Certificate Of No Impediment (CNI)

This document is used to prove that there is no impediment, obstruction or objection to a proposed marriage. Often this document is required by overseas government bodies before they will permit a marriage to take place in that country.

The document shows the names of both parties involved, their names, nationalities, ages, occupations and the country in which they intend to get married.


If English is not the native language of the country in which the marriage is taking place, the document will usually need to be formally translated. Translations are usually attached on top of the original CNI by way of a seal or stamp. For the purposes of legalisation by the Foreign & Commonwealth Office, the FCO will place their apostille on the reverse of the certificate of no impediment.
