Plans to acquire property accelerated by early passing.

Hi y'all,

Original plan was for my condo to be purchased by me in a few years, but we made no contracts or legally binding agreements. We weren't aware at time of purchase that I could have been put on the title as part-owner.

My friend passed away, the wife intends to proceed with the plans. But how do we proceed a) until/during the succession process? and b) what can I do to secure my position legally with this property? c) what are the different options I have as far as taking over the mortgage, getting title, etc. d) what kind of real estate professional(s) should I talk to?

Looking forward to as much help as possible. Looking to the BP community for sincere responses from people with integrity, knowledge and experience!
