I and my partner living together nearly 13 years now. He bought the land we are currently living in. we have 3 kids. He was doing business in the same property. it is quite a big land. I moved here as he was telling me that I also have an interest inland. I contributed financially and non-finacilay to the development of the land and the business. I even signed as a guarantor for the mortgage he took to develop business. He got bankrupt and now we have a trustee in bankruptcy. We don't want to leave the land because I believe that I can claim equitable interest on the property. What we can do? Will my guarantee thing affect my claim? Is any case law similar to my situation? What interest I can claim?
