Next step
Sign by video with our New Jersey notary while you're in Maine, 7 AM to 9 PM Eastern, seven days a week, by appointment. New Jersey law lets a New Jersey notary notarize for a signer located in another state (N.J.S.A. 52:7-10.10). How Maine treats it: Maine recognizes notarial acts performed in other states: an act performed by a notary public of another state has the same effect as if a Maine notarial officer performed it. More on Maine signers.
If the agent will use it for real estate, ask the title company or the county registry of deeds before you sign.
