What Is a Certificate of No Impediment?
A Certificate of No Impediment (CNI) is a government document that certifies you are legally free to marry. It proves you're not already married, not in a civil partnership (where applicable), and there's no legal barrier to your marriage. Some countries call it by different names — Certificate of Freedom to Marry, Single Status Certificate, Affidavit of Single Status, or Marital Status Certificate — but they all serve the same purpose.
Almost every destination we work with requires a CNI. It's one of the most important documents you'll need, and getting it wrong (or getting it too early/too late) is one of the most common reasons marriages get delayed. In this guide, we walk through the exact process for every major country.
United Kingdom: The GRO Process
The UK process is actually quite straightforward — it's legally mandated and consistent across the entire country, which is a relief for British couples.
Issuing Authority: General Register Office (GRO), part of Her Majesty's Passport Office. Your local register office can also issue it.
Cost: £46 per certificate
Processing Time: Minimum 28 days from the date you give notice. You cannot marry abroad before 28 days have passed.
Validity: The CNI is valid for 6 months from the date it's issued. Your wedding must take place within this window.
The Process in Detail:
Visit Your Local Register Office
Go to the register office in the district where you live. You can find yours at www.yourlocal.gov.uk. You must visit in person. Bring both your passport and your partner's passport (if your partner is also giving notice).
Give Notice of Marriage Abroad
Tell them you're getting married abroad and in which country. Complete the notice form. The registrar will ask standard questions about your nationality, place of birth, occupation, and your partner's details. If you're both British and giving notice, you both must be present (or your partner can give notice at a different register office on the same day or earlier).
Wait 28 Days
The 28-day notice period begins the day after you give notice. You cannot marry before this period is complete. This is non-negotiable. Plan your wedding for at least 29 days after your notice date.
Collect Your CNI
After 28 days, return to the register office (or request by post) to collect your Certificate of No Impediment. You'll receive one document per person. Cost: £46 each.
Get It Apostilled
The CNI must be apostilled before submitting it abroad. Send it to the FCDO Legalisation Office (see our apostille guide for details). Processing time: 2-3 weeks. The apostille confirms the signature and seal are genuine.
Timeline Example: Give notice on January 1 → 28-day wait → Collect CNI on February 1 → Apostille takes 2-3 weeks (ready by ~February 15) → Valid for 6 months until August 15. This means your UK wedding abroad must happen between February 15 and August 15.
Special Circumstances: If you've been divorced, widowed, or in a civil partnership, bring your decree absolute, death certificate, or dissolution order. The registrar will still issue a CNI, but these documents are required to prove your freedom to marry.
United States: The Affidavit of Single Status
The United States does not issue a Certificate of No Impediment. Instead, foreign marriages are typically recognized based on an Affidavit of Single Status (also called a Declaration of Single Status or Affidavit of Freedom to Marry).
What It Is: A self-declaration, usually notarized, stating you are unmarried and free to marry. Most US couples can simply sign a statement before a notary public.
Cost: $0-25 (notary fees vary; some notaries charge $5-25 per document)
Processing Time: Same day. You can get a notarized affidavit immediately.
The Process:
Option 1 (Easiest): Find a notary public near you. You can search at www.notary.net or ask your bank (many offer free notary services to customers). Visit the notary with a blank piece of paper or a simple statement like: "I [Your Name], born [Date of Birth], am a citizen/resident of [State], and to the best of my knowledge, I am free to marry and have no legal impediment to marriage." Sign it in front of the notary. They'll stamp it with their seal. Cost: $0-20. Take this to your destination country.
Option 2 (More Official): Get a notarized affidavit from your US embassy or consulate in the country where you're marrying. They can issue this on short notice. Schedule an appointment on the embassy website. You'll need your passport. They'll charge a small fee (typically $50-100) but provide an official embassy-sealed document, which some destinations prefer.
Option 3 (For Those Living Abroad): If you're living outside the US, visit the nearest US embassy or consulate. They can issue a notarized Affidavit of Single Status or direct you to an approved local notary.
Apostille Requirement: The affidavit should be apostilled before submitting it abroad. Many destinations require the notary seal to be certified by the Secretary of State. Get the affidavit notarized, then mail it to your state's Secretary of State for apostille (1-2 weeks processing).
France: The Maire (Mayor's Office)
Issuing Authority: Mairie (town hall) in the commune where you're registered or where you were born
Cost: Free or minimal (€5-10)
Processing Time: 1-5 days
The Process: Visit the mairie with your passport. Request a "certificat de célibat" (certificate of single status) for the purpose of marriage abroad. They'll issue it on the spot or within a few days. The document is straightforward and widely recognized.
Spain: Registro Civil (Civil Registry)
Issuing Authority: Registro Civil in your area
Cost: €25-40
Processing Time: 1-2 weeks by mail; same day in person if you visit
The Process: Spanish citizens can obtain a "Certificado de Soltería" (Single Status Certificate) from their local registry office. Non-Spanish residents living in Spain request it through the registry office. If you're abroad, you can request it by mail or through your consulate. Processing is efficient, especially if you have Spanish documentation.
Germany: Standesamt (Registry Office)
Issuing Authority: Standesamt (civil registration office) where you're registered
Cost: €15-30
Processing Time: 1-2 weeks
The Process: Request an "Ehefähigkeitszeugnis" (Certificate of Marriageability). Submit by mail or in person with your passport. Some Standesämter have streamlined processes for couples marrying abroad.
Italy: Comune (Municipality)
Issuing Authority: Comune (municipality office) where you're registered
Cost: €25-50
Processing Time: 2-5 days if you visit in person; 1-2 weeks by mail
The Process: Request a "certificato di stato libero" (single status certificate). Italian municipalities are generally efficient with this process. Many can provide same-day service if you visit in person.
India: District Magistrate or Consulate
Issuing Authority: District Magistrate (or Sub-Divisional Magistrate) in your district; alternatively, the Indian consulate in your country of residence
Cost: INR 1,000-3,000 (approximately $12-36)
Processing Time: 2-4 weeks (through District Magistrate); 3-5 weeks (through consulate). This is the longest wait time of any country.
The Process: Indian citizens need a marriage certificate or affidavit from the District Magistrate confirming single status. The process requires:
1. Prepare an Application: Write a letter requesting a certificate of single status for marriage abroad. Include your full name, date of birth, nationality, and destination country.
2. Gather Documents: Passport (copy), birth certificate or any document proving your marital status, and the completed application form (available at the District Magistrate's office).
3. Submit: Visit the District Magistrate's office in person (if in India) or submit through your nearest Indian embassy/consulate (if abroad). Processing through embassies is often more reliable.
4. Follow Up: The District Magistrate may request additional verification or an interview. Stay in touch to expedite the process.
Pro Tip: If you're living outside India, it's often faster to apply through your nearest Indian embassy or consulate. Processing is more streamlined and the document carries embassy authority.
Middle East (UAE/Abu Dhabi): Marriage Bureau
Issuing Authority: Marriage Bureau or General Authority of Islamic Affairs (depending on your religion and residency status)
Cost: AED 100-300 (approximately $27-82)
Processing Time: 1-3 days
The Process: If you're a resident of the UAE, visit the Marriage Bureau with your passport and residency document. If you're arriving as a tourist, you can request a single status certificate from the Marriage Bureau as part of the marriage application process. The process is straightforward in Abu Dhabi.
Australia: State Registry
Issuing Authority: Registry of Births, Deaths & Marriages (state-based)
Cost: AUD 25-50 per certificate
Processing Time: 1-2 weeks; many states offer expedited service (1-3 days for additional $50-100)
The Process: Request a "Certificate of Single Status" through your state's registry website. Most states now allow online applications. Provide your full name, date of birth, and destination country. The certificate is issued and posted or delivered within days.
Canada: Provincial Vital Statistics
Issuing Authority: Provincial Vital Statistics office
Cost: CAD 25-50
Processing Time: 5-10 business days
The Process: Contact your provincial vital statistics office (varies by province: Ontario, British Columbia, Alberta, etc.). Most provinces require an application form and photocopied ID. Some offer online services with rapid turnaround.
South Africa: Department of Home Affairs
Issuing Authority: Department of Home Affairs (Vital Registration)
Cost: ZAR 80-150 (approximately $4-8)
Processing Time: 2-4 weeks
The Process: South African citizens request a "Certificate of Status" from the Department of Home Affairs. Provide your ID number, passport, and marriage destination. Processing is straightforward though sometimes slow due to administrative backlogs.
Nigeria: Marriage Registry
Issuing Authority: Marriage Registry (varies by state) or through embassy if abroad
Cost: NGN 10,000-30,000 (approximately $6-18)
Processing Time: 2-3 weeks (can be faster in major cities like Lagos)
The Process: Nigerian citizens living in Nigeria visit the marriage registry in their state with their passport and request a single status certificate. If living abroad, visit the nearest Nigerian embassy or consulate. Processing is generally efficient in major consulates.
Common CNI Mistakes (And How to Avoid Them)
Getting the CNI Too Early (Expired Documents)
Most destinations require a CNI issued within 30-90 days of the wedding ceremony. If you get it months in advance, it may be rejected as expired. We time CNI requests precisely to arrive 60-75 days before your ceremony, ensuring it's fresh but already in hand.
Forgetting to Apostille the CNI
The CNI must be apostilled before submission abroad. Many couples submit the non-apostilled version and have their documents rejected. Remember: apostille is a separate step after you receive the CNI.
Not Accounting for the 28-Day UK Notice Period
UK couples must give 28 days' notice before collecting the CNI. If you want to marry in 8 weeks, you need to give notice immediately — there's no shortcut. Plan ahead accordingly.
Language Barriers
If your CNI is issued in another language (French, Spanish, German, etc.), many destinations require a certified English translation along with the apostille. Ensure you obtain both before traveling.
Divorce/Widowhood Documentation Missing
If you've been divorced or widowed, you must provide the decree absolute or death certificate alongside your CNI application. Don't assume they already have this on file. Provide it proactively.
How We Manage CNI Coordination
CNI coordination is a central part of our service. Here's what we do:
Assess Your Specific Situation
We determine which country/authority issues your CNI based on your nationality, residency, and marital status. We advise whether you qualify for streamlined EU processes, whether you need a US affidavit instead, or whether Indian consular processes apply to you.
Build a Timed Workflow
We create a precise timeline. For UK couples, we schedule your 28-day notice to end 60-70 days before your wedding. For US couples, we arrange notarization 70 days out. For Indian couples, we initiate the consulate process even earlier. Timing is everything.
Guide Document Collection
We walk you through exactly what documents you need, where to get them, and in what order. If you need a decree absolute along with your CNI, we ensure that's available first. We check everything before submission.
Coordinate Translation & Apostille
Once the CNI arrives, we arrange professional translation (if needed) and apostille. For UK CNIs, we submit to FCDO. For others, we coordinate with appropriate authorities. Everything is tracked and verified.
Final Delivery
The apostilled CNI is securely couriered to you weeks before your trip. You have it in hand, fresh, and ready to take with you. No last-minute scrambling.
Real Timeline: UK Couple Marrying in Cyprus (12 Weeks Out)
Week 1: We assess their situation. Both are UK citizens, never married. CNI required.
Week 2: They visit their local register office and give notice of marriage abroad (to Cyprus).
Week 5-6: After 28 days, they collect their CNIs from the register office. Cost: £92 for both (£46 each).
Week 6: We submit both CNIs to the FCDO Legalisation Office for apostille.
Week 8-9: Apostilles arrive at FCDO, sent to us for verification and courier to clients.
Week 10: Clients receive apostilled CNIs in the post. Documents are fresh and valid for 6 months.
Week 12: They travel to Cyprus with all documents in order. Marriage ceremony proceeds smoothly.
Total CNI + Apostille Cost: £92 + £60-80 = £152-172 ($190-215)
