In a house with shared ownership, if one person moves out and the other assumes mortgage, how do we determine who owns what share in the end?
The answer is "it depends".  What does it depend on? If it's a breakup situation, good luck. Whatever you do, get this issue settled as quickly as possible. In the future, don't make significant purchases with people unless you have a written contract or you are married.
