20 Pa.C.S. § 783

A writ of sequestration of real or personal property of an estate or trust, or of the respondent, to enforce an order or decree of the orphans' court division in the administration of the estate or trust shall be allowed by the orphans' court division as fully as in any court of equity, and shall be directed to and executed by the sheriff of the county in which the court or branch of the court is located or of any county where property to be sequestered is located. The orphans' court division, by general rule or special order, may prescribe the practice relating to sequestration of real and personal property. To the extent not provided for by general rule or special order, the practice relating to sequestration shall conform to the practice in the division of the court having jurisdiction over actions at law.
