I have been living with my partner for the last 4 years in my owned home, we have decided to move into a bigger property. He sold his marital home and is prepared to put his money into buying a house with me. We are both putting the same amount of cash into our first home together. However, here's the problem.. He is still married to his wife, and no matter how many times I ask him 'when are you likely to start divorce proceedings' it goes unnoticed. I am worried that at some point his wife could ask for half of his assets, which by this time my £100k would be in a joint owned property. Would anyone know of any legal rights?
