Property records in Delaware are maintained at the county level. The County Assessment Office handles property valuations and assessment data. The County Treasurer handles tax bills and payments. These are separate offices with separate databases.
What this page covers: Delaware property assessment lookups, tax record searches, and parcel/ownership data. What it does not cover: Recorded documents like deeds and mortgages (those are on the Recorded Documents page) or property transfer history.
Where to start: For property values and tax assessments, start with the County Assessment Office. For tax payment history and bills, go to the County Treasurer. For ownership verification, you may need both the assessment records and the recorded documents.
Common mistake: Property assessment records (values and taxes) and recorded documents (deeds and liens) are maintained by different offices in Delaware. The County Assessment Office handles assessments; the Recorder of Deeds handles recordings. Search both if you need the full picture.

Frequently Asked Questions
Where do I search Delaware property records?▼
In Delaware, property records — including parcel data, assessed value, deeds, and tax history — are primarily maintained at the county level by each county's Assessor and Recorder. Statewide oversight and reporting are provided by the Official Delaware Property Records at revenue.delaware.gov. See the cards below or the county page for direct local search links.
Is there a free statewide Delaware property search?▼
Delaware does not have a single statewide free property search; deed and assessment data are searched at the county level. The Official Delaware Property Records publishes statewide property-tax rules and aggregate data at revenue.delaware.gov; for individual parcels, use the county assessor or recorder.
What's the difference between the Assessor and the Recorder in Delaware?▼
The county Assessor determines property values for tax purposes and maintains the parcel roll. The county Recorder (sometimes Clerk-Recorder) records deeds, mortgages, liens, and other instruments affecting title. In some Delaware countys these are combined offices; in others they're separate. The Official Delaware Property Records at revenue.delaware.gov publishes the full list.
How do I find a Delaware parcel ID (APN/PIN)?▼
Parcel identification numbers (APN, PIN, or parcel number depending on the county) are assigned by the county assessor. They appear on every tax bill and on the county's online property-search interface. Once you have the parcel ID you can look up assessed value, ownership history, and recorded documents through the county site; the statewide overview is at revenue.delaware.gov.
How do I challenge a Delaware property assessment?▼
Assessment appeals in Delaware are filed at the county level with the local assessment appeals board, typically within a deadline set after annual valuation notices are mailed. The Official Delaware Property Records publishes the statewide rules, deadlines, and appeal forms at revenue.delaware.gov.
