Cal. Code Civ. Proc. § 1610
No summons or other process shall issue to direct the appearance and answer of a respondent. Commencing within five days after filing petition, notice of the proceeding shall be published once each week for three consecutive weeks in a newspaper of general circulation published within the County of Sacramento. At the time the notice is first published, a copy of the petition and notice shall be posted at the courthouse in the county where each defendant was last known or presumed to have had an address. Such petition and such notice shall remain posted for 45 days. The notice of proceeding shall advise that the State seeks custody of unclaimed property held by the United States. The names but not the addresses of the respondents shall be contained in the notice with a statement that such persons are believed to live or to have lived within the State and are believed to be or to have been owners of the unclaimed property. The notice shall not contain a description of the unclaimed property but shall advise that such description together with the last known or presumed addresses of owners may be determined by examining the petition filed in the proceeding. The petition and its place of filing shall be sufficiently identified and described. The notice shall advise that persons claiming an interest must answer the petition within the time prescribed by law, which time shall be stated, if they elect to pursue their claims against the United States, otherwise their rights to property shall be preserved subject to delayed delivery as provided by law. The notice shall advise that Section 1611, Code of Civil Procedure, should be consulted for the time, form, and costs of an answer.
The notice shall be deemed completed 45 days after the date of first publication, whereupon the court shall have full and complete jurisdiction over the property described in the petition and not claimed within the time or in the manner provided in Section 1611, and shall have full and complete jurisdiction to determine the right of the State to custody and to render an appropriate judgment therefor.
