Getting married overseas should feel like picking venues, outfits, and playlists. In reality, most couples hit the same wall first: paperwork.
If you are a UK citizen getting married abroad, the overseas authority will usually ask for a set of UK documents to prove who you are and that you are legally free to marry. Then comes the part that catches people out: many countries will not accept UK documents until they have been legalised, usually with an Apostille for marriage (or in some cases, consular legalisation).
This guide is your practical, all-in-one breakdown of documents for international wedding planning, including the Certificate of No Impediment (CNI), divorce proof, translations, and the steps to legalise marriage abroad properly.
The exact documents for overseas marriage depend on the country where you are marrying or registering a civil partnership, so always check the destination’s rules first. You must always confirm the exact requirements with the country you have chosen.
Document Checklist for Overseas Wedding
Print this section and tick off each item as you go. If you are from the UK and are getting married abroad, most overseas authorities will request some combination of the following.
Core documents (most common):
- Full UK birth certificate (long version)
- Valid passport
- Proof of address (recent utility bill or bank statement)
- Certificate of no impediment to marriage for each person (CNI)
- Apostille for these marriage documents (if the destination requests the Hague Apostille)
If you have been married before
- Decree absolute (or final order or divorce)
- Apostille on decree absolute
If you are widowed
- Death certificate of previous spouse
- Apostille on death certificate
If the destination needs extra formalities
- Certified passport copy (if requested)
- Statutory declaration or affidavit (if the country asks for one)
- Certified translation of key documents (if the country does not accept English)
- Hague Apostille Legalisation (Check which countries are part of the Hague Convention)
- Consular legalisation (only if the country is not under the Hague Apostille Convention)
Before you send anything
- Check the destination’s document “freshness” rules (some require documents issued within 3 to 6 months)
- Confirm whether they need originals, certified copies, or both
- Double-check spelling matches across documents (names, middle names, accents, hyphens)
What does it mean to “legalise” a UK document for an overseas wedding?
When a country asks you to “legalise” paperwork, they are asking for official authentication so they can trust a foreign document.
This can be done via the Apostille, Consular legalisation or both together.
Apostille (Hague Apostille Convention countries)
If the destination country is part of the Hague Apostille Convention, UK documents are typically legalised by attaching an apostille. The UK Legalisation Office (FCDO) checks the signature, stamp, or seal and then issues the apostille certificate.
This is why you will hear couples using phrases like apostille marriage abroad, apostille for marriage, or “we need to legalise marriage abroad”.

Consular legalisation (non-Hague countries)
If the destination is not part of the Hague Convention, you may need extra steps after the apostille, often involving the destination country’s embassy or consulate. This is usually called consular legalisation.
Check if the country is part of the Hague Apostille Convention
Documents most commonly required from Brits for overseas marriage
Below are the documents that overseas authorities most frequently request from UK citizens. The exact list varies, but these are the most common for processing marriage cases.
Birth certificate:
Many countries prefer the long version birth certificate because it includes more detail. If your birth certificate is older, damaged, or not easily accepted, it may be worth ordering a fresh official copy from the GRO (General Register Office) before starting legalisation.
You will often need to:
- Provide the original or a properly certified version (depending on the country)
- Obtain an apostille if the destination requires it
- Translate it if the destination does not accept English documents
Passport and ID (often as a certified copy):
Some authorities accept a simple photocopy. Others require an Apostilled copy, which must first be a solicitor-certified or notary-certified copy before the apostille step.
WLS can help with Notary Public certification and Solicitor Certification where required.

Proof of address
This can be requested in many destinations, especially where residency rules, local registrations, or appointment bookings are involved. Requirements differ widely, so confirm with your venue, local registry office abroad, or embassy guidance.
Certificate of No Impediment (CNI): the document that causes the most delays
If you only remember one phrase from this article, make it this: the Certificate of No Impediment is often the document that slows everything down.
The UK Government notes that you might need a document to prove you are free to marry, such as a certificate of no impediment (CNI) or an affirmation.
What is a certificate of no impediment CNI?
A CNI is an official document that confirms there is no legal reason you cannot marry. In plain English, it is proof that you are not currently married, and that there is no known legal barrier to your planned marriage.
This is why it is often requested when applying for what people call a marriage license abroad.
How to get a certificate of no impediment
In most cases, you obtain a CNI through your local register office. The process normally involves giving notice and waiting for the notice period to pass before the certificate is issued. Your destination country might also require the CNI to be recent, so do not apply too early.
To apply, you will usually need to book an appointment with the registrar and provide details of your intended marriage, including the country where the marriage will take place and information about your partner.
Once your notice has been given, the registrar will display it publicly at the register office for the required notice period. This allows time for any legal objections to be raised. If no objections are received, the Certificate of No Impediment will normally be issued after approximately 3 to 4 weeks.
The fee is typically around £40 per person, although this may vary slightly depending on the local authority. Some register offices may also have additional requirements, so it is advisable to check with your local office before making an appointment.
Some countries may accept alternatives such as an affidavit, statutory declaration, or local embassy-issued equivalent, but you should always confirm what the destination will accept.
Can I get a certificate of no impediment online?
In practice, you can often find information online and sometimes book steps online, but the process generally still involves working with your local register office and following their notice process.
If a country will accept an alternative document (such as an affidavit, statutory declaration or affirmation), that may change what you need, but you must confirm this with the overseas authority first.
Certificate of no impediment Apostille
Many destinations require the CNI to be legalised, which usually means getting the certificate of no impediment apostille added. This step is a common part of an apostille marriage abroad package of documents.

Decree Absolute: proof you are legally free to marry again
Have you been married before? You might need a decree absolute to prove your previous marriage has ended
If you have been married before, overseas authorities will almost always ask for proof that the marriage has legally ended. This is not bureaucracy for the sake of it. It is how the overseas authority confirms you are free to marry under their law and that your marriage can be properly registered.
What is a decree absolute?
A decree absolute is the legal document that finalises a divorce if the court issued your divorce application before 6 April 2022. For divorces issued on or after 6 April 2022, the equivalent document is called a final order.
The Government guidance is also very clear on why this matters: once you have the final order or decree absolute, you are divorced and free to marry again, and you should keep it safe because you will need to show it if you remarry.
Do you need an apostille for a decree absolute?
In many cases, yes. If the overseas authority requires your divorce document to be legalised, you will need an apostille on the decree absolute or final order.
The exact process for the Apostille of the decree absolute depends on how it was first issued to you:
- Do you have an ink-signed or wet-stamped document? If yes, these can usually be Apostilled directly.
- Do you have an electronic PDF copy that was sent to you via email? It will likely need to be certified by a Solicitor or Notary Public before it can receive the Apostille.

What if you lost your decree absolute or final order?
The Government confirms you can apply to the court for a copy if you lose your final order or decree absolute here: https://www.gov.uk/divorce/finalise-your-divorce
It is worth doing this early, because many couples only realise they cannot find it when the overseas authority requests it with a strict deadline.
Translations: when “English is fine” is not fine
Even when a country is used to dealing with UK nationals, it may still require certified translations for official registration. Wedding documentation guidance also points out that embassies or consulates may provide lists of certified translators, and that some destinations have strict submission timelines.

Timing matters more than people realise
A painful pattern we see is couples preparing too late, or preparing too early and then discovering documents have validity windows. Some destinations want documents submitted months in advance, others only days before, and the timeline varies.
If you want to avoid last-minute panic, treat document preparation like booking the venue: early enough to be safe, but not so early the paperwork expires.
Marriage abroad recognised in UK: will your overseas wedding count back home?
Marriage abroad is legal in the UK?
In most cases, yes. If the marriage is legally valid in the country where it took place and you followed local rules, it is usually recognised in the UK.
You generally do not need to “register it again” when you return, but you may need:
- Official copies of the overseas marriage certificate
- A certified translation if it is not in English
- An apostille on the foreign marriage certificate for certain UK or international administrative uses (requirements vary).
Main countries where British nationals usually get married
Destination choices change year to year, but wedding industry search and planning data regularly point to Mediterranean favourites, plus a handful of long-haul options.
Common choices for Brits include:
- Greece
- Italy
- Cyprus
- Spain
- Portugal
- France
- Turkey
- United States
- Australia
- Caribbean destinations (for example Jamaica and Barbados)

People Also Ask: overseas wedding paperwork
What do you need to get married overseas?
You need two things: the correct document list for your destination, and the correct authentication method. The UK Government advises you must follow the process in your chosen country, and you may need documents like a certificate of no impediment or an affidavit.
In practice, most couples also need to apostille the paperwork so the overseas authority can accept UK documents. If the country is not part of the Hague Apostille Convention, you may also need consular legalisation. Plan for time, especially if documents must be issued recently or submitted months ahead.
Do I need a certificate of no impediment?
Very often, yes. A CNI is one of the most common requirements for a UK citizen getting married abroad, because it confirms you are legally free to marry. The UK Government explicitly lists the certificate of no impediment as an example of a document you might need to prove eligibility.
Some countries accept alternatives such as an affidavit or affirmation, but this is destination-specific, and the safest approach is to confirm directly with the overseas authority or the person conducting the ceremony.
What documents are needed to marry a foreigner?
The core documents are usually the same as any overseas marriage: identity, proof of address, and proof you are free to marry. If your partner is a national of the destination country, there may be additional local requirements, such as residency documents, local civil registry records, or extra verification steps. From the UK side, you should expect to provide a birth certificate, passport, and often a certificate of no impediment to marriage. If you have been married before, add a decree absolute or final order. Many destinations will still require you to legalise marriage abroad paperwork using an apostille, and some will require certified translations.
Do I need a Hague apostille for international marriage?
If the destination is part of the Hague Apostille Convention and they request legalisation, then yes, you will likely need an apostille. The FCDO attaches an apostille after checking signatures, stamps or seals against records.
This is why couples need and apostille for marriage documents. Common documents that may need an apostille include the birth certificates, CNI, and divorce documents. If the destination is not part of the Hague system, you may need consular legalisation after the apostille. Always confirm the required route with the overseas authority because assumptions cause delays.
What is a decree absolute?
A decree absolute is the final divorce document for cases issued before 6 April 2022. For divorces issued on or after 6 April 2022, the equivalent is a final order.
Overseas authorities often ask for this if you are getting married overseas and have been married before, because it proves the previous marriage ended legally. The UK Government guidance also notes you should keep the final order or decree absolute safe because you will need it to remarry or prove marital status.
If the overseas authority requests legalisation, you may need to apostille marriage abroad divorce documents as part of your wedding paperwork.
