When renting an apartment, it is a good idea to keep any receipts for rent, deposit, or any other money you pay. The Austin Tenants’ Council provides this advice. Proof of Rent Payment(s) Keep a file of all your rent receipts as documentation that your rent is always paid and current. If the landlord will not provide you with receipt(s) for rent payments, write the receipt(s) yourself and obtain the landlord’s signature on those receipts for your records.
