Italy is one of the most popular wedding destinations for UK couples, and because it is a member of the Hague Apostille Convention, the UK side of the legalisation process is straightforward. The challenge is the Italian side - and specifically the strict requirements around document currency and sworn translation that catch couples out more often than any other aspect of the process. Working backwards from the ceremony date is the only reliable way to make sure everything arrives in time.
The three-month rule - and why it matters
Italy requires the Certificate of No Impediment to be less than three months old on the date of the ceremony. This is not a guideline - Italian comuni enforce it. It means there is a tight window between obtaining the CNI and getting married. The CNI is issued by a UK register office after a 28-day notice period, which cannot be shortened. Once issued, it must be apostilled by the FCDO. It must then be sworn-translated in Italy by a court-registered translator through a process called asseverazione. All three stages must complete within three months of the ceremony date.
The Statutory Declaration
Alongside the CNI, Italy also requires a Statutory Declaration - a bilingual English and Italian document in which each partner formally declares they are free to marry. It must be signed in front of a UK solicitor or Notary Public. The FCDO then authenticates the solicitor's or notary's wet-ink signature, seal or stamp, and the apostille is physically attached to the document. Because it is already bilingual, the Statutory Declaration does not require sworn translation in Italy - this is one less step compared to the CNI.
If you have been married before
Where a previous marriage ended in divorce, the Decree Absolute or Final Order must also be legalised. The original document bearing a wet-ink signature or wet-ink or embossed seal with a date from the issuing authority can be submitted directly to the FCDO. If the original does not carry those marks, or if submitting a photocopy, it must first be certified by a UK solicitor or Notary Public. It must then be apostilled and sworn-translated in Italy just as the CNI is.
What the FCDO actually does
The FCDO authenticates the wet-ink signature, seal or stamp on each document. The apostille is a physical paper certificate attached to the back of the original. For the CNI, that means the registrar's signature is authenticated. For the Statutory Declaration, the solicitor's or notary's signature is authenticated. The apostille confirms to Italian authorities that those signatures are genuine - it does not verify the content of the documents.
Planning the timeline
Apply for the CNI at a UK register office at least ten weeks before the ceremony to allow for the 28-day notice period, FCDO apostille processing at around ten working days, and sworn translation in Italy.
