  • Hidden bank accounts, properties, and real estate holdings.
  • Undisclosed business ties and concealed investments.
  • Debts or liabilities that can affect a judgment.
By exposing these assets, we help clients and counsel make informed decisions and protect financial interests.

Using advanced methods, we capture photo and video evidence to determine whether daily activities match reported injuries—saving insurers and defense lawyers time and resources while promoting fairness.

Serving documents in Irvine can be difficult when someone avoids service. We use focused tactics, stakeouts, background research, and precise timing to deliver subpoenas and court papers properly.
