Cal. Civ. Code § 2966
(a) In a transaction regulated by this article, which includes a balloon payment note when the term for repayment is for a period in excess of one year, the holder of the note shall, not less than 90 nor more than 150 days before the balloon payment is due, deliver or mail by first-class mail, with a certificate of mailing obtained from the United States Postal Service, to the trustor, or his or her successor in interest, at the last known address of such person a written notice, to include:
(4) A description of the trustor’s right, if any, to refinance the balloon payment, including a summary of the actual terms of the refinancing or an estimate or approximation thereof, to the extent known.
If the due date of the balloon payment of a note subject to this subdivision is extended prior to the time notice is otherwise required under this subdivision, this notice requirement shall apply only to the due date as extended (or as subsequently extended).
(d) Every note subject to the provisions of this section shall include the following statement:
“This note is subject to Section 2966 of the Civil Code, which provides that the holder of this note shall give written notice to the trustor, or his successor in interest, of prescribed information at least 90 and not more than 150 days before any balloon payment is due.”
Failure to include this notice shall not invalidate the note.
