The borrower SHOULD know the legal description to their property. If they don't, they can check their tax bill or boundary survey.
As a notary, you don't care if it's the correct one. It's title's responsibility to ensure it is correct. From the notary's viewpoint, it just needs to be there or the notary cannot perform the notarization (in many states). FL statutes 117.107(10) explicitly states "A notary public many not notarize a signature on a document if the document is incomplete or blank."
