If you wish to get married abroad, you will need a no impediment apostille certificate.
We can apostille your no impediment certificate in one or two days if you have your certificate ready. Getting a new certificate of no impediment from the GRO takes 28 days. We cannot request the certificate on your behalf.
What it is:
A certificate of no impediment (abbreviated as CNI or CONI) is a document that states that you can legally enter a civil partnership or marriage abroad. It shows that there is no objection to the proposed marriage. 
Frequently used for:
A certificate of no impediment is required when British nationals are getting married abroad.
Original or copy:
Only the original document can receive an apostille certificate.
Some countries may not require a certificate of no impediment. For instance, it might not be necessary when getting married in another Commonwealth country when you are a British national.
Suppose you have lost your certificate of no impediment. In that case, you can replace it from your local General Register Office, GRO (this is where you will also receive your marriage certificate, full birth certificate, and death certificate.)
How much does it cost?
A standard FCDO apostille for a certificate of no impediment starts from £79.
However, our apostille services will vary depending on the services you select, such as:
- Same-day service
- Notary and solicitor certification
- Embassy attestation

Where can I apply for a certificate of no impediment?
You can apply for a certificate of no impediment at the local registry office. The Register Office will require a notice appointment, and if there are no objections to your intentions to marry outside of the UK, then the certificate will be provided.
How long does it take to receive a certificate of no impediment?
It takes 28 days to receive your certificate of no impediment. 
After you visit the UK local registration office (or civil registry), your intended nuptials will be announced publicly for 3-4 weeks, and if there are no objections, you will be issued your certificate.
Sometimes, the British consulate in the country where you are planning on getting married may exchange your no impediment certificate for a local certificate from that country.
In case I do not have a certificate of no impediment, what other options are available?
If you do not have a certificate of no impediment, you can use a statutory declaration. This document provides evidence of your marital status and states that you are free to marry.
It will require an apostille service to be used abroad.
What information does a certificate of no impediment contain?
The certificate of no impediment contains specific information that provides evidence that you can marry abroad and have fulfilled all of the legal requirements. The following information can be found in the document:
Once you receive your certificate of no impediment, you can present it to the overseas authorities registry office. 
This document will need an apostille certificate to prove its authenticity.
Please note that: Each country is usually different when it comes to getting married abroad. Please get in touch with the local authorities to confirm the requirements and the different rules for weddings in their country.
What other documents are needed for a civil partnership or marriage abroad?
Other than the certificate of no impediment, there are other UK documents you may be required to present to the register office to marry abroad, such as:
What if you are getting married in a Commonwealth country?
If you are getting married in a commonwealth country and are from England, you will not require a certificate of no impediment. This is because this document is not required between two commonwealth countries.
How long is a certificate of no impediment valid?
The impediment certificate does not have an expiry date. Still, each country has its own rules regarding its validity, and it goes without saying that once you get married, the document loses its purpose.
You should, however, investigate the rules months prior to your wedding.
What if I am a resident of a foreign country?
When you’re a British citizen living in a foreign country, be sure to consult with the closest British embassy in that country on how to attain your certificate of no impediment and get married.
What if the certificate of no impediment is in a different language?
If your apostille certificate of no impediment is in a language other than that of the country you wish to marry, then you will require translation services.
A certified translation of your impediment certificate will be attached to the apostille certificate to make the document valid and usable by the registration service of the country you wish to marry.
Most apostille agencies provide translation services. Enquire beforehand so you can obtain all of these certificate services at the same time.
