Verify simulated injury and undeclared work.
Child custody & welfare
Document the child's living conditions for family court.
Corporate & internal theft
Identify losses and the people behind them.
Missing persons
Locate relatives, debtors, and lost contacts.
Background & asset checks
Solvency, employment, and property verification.
Harassment & stalking
Evidence to protect victims and support restraining orders — documented incidents your lawyer can act on.
