Before preparing notarization, identify who signs the declaration and who attends the notary office. The customer ordering a translation is not automatically the signatory.
Confirm the authentication method
Send the recipient's instructions, draft documents and details of the signatory and attendee to the notary office. Japan National Notaries Association guidance distinguishes signing in person, acknowledging a signature and authentication through an agent. Some methods, including sworn authentication, require personal attendance.
Documents to discuss with the notary
- Individual signatory attending: the document, identification and any required seal.
- Agent for an individual: the document, authorization and seal certificate from the signatory, and the agent's identification.
- Corporate signatory or agent: additional evidence of corporate registration and authority, as applicable.
Confirm originals, validity periods, copies and acceptable identification with the office. See the Tokyo notaries' document checklist.
Samples
Declaration sample (Word, Japanese) and individual authorization sample (PDF, Japanese). Confirm the form and signatory before signing. If a translator's authorization is requested, first clarify whose signature is being authenticated.
