One letter is usually not the whole plan

The 4-step sequence

1. Step 1: Document move-out, condition, key return, delivery of possession, and your written mailing address.
2. Step 2: Make a firm request for the deposit or proper itemized accounting after the Indiana timing issue appears.
3. Step 3: Escalate with Indiana Code chapter 32-31-3 and the missing or incomplete response.
4. Step 4: Make a final demand before Indiana Small Claims Court or other appropriate action.

Why Step 1 matters in Indiana

Indiana's statutory process is tied to the tenant supplying a mailing address in writing. Step 1 helps document that address at the same time it documents move-out, possession return, and condition.

That makes later letters cleaner. Instead of arguing only about whether 45 days passed, you can point to the address, the move-out facts, and your proof of delivery.

When to move from one step to the next

• Use Step 1 before or at move-out when you still want cooperation.
• Use Step 2 after the deadline problem appears or the landlord sends an incomplete response.
• Use Step 3 when you need to cite the Indiana statute and press the entitlement issue harder.
• Use Step 4 only when you are ready to make a final written demand before deciding whether to file.
