Once a creditor is notified about the filing of your bankruptcy petition, they will have to stop all efforts of calling you from that moment onwards. The court will mail a notice to all your creditors that are listed in the schedules of the bankruptcy petition. The process of mailing will be complete, generally, within a fortnight. Your attorney could also inform them directly. If the creditors insist on continuing with their collection tactics on you after they have been notified, they will be liable to face court sanctions and will also have to pay the fees for attorneys as a result of their conduct.
