Code Civ. Proc., § 1520

(a) All tangible personal property located in this state and, subject to Section 1510, all intangible personal property, except property of the classes mentioned in Sections 1511, 1513, 1514, 1515, 1515.5, 1516, 1516.5, 1517, 1518, 1518.5, 1519, and 1521, including any income or increment thereon and deducting any lawful charges, that is held or owing in the ordinary course of the holder’s business and has remained unclaimed by the owner for more than three years after it became payable or distributable escheats to this state.

(b) Except as provided in subdivision (a) of Section 1513.5, subdivision (b) of Section 1514, subdivision (d) of Section 1516, and subdivisions (b) and (c) of Section 1516.5, if the holder has in its records an address for the apparent owner of property valued at fifty dollars ($50) or more, which the holder’s records do not disclose to be inaccurate, the holder shall make reasonable efforts to notify the owner by mail or, if the owner has consented to electronic notice, electronically, that the owner’s property will escheat to the state pursuant to this chapter. The notice shall be mailed not less than 6 nor more than 12 months before the time when the owner’s property held by the business becomes reportable to the Controller in accordance with this chapter. The face of the notice shall contain a heading at the top that reads as follows: “THE STATE OF CALIFORNIA REQUIRES US TO NOTIFY YOU THAT YOUR UNCLAIMED PROPERTY MAY BE TRANSFERRED TO THE STATE IF YOU DO NOT CONTACT US,” or substantially similar language. The notice required by this subdivision shall specify the time when the property will escheat and the effects of escheat, including the need to file a claim in order for the owner’s property to be returned to the owner. The notice required by this section shall, in boldface type or in a font a minimum of two points larger than the rest of the notice, exclusive of the heading, (1) specify that since the date of last activity, or for the last two years, there has been no owner activity on the deposit, account, shares, or other interest; (2) identify the deposit, account, shares, or other interest by number or identifier, which need not exceed four digits; (3) indicate that the deposit, account, shares, or other interest is in danger of escheating to the state; and (4) specify that the Unclaimed Property Law requires holders to transfer funds of a deposit, account, shares, or other interest if it has been inactive for three years. It shall also include a form, as prescribed by the Controller, by which the owner may confirm the owner’s current address. If that form is filled out, signed by the owner, and returned to the holder, it shall be deemed that the account, or other device in which the owner’s property is being held, remains currently active and recommences the escheat period. In lieu of returning the form, the holder may provide a telephone number or other electronic means to enable the owner to contact the holder. With that contact, as evidenced by a memorandum or other record on file with the holder, the account or other device in which the owner’s property is being held shall be deemed to remain currently active and shall recommence the escheat period. The holder may impose a service charge on the deposit, account, shares, or other interest for this notice in an amount not to exceed the administrative cost of mailing or electronically sending the notice and form, and in no case to exceed two dollars ($2).

(c) In addition to the notice required pursuant to subdivision (b), the holder may give additional notice as described in subdivision (b) at any time between the date of last activity by, or communication with, the owner and the date the holder transfers the property to the Controller.

(d) For purposes of this section, “lawful charges” means charges that are specifically authorized by statute, other than the Unclaimed Property Law, or by a valid, enforceable contract.
