A Pennsylvania Writ of Possession is a court order that authorizes a sheriff or constable to remove a tenant from a property if the tenant has been evicted or has not complied with the terms of their lease agreement. A Writ of Possession is issued by the court, after a landlord has successfully obtained a court order of possession. The Writ of Possession directs a sheriff or constable to evict the tenant from the property, remove their personal property, and return possession of the property to the landlord. There are two types of Writs of Possession in Pennsylvania: Summary and Formal. A Summary Writ of Possession is most often used when a tenant has failed to pay rent or has violated the terms of their lease agreement. A Formal Writ of Possession is used when a tenant has been in possession of the property for more than one year.
