Can a UK Certificate of No Impediment Be Apostilled?

Example of a UK Certificate of No Impediment (illustrative sample)

Yes, the original CNI

A CNI is needed to marry in many countries outside the UK, most often Greece, Italy, Morocco and Spain. It is issued by a UK register office, so the FCDO can apostille the original certificate directly, with no solicitor certification. Any CNI issued by a UK register office, in England, Wales, Scotland or Northern Ireland, can be apostilled at the same price.

How to Get an Apostille on Your CNI

What Is a Certificate of No Impediment?

A Certificate of No Impediment (CNI) confirms that there is no legal reason why you cannot marry. It is issued by your local UK register office after you give notice of your intended marriage abroad. The notice period is usually 28 days, although this can depend on your circumstances, and the CNI is issued at the end of it if there are no objections. Each partner usually needs their own CNI.

A CNI shows your name, age, marital status, occupation, address and how long you have lived there, your nationality and where you intend to marry. Depending on the register office, it is printed on blue or white paper. Both versions can be apostilled.

Countries That Most Often Ask for an Apostilled CNI

Where Our Customers Use Them

Based on our CNI orders, these are the most common destinations (this list is not exhaustive):

Marrying in a Commonwealth Country?

The UK does not issue Certificates of No Impediment for marriages in Commonwealth countries, such as Malta, Mauritius and Barbados. A Statutory Declaration, signed in front of a UK solicitor or notary and then apostilled, is usually used instead. See our statutory declaration apostille page.

How Recent Does Your CNI Need to Be?

A CNI is usually required to be no more than 3 months old for countries such as Greece, and Italy will only accept a CNI that is less than 3 months old on the date of the ceremony. Plan backwards from your wedding date, allowing for the notice period, so your CNI is still recent enough. Most countries also ask for a sworn translation after the apostille. See our translation service.
