Cal. Unemployment Insurance Code § 2113

Nothing in this division shall prevent the department from accepting restitution or an acceptable arrangement for restitution, made voluntarily before the department files a criminal complaint under Section 2101 or 2102, for overpayment of benefits from any person, who has not previously claimed any right under this section, who has not been convicted of an offense under Section 2101 or 2102 within three years preceding the service under this section of a written notice of intent to file a criminal complaint and who has willfully made a false statement or representation or knowingly failed to disclose a material fact to obtain or increase any benefit under any provision of this division. The department shall by mail or personal service give the person written notice of intent to file a criminal complaint under Section 2101 or 2102 not less than 10 days prior to the filing of the criminal complaint. The department may accept restitution or an arrangement for restitution and any such acceptance shall be in lieu of any criminal action against the person, except that the department shall not be precluded from filing a criminal action against any person who defaults under an arrangement for restitution which it has accepted. For purposes of this section, no period of time during which an arrangement for restitution is in effect shall be a part of any limitation of the time for commencing a criminal action. The department shall deposit amounts received from any person under this section in the fund from which the overpayments were made.
