Hello and thank you for your question. I will be very pleased to assist you. I'm a practicing lawyer in England with over 10 years experience.
May I ask the nature of the relationship between party 1 (who lives in the property) and party 2 please?
Did the parties enter into any form of declaration of trust or other form of agreement as to how they would own equity in the property?
Is there or has the been a mortgage on the property?
