DP and I have decided to move in together. He will be moving in to my flat that I own by myself (I inherited the money used to buy it). I also have a decent amount in savings and own another property. My question is does he have any rights to my flat or any of my money if we split up? Both of us want to get married in the next few years, but we don't fell quite ready yet which is why we are just living together. Until we actually make that commitment I don't want him to have any rights over my money if we split up. However if I was to die I also don't want him to be slung out of my flat if we are still together (at the moment it would go to my parents). Is there any way of making him the main beneficiary of my will without it being used to try and get money out of me if we split up?
I know it sounds like I have massive doubts about this - I really don't and 99.9% trust DP to not try and claim anything if we split up. It's just that I have the idea of protecting yourself and trusting nobody when it comes to money drummed into me by my mother.
Any help much appreciated!
