An affidavit is generally a written statement of facts that the signer declares to be true under oath or affirmation. Affidavits are used in many settings, including litigation, property matters, financial transactions, identity matters, business disputes, insurance claims, family matters, immigration-related supporting documentation, and administrative proceedings.
The notary does not determine whether the facts in the affidavit are true. The notary's role is to perform the requested notarial act, identify the signer as required, administer an oath or affirmation when the document requires one, witness the signing when required, and complete the notarial certificate.
A signer should not ask the notary to draft the affidavit, decide what facts belong in it, or determine whether the affidavit is legally sufficient for the underlying matter.

A remote notarization of an affidavit is a notarial act. An unsworn declaration executed outside the United States under 28 U.S.C. §1746, when that pathway actually applies, is a different paper and is not a substitute for every affidavit abroad. See the §1746 guide.
