In Florida, what does the law say about nonpayment of rent, notice before filing?
Answered for: Florida
If the tenant fails to pay rent when due and the default continues for 3 days, excluding Saturday, Sunday, and legal holidays, after delivery of written demand by the landlord for payment of the rent or possession of the premises, the landlord may terminate the rental agreement.
This is Florida's statute on nonpayment of rent, notice before filing, in its own words.
This answer is true in Florida and nowhere else on this site. Another jurisdiction is another answer, or an honest gap: see what has been read for Florida.
