Irish Nationals Inheriting in Spain: CAT, EU Succession Regulation and Practical Steps from Dublin
Ireland is bound by EU Regulation 650/2012 in the same way as Spain, although the regulation is implemented in Ireland in a slightly different procedural form than in continental civil-law countries. For Irish families with a holiday home in Marbella, Alicante or the Balearics, this means the choice of Irish law in a Spanish will is available and effective, and the European Certificate of Succession (CSE) issued in Ireland is recognised in Spain without further legalisation. The Irish capital acquisitions tax (CAT) operates differently from inheritance tax in the UK or Germany — it is levied on the beneficiary rather than on the estate — and the Irish-Spanish tax credit mechanism for CAT against Spanish inheritance tax requires careful handling. This article explains the procedural mechanics of an Irish-Spanish inheritance, including the role of the Irish solicitor in obtaining the Irish grant of probate (where relevant) or the European Certificate of Succession, the calculation of CAT and its credit against Spanish tax, and the practical steps for heirs in Dublin, Cork, Galway and Limerick. A dedicated inheritance lawyer in Spain coordinates with the Irish solicitor and the Irish tax adviser.
Irish succession law and the EU regulation
Ireland is one of the few EU member states with a common-law succession system. The Succession Act 1965 governs Irish succession and includes a legal-right share for spouses (one third of the estate if there are children, half if there are no children) and a more limited protection for children (no automatic entitlement, but a power for the court to make provision under section 117). The Irish system is therefore less rigid than the Spanish legítima and gives the testator substantial freedom of disposition.
Ireland is bound by EU Regulation 650/2012 (Ireland did opt into the regulation, unlike the UK and Denmark). The choice of Irish law in a Spanish will is therefore available to Irish nationals and is fully effective. The Irish testator who chooses Irish law in a Spanish will has the estate governed by Irish succession rules, with the legal-right share for the spouse but no automatic forced share for the children. The choice mechanism and the underlying framework are explained in our overview of the EU Succession Regulation.
The European Certificate of Succession in Ireland
The CSE is issued in Ireland by the Probate Office of the High Court (in Dublin) on application by the personal representative of the deceased. The application is made by the solicitor and is usually processed within four to six weeks of submission. The CSE is recognised automatically in Spain without further legalisation, and is the standard document used to evidence the heirs’ status in a Spain-Ireland inheritance file.
For Irish estates without a will (intestate estates), the procedure is more complex because the personal representative must first be appointed by the Irish court before the CSE can be issued. The appointment of an administrator in an Irish intestacy can take three to six months. For Spain-Ireland intestacies with a tight Spanish six-month deadline, the Spanish file is usually started in parallel — with the heirs identified by reference to the Irish intestacy rules and an interim Spanish-side power of attorney granted by all the heirs — and the CSE is used later for property registration once it issues.
Capital Acquisitions Tax (CAT) and the foreign-tax credit
Ireland levies Capital Acquisitions Tax (CAT) on the beneficiary of an inheritance at a flat rate of 33% on the amount above the relevant tax-free threshold. The thresholds are: Group A (parent to child) approximately €335,000 per child over a lifetime; Group B (other close relatives) approximately €32,500; Group C (everyone else) approximately €16,250. The thresholds are cumulative — gifts and inheritances received from the same group during the lifetime are aggregated against a single threshold. CAT is filed by the beneficiary on Form IT38, with a self-assessment deadline of 31 October in the year following the inheritance.
Spanish inheritance tax paid by an Irish-resident beneficiary on the Spanish-situs portion of an inheritance is creditable against the Irish CAT on the same property under the Spain-Ireland double tax convention (1994) and under Irish unilateral relief in CATCA 2003 section 107. The credit is per-asset and capped at the Irish CAT attributable to that asset. For most Spain-Ireland files, the Andalusian or other regional reductions reduce the Spanish tax to near zero for direct descendants, and the Irish CAT is the binding tax cost. The Spanish proof of payment is required to support the Irish credit claim.
The Spanish notarial deed and Irish probate documents
Spanish notaries accept the European Certificate of Succession directly. They also accept an apostilled and sworn-translated Irish grant of probate (or letters of administration) where a CSE has not been issued. The Irish solicitor provides whichever document is appropriate, and the Spanish lawyer uses it as the basis for the deed of acceptance. The deed of acceptance is signed by all the heirs (or by their representatives under a power of attorney) before a Spanish notary, and is the primary title document for the Spanish-side property registration.
A practical point: Irish wills are sometimes drafted to give the executor authority to sell the estate’s real property as part of the administration. This authority is recognised in Spain through the CSE or the Irish grant of probate, but the Spanish-side sale must follow the Spanish notarial procedure (sale deed before a Spanish notary, IRNR retention, Land Registry update). The Irish authorisation alone is not sufficient to complete a Spanish sale; the Spanish procedural steps must also be followed.
Heirs in Dublin and elsewhere in Ireland
Dublin-based heirs have ready access to Irish solicitors with cross-border inheritance experience and to the Spanish embassy in Dublin for any consular requirements. The Spanish embassy can issue powers of attorney directly in Spanish, and appointment availability in Dublin is usually two to four weeks. For heirs in Cork, Galway, Limerick and other Irish cities, the procedure is the same, with appointments at the Spanish embassy in Dublin or, alternatively, at a local Irish notary with subsequent apostille by the Department of Foreign Affairs. The cost and timing are comparable. Country-specific guidance is available in our article on Irish nationals inheriting in Spain.
The Irish solicitor in Dublin typically retains overall responsibility for the Irish-side estate administration (probate, CAT filing, Irish bank account closures) and works with the Spanish lawyer on the Spanish-side acts (deed of acceptance, inheritance tax filing, Land Registry registration). The two professionals communicate by email and exchange documents as needed. The heirs’ direct involvement is limited to providing the necessary signatures and documents on the Spanish side.
Spanish bank accounts and the Irish reporting regime
Ireland is a participant in the Common Reporting Standard and receives automatic information on Spanish bank accounts held by Irish-resident persons. An Irish-resident heir who inherits a Spanish bank account must declare it in the Irish tax return for the year of inheritance and every subsequent year while it remains open. The Spanish bank reports the account to the Irish Revenue, which cross-references with the heir’s declarations. Failure to declare results in queries and potentially penalties.
For Irish-resident heirs of Spanish real estate, the property is part of the heirs’ Irish capital gains tax (CGT) base when later sold. The Irish CGT acquisition cost is the fair market value on the date of the deceased’s death (the same step-up basis that applies for Spanish purposes). Any subsequent gain is taxed in Ireland at 33% with credit for Spanish CGT paid on the same gain under the Spain-Ireland double tax convention. The credit is per-gain and capped at the Irish CGT attributable to the Spanish-source gain.
Practical steps for an Irish family in the first month
Day one to five: instruct the Irish solicitor and engage a Spanish lawyer. Day five to fifteen: arrange for the Irish grant of probate application or, preferably, the CSE application. Day fifteen onward: prepare the Spanish power of attorney for each heir (if the executor route is not being used) or for the executor (if it is), arrange for the signature in Dublin (Spanish embassy or local notary with apostille), and request the heirs’ NIE numbers in parallel. The full timeline to completion is typically four to six months from instruction, in line with the Spanish six-month tax deadline.
The single most important early decision is whether the file will be handled through the executor under the CSE (simpler and faster) or through individual powers of attorney from each heir (more flexible but more cumbersome). For most Irish estates the executor route is preferable, and the CSE should be requested as soon as the Irish probate is granted. To start an Irish-Spanish inheritance file, contact our team.
Preventive planning for Irish nationals owning Spanish property
For Irish nationals who own Spanish property and are still alive, the planning steps are straightforward: make a Spanish will that disposes of the Spanish assets and expressly chooses Irish law under article 22 of the EU Succession Regulation; coordinate the Spanish will with the existing Irish will to ensure that the two do not unintentionally revoke each other; review the wills every five to ten years to reflect changes in family circumstances. The cost is a single notarial appointment in Spain (typically €60 to €100) and the protection is substantial.
A more sophisticated planning step, used by larger Irish-Spanish families, is to consider lifetime gifts to the next generation to use the Irish CAT thresholds gradually rather than in a single inheritance event at death. Lifetime gifts of property in Spain trigger Spanish gift tax (which is the same scale as inheritance tax and benefits from the same regional reductions) and Irish CAT (subject to the same threshold and rate as the inheritance). The structuring of lifetime gifts is more technical than will-drafting and should be done with advice from both Spanish and Irish advisers.
