Does Child Support lien stay on after mortgage forclosure ?

[Maugno M.]

Evening BP. Ive been eyeing a property I want that will be foreclosed at the court house steps by a trustee. I was looking at the county records and here is what I discovered.

-his wife deeded her interest on the property over to him about 9 years ago. deed reference their marriage and cause #. and in the interest of their children??

-8 years ago a lien for about 10k from child support. Lien says it attaches to any personal and real property not exempt. It says something about expiration in a certain year that has already passed

Wells fargo is the beneficiary. Looks like they have done about 3 substitute trustees throughout the years and 2 years ago, they assigned the deed of trust to another company. 

has anyone dealt with any of this ? Child support gets wiped out with the foreclosure or sticks ?
