Surveillance — Marietta and Cobb County
Surveillance in Marietta covers the Marietta Square area, East Cobb corridors along Johnson Ferry Road and Roswell Road, the Cumberland and Akers Mill areas near I-285, and residential neighborhoods throughout the city and unincorporated Cobb County. Investigators work from legally permissible public positions, recording activity with timestamped video and a written log formatted for court use.
Subjects in Marietta frequently commute between Cobb County, Atlanta, and other metro locations during work hours. Familiarity with the I-75, I-285, and Barrett Parkway corridors is operationally necessary for effective mobile surveillance in this area. Two-investigator teams are available where detection risk is elevated.
Child Custody Investigation — Cobb County Superior Court
Custody investigations for Marietta residents produce evidence for Cobb County Superior Court's Family Division under the best-interest standard of O.C.G.A. § 19-9-3. Documented PI evidence of a parent's conduct, living situation, and activities addresses the court's 17 statutory factors directly. Custody modification proceedings require demonstrating a material change in circumstances — PI surveillance documentation supports that threshold more effectively than a parent's personal testimony alone.
Background Checks and Litigation Support — Cobb County Attorneys
Litigation support for Marietta and Cobb County attorneys includes subject location, asset investigation, witness location, and process service. Background investigation covers Cobb County courthouse records, multi-jurisdiction criminal and civil history, and national database research. Reports are delivered in formats ready for attorney use within agreed timelines.
