Neb. Sup. Ct. R. 6-1508
When a party is entitled to have a monetary judgment or an amount determined to be due by default based upon a contract action, such party shall submit, with the order entering judgment, a statement of the principal amount due, which shall not exceed the amount sued for, showing credit for any payments and the amounts and dates thereof, and a separate computation of interest, if prayed for, to date of judgment. To such statement shall be appended an affidavit of the party or a certificate of his or her attorney showing that the party against whom judgment is sought is not a minor or incompetent person or in the military service, that such amount shown by the statement is justly due and owing, and that no part thereof has been paid except as set forth in the statement.
When a party is entitled to a monetary judgment on all other actions, such party shall adduce evidence in proof of damages. Such evidence shall be under oath unless waived by the court. Such party, in addition, shall submit an affidavit of the party or the certificate of the party's attorney that the party against whom the judgment is sought is not a minor or incompetent person or in the military service.
If further documentation, proof, or hearing is required, the court shall so notify the moving party.
