What is Signature Certification?

Signature Certification is the legal process in which a licensed lawyer verifies:

• The identity of the signer
• That the document was signed voluntarily
• That the signature was witnessed by the lawyer

Many foreign authorities require documents to be signed in the lawyer's presence before certification.
