Father in Law wants to quitclaim to me

[Joe Derobertis]

Hey all,

When my wife and I bought our house 4 years ago we had my father in law consign to make sure we would qualify. He's also on the title I believe. Now he wants to quit claim it to us so he's not on the title anymore. 

My question is what is the best way to do this so our mortgage company doesn't call the loan due. Should I call them and explain and get some kind of written approval from them?

Any advice?
