Delaware Quick Rule: No statutory grace; 5-day notice required before filing.

Before a Delaware landlord can file for eviction over unpaid rent, state law requires a written demand that gives the tenant time to pay. Under 25 Del. C. § 5502, that demand must allow not less than 5 days to pay before the rental agreement terminates and you can go to Justice of the Peace Court. There is no federal pay-or-quit notice period, so Delaware's rule controls; the only federal overlay is the CARES Act 30-day notice, which applies solely to federally backed or federally subsidized properties and runs on top of the state notice. Getting the day count, content, and service method right is what keeps a summary possession case from being dismissed on a technicality.

How many days the notice must give

Delaware's demand for unpaid rent must state a deadline of not less than 5 days after the date the notice was given or sent (25 Del. C. § 5502). Five days is the floor, not a target: you may give more, but never fewer. The clock runs from the day you deliver or mail the notice, so build in mail transit time if you send it rather than hand it over.

Note the difference between the 5-day late-fee grace period and the 5-day cure period in the notice. Under § 5501(d), you cannot impose a late fee until rent is at least 5 days past the agreed payment date. The § 5502 notice is a separate step you can serve any time after rent is due, including during that grace window, but the tenant still gets a fresh 5-day period to pay once the notice is served.

What the notice must say

A defective demand is the most common reason a Delaware nonpayment case falls apart. The written notice under § 5502 should clearly:

Keep the demand to rent that is actually owed. If your ledger includes a late fee, confirm it complies with § 5501(d) first, which caps the late charge at 5% of the monthly rent. Overstating the balance gives the tenant a defense.

How to serve the notice

Delaware recognizes several delivery methods for the § 5502 demand, and documenting service is as important as the notice itself:

Because the 5-day period runs from when the notice is given or sent, keep the certified-mail receipt or a signed proof of hand delivery. If you rely on mail, count the transit days into your timeline before you file.

The tenant's right to cure

Delaware gives tenants a strong right to reinstate the tenancy by paying. Under § 5502, if the tenant pays all rent due before you initiate the summary possession action, you may not then file for possession or for failure to pay rent based on that demand. If the tenant pays after you have filed and you accept the payment without a written reservation of rights, you cannot maintain the action for the past-due rent.

The practical takeaway: if you intend to keep pursuing possession while still accepting money, put your reservation of rights in writing at the time you accept it. Otherwise, accepting payment can waive the case.

Late fees, grace period, and the no-office rule

Two § 5501(d) rules shape when rent is truly "late" in Delaware. First, a late charge cannot exceed 5% of the monthly rent and cannot be imposed within 5 days of the agreed payment date. Second, if you do not maintain an office in the county where the unit is located where the tenant can pay rent, the agreed time for payment is extended by 3 days beyond the due date, effectively pushing back both the grace period and when rent counts as late.

These rules affect your ledger and your notice math, but they do not change the § 5502 requirement of at least 5 days to cure. Serve the demand cleanly, wait out the period, then file your summary possession action in Justice of the Peace Court if the tenant has not paid.

The Pay-or-Quit Notice Process in Delaware

Once rent is late and no grace period applies, the landlord must serve a formal 5-day pay-or-quit notice (25 Del. C. § 5501) before filing for eviction. This notice must state the total amount owed and give the tenant the option to either pay in full or vacate. If the tenant does neither, the landlord may file an unlawful detainer action in Delaware court.

Frequently Asked Questions

How many days is a Delaware late rent notice?

The demand must give the tenant not less than 5 days after the notice is given or sent to pay before the rental agreement terminates, under 25 Del. C. § 5502. You may give more than 5 days, but never fewer.

Is Delaware's notice period set by federal law?

No. There is no federal pay-or-quit notice period; Delaware's 5-day rule under § 5502 controls. The only federal overlay is the CARES Act 30-day notice, which applies only to federally backed or federally subsidized properties and runs in addition to the state notice.

How must the notice be delivered in Delaware?

You can deliver it in person to the tenant or an occupant at least 18 years old, mail it by certified, registered, or first-class mail (the return receipt is prima facie evidence of delivery), or use a special process server appointed by the court. The 5-day period runs from when the notice is given or sent.

Can the tenant stop the eviction by paying?

Yes. If the tenant pays all rent due before you file, you cannot then bring the summary possession action. If the tenant pays after you file and you accept it without a written reservation of rights, you cannot maintain the action for the past-due rent.

How much can a Delaware landlord charge in late fees?

Under § 5501(d), a late charge cannot exceed 5% of the monthly rent and cannot be imposed within 5 days of the agreed payment date. If you keep no office in the county where the unit is located, the payment time is extended by 3 additional days.

Where do I file if the tenant doesn't pay?

After the 5-day notice period expires without payment, you file a summary possession action in the Delaware Justice of the Peace Court for the county where the property is located.
