Forms with Public Notary Seals must be signed at the office of the Public Notary, by everyone concerned. Also important to keep in mind, is that everyone concerned should have a completed copy of the legal form unless it is a Last Will and Testament, or something to that effect. Again, an Attorney is usually not required for Standard Legal Forms, and there's no written law which requires that forms are written in a manner that only Attorneys or Lawyers can understand. That is a myth which many people simply aren't aware of. Here's a good rule of thumb to keep in mind .
Chances are, if it's witnessed and signed by all concerned - then it's probably legal.
It's a simple matter of getting an Attorney to look over the form, which generally only requires a few minutes or so - followed by a verbal approval, or disapproval.
