Seller child support lein

[Spencer I.]

I have a property under contract ($31k) with 9 heirs, one of them has a child support lein for about $55k. Is there a way for this heir to relinquish his rights to the property so we can wholesale it? I have a buyer ready at $37k,  but we don't know how to get around the child support lein. They want it paid in full before the sell. Any and all suggestions welcome.
