A power of attorney is a private document. Before it can receive an apostille, it must be signed in front of a California notary using the correct notarial certificate. The apostille then authenticates the notary's signature.
If an overseas bank, attorney, or government office gave you the document, ask whether they have specific signing, witnessing, or wording requirements. An apostille authenticates the signature. It does not decide whether the document satisfies the foreign recipient's legal requirements.
We do not draft legal documents or give legal advice. For questions about what a power of attorney should say, please speak with a licensed attorney.
