Before I got married my husband agreed to sign a pre nup, both had our own houses, he moved in with me. I didn't think anything of it, too blinded by the wedding etc, it didn't happen. now, three children later, it's not going as we hoped, he's moved out of "my" house.... time has passed, he's realised what he's lost, wants to come back, leaving me to pay the mortgage, provide child care, run a house etc, I'm aware "post nups" are available, but in the UK are they worth the paper they are written on and what's the cost involved? Want to cover myself before I let him back, If nothing else I want to protect my house against him remarrying and passing anything that's really mine, to anyone else. I've always paid the mortgage, bills, done majority of the child care so he doesn't have any reason for a fifty fifty split (hence I suspect him wanting to come back) but complicated and long winded but any advice would be appreciated. Haven't started divorce proceedings yet on either sides
