Key Takeaways
- Your county runs the sale: New Castle, Kent, and Sussex each collect delinquent tax by monition under 9 Del. C. ch. 87, subch. II.
- The warning is posted on the house: the sheriff posts the monition and returns it to the court within 10 days (§ 8724).
- Twenty days later the writ can issue: a writ of venditioni exponas commands a public sale (§ 8725).
- Redemption runs 60 days from court approval: the purchase price plus 15 percent plus all costs (§ 8729).
- The sale can clear other liens: title vests in the purchaser freed and discharged from encumbrances (§ 8727).
- Selling first is the clean exit: back tax is normally paid from proceeds at closing, with no 15 percent add-on.
A Delaware property tax sale is a public sheriff's sale of the house itself, brought by the county to collect unpaid county and school tax. The usual route is the monition method under 9 Del. C. ch. 87, subch. II, named for the monition, a warning the sheriff posts on the property. If you are behind on property taxes in Delaware, that posted notice is where the timeline turns formal.
This guide walks the statute from the first filing to the sheriff's deed, shows what each county actually does, and explains what the 60-day redemption costs. It also covers the older Kent and Sussex procedure, and where a cash sale fits.
What Is a Delaware Property Tax Sale?
A Delaware property tax sale transfers the real estate itself, not a tax certificate, and it moves through the Superior Court. The county tax collecting authority files a praecipe with the prothonotary, a judgment is docketed against the property, and a monition is issued to the sheriff (9 Del. C. §§ 8722, 8723). Sussex County puts it bluntly: a monition purchase buys the property identified by the tax parcel number, not a tax lien (Sussex County Sheriff, September 2026).
County property tax is a lien on the real estate before any of this starts. Under 9 Del. C. § 8705, the lien runs for 10 years from July 1 of the levy year, and if the assessed owner still holds the property it runs until the tax is collected. In Kent and Sussex Counties the tax lien has priority over all other liens.
No proceeding can be brought unless the tax is a lien when the praecipe is filed (§ 8732). Remedies are cumulative under § 8703, and paying the full year's tax plus costs in all pending cases ends them.
Who Sends the Bill: Three Counties and Three Cities
County property tax in Delaware comes from one of three offices: New Castle County, Kent County, or Sussex County. Deadlines differ by county, which matters when you are counting the time left.
- New Castle County: FY27 tax bills covering July 2026 through June 2027 are due December 31, 2026, a date set by the General Assembly (New Castle County, September 2026).
- Kent County: bills are sent once school districts finalize rates, usually in early August, and the full annual payment is due by September 30 (Kent County Levy Court, September 2026).
- Sussex County: annual bills are due September 30, with supplemental bills due December 31, March 31, and June 30 (Sussex County Tax FAQ, September 2026).
Several Delaware cities also bill a separate city property tax. Wilmington, Dover, and Newark each run their own tax office, so paying the county does not clear the city. Newark issues annual real estate bills after July 1 and asks for payment by September 30 (City of Newark, September 2026). City charges are a separate payoff at closing.
What Happens When You Are Behind on Property Taxes in Delaware?
Penalty starts accruing the month after the due date, and the county can begin a monition case once the tax is delinquent. Each county sets its own penalty rate.
- New Castle County: a 6% penalty on property line items and 1% on school line items in the first delinquent month, then 1% per month on all line items (New Castle County, September 2026).
- Sussex County: 1.5% per month, and the county states that failing to receive a bill does not cancel the penalty (Sussex County Tax FAQ, September 2026).
- Kent County: the Levy Court assesses penalties but does not publish the rate on its tax pages. Confirm the figure with the Receiver of Taxes.
One protection is worth knowing in New Castle County. Under 9 Del. C. § 8701(d), a taxpayer who enters a payment plan authorized under § 8604(d) and complies with it cannot have the county issue a monition, apply for the writ, or sell the property at sheriff's sale. That covers county and school taxes on residential property for the 2025-2026 tax year.
A payment plan that is entered and kept is the cheapest way to stop the machinery. Call the county tax office before the case is filed and get the terms in writing. Propcash is not a lender or a law firm, and a plan you can keep beats any sale.
The Monition Timeline, Step by Step
The monition process runs from a court filing to a sheriff's deed, and most stages leave the owner something to do. Every step below comes from subchapter II or a county sheriff's terms.
| Stage | What happens | Authority | What the owner can still do |
|---|---|---|---|
| Tax goes delinquent | Penalty accrues monthly; the tax is already a lien | § 8705 | Pay, or ask the county about a written payment plan |
| Praecipe and judgment | The county files with the prothonotary; the amount is docketed as a judgment against the property | § 8722 | Pay the judgment plus costs, or list or sell the house |
| Monition posted | The sheriff posts it on a prominent part of the property and returns it to the court within 10 days | §§ 8723, 8724 | Pay within 20 days, or file a receipted tax bill as evidence of payment |
| 20 days after the return | If the judgment and costs go unpaid, the county may apply in writing for the writ | § 8725(a) | Last low-cost window: pay the judgment and costs |
| Writ of venditioni exponas | The prothonotary issues a writ commanding the sheriff to sell the property publicly | § 8725 | Sell or pay before sale day |
| Sheriff's sale | Sold publicly, with 100% of the purchase money due on sale day | County sheriff terms | Title has not moved yet, but the cheap exits are gone |
| Court approval | The Superior Court inquires into the regularity of the proceedings and approves the sale or sets it aside | § 8731 | Raise procedural defects with counsel before approval |
| 60-day redemption | The owner may redeem by paying the purchase price plus 15 percent plus all costs | § 8729 | Redeem, or sell and fund the redemption out of proceeds |
| Sheriff's deed | If no redemption, the purchaser petitions the court for an order directing the sheriff to deliver a deed | § 8728 | Ask the sheriff whether proceeds remain after costs |
One detail is easy to miss: the posting itself is the legal notice. Section 8724(b) states that posting constitutes notice to the owner and to all persons having any interest in the property. Under § 8726, the county finance department may also reject the final offer and expose the property to further sales.
How Does the 60-Day Redemption Period Work?
The owner may redeem at any time within 60 days from the day the sale is approved by the Court (9 Del. C. § 8729). Redeeming takes the purchase price, plus 15 percent in addition, plus all costs incurred in the cause. If the purchaser refuses payment or cannot be found in the county, the money is paid into court for the purchaser's use.
The clock starts at court approval, not at the sale. Kent County states it directly: the 60-day redemption is counted from the confirmation date (Kent County Levy Court, September 2026). Approval typically comes about a month after the sale, so the real distance from sale day to the end of redemption is closer to 90 days.
The 15 percent runs on the purchase price, not the tax debt. A house sold for $180,000 over a $9,000 tax judgment redeems for $180,000 plus $27,000 plus costs. An owner who redeems may then petition the court to note the redemption on the judgment record (§ 8730).
Once the 60 days pass without redemption, § 8728 lets the purchaser petition the court for an order directing the sheriff to execute a deed. Sussex County adds that a monition purchaser cannot take possession until 60 days after confirmation (Sussex County Sheriff FAQ, September 2026).
How the Three Counties Run Their Monition Sales
All three counties publish their monition sale terms, and the calendars differ enough to change how much time an owner has. Kent sells quarterly; New Castle and Sussex sell monthly.
| County | Sale schedule and place | Money due at the sale | Confirmation date |
|---|---|---|---|
| New Castle | Second Tuesday of each month, 9:00 a.m., City/County Building, 800 N. French Street, Wilmington | 100% due at time of sale; $10,000 certified funds at registration since March 11, 2025 | The Friday following the third Monday of the month after the sale |
| Kent | January, April, July, and October, last Tuesday at 10:00 a.m., Kent County Administrative Complex, 555 Bay Road, Dover | $2,000 certified funds per property at the sale, balance to the Sheriff by 2:00 p.m. the same day | The first Friday following the first Monday of the following month |
| Sussex | Third Tuesday of every month, 9:30 a.m., Sheriff's Office conference room, 22215 N. Dupont Blvd, Georgetown | 100% due by 3 p.m. on sale day; $4,000 registration deposit | The first Friday after the third Monday of the following month |
Sources for the table: New Castle County Sheriff Sales, Kent County Levy Court monition sale procedures, and Sussex County Sheriff sale terms and FAQ, all read September 2026. All three apply the same 60-day redemption under § 8729. Sussex adds one useful practice: sales can be stayed until 9:30 a.m. on sale day, so a payoff arranged the day before still counts.
The Older Kent and Sussex Tax Sale Procedure
Subchapter IV of the same chapter holds a separate, older sale procedure for Kent and Sussex Counties. Under 9 Del. C. §§ 8771-8779, the county mails the taxable an itemized bill and notice of sale, files a certificate with the prothonotary, and posts handbills in at least 10 public places. One goes on the land and one at the courthouse, with a newspaper notice before the sale, which is held at the courthouse door.
The differences that matter to an owner sit at the back end:
- No sale is approved if the owner is ready at court to pay the taxes, penalty, and costs (§ 8776).
- No deed issues for one year, and the owner or the owner's heirs may redeem within that year (§ 8776).
- Redemption costs 20 percent interest on the purchase money, plus costs and the deed expense (§ 8776).
- Surplus goes to the owner, paid at once after the tax, costs, and expenses of sale (§ 8779).
In practice, all three counties describe monition sales on their own websites, not subchapter IV sales. Kent County's finance department publishes a page titled Monition Sale Procedures, Sussex County's sheriff labels its tax sales as monition sales, and New Castle's lists them alongside mortgage and judgment sales. Treat subchapter IV as a live alternative in Kent and Sussex, and confirm which track a case is on.
What Happens to Money Left Over After the Sale?
The monition subchapter does not include a section directing how surplus proceeds are paid out. Section 8730 refers to proceeds the sheriff applies against liens, but nothing there creates the plain owner-payment rule at § 8779 in the older procedure.
County practice fills the gap. The New Castle County Sheriff states that homeowners and lien holders are expected to ask whether proceeds remain after the costs of sale. Anything unclaimed after 90 days goes to the Prothonotary for escrow and is listed on the Superior Court's Project Rightful Owner page (New Castle County Sheriff, September 2026).
Surplus is not a plan. Anything left over is whatever survives a price set at a courthouse rather than on the open market. Selling first keeps that decision with the owner.
Selling a Delaware House With Delinquent Property Taxes
You can sell a Delaware house with delinquent property taxes, and the unpaid county tax is normally paid off at closing out of the proceeds. The settlement agent orders the payoff, the amount comes off the top, and the lien is released. City tax and utility liens are handled the same way.
Before the sheriff's sale
This is the usable window. You still hold title, no writ has been executed, and paying the judgment and costs ends the case. A cash closing here funds the tax payoff from proceeds with no 15 percent add-on. Cash transactions need no bank financing or appraisal, and can close in as few as 7 days.
During the 60 days after court approval
A sale is still possible, but it has to fund a redemption at the purchase price plus 15 percent plus costs. That is a second window, not an equivalent one. Vacant houses are especially exposed, since nobody is there to see a posted monition, as our guide to selling a vacant house covers.
After the sheriff's deed
Once the redemption period passes and the court orders the deed, the sale is finished. What may remain is a claim on proceeds left after costs, and at that point a Delaware real estate attorney is the right call.
Where a cash sale fits
Propcash is a direct cash homebuyer, so we buy houses in Delaware ourselves rather than listing them. Sellers pay no fees or commissions, the house is bought as-is, and the seller picks the closing date. When the pressure is a court calendar rather than the building, that date is the point. You can request a cash offer on your Delaware house and weigh it against redeeming, refinancing, or listing.
Budget for the transfer tax either way. Under 30 Del. C. § 5402, the state rate is 3 percent of value. It drops to 2.5 percent where the county or city has enacted the full 1.5 percent local transfer tax, which puts the combined figure at 4 percent in most of the state. The statute apportions it equally between grantor and grantee.
Most Delaware owners have real equity to protect. Zillow's statewide home value index read $410,192 as of July 31, 2026, up 1.3% year over year (Zillow ZHVI, July 2026). A tax judgment of a few thousand dollars against that is solvable while the owner still holds title.
Tax trouble rarely travels alone. If a mortgage is also in default, Delaware's judicial scire facias process runs on its own clock, covered in our guide to stopping a foreclosure in Delaware.

Let's chatFrequently Asked Questions
How long do you have to redeem a house after a Delaware monition sale?
The owner may redeem at any time within 60 days from the day the sale is approved by the Superior Court, under 9 Del. C. § 8729. The clock runs from the approval date, not the sale date, as the Kent County Levy Court states on its monition sale page. Approval usually lands about a month after the sale, so the full gap often runs close to 90 days.
What does it cost to redeem a property after a Delaware tax sale?
Redemption under 9 Del. C. § 8729 takes the full purchase price paid at the sale, plus 15 percent, plus all costs incurred in the cause. The 15 percent runs on the purchase price rather than the tax balance, so a small tax debt can become a large redemption figure. Kent County states the same from the purchaser's side: a redeemed property returns the purchase money plus 15 percent.
Can you sell a Delaware house that has delinquent property taxes?
Yes. County property tax is a lien on the real estate under 9 Del. C. § 8705, and that lien is normally paid off at closing out of the proceeds, like a mortgage payoff. The settlement agent orders the payoff from the county, the amount comes off the top, and the lien is released. As long as no sheriff's deed has been ordered, the owner still holds title and can sell.
Which office runs a Delaware property tax sale?
The county tax collecting authority starts the case and the county sheriff conducts the sale. That is the Office of Finance in New Castle County, the Receiver of Taxes in Kent County, and the Department of Finance in Sussex County. The county's Superior Court holds the judgment docket and later approves or sets aside the sale.
Does a Delaware monition sale wipe out the mortgage?
Under 9 Del. C. § 8727, real estate sold under the monition subchapter vests in the purchaser freed and discharged from liens and encumbrances, including dower and curtesy rights. That is why mortgage servicers watch these cases and often pay delinquent county tax out of escrow. A separate provision, 9 Del. C. § 8704, preserves prior liens on certain Kent and Sussex sales, so lien treatment is a question for a Delaware attorney.
What happens to money left over after a Delaware tax sale?
The monition subchapter does not direct how surplus proceeds are paid out, though 9 Del. C. § 8730 refers to proceeds the sheriff applies against liens. The New Castle County Sheriff states that homeowners and lien holders are expected to ask whether proceeds remain after costs, and that anything unclaimed after 90 days goes to the Prothonotary for escrow. The older Kent and Sussex procedure at 9 Del. C. § 8779 requires the remainder to be paid at once to the owner.
