Notarization is when a Notary Public confirms that a signature is real, the signer agreed to it, and the document is meant to be official. To get something notarized, all signers and any witnesses need to be there, and you'll need to show a valid ID and bring all pages of the document.
An apostille is a special stamp or certificate that makes a document official and recognized in another country. It confirms that the document is legitimate and that it was signed by the right person or authority. If you need to use documents like birth certificates, diplomas, or legal papers in another country, an apostille helps them be accepted there.
