Expert Services from a Private Investigator in Beverly Hills
Whether your matter involves protecting your family, safeguarding your business, or supporting your legal case, our agency delivers clear answers and verifiable evidence. From the luxury storefronts along Rodeo Drive to the quiet gated neighborhoods in the hills, our investigators have helped clients uncover hidden truths, resolve disputes, and secure peace of mind.
We’re more than just a detective agency near you; we’re a professional resource you can depend on when the stakes are high. Below are some of the key areas where our private investigation services provide critical support:
Support for Labor & Employment Law
The fast-paced business world of Beverly Hills often leads to workplace disputes that demand objective investigation. Our private detectives and investigators partner with employment attorneys to strengthen cases involving:
  • Wage-and-hour conflicts, including unpaid overtime or withheld wages.
  • Discrimination or harassment complaints.
  • Unsafe or hostile work environment claims.
Our approach includes interviewing witnesses, reviewing financial records, and delivering court-ready documentation. By gathering verifiable evidence, we give employees a voice and empower attorneys with the solid proof needed to pursue justice effectively.
Asset & Financial Investigations
In Beverly Hills, where wealth and assets are often layered under complex structures, uncovering financial truth can be vital. Our private investigation agency specializes in identifying hidden or undisclosed holdings. We locate:
  • Real estate, vehicles, and luxury assets are not reported.
  • Secret partnerships, shell companies, or offshore accounts.
  • Liabilities, debts, or encumbrances that may alter the outcome of negotiations or legal battles.
With our findings, clients and their legal teams gain the clarity required to make informed, strategic decisions.
Surveillance & Injury Claim Verification
Insurance fraud and exaggerated claims can cost businesses and individuals millions each year. Our investigators discreetly document activities to validate or challenge injury and workers’ compensation claims. Through advanced surveillance technology, we capture video, photography, and behavioral evidence to confirm whether reported injuries match observed activity. This service protects insurance providers, employers, and legal professionals from fraudulent losses.
Legal Document Service & Support
Serving subpoenas and court papers in Beverly Hills can be particularly challenging when subjects go to great lengths to remain hidden. Our private investigator firm uses meticulous planning, stakeouts, and strategic timing to guarantee documents are delivered properly. By combining local expertise with persistence, we keep your legal process on track without costly delays.
Probate & Estate Investigations
Attorneys handling estate matters often rely on us to locate heirs, confirm family relationships, or track down missing beneficiaries. Using international databases, genealogy research, and direct fieldwork, our investigators provide clear and defensible reports that verify family ties. This ensures assets are distributed lawfully and minimizes the risk of disputes among beneficiaries.
Personal Injury & Accident Investigations
When an accident occurs in Beverly Hills, swift evidence gathering is essential. Our investigators quickly secure surveillance footage, photograph scenes, and interview witnesses to reconstruct the event timeline. This fast action strengthens injury claims and provides victims with the best possible chance of achieving rightful compensation.
