First of all, apologies if this has been asked before many times before!
DP and I have been together about 10 years, lived together about 5. The house/mortgage is all in his name because at the time we got it I had no savings to put towards a deposit and wouldn't have been able to get a mortgage as I had no regular income (I was a full-time student at the time). Since we moved in I've paid half of the mortgage and all other costs like bills, council tax, insurance etc - I give him the money every month and he pays everything as it's all in his name. We don't have any agreement in writing, this is just what we informally agreed to do.
This works fine, but the question is what would happen if we were to split up, or if he were to die - i.e. do I have any legal rights to any share of the house? I think I probably don't, he thinks maybe I do as we're living together 'as though we're married' and I can prove that I've given him regular payments every month which correspond to half his mortgage payments. But Ithink I have fewer rights even than a tenant in a rental property (as there's no contract or written agreement), and if he decided to kick me out and change the locks tomorrow (he wouldn't, but hypothetically!) there would be nothing I could do about it. I know there's no such thing as common-law marriage.
Do I need to make sure we get this all written down and official? Or should we just get married?
