When Joe meets his decreed obligation of alimony payments, is Jane legally required to sign a satisfaction for Joe?

You should sign.  Not all attorneys require you to have a notary witness your signature.  If you were provided the form by an attorney, you can go to the office and they will have a notary.  Or, your bank will usually have one.  If that does not work, sign and return to the attorney and see if he/she insists on notarization.    DONNA R.
