Financial Fraud Investigations

Our financial fraud team includes forensic accountants, a Certified Fraud Examiner, and former federal financial-crimes investigators, including IRS Criminal Investigation experience. We investigate embezzlement, Ponzi and pyramid schemes, wire and bank fraud, money laundering, and misappropriation of funds. Where assets have been hidden or moved, our years of experience in the intelligence community enable us to trace them across jurisdictions and countries including offshore companies and trusts while working within the relevant laws and procedures. Findings are organized into clear, well-documented reports suitable for settlement negotiations, expert testimony, or referral to the appropriate authorities.

Due Diligence Investigations

Legal matters and transactions alike depend on knowing exactly who you are dealing with. ASIG conducts due diligence investigations on opposing parties, witnesses, experts, business partners, and acquisition targets by verifying backgrounds, corporate records, litigation history, regulatory standing, and undisclosed affiliations. Using professional databases not accessible to the public, combined with human-source inquiries, we surface the facts that change strategy: prior misconduct, concealed relationships, financial distress, or credibility issues. Attorneys rely on our due diligence work for vetting, discovery planning, and pre-litigation risk assessment.

ASIG maintains chain of custody on every item we collect, whether physical documents or extracted digital data and hosts digital evidence in a technically sound manner to preserve authentication.
