Sorry, might be long. Posting for traffic and brutal honesty from AIBU vipers.
I am in the process of divorcing, separated nearly 6 years, 2DC, elder doing GCSEs this summer, younger yr7. I am in a relationship with DP, who was a partner from before I married STBH. We have been friends since, I remained very close to his parents, who have always been very supportive of me and my DC. We got back together earlier this year.
We have been discussing options for moving in together at some point. He lives in my home area, I live about 40 minutes away, I moved there to live with STBXH and bought my own house local to him when we split. My job, my remaining family (aDd, DBIL, nieces, aunts uncles cousins etc) and most of my friends are in my home area. I really want to go home. There's much more there for the DC and schools are better. I am also disabled with a chronic illness which is deteriorating and the extra support would be beneficial to all of us.
MIL and FIL have raised the idea that the DC and I move in with them (DP currently lives with them for various reasons). They have a large house that would happily fit us all, and we could split expenses. They have a small mortgage remaining on the house and a few bits of work that ideally need doing over the next few years.
I trust them, and my DP, implicitly. However DP has two older half sisters, one with some contact, one who had not bothered with PIL for years (FILS child but raised by MIL). I have some concerns about particularly the latter trying to challenge for an inheritance when PIL are gone.
I don't know what the hell kind of legal agreement would be needed regarding the house if I am going to be paying half the mortgage/expenses if we move in, and how best to broach this with MIL and FIL without causing offence re their daughters. If anyone has been in this situation with multigenerational living I'd appreciate input. It's all just an idea at present and any move would need to wait for an appropriate time in the children's schooling etc.
Am I asking for trouble or could this work?
