Family Law in Ireland: Divorce, Separation, Cohabitants and Names

Family law in Ireland is really three separate systems that only sometimes overlap. A married couple has a staged path out of a marriage: a private separation agreement, then optionally judicial separation, then divorce, each with its own grounds and its own court. A cohabiting couple who never married has no equivalent status at all; Ireland has no common law marriage, so unmarried partners rely on a narrower statutory redress scheme instead of automatic spousal rights. Changing your name is a wholly separate legal act, common law use or a deed poll, that has nothing to do with a marriage or its ending, except that many people do it around the same time as one.

The single fact that decides most of what applies to a couple is whether they are married. Marriage brings court jurisdiction over separation and divorce, a right to have proper provision made, and exemption from tax on transfers between spouses. Cohabitation brings none of that automatically. A cohabitant has to prove they meet a minimum relationship length and financial dependency before a court will make any order at all, and a spouse, even an estranged one, always outranks a cohabitant's claim.

For separating or divorcing couples, timing is the second decisive fact. The living apart clock for both judicial separation and divorce changed on 1 December 2019, when the Family Law Act 2019 replaced the older thresholds following the 2019 constitutional referendum. Getting the current version of these Acts right matters, because the pre-2019 rules are still widely repeated online and no longer apply.

Jurisdiction scope: This hub covers family law in the Republic of Ireland: separation agreements, judicial separation, divorce, the cohabitants' redress scheme, and changing your name by deed poll. It does not cover Northern Ireland, the United Kingdom, or any other jurisdiction, and it does not cover child custody or maintenance in detail. It is general information, not advice for your situation.

Ending a marriage: separation agreements, judicial separation and divorce

Most marriage breakdowns in Ireland do not start in court. A separation agreement is a deed of separation, a legally binding written contract rather than a court order, and it settles matters like maintenance, the family home and children without either spouse going near a judge. It does not end the marriage itself, so neither spouse can remarry on the strength of it alone.

If a separation agreement is not available or is not enough, judicial separation is the court route that stops short of divorce. Since 1 December 2019 there are five grounds, not six: the Family Law Act 2019 deleted one of the original six grounds in the Judicial Separation and Family Law Reform Act 1989 and removed the requirement that a respondent consent to a separation based on four years' living apart. A separation agreement can also be turned into an order of court under section 8 of the Family Law (Maintenance of Spouses and Children) Act 1976, provided the court is satisfied the agreement is fair and reasonable and adequately protects both spouses and any dependent children.

Divorce is the only route that actually ends a marriage and allows remarriage, covered in the divorce guide. Since 1 December 2019 the spouses must have lived apart for at least two of the previous three years before applying, a figure set by the Family Law Act 2019 substituting section 5(1)(a) of the Family Law (Divorce) Act 1996. It is worth being precise about what changed and when: the 2019 referendum, the Thirty-eighth Amendment, removed the older four in five year rule from the Constitution itself, and the Family Law Act 2019 then set the current two in three year rule by ordinary statute six months later. Spouses can also count time living apart while still under the same roof, as long as they are not living together as a couple in an intimate and committed relationship. Divorce applications go to the Circuit Family Court, moving to the High Court only where the land involved is worth more than €3,000,000 and an interested party applies to transfer it, and there is no Courts Service fee for either a separation or a divorce application.

Whichever of the three routes a couple uses, a solicitor acting for either spouse in judicial separation or divorce proceedings has a specific statutory duty to discuss reconciliation and mediation, evidenced in practice by a signed form. Section 14(4) of the Mediation Act 2017 actually removes divorce and judicial separation from that Act's general mediation duty, so the real obligation sits in the older Family Law (Divorce) Act 1996 and the 1989 Act instead. The Family Mediation Service, run by the Legal Aid Board, is free and usually runs to three to six sessions, though waiting lists can apply.

Cohabiting couples: rights without marriage

Ireland has no common law marriage, so living together for any length of time does not, by itself, create the rights a spouse has. The cohabiting couples guide covers the redress scheme created instead, under the Civil Partnership and Certain Rights and Obligations of Cohabitants Act 2010.

To even qualify, section 172(5) of the 2010 Act requires the couple to have lived together as a couple for at least five years immediately before the relationship ended, or at least two years if they are the parents of a dependent child together. On top of that, the person applying has to show they are financially dependent on the other cohabitant because of the relationship or how it ended; qualifying alone does not entitle anyone to an order automatically. Section 173(5) also means a spouse the other cohabitant is or was married to always outranks the cohabitant's claim, and section 172(6) disqualifies a claim entirely if the other cohabitant was married to someone else and that spouse had not lived apart from them for four of the previous five years by the time the relationship ended, though that four in five test itself now only applies where the relationship ended before 1 December 2019.

An application for redress generally has to be made within two years of the relationship ending under section 195, though that limit does not apply to variation applications or to a claim against a deceased cohabitant's estate, which instead runs six months from the grant of representation under section 194. Couples can also contract out of the whole scheme in advance using a cohabitants' agreement under section 202. On death, Ireland's tax system still treats cohabitants as strangers to each other: gifts and inheritances above the Group C threshold of €20,000 are taxed at 33%, where transfers between spouses and civil partners are exempt from Capital Acquisitions Tax altogether.

Changing your name

Changing your name in Ireland is not a family law proceeding, and it works the same way whether or not a marriage or relationship is involved. The deed poll guide sets out the common law route, simply using a new name consistently, and the formal one, a Change of Name Deed Poll, which costs €60 in stamp duty, or €80 in total for a child's deed poll. Enrolling it in the Central Office of the High Court has never been required, though some institutions only accept an enrolled deed poll from the public Deed Poll Register.

This is where the routes above actually meet. Someone who separates or divorces and wants to revert to a pre-marriage name does not need a deed poll at all. According to Citizens Information, the Passport Service instead asks for the previous passport, birth certificate, marriage certificate and a certified separation or divorce document through Passport Online, falling back on proof of two years' use of the pre-marriage name only where those documents cannot be produced. A deed poll also never changes a birth certificate itself, and changing a child's name needs the consent of both parents, with a court able to dispense with a refusing parent's consent.
