Yes, he can file without his co-signer but he should list his ex on Schedule H and identify the debts they share. He should make sure that she gets notice of his bankruptcy, because it is likely that the creditors will come after her next. From your description, he should have no problem discharging his responsibility on those debts, but his filing will not relieve his ex of her responsibility on those debts. She may need to file bankruptcy too, depending on how big the debts are. She cannot file jointly with him because they are no longer married. She would have to file her own case if she decides to go that route.
