Verifications Required:

  • Verification of property/assets (checking, savings, IRA or retirement account statements, car registration(s), land owned, etc.)

Welfare Fraud:

The Special Investigations Unit (SIU) is responsible for maintaining the integrity of public assistance programs. Welfare fraud investigators are charged with deterring, detecting and prosecuting fraud. This ensures that our programs are available for those in need of assistance. Referrals are received from the community, automated detection systems, eligibility staff and other agencies, hotlines, etc. All referrals are investigated, and the caller may remain anonymous. We have a bilingual speaking investigator available for Spanish referrals and assisting in translations.

SIU also contains the Collections Unit, which is responsible for billing and collecting overpayments due to administrative errors, client caused errors, and intentional program violations. Marin participates in the Tax Intercept Program which enables our Department to collect money from clients that are not paying by intercepting their tax returns.

To report suspected fraud for CalWORKs, CalFresh, General Assistance or In-Home Support Services (IHSS) please call (415) 473-7071 or fax (415) 473-7166.
