Statute of limitations by state
Be careful not to restart the statute of limitations. Anytime you take an action with an account, the statute of limitations is restarted. Making a payment, making a promise of payment, entering a payment agreement, or making a charge using the account can restart the statute of limitations on an account. When the clock restarts, it restarts at zero, no matter how much time had elapsed before the activity.
The statute of limitations on debt in Florida puts a time limit on the amount of time you can be sued for a debt.
