His Dad Passed away and was behind on mortgage

[Derek Tellier]

I know some of you have some experience dealing with these situations so figured I'd put this out there. 

The Situation is that a former co-worker passed away last week. According to his son he was about $8000 behind in mortgage payments and his estranged wife is on the loan. He is wanting to buy the house or somehow take possession. I don't have a lot of information at this time and I know the best answer is he needs an attorney but any advice on the process he should take or that I could help him take would be appreciated. 
So far I told him the first thing he needs to do is find out what's owed and how far behind it is. Then if the ex is indeed on the mortgage and if the foreclosure process has started yet. 

Thanks in advance
