Late Payment Fee
I recall that in California, if payment is due by a certain date, it's not whether or not the payment is received by that date, but rather what date the payment was made. In other words, if a payment is due on the 31st and the postmark of the envelope is before that date, then the payee can't charge a late fee just because the check arrived late.
Is this correct? And can someone give me the California Code which addresses this.
