Hello,
I suppose your husband also posted the same query, though such agreements are not valid in the eyes of law but since your husband has admitted the liability therefore he will have to pay the same to the company (this suggestion will stand if your husband has paid something). However, if your husband has not paid something then your company is at liberty to file a lawsuit, however it can be defended well on part of your husband.
the relevant law has been laid down in VFS Global Services Pvt Ltd v. Mr. Suprit Roy, 2008 2 Bom Cr 446
