The automatic stay is effective upon the filing of the petition in bankruptcy whether or not the levying officer has knowledge of the bankruptcy. However, the levying officer must have notice or knowledge of the bankruptcy in order to comply with bankruptcy policies and procedures. “Notice” should be verifiable and may be in a variety of forms, such as a copy of a document issued by the bankruptcy court, a letter signed by the bankrupt or his attorney, information in an employer’s return or garnishee’s memorandum of garnishee, or verifiable oral notice. At a minimum, reasonable “notice” includes the name or location of the bankruptcy court, the approximate date of filing and the name and address under which the debtor filed the petition.
