Oklahoma rules for demand letters

Small claims court in Oklahoma

The general small claims limit in Oklahoma is $10,000. The Oklahoma small claims form asks whether you asked for payment before filing. The statutory claim affidavit states that you demanded payment and the defendant refused, so ask for payment before you file.

The small claims court finder shows the filing fee for your amount, where to file and how to serve; our Oklahoma small claims guide walks through the whole case.

Security deposits in Oklahoma

The landlord must return the balance of the deposit within 45 days after the tenancy ends, possession is delivered, and the tenant makes a written demand for it. If the tenant makes no written demand within six months after the tenancy ends, the deposit reverts to the landlord. A landlord who does not comply can be ordered to pay back the deposit and any prepaid rent; the statute sets no multiplier. 41 O.S. § 115(B)

Make a written demand for the deposit (this letter can serve). The landlord's 45 days do not start until you do, and if you make no written demand within six months after the tenancy ends, the deposit reverts to the landlord.

Consumer protection notice in Oklahoma

The sources we checked show no general written-notice requirement before a consumer lawsuit under the Oklahoma Consumer Protection Act. No pre-suit demand letter is required. A violator is liable to the consumer for actual damages and costs of litigation, including reasonable attorney fees.

What a demand letter should say

A demand letter is a short, factual request for payment. It names who owes whom, how much, and why; it sets a date to pay; and it says what you will do next if you are not paid. Keep it to what you could prove to a judge: the agreement, the dates, the amount, and any payments already made.

  • Your name and mailing address, the date, and the other side's name and address.
  • The amount you are asking for and how you got to it.
  • A short account of what was agreed and what went wrong.
  • A clear deadline and how to pay.
  • Your next step if you are not paid, such as filing in small claims court.

Send it in a way you can prove, such as certified mail with a return receipt, and keep a copy for the court file.
