@heather-marco let's try to frame up the liability with some numbers. While I would also encourage seeing a lawyer, this would be a 'worst case' scenario. Please enter the correct numbers.
First, the mortgage has nothing to do with this. leave it out of the equation.
If you could post these numbers, I can show you how this works:
1) original percentage ownership for you and your sisiter and mother.
2) what was the purchase price?
3) what was the sum of any improvements during the owernship of the property?
4) what was the sales price?
5) what were the selling expenses (think the commission)
6) what was the property worth on the day your mom passed? did you have an appraisel done?
from that I can piece this together.
