Florida Statutes Title XXXIX. Commercial Relations § 687.08. Person lending money to give borrower receipt for payments;  contents of receipt;  penalty for violation

(1) Every person, or the agent, officer, or other representative of any person, lending money in this state upon security shall, whenever the borrower of such money makes a payment of any money, either principal or interest, immediately upon such payment being made, give to the borrower a receipt, dated of the date of such payment, which receipt shall state the amount paid and for what such payment is made.  If such payment is for interest on the sum borrowed, the receipt shall so state.  If the sum so paid is to be applied to the payment of the principal sum borrowed, the receipt shall so state.  Every such receipt shall be duly and properly signed by the person, or the agent, officer, or other representative of the person, to whom such money is paid.  In lieu of providing such receipt, a lender may furnish to the borrower an annual statement showing the amount of interest paid on the loan during the previous year as well as the remaining balance on the loan;  except that a simple receipt shall be given to the borrower for each payment which is made in cash or for any payment for which receipt is requested in writing by the borrower.

(2) Whoever refuses, upon demand, to give a receipt or statement complying with the requirements of this section shall forfeit the entire interest upon such principal sum to the borrower.
