Me and stbx agreed on terms of a sep agreement. We drew one up, and I signed and notarized it, and gave it to her to get it signed and notarized. This was a couple of months ago. She still has not signed it. Now I have learned some new information, and I would like to take back the sep. agreement. Is there any legal way for me to tell her that she must return the agreement, or destroy it? Or am I at her mercy as to whether she decides to sign it or not, and if she does then I am bound by it. I have learned new information and that first sep. agreement does not fully reflect the new information.
