Certified Copy
A Certified Copy is a duplicate of an original document that has been verified by the official custodian of the original record (e.g., a government agency, court, or university registrar) as a true and accurate reproduction.
Notarized Copy
A Notarized Copy typically refers to a document where a notary public has attested to the authenticity of a signature on a 'copy certification by document custodian' affidavit. In this process, the document's owner presents a copy and the original to the notary, then signs an affidavit swearing the

Our Verdict
Choosing between a certified copy and a notarized copy hinges entirely on the specific document and the requirements of the entity requesting it. For documents like birth certificates, marriage licenses, or court orders, the clear winner is a certified copy obtained directly from the issuing authority, as notaries are generally prohibited from certifying these.
Best for: Certified Copy
- Official government filings requiring vital records (e.g., birth, death, marriage certificates).
- Court proceedings where original documents or their certified duplicates are mandated.
- Academic applications requiring official transcripts from educational institutions.
- Situations where the highest level of legal authenticity from the original source is required.
Best for: Notarized Copy
- Business contracts, agreements, or records where the original's owner attests to the copy's truth.
- Power of attorney documents where a duplicate is needed and the principal can swear to its accuracy.
- Documents for foreign use where direct agency certification is impractical or a 'copy certification by document custodian' is accepted.
- Situations where a notary's verification of a signer's oath is sufficient for the recipient.
Pro Tips
- Always clarify the exact requirement with the receiving entity: ask if they need a 'certified copy from the issuing agency' or if a 'notarized copy certification by document custodian' will suffice.
- For critical documents like birth certificates or marriage licenses, assume you need an official certified copy directly from the government agency that issued it; notaries cannot typically provide these.
- If you're a mobile notary, educate your clients on the distinction, especially regarding 'copy certification by document custodian' affidavits, to manage expectations and avoid confusion.
- When preparing a 'copy certification by document custodian' affidavit, ensure the original document is present for the notary to sight, even if they aren't certifying it, as it's often a best practice and sometimes a state requirement.
- Be aware that specific agencies, like USCIS for immigration documents, often have unique requirements for copies. Review their guidelines thoroughly before seeking notarization or certification.
Frequently Asked Questions
Can a public notary certify a copy of any document?
Generally, no. Most states prohibit notaries from certifying copies of vital records (like birth certificates, marriage licenses) or public records. A notary's role is typically to attest to the identity of the person signing a document, or to the signing of a 'copy certification by document custodian' affidavit, not the authenticity of the original document itself. Always check your state's notary laws.
What is a 'copy certification by document custodian' and how does a notary assist with it?
A 'copy certification by document custodian' is an affidavit where the document's owner (custodian) swears under oath or affirmation that a copy is a true and accurate reproduction of the original. A notary's role is to verify the identity of the custodian and witness their signature on this affidavit, not to certify the copy's authenticity directly. This is a common workaround for documents notaries cannot directly certify.
When would I need a certified copy instead of a notarized copy?
You typically need a certified copy when the receiving entity (e.g., government agency, court, university) requires an official, legally binding assurance that the copy is an exact duplicate of an original document that is usually issued by a public record office. This is common for birth certificates, death certificates, academic transcripts, and court orders.
Are remote online notarization (RON) platforms able to provide certified copies?
RON platforms facilitate the notarization of documents, including 'copy certification by document custodian' affidavits, by connecting you with a remote notary. However, a RON notary, like a traditional notary, cannot issue a 'certified copy' of a vital record or public document. They can only notarize the custodian's statement about the copy's accuracy.
What's the typical cost difference between obtaining a certified copy and a notarized copy?
The cost for a certified copy is usually a fixed fee charged by the issuing agency (e.g., county clerk, vital records office), often ranging from $10-$30 per copy. A notarized copy (specifically, the notarization of a copy certification by custodian affidavit) will incur a notary fee, which is state-regulated and can range from $2-$15 per signature, plus any travel fees for mobile notaries.
Can a Notary Public in one state notarize a copy for use in another state or country?
Yes, a Notary Public can notarize a 'copy certification by document custodian' affidavit for a document, regardless of where it will be used, as long as the notarization itself complies with the laws of the state where the notary is commissioned. For international use, an Apostille or certification from the Secretary of State may also be required after notarization.
