Planning a wedding abroad is exciting right up until the paperwork arrives. Foreign marriage authorities have specific requirements for UK documents, and understanding what they need - and in what format - before you travel makes everything considerably smoother. This guide covers the documents most commonly required and what you need to do with each of them.
The Certificate of No Impediment
The Certificate of No Impediment (CNI) is the document most frequently requested by foreign marriage authorities. It is issued by a UK register office and confirms that there is no legal barrier to your marriage. For most countries, the CNI must be the registrar-signed original - photocopies and scans are not accepted. It must be apostilled by the FCDO before it will be recognised abroad. CNIs are typically valid for three months from the date of issue, so plan the timing carefully and work backwards from your wedding date when applying.
Letter of No Trace
Some countries - particularly those with stricter marriage registration procedures - also ask for a Letter of No Trace alongside the CNI. This is a document issued by the General Register Office confirming that no marriage record exists in the applicant's name. It must be the GRO-signed original and must be apostilled before use abroad.
If you have been married before
Foreign authorities will always ask for evidence of how a previous marriage ended. A Decree Absolute confirming divorce is accepted either as an original or as a certified photocopy - but the photocopy must be certified by a UK solicitor or Notary Public before it can be apostilled. A Death Certificate, where the previous spouse has died, must be an original or a certified copy issued by the GRO, a local registry office, the National Records of Scotland, or the General Register Office for Northern Ireland. Digital printouts and email PDFs cannot be legalised and will be rejected.
Hague Convention countries vs Non-Hague countries
For countries that are members of the Hague Apostille Convention - which includes Spain, Cyprus, Greece, Portugal, Italy, France, the USA, Australia and most Commonwealth destinations - an apostille from the FCDO is the final authentication step on the UK side. For countries outside the Convention, including the UAE, Qatar and a number of others, the apostilled documents must also go through embassy attestation in London before they will be accepted by local marriage authorities.
Translations
Many countries require certified or sworn translations of UK documents into the local language. Italy and Greece in particular often insist on sworn translations of the CNI and birth certificate. Confirm translation requirements with the local registry office or your wedding planner well before the ceremony date.
Allow more time than you think you need
The CNI application process involves a 28-day notice period at a UK register office. That period cannot be shortened. Add apostille processing time on top - currently around ten working days at £45 per document for standard postal service - plus any translation and embassy attestation where required. For most destinations, applying at least three to four months before the wedding date is advisable.
