Certified copy vs notarized copy

It all depends on  the kind of documents  yo i ntend tp render as evedence in the court. Mention the documents.

A certified copy is a copy (often a photocopy) of a primary document that has on it an endorsement or certificate that it is a true copy of the primary document. ... A notarized copy is signed by a notary public (not to be confused with a notary in a civil law country).

Typically, a mere notarization does not make a document legal if it's legally deficient before it is notarized. A notary is prohibited from preparing legal documents or acting as a legal advisor unless they're also an attorney. While on the other hand, a certified copy doesn't have to be endorsed by whoever issued the original document.

In simple terms a certified copy doesn't certify that the original document is genuine or legally valid, it only verifies that it is a true copy of the original document.

Henceforth, the consideration part you're worrying about is actually based upon the courts discretion, which means that depending upon case issues, factors, etc. a court may specify whether a certified copy or a notarized copy of a document is required to be submitted.

Hope It Helps!
