Direct answer
For Union County, New Jersey public land records, use the County Clerk’s official land-record index. Search by party and date when starting broadly, or use book/page or instrument number when you already have a document reference. Older land transactions may require the Clerk record room rather than the online index.
Choose the Clerk search route that matches the information you already have
The strongest search key changes as the research becomes more specific.
| What you know | Search route | Best next step |
|---|---|---|
| Party name and approximate period | Name + date-range search | Separate grantor and grantee roles and filter document types. |
| Recording date but uncertain party | Date-range search | Review the returned instruments and capture the correct parties. |
| Book and page | Book/Page search | Open the specific recorded reference and follow related documents. |
| Instrument number | Instrument-number search | Target the identified filing directly and verify its document type. |
Land records can represent different property events
Document type is part of the meaning, not just a filter.
Transfer
Deed
- Shows a recorded transfer instrument.
- Read parties and property description from the document rather than inferring them from the result list.
Financing
Mortgage and assignment
- A mortgage records a security interest; an assignment can move that interest.
- Follow later cancellations or releases when status matters.
Claim
Lien or notice
- A recorded claim can affect the property or a named party.
- Check for amendments, discharges, releases, or later court/record activity.
Process
Foreclosure or lis pendens
- These records may signal litigation or a property-related proceeding.
- Use the associated court source when procedural outcome is the question.
Handle online coverage and historical research separately
Union County publishes a clear boundary between the web index and older records.
Recent online index
Use the web system for recorded documents within its published online coverage.
Pre-index research
For older land transactions, use the Clerk record room rather than assuming a blank web search means no record.
Image availability
A search hit can exist even when a full document image is not yet available in the same online workflow.
Certified copy
When formal evidence is needed, use the Clerk certified-copy request tied to the identified instrument.
Build a land-record chain from document references
Move from one verified instrument to the next instead of treating a name-result list as a title history.

Separate court questionsIf the record points to litigation, use the court docket for procedural status rather than guessing from the land filing.How to avoid false land-record conclusions
A public land-record index is powerful because it preserves recorded instruments, but the researcher still has to resolve names and chronology.
Common names create the first risk. Use date ranges, grantor/grantee roles, document types, and the property description to make sure the filing belongs to the transaction you are researching. When a document references a prior book/page or another instrument, capture that reference and follow it rather than relying on a single isolated hit.
Coverage creates the second risk. Union County explains that its online index and its physical historical record room have different time spans. A no-result in the online system should therefore be read as a no-result within that online scope, not proof that an older county land transaction never existed. For formal use, order the certified document from the Clerk after the correct filing has been identified.
