Finding out who owns that Victorian in Somerville or checking the tax history on a plot in Bernardsville isn't as simple as a quick Google search. Trust me. People think they can just type an address into a search engine and get the full story. They can't. You’ll mostly find outdated Zillow estimates or lead-generation sites trying to sell you a background check.
Actually, the real data lives in a few specific, slightly clunky government databases.
If you are looking for a Somerset County property search, you're basically dealing with two different worlds: the Tax Assessor’s data and the County Clerk’s land records. One tells you what the government thinks the house is worth for tax purposes. The other tells you who actually legally owns it and if there are any nasty liens attached to the title.
The Tax Man’s Digital Paper Trail
Most folks start with the tax records. It makes sense. You want to see the "MOD-IV" data—that’s just Jersey-speak for the official tax list. In 2026, the NJ Division of Taxation and the Somerset County Board of Taxation keep these records fairly accessible.

You can head over to the Somerset County Tax Parcel Viewer. It’s an interactive GIS map. It’s kinda cool, honestly. You can zoom into specific lots in Franklin Township or Bridgewater and see the property boundaries laid out over satellite imagery.
But here is the catch.
New Jersey has some strict privacy laws, specifically N.J.S.A. 56:8-166.1. This means that on many public-facing GIS maps, the owner’s name is redacted. You’ll see the block and lot, the acreage, and the assessed value, but the "Owner" field might just say "REDACTED" or "Privacy Protected."
To get around that, you usually have to go to the state’s searchable tax system (the YourMoney.NJ.Gov portal or the specific Somerset County Board of Taxation site). These databases are updated annually in January. If a house sold in June, the tax portal might still show the old owner until the next year’s "Final List" is published.
Digging into the County Clerk’s Records
If you need the "now" information—the deed that was signed last week—the tax portal won't help you. You need the Somerset County Clerk.
The Clerk’s office at 20 Grove Street in Somerville is the keeper of the "Land Records." This is where every deed, mortgage, lis pendens (foreclosure notice), and tax lien is recorded.
The good news? They have an online search portal.
The bad news? You have to register for a free account just to look at the images.
Once you're in, you can search by name or "Legal Description" (Block and Lot). Searching by name is the most common way, but it's tricky. If you're looking for "John Smith," you're going to have a bad time. There are too many. It’s always better to search by the property's specific Block and Lot numbers, which you can find on your most recent tax bill or via the GIS map mentioned earlier.
The Clerk’s online system uses a "Book and Page" or "Instrument Number" filing system. You can view unofficial copies for free. They’ll have a watermark. If you need a certified copy for a legal proceeding or a closing, expect to pay about $10 plus $1 per page.
Why the Data Might be "Wrong"
I see people get frustrated because the "Value" on a property search doesn't match the "Value" on a real estate site.
The assessed value is what the town uses to calculate your taxes. In Somerset County, towns like Hillsborough or Montgomery don't reassess every single year. The assessed value might be based on a "market value" from five years ago.
Then there is the Equalized Value. Because different towns assess at different percentages of true market value, the state applies a "ratio." If a town assesses at 80% of market value, a house assessed at $400,000 is "actually" worth $500,000 in the eyes of the tax board.
Don't mistake the tax assessment for an appraisal. They aren't the same.
Common Pitfalls in a Somerset County Property Search
- The "Hidden" Owner: Many high-end properties in Far Hills or Peapack-Gladstone are owned by LLCs. You’ll do a search, and the owner will be "123 Main Street LLC." To find the person behind that, you’d have to jump over to the NJ Treasury’s Business Entity search.
- The Municipality Confusion: People often search "Princeton" and get no results. Parts of Somerset County have Princeton mailing addresses but are actually in Franklin Township or Montgomery Township. You have to search by the legal municipality, not the post office name.
- The Dead Ends: Sometimes a deed isn't recorded immediately. There can be a "gap" of several weeks between a closing and the Clerk's office digitizing the document.
Using OPRA for the Deep Stuff
If the online portals aren't giving you what you need—maybe you want to see the building permits, underground storage tank records, or code violations—you have to use OPRA.

The Open Public Records Act.
Every municipality in Somerset County (like Bedminster, Manville, or North Plainfield) has a Clerk who handles these. You submit a written request. By law, they have seven business days to get back to you. This is how you find out if that "newly renovated" kitchen actually had a permit pulled or if there’s an old oil tank buried in the backyard that didn't show up in the Clerk's deed search.
Actionable Next Steps
If you're starting a search today, don't just wing it.
First, go to the Somerset County GIS Parcel Viewer. Get the exact Block and Lot number for the property. This is your "source of truth" for all other databases.
Second, take that Block and Lot and plug it into the NJ County Tax Board Search. Select "Somerset" and look for the "Assessed Value" and "Year Built" to verify the physical characteristics of the house match what you're being told.
Third, if you're a buyer, check the County Clerk’s Land Records to see if there are any open mortgages or liens. If the seller says the house is "clear" but you see a 2015 mortgage with no "Discharge" or "Satisfaction" recorded next to it, that’s a red flag you need to bring to your title company.
Finally, if you own property in the county, sign up for the Property Recording Notification Service. It’s a free service from Clerk Steve Peter’s office. They’ll email you whenever a document is recorded against your name or property. It’s the easiest way to keep an eye out for potential deed fraud without paying for one of those expensive "Title Lock" services you see on TV.
Stick to the official portals. The "free" third-party sites are usually just a waste of time.
