Stronger Cases Start With Better Facts
Attorneys outsource research and information gathering to private investigators, allowing them to focus and properly prepare for their court date. Strategic Investigations and Security provides attorney investigation services in New York City and surrounding areas for law firms and solo practitioners, from criminal defense and family law to insurance defense, personal injury, estates and commercial litigation. Our professionally handled investigations supplement the attorney's legal work.
A thorough and accurate background check can reveal vital information on clients or defendants in local, state or federal criminal cases. We locate the key witness who cannot be found or the defendant who needs to be served, identify missing or unknown heirs, and provide surveillance and evidence for family law and insurance matters. Findings are documented in clear reports for counsel to evaluate. Our investigators provide investigative services and do not give legal advice.
Attorney support draws on our full range of private investigations: background checks, asset searches, surveillance, missing persons and corporate investigations, plus TSCM bug sweeps for law offices and meeting rooms. Every matter starts with a free, confidential consultation.
