New Castle County, Delaware tax sales
How tax sales work in New Castle County, Delaware
Delaware law controls every tax sale in New Castle County — the county runs the sale, but what is sold, what it pays and how long the owner can redeem are all set by the state:
| What Delaware sells | Redeemable tax deeds |
|---|---|
| Interest / penalty | Depends on the method: monition sales — 15% penalty on the purchase price (9 Del. C. § 8729); direct sales in Kent and Sussex Counties — 20% interest on the purchase money (9 Del. C. § 8776) |
| Redemption period | Depends on the method: monition sales — 60 days from Superior Court approval/confirmation of the sale (§ 8729); direct sales in Kent and Sussex Counties — 1 year from the time of sale, and no deed may be made until that year expires (§ 8776) |
| When sales happen | Year-round as scheduled by county — New Castle County monition (sheriff) sales are held monthly, on the second Tuesday of the month; Kent and Sussex sales are scheduled by the county tax collecting authority and returned to Superior Court for approval |
| Governing law | 9 Del. C. Chapter 87 (§§ 8701 et seq., Collection of Delinquent Taxes), esp. §§ 8729, 8776 |
| County (Census) | New Castle County — county, Delaware · FIPS 10003 |
Delaware has no single statewide rule: the monition method (all three counties, court-driven, 100% due at sale in New Castle County) gives only 60 days at a 15% penalty, while the Kent/Sussex direct-sale subchapter gives a full year at 20% — always identify which subchapter a sale is brought under before pricing redemption risk. Wilmington's own city monition process also uses a 60-day redemption.
The process, step by step
1 · The list publishes. Delaware sales run on this rhythm: Year-round as scheduled by county — New Castle County monition (sheriff) sales are held monthly, on the second Tuesday of the month. The county's sale list — the parcels actually being sold — is published ahead of the sale by the county office that runs it, and in many Delaware counties also through the state's sale channels (mostly in-person — county sheriff sales supervised by Superior Court (e.g. New Castle County, City/County Building, Wilmington); municipality/county-specific; no statewide online platform verified).
2 · Register and fund — before sale day. Registration and bidder deposits are handled by the county or its sale platform and close before the sale, in most counties the day before. The amount and ID requirements are set in the county's own sale notice, not in state law — confirm them on the current published notice before you rely on them.
3 · Research every parcel. Compare the taxes owed against assessed value and recorded sales, check property type and occupancy signals, and price in the state's redemption rule above: it decides whether your money comes back with the statutory return, or your path runs to the property itself.
4 · Bid the number you wrote down. Set your max bid (deeds) or floor rate (liens) from the research, before the sale opens. The state's return is paid on the tax obligation — not on whatever extra a bidding war adds on top of it.
5 · After the sale. Owners redeem inside the window above; lists change as they do. Track the parcels you care about, because a watched property redeeming or withdrawing is information you want before — not after — you wire a deposit for the next sale.
What New Castle County publishes — and our verification status
Under Delaware law, the county publishes its sale list as a public record ahead of each sale. What we have not done is guess at this county's exact channel: which office posts the list, in what format, and on what posting schedule are being verified county by county against the county's own publications. Until that check is complete, this page carries the verified state rules — not a live New Castle County sale list — and says so plainly.
