But there can be a time and place where surprise is helpful. I did a post nup demanding immediate division of real estate assets as the fatm we live on was purchased with my own home as equity but later on, the farm mortgage was paid off with a large chunk of his inheritance he first had wired over and deposited to our joint account, thereby "commingling" it. Otherwise the source of those funds could have been a legal sticking point. But the idea of gifting him my old house and him gifting me the farm was brought up by a friend, and it seemed like a winner IF HE'D AGREE TO IT. As he had just been arrested for soliciting a prostitute (12 years after my first D-day about his little habit) I was 100% DONE after devoting years to trying to R and hours of MC that had clearly only prolonged my misery.
Like StillLiving, I was calling the divorce lawyer the very next day.
Lawyer drew up customized property separation papers that assigned him my old house and remaining mortgage (smallish yet I didn't have the monthly income to pay) and deeded the farm to me, free and clear of debt by that time. Lawyer wasn't sure he could do that as a post nup, once I backed down from a Separation after soft-pedalling the idea to my WH: If you want to stay M'd, would you be willing to sign an agreement gifting me this farm, and I give you the other house in exchange? WH was desperate to avoid D, so he said yes he would.
I went to the lawyer to change the Separation to a Post Nup with a tiny twinge of guilt, as my intention was still to go ahead and D him, but see how my life would change for a little while, and give him a little grace period to notice if he started doing serious work on his psychological issues, before actually "filing."
My lawyer did his homework and learned that in our state a married couple can gift property to each other as if they were separate individuals, so I asked the lawyer to draft a Marital Agreement with deeds of gift for those 2 properties and keep 1 additional, jointly-held piece of land as joint, since I hadn't financially contributed to buying it. (If we D it still is subject to Equitable distribution, I was told.)
The lawyer advised me to be sure to present the paper to him in a public place AND not to sign anything until he and then I sign it in the presence of a Notary Public.
So I picked the papers up at the lawyer's office one morning, met WH wfor lunch at an outdoor garden center, then sat down and pulled out the legal paperwork, handed it over the little bistro table apologetically and said "I hate to do this to you, but it is what we talked about." He instantly choked up, seeing the lawyer's name and the legal papers in his hand. (Even though I had said I was going to an attorney.) I think it totally blindsided him, but this was a good way to handle what could have blown up. Just as he was reading how he was surrendering his spousal rights and losing the farm he helped me pay for, along came an old couple from his men's group at church and asked how we were doing!! I almost thought I saw the angel wings on their backs!!! I feared a violent outburst or something (so did the lawyer!)
We left right from there to the County Courthouse. Did the Agreement signatures and Notarized it. Then over to a real estate attorney's office next door, as my lawyer said he didn't do that kind of work. WH asked me "What's the rush?" I said "I've waited 12 years for this moment!"
