A person writing an NSF check is liable for treble damages under California Civil Code Section 1719 unless that person pays the face amount of the check, the service charge, and the cost of mailing a written demand by certified mail within 30 days of mailing of the notice. The treble damages shall not be less than $100.00 nor more than $1,500.00.
When the person becomes liable for the treble damages, that person is no longer liable for the service charge or the cost of mailing the treble damages letter.
