A little background story, my ex had an affair with my son's soccer coach 3 years ago so she moved out. The guy has nothing to his name and my ex and I (mostly me) made a lot of good financial decisions over the years so we're both well off, I've made several attempts over the years to get her to put money into a trust for the kids where I would match her dollar for dollar with no success. I found out this weekend from my kids who live with me full time that she is getting married on Saturday and that the beat guy was pushing to get married. I called her to offer congrats then asked if she has made any financial arrangements for the kids future. She said that a pre-nuptial was signed but I'm still concerned dead beat will siphon $$. I haven't done any research into pre-nups so interested if anyone has any experiences???
