Cal. Welf. and Inst. Code § 11157.5
The receipt of aid under Chapter 2 (commencing with Section 11200) shall not impose any limitation or restriction upon a recipient's right to sell, exchange, or change, the form of property holdings. However, a gift or any other transfer of assets, including income and resources, by a recipient for less than fair market value shall result in a period of ineligibility for aid under Chapter 2 (commencing with Section 11200) for the number of months, rounded down to the nearest whole number, that equals the quotient of the difference between the fair market value of the asset and the amount received for the asset divided by the standard of need applicable to the family under Section 11452. This section shall only apply to transfer of income or resources that would otherwise affect a recipient's eligibility for benefits or the amount of benefits to which he or she would be entitled.
