Code Civ. Proc., § 1607

When a report is received from the Comptroller General or other proper officer of the United States, the Controller shall prepare and forward a copy thereof to the clerk of the superior court of each county within this state and the clerk shall post a copy at the courthouse for a period of 60 days. Any person asserting an interest in property mentioned in the report may elect to claim against the United States under the laws of the United States, in which event and within 90 days following the date of initial posting by the clerk the person shall notify the Controller of the asserted interest and intention to so claim. The Controller shall omit the property from any claim by the state until such time as the asserted interest may be finally determined against the claimant. The interest may not thereafter be asserted against the state.
