Sorry for your situation. Break ups are seldom good. Hope it all works out for you.
As far as the property stuff, I don't know if you're in the US or not, but for here I would suggest getting some sort of release done for both of you to sign, and make sure you each have a copy. Get it witnessed and so forth. A notary or lawyer would be a good idea for the witnessing.
If for no other reason, to protect yourself and your possessions. Just in case she decides to go sour on you down the road. It can happen. I've seen it over the years. Better safe than sorry in my book in any situation involving property or money, and possible hard feelings between parties somewhere along the way.
Good luck, and again, sorry for your situation. I hope things get better.
Maybe in the coming future you can sell the house and use what you get to buy something in an area you do want, and make a fresh start for yourself. :)
This is exactly what I was looking for, thanks.
I had read things that said she had no rights and that she did have rights. The constructive trust bit was very useful.
I'll definitely be getting a document sorted for that. I was thinking a family member each to sign as witness.
I feel I am doing the decent thing so I'm comfortable with that.
I'm just glad I've got parents who don't mind bailing out their kids when the shit hits the fan!
May be different here, but I very much doubt it - get it signed off legally or she can come back on you later if she starts feeling that you were unfair at some point in the future. I've had friends who thought everything was sorted fairly, to everyone's satisfaction, then a few years later a lawyers letter demanding more. Better to spend a few dollars (pounds) and be sure that cannot happen.
There's legalese stuff that if you leave it out/get it wrong on a DIY job, you basically got nothing.
Bah :( sorry to hear that!
Sounds like you've had the most useful advice already, so I'm just here with manly consolation. And drinks, if we somehow meet.
