To certify a document, you match the type of certification to what the document is and who will receive it: a notary public witnesses signatures, a government registrar issues certified copies of vital records, a state or federal office issues apostilles or authentication certificates for use abroad, and a bank issues a medallion signature guarantee for securities transfers. Picking the wrong one wastes the fee and the trip, so the first move is always a call or email to the receiving agency to confirm exactly what they will accept.
Start With What the Receiver Requires
Certification exists to satisfy whoever is going to rely on the document. A court, an immigration office, a foreign university, a bank, and a county recorder each have their own rules. Before you pay anyone, confirm three things with the receiving entity: the type of certification they want, whether they impose an age limit on it (some refuse anything older than three to six months), and any formatting or translation requirements. That one exchange is almost always faster than redoing the process.
Notarization
Notarization is the most common form of document certification in the United States and the one you’ll need for affidavits, powers of attorney, real estate deeds, and most contracts. A notary public verifies your identity using government-issued photo ID, watches you sign, and confirms you’re signing voluntarily. They then apply their seal, signature, and commission details to the document.
The notary is confirming that you are who you say you are and that you signed willingly. They are not vouching for anything the document says. A notarized contract full of false statements is still notarized.
State-set maximum fees for a standard in-person notarization typically run from $2 to $30, with most states capping fees between $5 and $15. Mobile notaries who travel to you add a separate travel charge.
Certified True Copies
A certified true copy is a photocopy someone authorized has compared against the original and confirmed matches exactly. The certifier adds a written statement, signature, and usually a stamp. This lets you submit a verified copy and keep the original safe.
Who can certify a copy depends on the state. In many states a notary public can certify copies of documents you personally own, such as a diploma, a professional license, or a contract. Some states also allow attorneys or court clerks to do it. The rules and the list of eligible officials vary, so ask locally before assuming a notary is enough.
When You Need a Vital Record
Birth certificates, death certificates, and marriage licenses are the exception nearly everyone runs into. Most states prohibit notaries from certifying copies of vital records, because a notary has no way to verify that the photocopy matches what’s on file with the government. Only the state or county registrar that holds the original record can issue a certified copy.
Contact the vital records office in the state or county where the event was recorded. Most accept requests by mail, online, or in person. You’ll usually need identifying information about the record, a completed application, a copy of your photo ID, and a fee. State registrar offices generally charge $10 to $30 per copy, with extra fees for rush service, online orders, or additional copies. Processing runs from same-day in person to several weeks by mail.
Apostilles for International Use
An apostille is a standardized certificate that authenticates a document for use in another country. It exists because of the 1961 Hague Apostille Convention, which more than 125 countries have joined.1HCCH. Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents If your destination country is a member, an apostille is all you need. No embassy visit, no consular legalization.
The apostille doesn’t certify what the document says. It certifies that the seal and signature on the document belong to an official who was authorized to sign it. It’s one government confirming to another that the signer was legitimate.
Where to Get an Apostille
Which office issues the apostille depends on the document’s origin. State-issued documents such as birth certificates, court orders, and notarized papers go through the Secretary of State’s office in the state where the document was issued. Federal documents such as FBI background checks or documents certified by a federal agency go through the U.S. Department of State’s Office of Authentications.2USAGov. Authenticate an Official Document for Use Outside the U.S.
Fees and Timing
Most Secretary of State offices charge $5 to $20 per document, with timelines that vary by state. The U.S. Department of State charges $20 per document and offers three processing tiers: standard processing takes up to five weeks from receipt; expedited processing runs seven business days for travel within two to three weeks; same-day processing by appointment is available if you’re leaving in under two weeks.3U.S. Department of State.

Authentication and Legalization for Non-Hague Countries
If your destination country has not joined the Hague Apostille Convention, the process is longer. You need an authentication certificate from the U.S. Department of State, followed by legalization at the destination country’s embassy or consulate in the United States.4U.S. Department of State.

The chain differs depending on where the document came from:
- State-issued documents: get the document authenticated by the Secretary of State in the issuing state, then submit it to the U.S. Department of State’s Office of Authentications for federal authentication, then take it to the foreign embassy or consulate for legalization.
- Federal documents: submit the original or an official certified copy with original seals and signatures directly to the Office of Authentications with Form DS-4194 and the fee, then take the resulting certificate to the foreign embassy or consulate.5U.S. Department of State. Preparing a Document for an Authentication Certificate
Consular legalization fees are set independently by each foreign embassy and range from $20 to several hundred dollars per document, with processing times from a few days to several weeks. Confirm formatting and scheduling rules with the specific embassy before you submit anything, because a missed detail can add weeks.
If the destination country requires a translation, get the document translated before submitting it for authentication. Have the translation notarized, but do not notarize the original document itself, which can invalidate it for authentication.5U.S. Department of State.

Medallion Signature Guarantees for Securities
Transferring stocks, bonds, or other securities is the situation where a notarization will be refused. Financial institutions require a medallion signature guarantee. Unlike a notary, the issuing institution confirms both your identity and your legal authority to transfer the securities, and it accepts financial liability if the signature turns out to be forged.
Only banks and financial institutions that participate in one of the recognized Medallion Signature Guarantee Programs can issue these stamps. You have to appear in person with your account documentation, and the review takes one to seven business days. If someone tells you they need a “signature guarantee” for a securities transaction, this is what they mean.
Certified Translations
Documents in a language other than English generally must be accompanied by a certified English translation when submitted to U.S. government agencies, courts, or immigration authorities. A “certified translation” doesn’t mean a notary blessed it. It means the translator has signed a statement that they are competent to translate between the languages and that the translation is true and accurate.6eCFR. 8 CFR 1003.33 – Translation of Documents The certification should include the translator’s name, signature, address, and the date.
You don’t have to be a licensed translator to certify a translation for most purposes, but the translator must genuinely be fluent in both languages. A professional service is the safer choice for immigration filings, where a poor translation can stall the case.
Remote Online Notarization
You no longer have to sit across a desk from a notary in every situation. Remote online notarization lets a notary verify your identity and witness your signature over a live video call. As of 2025, 47 states and the District of Columbia have enacted laws permitting some form of it.
Security is tighter than for in-person sessions, not looser. You’ll typically present an unexpired government-issued photo ID on camera, pass automated credential analysis that checks the ID’s security features, and answer identity-verification questions pulled from your credit and public records. The session is recorded and archived.
Interstate recognition is the catch. A document notarized remotely by a notary commissioned in one state may not be accepted in another. Federal legislation called the SECURE Notarization Act has been introduced in Congress to create national standards, but it has not been enacted.7Congress.gov. H.R.1777 – SECURE Notarization Act Until it passes, check with the receiving entity before relying on a remotely notarized document for a high-stakes transaction.
What to Bring
Whatever type of certification you need, bring the original document. Every certifying authority has to verify signatures on the original, compare it against a copy, or attach a certificate to it. If you need certified copies made, bring clean, legible photocopies rather than expecting the office to make them for you.
Bring valid, unexpired, government-issued photo ID. A driver’s license, state ID card, or U.S. passport works. The ID must show your photograph, a physical description, and your signature.
Budget for the Whole Chain
An international filing may require notarization, a state apostille, a federal authentication, consular legalization, and a certified translation. Priced separately each step looks small; totaled across several documents, the cost climbs quickly. Add them all up before you start.
How Long a Certification Stays Usable
Apostilles and most other certifications carry no printed expiration date. An apostille remains technically valid as long as the underlying document is still legally recognized. The receiving institution, though, may set its own freshness rule. Some agencies refuse to accept a certification more than three to six months old even though nothing about the certification itself has expired. Immigration authorities and foreign universities are especially strict on this point, so ask before you pay.
