Cal. Code Civ. Proc. § 1410
The Attorney General shall, from time to time, commence actions on behalf of the state for the purpose of having it adjudged that title to unclaimed property to which the state has become entitled by escheat has vested in the state, and for the purpose of having it adjudged that property has been actually abandoned or that the owner thereof has died and there is no person entitled thereto and the same has escheated and vested in the state. Such actions shall be brought in the Superior Court for the County of Sacramento; except that if any real property covered by the petition is not situated in the County of Sacramento, an action respecting the real property shall be commenced in the superior court for the county in which such real property or any part thereof is situated. The Attorney General shall cause to be recorded in the office of the county recorder of the county in which the real property is situated, a notice of the pendency of the petition containing the names of the parties, and the object of the action and a description of the property in the county affected thereby. From the time of filing such notice for record only, shall a purchaser or encumbrancer of the property affected thereby be deemed to have constructive notice of the pendency of the action, and only of the pendency against parties designated by their real names.
Such action shall be commenced by filing a petition. The provisions of Section 1420, relating to the facts to be set forth in the petition, joinder of parties and causes of action, and the provisions of Section 1423, relating to appearances and pleadings, shall be applicable to any proceeding had under this section.
Upon the filing of the petition, the court shall make an order requiring all persons interested in the property or estate to appear on a day not more than 90 days nor less than 60 days from the date of the order and show cause, if any they have, why title to the property should not vest in the State of California.
Service of process in such actions shall be made by delivery of a copy of the order, together with a copy of the petition, to each person who claims title to any property covered by the petition and who is known to the Attorney General or the Controller or who has theretofore filed in the office of the Controller a written request for such service of process, stating his name and address, including street number, or post-office box number, if any, and by publishing the order at least once a week for two consecutive weeks in a newspaper published in the county in which the action is filed, the last publication to be at least 10 days prior to the date set for the hearing.
Upon completion of the service of process, as provided in this section, the court shall have full and complete jurisdiction over the estate, the property, and the person of everyone having or claiming any interest in the property, and shall have full and complete jursidiction to hear and determine the issues therein, and to render an appropriate judgment.
In addition to the foregoing publication of the order, a notice shall be given by publication, at least once a week for two successive weeks in a newspaper published in the county from which the property was forwarded to the State Treasury or is situated, of each estate and item of property from such county or situated in such county in excess of one thousand dollars ($1,000). Such notice shall state that a petition has been filed and an order made as hereinbefore provided and shall list each estate and item in excess of one thousand dollars ($1,000) and show the amount of the property, if money, or a description thereof, if other than money, and the name of the owner or claimant and his last known address. Any omission or defect in the giving of such additional notice shall not affect the jurisdiction of the court.
If it appears from the facts found or admitted that the state is entitled to the property or any part thereof mentioned in the petition, judgment shall be rendered that title to such property or part thereof, as the case may be, has vested in the state by escheat.
No costs of suit shall be allowed against any party in any action or proceeding had under this section.
