Can I get a marriage annulment in Ireland?
Only in defined situations — a civil decree of nullity declares that, in law, the marriage never existed. A marriage can be void (treated as never having existed — you don't strictly need a decree, but it's wise for certainty) or voidable (valid until a court grants the decree). Grounds for a void marriage include one party already being married, the parties being within prohibited degrees of relationship, a lack of valid consent (duress or mental incapacity), or non-observance of formalities. Grounds for a voidable marriage include impotence or an inability to sustain a normal marital relationship at the time of the ceremony. Applications go to the Circuit or High Court. Crucially, a church (Catholic) annulment has no legal effect — you'd still be legally married. In short: conditional — only on specific legal grounds, through the courts.
📋 The rules
- A decree of nullity says the marriage never existed
- Void: treated as never valid (e.g. already married)
- Voidable: valid until a court grants the decree
- Applications go to the Circuit or High Court
- A church annulment has no legal effect
🔓 Exceptions
- Void grounds: prior marriage, prohibited relationship, no valid consent
- Voidable grounds: impotence or inability to sustain a normal marriage
- After a decree, you were never a 'spouse' — no spousal property/pension rights
⚠️ Penalties & fines
There are no fines, but the consequences are significant: an annulled marriage means both parties lose any rights they held as spouses — succession, maintenance, pension — and children's status and maintenance are dealt with separately. Unlike divorce, there's no division of property or pension as a spouse, because in law you were never married. There's no fixed statutory fee scale like divorce — legal costs are the main expense. Beware a myth: "a church annulment lets me remarry" is false — it only allows remarriage in the eyes of the church; to remarry legally you need a civil decree of nullity or a divorce. To pursue one: get legal advice on whether your circumstances meet the void or voidable grounds, as nullity is harder to obtain than divorce.

❓ Frequently asked
What is a decree of nullity?
A decree of nullity, or civil annulment, is a court declaration that a marriage never legally existed. It's different from a divorce, which ends a valid marriage. A marriage can be void — treated as never valid — or voidable, meaning valid until the court grants the decree, after which it's treated as never having existed.
On what grounds can I get an annulment?
Grounds for a void marriage include one party already being married, the parties being too closely related, a lack of valid consent such as duress or mental incapacity, or failure to observe the legal formalities. Grounds for a voidable marriage include impotence, or an inability to sustain a normal marital relationship at the time of the ceremony.
Is a church annulment the same thing?
No. A church annulment, such as a Catholic annulment, has no legal effect in the State. Even if you obtain one, you remain legally married and can't remarry in a civil ceremony on the strength of it. To remarry legally, you need either a civil decree of nullity or a divorce.
How is annulment different from divorce?
With divorce, a valid marriage is legally ended, and property, maintenance and pensions are divided between spouses. With an annulment, the court declares the marriage never legally existed, so neither party was ever a spouse and there are no spousal property or pension rights to divide. Annulment is also generally harder to obtain.
Do I need a court for an annulment?
Yes. A civil annulment is granted by the Circuit Court or High Court on specific legal grounds — you can't get one administratively. For a void marriage you may not strictly need a decree, but obtaining one provides legal certainty. Because the grounds are narrow and technical, legal advice is strongly recommended.
