Does a Maine purchase and sale agreement have to be notarized?

[Allison Meggison]

I have searched through many forums and seen different responses; None of which answer my question. My question is this: When I get a purchase and sale agreement signed does it have to be notarized right then and there ? (In Maine*) I know I have to send/take the contract to escrow but I don’t understand why or how a notary would

Come into play since we are going to the title agency anyway
