You should ask for a copy of this. If the seller is legit that should be no problem.

Agreed, while I don't normally every file mine / did you record a copy of the contract for deed at the court house ?

For reference and others, that is why a safety deposit box is a must if you don't have a fire proof safe ( or both for some very important documents)
