Late Fees in Oklahoma

[Account Closed]

Is it legal to charge a basic late fee and a daily late fee after so many days in Oklahoma?

For example, our grace period is until the 5th, then we charge a $50 fee. If someone still isn’t paid at the 10th could we start charging a per day late fee?

How would you go about doing that if it’s not at lease renewal? Or could you not change it until lease renewal time?
