By law, each of us is individual entity. So filling a bankruptcy will not affect your spouse.

If you spouse is your debts guarantor, then he or she will have to responsible for it since they had legally sign to guarantee your payment to the bank.

It is similar to the case of supplementary credit card. Since they are the legal holder of the card register under their name, then they will have to responsible on the debts under their name only.

Last but not least, you bankruptcy will not affect your spouse’s credit rating as long as the unsettled debts are not register under their name.
