal effect in Ireland without requiring a separate Irish probate application.

The re-sealing process involves:

Obtaining the UK Grant of Probate — see our guide on applying for probate
Instructing an Irish solicitor to make the re-sealing application
Submitting the original or certified copy of the UK grant to the Irish Probate Office
Paying the Irish Probate Office fee (calculated on the value of Irish assets)
Receiving the re-sealed grant, which can then be used to deal with Irish banks, the Land Registry, and other Irish institutions

Re-sealing typically takes 4–8 weeks once the UK grant has been obtained. An Irish solicitor is essential for this process; see our guide on re-sealing a Commonwealth grant for more detail on the general procedure.

Note: If the deceased was domiciled in Ireland at death, an Irish grant is required as the primary grant. If domiciled in England and Wales, the English grant takes precedence and can be re-sealed in Ireland.

Irish Capital Acquisitions Tax (CAT)

Ireland levies Capital Acquisitions Tax (CAT) on gifts and inheritances. Unlike UK IHT, which is paid by the estate, Irish CAT is a tax on the beneficiary. The rate is 33% on the taxable value above the relevant group threshold.

The group thresholds (as at 2024) are:

Group A (children, and in certain cases grandchildren): €335,000 lifetime threshold
Group B (parents, siblings, nieces/nephews, grandchildren not in Group A): €32,500
Group C (all others): €16,250

These are lifetime thresholds — all gifts and inheritances received from persons in the same group aggregate over the beneficiary's lifetime. A UK beneficiary receiving Irish assets is subject to Irish CAT if either the disponer (deceased) was domiciled or resident in Ireland, or the property is Irish-situated property.

The UK–Ireland double taxation agreement on estates means that credit can be given for either UK IHT or Irish CAT against the other, preventing the same assets being taxed twice in full. The mechanics are complex; specialist advice should be taken on claiming the treaty credit correctly.

Irish CAT returns must be filed by the beneficiary by 31 October in the year following the valuation date (the date the inheritance became absolute). Late filing and payment attract interest and penalties.

Types of Irish Assets: What UK Citizens Commonly Hold

UK citizens with Irish connections may hold various types of Irish assets that need to be dealt with as part of the estate:

Irish property: Farmland, family homes, or investment properties. Transfer requires re-sealed grant and registration at the Land Registry of Ireland or the Registry of Deeds
Irish bank and building society accounts: Irish banks will generally require the re-sealed grant or a grant of administration in Ireland before releasing funds
Irish shares and securities: Irish Stock Exchange quoted shares and unquoted shares in Irish companies require the re-sealed grant for transfer
Irish pension entitlements: If the deceased was a member of an Irish pension scheme, the scheme trustees will have their own death benefit payment rules; these may pass outside the estate
Irish company interests: Interests in Irish-registered companies, partnerships, or farming businesses require specialist Irish legal and tax advice, particularly regarding Irish agricultural relief or business relief equivalents

Domicile and Its Importance for UK–Irish Estates

Domicile determines which country's succession laws apply to movable property (such as bank accounts and shares). For UK citizens who have spent significant time in Ireland or who were born in Ireland and moved to the UK, the question of domicile at death can be contested.

Key rules:

A person domiciled in England and Wales at death has their movable property governed by English succession law
Irish immovable property (land and buildings) is governed by Irish law regardless of domicile
If domicile is disputed between the UK and Ireland, legal proceedings in both countries may be needed to resolve it
Deemed domicile rules for UK IHT (15 of 20 years UK resident) are independent of the common law domicile concept used for succession purposes

For more on domicile and its tax implications, see our guide on IHT for non-UK domiciles.
