A: No, a signature verification certificate does not have an expiration date. However, it is recommended to check in advance with the notary office's policy.

Q: I see, thank you. What about when foreigners use a signature verification certificate?

A: When foreigners use a signature verification certificate, those without an address in Japan must submit one issued by a notary public in their home country. In this case, it is not necessary for the certificate to be issued within three months from the date of submission.
