Cal. Civ. Proc. Code § 1514

(a) The contents of, or the proceeds of sale of the contents of, any safe deposit box or any other safekeeping repository, held in this state by a business association, escheat to this state if unclaimed by the owner for more than three years from the date on which the lease or rental period on the box or other repository expired, or from the date of termination of any agreement because of which the box or other repository was furnished to the owner without cost, whichever last occurs.
(b) If a business association has in its records an address for an apparent owner of the contents of, or the proceeds of sale of the contents of, a safe deposit box or other safekeeping repository described in subdivision (a), and the records of the business association do not disclose the address to be inaccurate, the business association shall make reasonable efforts to notify the owner by mail, or, if the owner has consented to electronic notice, electronically, that the owner’s contents, or the proceeds of the sale of the contents, will escheat to the state pursuant to this section. The business association shall give notice not less than 6 months and not more than 12 months before the time the contents, or the proceeds of the sale of the contents, become reportable to the Controller in accordance with this chapter.
(c) 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 date that the property will escheat and the effects of escheat, including the necessity for filing a claim for the return of the property. 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, do all of the following:
1. (1) Identify the safe deposit box or other safekeeping repository by number or identifier.
2. (2) State that the lease or rental period on the box or repository has expired or the agreement has terminated.
3. (3) Indicate that the contents of, or the proceeds of sale of the contents of, the safe deposit box or other safekeeping repository will escheat to the state unless the owner requests the contents or their proceeds.
4. (4) Specify that the Unclaimed Property Law requires business associations to transfer the contents of, or the proceeds of sale of the contents of, a safe deposit box or other safekeeping repository to the Controller if they remain unclaimed for more than three years.
5. (5) Advise the owner to make arrangements with the business association to either obtain possession of the contents of, or the proceeds of sale of the contents of, the safe deposit box or other safekeeping repository, or enter into a new agreement with the business association to establish a leasing or rental arrangement. If an owner fails to establish such an arrangement prior to the end of the period described in subdivision (a), the contents or proceeds shall escheat to this state.
(d) In addition to the notice required pursuant to subdivision (b), the business association may give additional notice in accordance with subdivision (c) at any time between the date on which the lease or rental period for the safe deposit box or repository expired, or from the date of the termination of any agreement, through which the box or other repository was furnished to the owner without cost, whichever is earlier, and the date the business association transfers the contents of, or the proceeds of sale of the contents of, the safe deposit box or other safekeeping repository to the Controller.
(e) The contents of, or the proceeds of sale of the contents of, a safe deposit box or other safekeeping repository shall not escheat to the state if, as of June 30 or the fiscal yearend next preceding the date on which a report is required to be filed under Section 1530, the owner has owned, with a banking organization providing the safe deposit box or other safekeeping repository, any demand, savings, or matured time deposit, or account subject to a negotiable order of withdrawal, which has not escheated under Section 1513 and is not reportable under subdivision (d) of Section 1530.
(f) The contents of, or the proceeds of sale of the contents of, a safe deposit box or other safekeeping repository shall not escheat to the state if, as of June 30 or the fiscal yearend next preceding the date on which a report is required to be filed under Section 1530, the owner has owned, with a financial organization providing the safe deposit box or other safekeeping repository, any demand, savings, or matured time deposit, or matured investment certificate, or account subject to a negotiable order of withdrawal, or other interest in a financial organization or any deposit made therewith, and any interest or dividends thereon, which has not escheated under Section 1513 and is not reportable under subdivision (d) of Section 1530.
(g) The contents of, or the proceeds of sale of the contents of, a safe deposit box or other safekeeping repository shall not escheat to the state if, as of June 30 or the fiscal yearend next preceding the date on which a report is required to be filed under Section 1530, the owner has owned, with a banking or financial organization providing the safe deposit box or other safekeeping repository, any funds in an individual retirement account or under a retirement plan for self-employed individuals or similar account or plan pursuant to the internal revenue laws of the United States or the income tax laws of this state, which has not escheated under Section 1513 and is not reportable under subdivision (d) of Section 1530.
(h) In the event the owner is in default under the safe deposit box or other safekeeping repository agreement and the owner has owned any demand, savings, or matured time deposit, account, or plan described in subdivision (e), (f), or (g), the banking or financial organization may pay or deliver the contents of, or the proceeds of sale of the contents of, the safe deposit box or other safekeeping repository to the owner after deducting any amount due and payable from those proceeds under that agreement. Upon making that payment or delivery under this subdivision, the banking or financial organization shall be relieved of all liability to the extent of the value of those contents or proceeds.
(i) For new accounts opened for a safe deposit box or other safekeeping repository with a business association on and after January 1, 2011, the business association shall provide a written notice to the person leasing the safe deposit box or safekeeping repository informing the person that his or her property, or the proceeds of sale of the property, may be transferred to the appropriate state upon running of the time period specified by state law from the date the lease or rental period on the safe deposit box or repository expired, or from the date of termination of any agreement because of which the box or other repository was furnished to the owner without cost, whichever is earlier.
(j) A business association may directly escheat the contents of a safe deposit box or other safekeeping repository without exercising its rights under Article 2 (commencing with Section 1630) of Chapter 17 of Division 1 of the Financial Code.
