Service of process is the way another person, often called the defendant, receives court papers and notices about a court case. The defendant must be served before the court will hear your case. Arch provides services of process and private investigation services for the legal, business, and government communities around the country. We specialize in the difficult to serve and service of evasive individuals. We'll perform an investigation to make sure we start at the best address we can find for the party to be served and send your case out for service. If successful, you'll get a detailed proof of service. Otherwise, you'll get a complimentary affidavit of due diligence.
