Ex-spouse, quit claim, & bankruptcy

my husbands ex-wife didn't refi after their divorce. she was turned down for the new govenment housing relief program. now she is unemployed, facing forclosure, and filing bankruptcy (washington state). she is really pushing my husband to sign a quit claim, she says she is going to refi and needs it before she can do the refi's. (is that true) she now has bad credit (which has also hurt my husbands credit) and no job...so i don't thinlk she will be able to refi. i am leery of the reprocutions from him signing this, because i read it could be considered fraud if signing a quit claim less than a year before bankruptcy, and don't want us to get stuck in a $ bind when she file bankruptcy. should he sign a quit claim or not???
