California Code, Civil Code - CIV § 1812.700

(a) In addition to the requirements imposed by Article 2 (commencing with Section 1788.10) of Title 1.6C, third-party debt collectors subject to the federal Fair Debt Collection Practices Act (15 U.S.C. Sec. 1692 et seq.) shall provide a notice to debtors that shall include the following description of debtor rights:

“The state Rosenthal Fair Debt Collection Practices Act and the federal Fair Debt Collection Practices Act require that, except under unusual circumstances, collectors may not contact you before 8 a.m. or after 9 p.m. They may not harass you by using threats of violence or arrest or by using obscene language. Collectors may not use false or misleading statements or call you at work if they know or have reason to know that you may not receive personal calls at work. For the most part, collectors may not tell another person, other than your attorney or spouse, about your debt. Collectors may contact another person to confirm your location or enforce a judgment. For more information about debt collection activities, you may contact the Federal Trade Commission at 1-877-FTC-HELP or www.ftc.gov.”

(b) The notice shall be included with the first written notice initially addressed to a California address of a debtor in connection with collecting the debt by the third-party debt collector.

(c) If a language other than English is principally used by the third-party debt collector in the initial oral contact with the debtor, a notice shall be provided to the debtor in that language within five working days.
