If you are a U.S. citizen planning to marry abroad, you may have been asked by the foreign government for a Certificate of No Impediment to Marriage (CNI). This document—also known as a Certificate of Freedom to Marry, Certificate of No Record of Marriage, or Single Status Affidavit—is a formal declaration that you are legally free to marry and that no legal obstacles exist to prevent your marriage[reference:0][reference:1].
However, there is a critical fact that many U.S. citizens do not realize until they are deep into the process: the United States does not have a federal authority that issues a Certificate of No Impediment[reference:2]. Unlike many other countries that have a centralized civil registry, the U.S. leaves marriage records to the states, and no single federal agency can certify that you are unmarried[reference:3][reference:4].
This means you cannot walk into a U.S. government office and walk out with an official "Certificate of No Impediment." Instead, you must create a substitute document—typically a Single Status Affidavit or a Certificate of No Record of Marriage—that is notarized and then apostilled to be recognized abroad[reference:5][reference:6]. As of July 2026, this is the standard workflow for U.S. citizens marrying in almost any country that requires proof of marital status.
Key Rule: The U.S. does not issue a federal Certificate of No Impediment. Instead, you must obtain a notarized Single Status Affidavit or a Certificate of No Record of Marriage from your state or county, and then have it apostilled by the state Secretary of State. Some countries also accept an affidavit signed and notarized at a U.S. embassy or consulate abroad[reference:7].
What Is a Certificate of No Impediment and Why Is It Required?
A Certificate of No Impediment is a document that confirms, after official searches, that no lawful obstacle exists to your intended marriage[reference:8]. Foreign governments require this to ensure that you are not already married and that you are legally eligible to marry in their country[reference:9]. The document may be called different names depending on the country: "Certificate of No Impediment to Marriage," "Certificate of Freedom to Marry," "Certificate of Single Status," "Letter of No Impediment," or "Affidavit of Eligibility to Marry"[reference:10][reference:11].
For U.S. citizens, the requirement for this document stems from the fact that the U.S. has no national marriage registry. Foreign authorities need proof that you are not already married, and because they cannot verify this directly with the U.S. federal government, they rely on a sworn statement from you, backed by official state records.
Follow These Steps to Obtain Your Certificate of No Impediment
The process varies depending on whether you are currently in the U.S. or already abroad. Below is a step‑by‑step guide for both scenarios.
Option 1: Obtaining a State-Issued Document in the U.S.
This is the most common and widely accepted path. You will obtain a document from your state or county that confirms there is no record of marriage for you.
- Contact your local County Clerk's office or state vital records office. Request a document that confirms your unmarried status. Depending on the state, this may be called a "Certificate of No Record of Marriage," "Single Status Certificate," or "Certificate of Freedom to Marry"[reference:14][reference:15]. Some states issue this document; others do not. If your state does not issue such a document, you will need to draft a Single Status Affidavit instead (see Option 2 below).
- Complete the application (if required). Some counties, such as New York City, require you to apply in person at the City Clerk's office[reference:16][reference:17]. Others allow mail-in or online requests. Check with your local office for specific instructions.
- Provide proof of identity and residency. You will typically need to submit a copy of your government‑issued ID (driver's license or passport) and proof of your current address.
- Pay the required fee. Fees vary by county and state, typically ranging from $10 to $30 per copy.
- Receive the document. The county or state will issue a certified copy bearing an official seal. This is the document you will submit for apostille.
Option 2: Drafting a Single Status Affidavit
If your state does not issue a Certificate of No Record of Marriage, or if you need a document more quickly, you can draft a Single Status Affidavit—a sworn statement declaring that you are unmarried and legally free to marry[reference:18].
- Draft the affidavit. The affidavit should include:
- Your full name and date of birth.
- Your U.S. passport number.
- A clear statement of your current marital status (single, divorced, or widowed)[reference:19][reference:20].
- If divorced or widowed, include the date the previous marriage ended[reference:21].
- A declaration that you are legally free to marry.
- Have the affidavit notarized. In the U.S., a Single Status Affidavit must be notarized by a notary public to be valid for international use[reference:22]. The notary will verify your identity and witness your signature. Do not sign the affidavit before you are in front of the notary.
- Obtain the apostille. Once notarized, the affidavit must be apostilled by the Secretary of State of the state where the notary is commissioned[reference:23]. This certifies the notary's authority and makes the document recognizable in foreign countries that are members of the Hague Convention.
Option 3: Obtaining an Affidavit at a U.S. Embassy or Consulate Abroad
If you are already outside the United States, you may be able to obtain a notarized affidavit at a U.S. embassy or consulate[reference:24][reference:25].
- Make an appointment at the nearest U.S. embassy or consulate. Many embassies offer notarial services for U.S. citizens[reference:26].
- Prepare the affidavit. Download or draft the affidavit before your appointment. Do not sign it—you must sign it in the presence of the consular officer.
- Bring your U.S. passport. You will need to present valid identification.
- Sign the affidavit before the consular officer. The officer will notarize your signature and affix the embassy's seal.
- Check if an apostille is needed. Documents notarized at a U.S. embassy abroad do not receive a state apostille. Instead, they are authenticated by the U.S. Department of State. However, many foreign authorities accept the embassy's seal directly. Confirm with the local civil registry whether additional authentication is required.
Authentication and Apostille Requirements
For your document to be accepted by a foreign government, it must be properly authenticated. The process depends on where the document was issued.
For state-issued documents (Certificate of No Record of Marriage or notarized affidavit):
- You must obtain an apostille from the Secretary of State of the state where the document was issued or where the notary is commissioned[reference:27].
- This apostille certifies the official's signature and seal, making the document legally recognizable in all countries that are members of the Hague Apostille Convention.
- Processing times for state apostilles vary, typically ranging from 1 to 4 weeks by mail, or 1 to 5 days if you use a courier service or walk‑in service.
For documents notarized at a U.S. embassy or consulate abroad:
- These documents are not eligible for a state apostille. Instead, they may need to be authenticated by the U.S. Department of State's Office of Authentications.
- However, in many cases, the foreign authority will accept the document with the embassy's seal alone[reference:28]. Always check with the local civil registry.
Translation: Many countries require the document to be translated into their official language. Use a certified translator and include a notarized statement of accuracy.
Estimated Fees, Processing Times, and Expedited Options
The table below provides a general overview of typical costs and timelines as of July 2026. Actual amounts and times vary by state and service provider.
| Step | Estimated Cost | Estimated Time |
|---|---|---|
| Certificate of No Record (County/State) | $10 – $30 | 1 – 4 weeks (depending on office) |
| Notary Public (Affidavit) | $5 – $25 | Same day |
| Apostille (Secretary of State) | $5 – $20 | 1 – 4 weeks (mail) / 1–5 days (walk‑in or courier) |
| Translation (if required) | $25 – $50 per page | 2 – 5 business days |
| Total (State Document + Apostille + Translation) | $40 – $100+ | 2 – 8 weeks |
If you are on a tight timeline, consider using a professional apostille service that can expedite the process[reference:29]. These services handle the document preparation, notarization, and routing through the Secretary of State, often reducing the total time to 1–2 weeks.
Common Mistakes That Can Delay Your Marriage Plans
Even a small error can derail your plans to marry abroad. Avoid these frequent pitfalls.
- Assuming the U.S. government issues a Certificate of No Impediment. It does not[reference:30]. You must create a substitute document—either a state‑issued Certificate of No Record of Marriage or a notarized Single Status Affidavit.
- Submitting the wrong document type. Some countries require a state‑issued certificate, while others accept a notarized affidavit[reference:31]. Verify the specific requirement with the foreign embassy before you begin.
- Failing to obtain an apostille. An un‑apostilled document is not legally valid abroad in most cases[reference:32]. Without the apostille, the foreign authority cannot verify the authenticity of your document.
- Not including divorce or death certificates. If you were previously married, you must provide certified copies of your divorce decree or your previous spouse's death certificate. These must also be apostilled and translated if required.
- Signing the affidavit before the notary. Always sign in the presence of the notary or consular officer. Signing beforehand invalidates the notarization.
- Waiting until the last minute. The combined timeline for obtaining the certificate, apostille, and translation can take 2–8 weeks. Start the process at least 3 months before your planned wedding date.
- Ignoring translation requirements. Even if the officer speaks English, many countries legally require a certified translation. Check with the embassy.

Frequently Asked Questions
Q: Does the U.S. government issue a Certificate of No Impediment to Marriage?
A: No. The United States does not have a federal authority that issues this document[reference:33]. Instead, U.S. citizens must obtain a state‑issued Certificate of No Record of Marriage or a notarized Single Status Affidavit, which is then apostilled for international use[reference:34].
Q: What is the difference between a Single Status Affidavit and a Certificate of No Record of Marriage?
A: A Certificate of No Record of Marriage is an official document issued by a state or county vital records office confirming that no marriage record exists for you[reference:35]. A Single Status Affidavit is a sworn statement that you draft yourself, declaring that you are unmarried and legally free to marry[reference:36]. Both can be used, but some countries prefer the state‑issued certificate.
Q: Where do I get a Certificate of No Record of Marriage?
A: You must request it from the vital records office or county clerk in the state where you reside or where you were married (if applicable)[reference:37]. Not all states issue this document, so you may need to use a Single Status Affidavit instead.
Q: Do I need an apostille for my Single Status Affidavit?
A: Yes, in most cases. If you are using the document in a country that is a member of the Hague Apostille Convention, you must obtain an apostille from the Secretary of State of the state where the notary is commissioned[reference:38]. Without the apostille, the foreign authority will not accept the document.
Q: Can I get a Certificate of No Impediment at a U.S. embassy abroad?
A: U.S. embassies and consulates do not issue a Certificate of No Impediment. However, they can notarize a Single Status Affidavit, which some countries accept in lieu of a certificate[reference:39]. Check with the local civil registry to confirm whether this is acceptable.
Q: How long is a Certificate of No Impediment valid?
A: Validity periods are set by the receiving country, not by the U.S. Typically, the document is valid for 3 to 6 months from the date of issuance. Some countries require the document to be issued within 30 days of the marriage. Always check with the embassy or civil registry.
Q: What if I have been divorced or widowed?
A: You must provide certified copies of your divorce decree(s) or your previous spouse's death certificate. These documents must also be apostilled and translated if required. Your Single Status Affidavit should clearly state your current marital status and include the date your previous marriage ended[reference:40].
