Cohabiting Couples and Inheritance Rights in Ireland (2026 Guide)
Last updated: April 2026
If you are living with your partner but are not married or in a civil partnership, Irish inheritance law treats you very differently. Many couples assume “common law marriage” gives automatic rights. In Ireland, it does not.
That means if one partner dies without a will, the surviving partner may inherit nothing, even after years together and shared finances.
Do Unmarried Partners Automatically Inherit in Ireland?
No. Under the Succession Act 1965, only spouses and civil partners have automatic inheritance protections like the legal right share. Cohabiting partners do not have that protection.
Without a valid will, your estate follows intestacy rules. Those rules prioritise spouse, children, parents, and blood relatives—not your unmarried partner.
What Rights Do Cohabiting Couples Have?
A surviving cohabiting partner may apply for provision under the Civil Partnership and Certain Rights and Obligations of Cohabitants Act 2010. But this is not automatic and can require legal action.
- You must usually qualify as a “qualified cohabitant.”
- You may need to prove financial dependence.
- The court has discretion and may award less than expected.
- Applications are time-sensitive and can be stressful during bereavement.
In short: relying on this route is risky. A will is the safer way to protect your partner.
Common Risk Scenarios for Cohabiting Couples
1) The Family Home Is in One Name
If the deceased owned the home solely and left no will, the survivor can face uncertainty, especially where other relatives inherit under intestacy.
2) Blended Families and Prior Relationships
Children from prior relationships may inherit by default while a current unmarried partner is left unprotected. Clear will planning is critical in blended-family estates.
3) Business or Farm Assets
Where assets are tied to family structures, a surviving partner can be squeezed out unless there is written planning.
How to Protect an Unmarried Partner in Ireland
- Make a valid Irish will naming your partner clearly.
- Appoint an executor who understands your wishes.
- Review beneficiary designations on pensions and life policies.
- Document ownership of major assets and contributions.
- Update your will after major life changes.

Cohabiting vs Married: Why the Difference Matters
Married and civil-partnered couples have strong automatic protections. Cohabiting couples must actively create those protections through estate planning documents.
That is why “we’ll sort it later” is one of the costliest mistakes in Irish will planning.
