An order for relief is the event that marks the beginning of a bankruptcy proceeding, the date of which affects other matters, such as what claims are administered in the proceeding. In a voluntary case, the filing of the petition constitutes an order for relief. BRA s301. In an involuntary case, if the petition is not timely controverted, the court must enter an order for relief; otherwise, the court may enter an order for relief only on specified grounds. BRA s303.
