Delaware Code Title 25. Property § 7010. Rent--Prohibited lump sum payments:  acceptance of rent

(a) Rental payments must be paid by the tenant to the community owner or landlord in equal dollar amounts, or as close thereto as possible, and must be extended equally, pro rata, over a calendar year.  Any provision in a rental agreement, or otherwise, that requires rental payments or rental increases to be paid in 1 lump sum is void.  However, a tenant may request and the community owner or landlord may agree that rental payment be made in a 1-time lump sum, semi-annual, or quarterly payment made by the tenant;  nor does this subsection prevent a community owner or landlord from offering discounts as incentives to homeowners to pay annually, semi-annually, or quarterly, provided it is made clear that the homeowners are under no obligation to pay in any way except monthly.

(b) If a community owner or landlord accepts a cash payment for rent, the community owner or landlord shall, within 3 days, give the tenant a receipt for that payment.  The community owner or landlord must maintain a record of all cash receipts for rent for 3 years.
