Rule 8004. Service of the Notice of Appeal
The clerk shall serve notice of the filing of a notice of appeal by mailing a copy thereof to counsel of record of each party other than the appellant or, if a party is not represented by counsel, to the party’s last known address. Failure to serve notice shall not affect the validity of the appeal. The clerk shall note on each copy served the date of the filing of the notice of appeal and shall note in the docket the names of the parties to whom copies are mailed and the date of the mailing. The clerk shall forthwith transmit to the United States trustee a copy of the notice of appeal, but failure to transmit such notice shall not affect the validity of the appeal.
