Process Service
Process service is the formal delivery of legal documents to individuals or entities involved in court proceedings. These documents may include summonses, complaints, subpoenas, writs, divorce papers, or restraining orders. Service of process ensures due process by legally notifying the recipient of their obligation or rights to appear in court or respond to legal action. Without proper service, a case may be delayed or dismissed — making our role essential in the legal process.
