Convert civil partnership to marriage and marriage to civil partnership

Converting your relationship

You can convert your same sex civil partnership to a marriage if:

• you formed a civil partnership in Northern Ireland
• you formed a civil partnership abroad at a consular or embassy under the Civil Partnership (Registration Abroad and Certificates) Order 2005

or

• you formed a civil partnership abroad where at least one party had an armed forces connection under the Civil Partnership (Armed Forces) Order 2005

You can convert your opposite sex marriage to a civil partnership if:

• you solemnised a marriage in Northern Ireland
• you solemnised a marriage abroad at a consular or embassy under Part 2 of The Consular Marriages and Marriages under Foreign Law (No.2) Order 2014

or

• You solemnised a marriage abroad where at least one party had a armed forces connection under the Overseas Marriage (Armed Forces) Order 2014

Once a civil partnership is converted into a marriage or a marriage converted into a civil partnership:

• the original civil partnership or marriage ends

and

• the couple is treated as having been married or in a civil partnership since the date of the original event

The conversion converts one legal relationship into another.

Following the conversion, the couple will get a marriage or civil partnership certificate, dated from when the original relationship was formed.
