Living Together but Not Married? The Legal Reality of Cohabitation in Ireland

The Need to Plan Ahead

Cohabitation is increasingly common in Ireland. However, cohabiting couples have significantly fewer legal protections than married couples or civil partners. While Irish law does recognise certain rights for long-term cohabitants, these rights are not automatic, particularly when it comes to succession and inheritance.

Understanding your legal position early and planning accordingly can help prevent serious financial and emotional hardship in the event of a relationship breakdown or on the death of a beloved partner.

Under Irish law, qualified cohabitants may make an application for redress following the breakdown of a relationship or the death of a partner. Such applications may seek financial support, property adjustment orders, pension adjustment orders, or a share in the assets of a deceased partner.

Who Is a Cohabitant Under Irish Law?

Cohabitation in Ireland is governed by the Civil Partnership and Certain Rights and Obligations of Cohabitants Act 2010 (the “2010 Act”). The Act provides a redress scheme for cohabitants on the breakdown of a relationship or on the death of a partner.

Under the 2010 Act, a cohabitant is defined as one of two adults who:

Live together in an intimate and committed relationship;
Are not married to each other or in a civil partnership; and
Are not related to one another.

When determining whether two people are cohabitants, the court will consider the following factors (section 172 of the 2010 Act):

The duration of the relationship;
The basis on which the couple live together;
The degree of financial dependence and any agreements relating to finances;
The nature of any financial arrangements, including joint purchases of real or personal property;
Whether there are dependent children;
Whether one adult cares for or supports the children of the other; and
The extent to which the couple present themselves as a couple to others.

Not all cohabitants qualify for legal protection under the Act. Only qualified cohabitants may seek redress.

To be deemed a qualified cohabitant, the applicant must have lived with their partner for:

Five years, or
Two years, where there are dependent children of the relationship.

Legal Rights on the Breakdown of a Relationship

Unlike married couples, cohabitants do not automatically share assets, regardless of the length of the length of time they have lived together. Importantly, any application for redress under the 2010 Act must be made within two years of the breakdown of the relationship. If this time limit is missed, the claim may be statute-barred. Different timelines apply where a cohabitant has died, as outlined below.

Key Points to Note

Property ownership generally depends on whose name appears on the title deeds or mortgage;
There is no automatic entitlement to maintenance or financial support;
Contributions to household expenses do not, by themselves, create a legal interest in property.

Where disputes arise, a qualified cohabitant may apply to the court for redress, which may include:

Property adjustment orders;
Maintenance orders; and
Pension adjustment orders.

These remedies are discretionary rather than guaranteed and will depend on the evidence presented, including the nature of the relationship and the level of financial dependence between the parties.

Where the parties have dependent children, issues such as guardianship, custody, access, and maintenance may also be addressed within the proceedings.

In deciding whether to make an order under the redress scheme, the court will consider the factors set out in section 173(3) of the 2010 Act, including:

The financial circumstances, needs, and obligations of each party;
The rights of any spouse, former spouse, civil partner, or former civil partner;
The needs and entitlements of any dependent children;
The duration and nature of the relationship and the level of commitment involved;
Financial and non-financial contributions made by each cohabitant, including contributions to the home;
The impact of the relationship on each party’s earning capacity;
Any physical or mental disability; and
Conduct, where it would be unjust to disregard it.

Financial Dependence

When applying to the court for redress following the breakdown of a relationship, the applicant must establish a degree of financial dependence on the other party. This may involve showing reliance on the other person for housing costs, living expenses, or other financial support.

For example, where one party paid the mortgage or rent on the shared home, this may indicate financial dependence. However, no single factor is determinative, and financial dependence is assessed on a case-by-case basis.

Cohabitants’ Agreements

Failing to prepare is preparing to fail. Couples may opt out of the redress scheme under the 2010 Act by entering into a Cohabitants’ Agreement while still in an intimate and committed relationship.

Such agreements are legally enforceable provided that:

Both parties receive independent legal advice;
The agreement is in writing; and
General contractual principles are complied with.

A Cohabitants’ Agreement allows couples who do not wish to marry to decide in advance what should happen if the relationship ends or if one partner dies. While these agreements are generally upheld, the court may set them aside in exceptional circumstances.

Succession Rights: What Happens When One Partner Dies?

“Unlike spouses or civil partners, cohabitants have no automatic right to inherit — even after many years together. Without a will, a surviving partner may be left with no legal entitlement at all.”

This is often the most misunderstood area of cohabitation law in Ireland and can have severe consequences. Unlike spouses or civil partners, cohabitants have no automatic right to inherit, regardless of the duration and nature of the relationship.

Where there is no will, a surviving cohabitant is not entitled to any share of the estate under the Succession Act 1965, even where there are children or significant financial dependence.

Applying for Provision from the Estate

Under section 194 of the 2010 Act, a qualified cohabitant may apply to the court for provision from a deceased partner’s estate. This application must be made within six months of the grant of representation.

If the relationship ended more than two years before the death, no application can be made. In cases involving the death of a cohabitant, financial dependence is less central than it is on relationship breakdown.

When deciding whether to make provision from the estate, the court will consider:

The factors listed in section 173(3) of the 2010 Act; (also listed above)
Whether financial orders were made during the deceased’s lifetime;
Whether the applicant was provided for in a valid will; and
The interests and needs of other beneficiaries.

The court may make provision where it is satisfied that proper provision was not made during the deceased’s lifetime. However, the award cannot exceed what a spouse would have received and may be significantly less.

Litigation in this area can be complex, stressful, and costly. Early legal advice is strongly recommended.

The Bereaved Partner’s Pension

The Bereaved Partner’s Pension is a weekly social welfare payment made to the partner of a deceased person. While it was previously limited to spouses and civil partners, from July 2025 it has been extended to include qualified cohabitants.

The payment is not means-tested and may be available provided:

The relationship had not broken down prior to death; and
Both parties satisfy the relevant PRSI contribution conditions.

Conclusion

While cohabitation offers flexibility and autonomy in personal relationships, Irish law continues to provide limited legal protection for cohabiting couples, particularly in circumstances involving relationship breakdown or death. Many people are surprised to learn how restricted their rights can be without marriage, a civil partnership, or appropriate legal planning.

Understanding your rights and the potential risks is essential. Early planning, including the preparation of a Cohabitants’ Agreement and a valid will, can significantly reduce uncertainty and protect both partners.

“Many cohabiting couples assume they have the same legal rights as married couples – but in Ireland, that is often not the case. Without proper planning, partners can be left financially vulnerable.”

If you are living with a partner, considering moving in together, or have concerns regarding property, succession, or financial security, seeking tailored legal advice can provide clarity, protection, and peace of mind.
