A Practice Note explaining how to draft an application for a preliminary or special injunction in a civil case in a Pennsylvania court of common pleas, which typically includes preparing case-initiating documents, a motion, and supporting documents, such as affidavits and a memorandum of law (or brief). This Note specifically addresses how to draft a complaint and motion that support a request for preliminary injunctive relief, a proposed preliminary injunction order, a supporting brief, and other documents that should accompany the motion filing. This Note also discusses the specific requirements that apply when drafting a motion for an ex parte preliminary injunction (that is, a preliminary injunction obtained without notice to the opposing party).
