Private Investigation Services in Oakland
Hiring a private detective company in Oakland means working with professionals who understand the Bay Area in detail and have decades of proven experience. Tristar Investigation’s licensed investigators assist attorneys, private citizens, and businesses with a wide range of cases. Here are the main areas where our investigations bring results:
Employment & Labor Law Support
Oakland’s diverse workforce makes workplace rights an important focus. Our investigators assist employment lawyers with cases involving unpaid wages, workplace discrimination, and unsafe job conditions.
We collect strong, court-ready evidence that helps attorneys build solid arguments while allowing employees to claim the justice they deserve.
Asset & Financial Investigations
Before you settle a lawsuit or pursue legal action, it’s important to know whether the other party has the means to meet financial obligations. Our private investigators in Oakland, CA, conduct in-depth asset searches across the Bay Area. These searches often uncover:
- Hidden bank accounts, properties, or vehicles.
- Undisclosed investments or business interests.
- Existing debts or financial obligations that affect recovery.
With this information, clients and attorneys can make informed decisions and protect their financial interests.
Surveillance & Injury Claim Verification
Many defense attorneys turn to us for surveillance services to confirm the accuracy of personal injury and workers’ compensation claims. Through discreet video monitoring, we reveal fraudulent or exaggerated claims that could otherwise cost employers and insurers large sums of money.
Serving legal documents is not always easy, especially when people try to avoid being found. Our team researches addresses, confirms vehicle ownership, and conducts stakeouts until papers are served. This ensures legal cases move forward without unnecessary delays.
Estate & Probate Investigations
Probate attorneys in Oakland rely on us to locate heirs and confirm family relationships. Our detailed heir searches and reports help estates get distributed fairly and reduce the chances of legal disputes.
Accident & Personal Injury Investigations
Quick action after an accident can make the difference in a legal claim. Our investigators gather on-scene evidence, locate video recordings, and take detailed witness statements. These steps provide attorneys and victims with the strong documentation they need for successful personal injury cases. |
