Re: Return of deposit and prepaid rent
Dear [OWNER OR AGENT NAME]:
I rented the unit identified above under our rental agreement. The agreement terminated on [__/__/____]. I paid a deposit of $[____] on [__/__/____] and prepaid rent of $[____ / ZERO]. I gave you my new mailing address, [ADDRESS], on [__/__/____] by [METHOD]; you received it on [__/__/____], as shown by [PROOF]. I am enclosing or identifying the relevant records: [LEASE, PAYMENT RECORD, ADDRESS NOTICE, CONDITION RECORD, PHOTOGRAPHS, YOUR ITEMIZATION / OTHER].
Under Wyo. Stat. § 1-21-1208(a), the balance of a deposit and prepaid rent, with a written itemization and reasons for any deductions, must be delivered or mailed by the later of 30 days after the rental agreement terminates or 15 days after the owner receives the renter's new mailing address. If the residential rental unit has damage, the statute extends that period by 30 days. The renter must notify the owner or agent within 30 days after termination where payment and notice may be delivered or mailed. My address-notice date and the condition record above support the calculation below.
| Deadline fact | Date or answer |
|---|---|
| Rental agreement termination | [__/__/____] |
| 30 days after termination | [__/__/____] |
| Owner's receipt of new mailing address | [__/__/____] |
| 15 days after address receipt | [__/__/____] |
| Later of those two dates | [__/__/____] |
| Damage to residential rental unit supported by the record? | [YES / NO; FACTS] |
| If yes, 30-day extension applied | [__/__/____ / NOT APPLICABLE] |
| Applicable return and itemization deadline | [__/__/____] |
As of [__/__/____], I have received [NO REFUND OR ITEMIZATION / $____ REFUND AND AN ITEMIZATION DATED ____]. I dispute these deductions, if any: [ITEM, AMOUNT, FACTUAL REASON / NONE]. Section 1-21-1208(a) permits application of a deposit to accrued rent, damage beyond reasonable wear and tear, cleaning to the unit's beginning condition, and other costs provided by contract. My move-in and move-out records show [SPECIFIC CONDITION FACTS].
☐ Nonrefundable amount issue, if applicable: The agreement stated [TERMS / NONE] about a nonrefundable deposit portion, and the written notice provided when the deposit was taken stated [TERMS / NONE]. Wyo. Stat. § 1-21-1207 requires both the rental agreement to state whether any portion is nonrefundable and written notice of that fact when the deposit is taken. The disputed amount is $[____]; the supporting facts are [FACTS].
My calculation is:
| Item | Amount |
|---|---|
| Deposit paid | $[____] |
| Prepaid rent remaining | $[____ / ZERO] |
| Less deductions I accept | ($[____ / ZERO]) |
| Less refund already received | ($[____ / ZERO]) |
| Amount demanded | $[____] |
Please deliver or mail $[____] to [PAYEE AND ADDRESS] and provide a written itemization with reasons for any deduction you continue to claim by [RESPONSE DATE]. If you disagree, please identify each disputed amount and the rental-agreement term, condition record, or other evidence on which you rely. This response date is my requested resolution date; it does not replace the statutory deadline calculated above.
If the matter remains unresolved, I may pursue the remedies available under Wyo. Stat. § 1-21-1208(c). That subsection permits recovery of the full deposit and court costs if an owner or agent unreasonably fails to comply with subsection (a) or (b). I reserve all rights and defenses. This letter makes no claim for attorney fees or other damages without a separate basis.
Sincerely,
[RENTER OR AUTHORIZED COUNSEL SIGNATURE]

A demand letter is a formal written request to fix a problem or pay what is owed, sent before anyone files a lawsuit. It gives the other side a real chance to settle, creates a record of your attempt to resolve things, and in many cases (unpaid debts, insurance claims, broken contracts) starts a legally required response window. A well-written demand letter lays out what happened, what you want, and a deadline to act, which is often enough to get results without ever going to court.
