(b) Except as provided in subdivision (a) of Section 1513.5 and subdivision (d) of Section 1516, 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 that the owner`s property will escheat to the state pursuant to this chapter. The notice shall be mailed not less than six nor more than 12 months before the time when the owner`s property held by the business becomes transferable to the Controller in accordance with this chapter. 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 bold or in a font a minimum of two points larger than the rest of the notice, (1) specify that since the date of last activity, or for the last two years, there has been no customer activity on the deposit, account, shares, or other interest; (2) identify the deposit, account, shares, or other interest by number or identifier; (3) indicate that the deposit, account, shares, or other interest is in danger of escheating to the state; and (4) specify that the California Unclaimed Property Law requires banks, banking organizations, and financial organizations 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. (c) For purposes of this section, lawful charges means charges which are specifically authorized by statute, other than the Unclaimed Property Law, or by a valid, enforceable contract.
