If your judgment included money damages for non-payment of rent the tenant would have been required to place those damages in escrow as a prerequisite to perfecting their appeal (unless they were more than three months behind, in which case their bond would be no more than three months rent). Further, while the appeal is pending the tenant is required to continue paying a sum equal to the rent every 30 days. If they fail to do so you will be able to file a praecipe to terminate the supersedeas. Once the supersedeas is removed, you would be able to have the sheriff execute on your writ of possession.
If the tenant pays the initial bond, and continues to pay an amount equal to rent every 30 days, the court, upon application, will release to you appropriate sums from the escrow account in light of the tenant's continued possession and use of your property.
