Judgments are generally enforceable while post-trial motions are pending unless the court orders otherwise. Thereafter, if the judgment is appealed, a federal court will stay execution if a bond is posted, unless the order was for an injunction or receivership. In California state court, subject to numerous exceptions, enforcement of the trial court judgment is automatically stayed with the timely filing of a notice of appeal. However, enforcement of certain judgments (eg, for money, sale of real or personal property, appointment of a receiver) will be stayed only if trial court so orders or if an undertaking is provided. The California appellate court may also issue a stay.

On the other hand, occasionally I feel a bit sad, knowing that after the bar, I'll never know this much law in this many areas ever again. It's like preemptive nostalgia.
