Single status certificate explained: Process, requirements & tips

Topics covered in this article >

Planning to marry abroad can feel overwhelming. One document you’ll likely need is a single status certificate. This official document confirms that you’re legally free to marry and do not have a secret spouse hiding somewhere.

Most people don’t know about this document until they need it. And that’s usually when they’re stressed about wedding planning or visa applications.

We’ll break down everything you need to know about getting a single status certificate in the UK without the confusion.

What is a single status certificate?

A single status certificate is an official document that confirms you’re not married. Simple as that. It’s legal proof that shows authorities you’re eligible to marry someone else.

The document goes by several names depending on where you’re from:

Certificate of No Impediment (CNI) in the UK
Bachelorhood certificate in some countries
Certificate of freedom to marry
Certificate of celibacy

The purpose remains the same. Foreign governments want to make sure you’re not committing bigamy. They need official confirmation that you’re single, divorced, or widowed before they’ll let you marry in their country.

Think of it as a background check for your love life. The certificate shows there are no legal barriers stopping your marriage.

Quick note: Once you get your CNI, you’ll likely need an apostille to use it abroad. Most countries won’t accept it without proper legalisation. London Apostille Services Ltd handles CNI apostilles from £87. Send us the original document (no photocopies), and we can complete the process the next day if you’re cutting it close.

Who needs a single status certificate?

You’ll need this document if you’re planning to marry outside your home country. Most foreign governments require proof of your marital status before they will register your marriage.

UK citizens commonly need it when:

Getting married in European countries (non-Commonwealth)
Marrying someone from a different country
Planning destination weddings in Asia or the Americas

Other situations include:

Legal proceedings involving marital status overseas
Some immigration applications
International adoption processes (for single adopters where destination countries require confirmation of unmarried status)

The requirement isn’t universal, though. Some countries accept alternative documents or have different rules for Commonwealth citizens.

Key types of single status documents

Different countries issue various types of single status documents:

Types of single status documents

UK documents

In the UK, you’ll encounter three main types of single status documents depending on your situation:

Certificate of No Impediment (CNI): The most common type in the UK. Your local registry office issues this after a 28-day notice period. It’s only available to British citizens and costs only £42.
Statutory Declaration of Single Status: A sworn statement you make before a solicitor or notary. This works when you can’t get a CNI or need something faster. Solicitors charge a minimum of £5 for witnessing, while notaries typically charge more.
Letter of No Trace: The General Register Office issues this letter of no trace when they can’t provide a CNI. It confirms they have no record of your marriage in England and Wales.

International variations

Other countries have their own versions of single status certificates with different names and processes:

United States: Issues a “Certificate of No Marriage Record” or “Single Status Affidavit” through county clerk offices.
Australia: Provides “Single Status Certificates” through state Births, Deaths and Marriages registries.
Canada: Offers a “Statement in lieu of Certificate of Non-Impediment” since they don’t issue traditional certificates.
India: Issues “Bachelorhood Certificates” through Sub-Divisional Magistrate (SDM) offices or embassies for overseas residents.
Philippines: Provides a “Certificate of No Marriage” (CENOMAR) through the Philippine Statistics Authority for both locals and foreigners.
Thailand: Issues ‘Single Status Certificates’ (Sor Bor 1) through district offices, valid for 3 months from the issuance date.

Documents required for a single status certificate

Getting your paperwork ready is crucial. Missing documents will delay your appointment, and you’ll need to book again.

When you attend your appointment, you’ll need to provide proof of several things about yourself. Here’s exactly what to bring:

Proving your British nationality

You need to bring one of these documents:

Valid British passport: This is the simplest option if you have one.
British citizenship certificate: If you became a British citizen through naturalisation.
British birth certificate: The requirements depend on when you were born:
- Born before 1 January 1983: Either your full or short birth certificate works.
- Born after 1 January 1983: You need your full birth certificate showing your parents’ details. You’ll also need either your mother’s or father’s birth certificate if they were married when you were born. If your parents weren’t married, only your mother’s birth certificate is accepted.
- Parents born after 1 January 1983: You might need evidence of your grandparents’ nationality, too. This gets complex, so call your registry office for guidance.

If your parents were born outside the UK, you must prove they had British nationality when you were born.

Proving your address

Bring one of these documents:

Current tenancy agreement
Council tax bill from last year
Bank statement from the previous month
Valid driving licence in your name
Utility bill from the previous three months
Mortgage statement from the previous 12 months
A letter from your landlord or property owner confirming that you live there

The landlord’s letter must include their name, address, signature, and confirmation that you’ve lived there for at least eight days before your appointment.

Proving your age

You need to show you’re over 18. Your valid passport covers this requirement.

Name changes

If you’ve changed your name, bring evidence like:

Deed poll
Marriage certificate
Any other official name change documents

Previous marriages or civil partnerships

If you’ve been married or in a civil partnership before, you need specific documents:

For divorce:

England and Wales divorces:

Paper Decree Absolute plus the cover sheet from the court
Electronic Decree Absolute plus the covering email

Divorces from other countries:

Final divorce documents
Certified English translation if the documents aren’t in English

Note: Foreign divorces need clearance from the General Register Office (GRO), which can result in significant delays.

If your current name differs from what’s on your divorce papers, bring evidence linking the names.

For widowed status:

Death certificate of your spouse
If you’re not named on the death certificate, bring a copy of your marriage certificate too

For presumed death:

Presumed death certificate of your spouse

Foreign documents

Any documents not in English need certified translations. The translator must write at the bottom: “I certify this to be a true translation of the document.” They must include their name, address, phone number, and signature.

Getting the wrong translation can derail your entire application. You need certified translations that official bodies accept.

London Apostille Services Ltd handles this for £30 per page, with 3,000 translators covering over 130 languages at a 99.9% accuracy rate. Same-day service is available when you’re up against deadlines.

Get your certified translations sorted before your appointment.

How to obtain a single status certificate

The process varies depending on your location and the type of document you need.

UK residents

If you live in the UK, the standard route is through your local registry office:

Step 1: Contact your local registry office: Find the registry office where births, marriages, and deaths are recorded in your area. You can’t apply online – you need to attend in person.
Step 2: Book an appointment for Certificate of No Impediment: You’ll need to give notice of your intention to marry abroad. This starts the mandatory 28-day waiting period during which your intention is publicly posted.
Step 3: Attend your appointment: Bring all required documents mentioned above and pay the fee. The registrar will collect and verify your information and explain the next steps.
Step 4: Wait 28 days for processing: After the waiting period (to allow for any objections), you can collect your CNI certificate. Some offices can post it to a UK address for an additional fee.

Alternative: Statutory declaration route

If you can’t get a CNI, you can make a statutory declaration instead.

Draft your declaration: Use templates available online or have a solicitor prepare one for you. The declaration must state you’re single and free to marry.
Find a qualified witness: Solicitors, notaries public, or commissioners for oaths can witness your signature. Each has different fees and capabilities.
Sign and authenticate: Sign the declaration in front of your chosen witness. They’ll add their signature and official stamp.

Need your statutory declaration apostilled for overseas use? London Apostille Services Ltd handles the entire process, starting from £97, which includes solicitor certification and FCDO fees.

Get your statutory declaration apostilled in 24 hours.

Example: (Draft)

UK citizens living abroad

Contact the nearest British embassy or consulate. Not all locations offer CNI services, so check first.

Many embassies have reduced services in recent years. You might need to use alternative documentation or apply through the UK.

The role of apostille services for single status documents

Most countries require your single status certificate to be legalised before they’ll accept it. This process varies depending on your destination.

Hague Convention countries

Hague Convention countries include most European nations, the United States, Australia, and several other countries. They require an apostille — a special stamp that authenticates the document.

The process:

1

Get your single status certificate
2

Submit it to the FCDO or a registered apostille agent
3

Receive the apostilled document with authentication

Timeline:

Registered agents: 1-2 days
Direct FCDO application: Up to 20 days

Need it fast? London Apostille Services Ltd offers standard UK apostille and next-day apostille services from £97. Documents received by 10:00 AM are ready by 3:30 PM the following day.

Non-Hague countries

Countries like Qatar, Egypt, and Kuwait aren’t part of the Hague Convention. They require embassy legalisation in addition to an apostille.

You’ll need to go through extra steps at the embassy or consulate. It’s slower and more expensive than getting an apostille.

For non-Hague countries, London Apostille Services Ltd handles the complete embassy attestation process — we arrange the FCDO apostille and then have it stamped at the embassy.

Important notes:

Get your apostille after obtaining the certificate, not before
Don’t apostille too early — some countries want recent stamps
E-apostilles aren’t available for CNIs — only paper versions work

Mistakes to avoid when applying for a single status certificate

Common errors can delay your application or cause rejection.

Here’s what to watch out for:

Wrong birth certificate type: Using short birth certificates instead of full ones. Full certificates show your parents’ details, which registrars need for verification.
Name inconsistencies: Ensure names are consistent across all documents. If you’ve changed your name, bring evidence of the change.
Missing divorce papers: If you’re divorced, you need the final Decree Absolute. Separation papers or other documents will not suffice.
Late applications: Begin the process at least two months prior to your wedding. The 28-day notice period can’t be shortened. You also need time to book your appointment, plus additional processing time if your certificate needs an apostille or embassy attestation.
Wrong registry office: Apply at the office in your area of residence, not just any convenient location.
Insufficient research: Check the specific requirements of your destination country. Don’t assume all countries accept the same documents. You may not even need a single status certificate.
Missing translations: Foreign documents need certified translations. Machine translations or uncertified versions won’t be accepted.
Ignoring local laws: Research the marriage laws in your destination country to ensure compliance. Some have residency requirements or other restrictions.
Wrong document type: Some countries prefer statutory declarations over CNIs as your single status certificate. So you may not need it in the first place. Check before you apply.

Frequently asked questions (FAQs)

Below are a few frequently asked questions surrounding this topic:

Is a single status certificate mandatory for a court marriage?

No, you don’t need a separate single status certificate for UK court marriages. The UK marriage process includes a “giving notice” period that serves the same purpose.

What is the validity period of a single status certificate?

UK certificates don’t have official expiry dates, but receiving countries set their own acceptance periods.

Most countries accept certificates for 3-6 months from the date of issue. Always check with your destination country’s requirements.

Is the certificate accepted in all countries?

No, acceptance varies by country. Each nation sets its own marriage documentation requirements.

Hague Convention countries generally accept apostilled UK certificates, but may have additional requirements.
Commonwealth countries often don’t accept UK CNIs. The UK government doesn’t issue CNIs for marriages in Commonwealth nations due to different legal systems.
Non-Hague countries may require embassy legalisation instead of apostilles.

How do I get a single status certificate if I’m already abroad?

Contact the nearest British embassy or consulate first. Many locations have reduced CNI services, so you may need statutory declarations instead.

You can also authorise someone in the UK to apply on your behalf, provided you provide the proper documentation.
