Three Owners, Two Want to Sell to Third Owner

[sheryl]

My question involves real estate located in the State of: RI
I own a home in RI with my brother and sister. My sister and I want to sell the home and my brother said he'd buy us out.
My first question is, is there a form for this type of sale?
Second, there is still a mortgage on the home. Does my brother have to pay off the mortgage before paying my sister and me?
My brother is in the process of trying to secure a new mortgage if for some reason he can't get one and decides he's not buying us out, how would my sister and I go about getting out of the ownership of the home?

In whose name is the mortgage loan?
