How to Find Block, Lot, Qualifier or Tax Account Details

If you are searching a condo, townhouse, commercial unit or subdivided property, the qualifier may matter. Always copy the block, lot and qualifier exactly as shown in the official record.

Local Tips Most Guides Miss

1. Use the municipality filter first: Middlesex County has many towns, and common street names can appear in more than one municipality.
2. Save block, lot and qualifier: These are the most useful identifiers for matching assessment, tax, deed and GIS records.
3. Tax payment is municipal: County assessment records do not mean the county collects your property tax payment.
4. Use Clerk records for legal history: Deeds, mortgages, liens and releases are land records, not just assessment data.
5. Check the online document date ranges: The Clerk states deeds from 1929, mortgages from 1950 and other documents from 1958 are available online.
6. Use Property Fraud Alert: Homeowners should consider fraud alerts for recorded document activity.
7. Do not expect Clerk staff to do title searches: The Clerk can explain the indexing system, but cannot perform a title search.
8. Use GIS for map context only: Parcel maps are helpful, but legal boundary decisions need deeds, maps, title work and surveys.
9. Compare record dates: Recent deed recordings, tax payments and assessment updates may not appear everywhere at the same time.
10. Verify before closing: Taxes, deeds, liens, releases, mortgages and title concerns should be checked through official sources and title professionals.
