Ask most Claremont owners to identify their property and they will give you a street address. Ask escrow and you get something that looks like this: Lot 14 of Tract No. 12345, in the City of Claremont, County of Los Angeles, State of California, as per map recorded in Book 271, Pages 18 to 20 inclusive of Maps, in the office of the County Recorder of said county.
That is the LEGAL DESCRIPTION, and it is the only identification that governs. A street address is a mailing convenience assigned by a city and changeable at will. The legal description is what the deed conveys, what the policy insures, and what a court reads if there is ever an argument.
Lot and block: the Claremont default
Most residential Claremont parcels are described by reference to a recorded SUBDIVISION MAP, often called a tract map. A developer surveyed a piece of land, divided it into numbered lots with streets and easements, and recorded that map with the county. Every lot on it can then be described in one short sentence pointing at the map.
The elegance of the system is that the map does the geometry. The bearings, the distances, the curve data, the easements dedicated to the city, the notes, the reference monuments: all of it lives on the recorded map, and every deed citing the map incorporates it by reference.
This matters practically. If you want to know where your line actually runs, or where a utility easement crosses your yard, the recorded map is the primary document, not an online parcel viewer. A title company can generally tell you the recording book and page. Pulling the map itself is worth doing before you build a fence or a wall. Where the line and the fence disagree, the encroachment guide covers what follows.
Metes and bounds: the older description
Some Claremont-area parcels, particularly land carved out of larger agricultural holdings before modern subdivision, are described by METES AND BOUNDS. That is a written walk around the perimeter: a beginning point, then a series of directions and distances, then a close back at the start.
Metes and bounds descriptions are precise in theory and troublesome in practice. They can begin at a point defined relative to something that no longer exists. They can reference a road centerline since realigned. They can carry a transcription error forward through decades of deeds because everybody copied the prior deed rather than re-surveying. And they can fail to CLOSE, meaning the described walk does not actually return to its starting point.
A description that does not close, or that overlaps a neighboring description, is a real title matter. It is also exactly the situation where a survey stops being optional. When one is warranted is covered in the lot-line survey guide.
The APN is not a legal description
The assessor's parcel number is a tax administration tool. Los Angeles County assigns it so the assessor can track a parcel for assessment and billing. It is useful, it appears on almost every document you will handle, and it is NOT a legal description.
Assessors combine and split parcels for their own convenience. Two legally separate lots can carry one APN because they are assessed together. One legal parcel can be given a new APN after a boundary adjustment. A deed conveying an APN and nothing else is a description problem waiting to be discovered, and title companies do not treat it as sufficient.
If you own what you believe are two lots sharing an APN, do not assume they are separately saleable. That is a question about the recorded map, the Subdivision Map Act, and the city, and it is answered by a title officer and a land use professional, not by the tax bill.
Condominiums describe airspace
A Claremont condominium legal description looks different because a condominium is not a piece of ground. It is typically a defined airspace unit shown on a recorded CONDOMINIUM PLAN, plus an undivided fractional interest in the common area, plus rights granted by the declaration.
Three documents are therefore doing the work: the condominium plan, the tract or parcel map underneath it, and the recorded declaration. A buyer reading only the deed sees one line. The obligations that come with a common interest sit in the CC and Rs guide, and assessment obligations attach the way described in the HOA lien guide.
Where descriptions go wrong
The common failures are mundane. A digit transposed in a lot number. A tract number correct but the book and page wrong. An except-therefrom clause dropped when a deed was retyped, so a strip previously excluded appears to be conveyed. A description that includes a portion deeded to the city for street widening decades earlier.
Most are caught in examination and cured with a corrective instrument. The mechanics of that repair are in the corrective deed guide. Some are not caught for years, surfacing when a neighbor develops or a lender orders a survey, and by then the resolution may require agreement from parties with no reason to cooperate.
What to actually do
Read the legal description on your grant deed and on the preliminary report and confirm they match each other. That single comparison catches a meaningful share of description errors, and it takes two minutes. Reading the report properly is covered in the preliminary report guide.
If you are buying vacant land, a parcel with an unusual shape, anything described by metes and bounds, or anything where the fences plainly disagree with the map, treat a survey as part of the purchase rather than an upgrade. And if any of it looks off, that is a title officer question and, where a boundary or an ownership right is genuinely in dispute, a question for a real estate attorney. Nobody should reassure you that a description is adequate without examining the record.

Frequently asked questions
Is my assessor's parcel number the same as my legal description?
No. The APN is a tax administration identifier assigned by the county assessor, who combines and splits parcels for assessment convenience. The legal description is what a deed conveys and a policy insures. A conveyance identifying property only by APN is generally treated as inadequate.
Where do I find the recorded map for my Claremont lot?
Your legal description cites it directly, usually as a book and page of Maps in the office of the Los Angeles County Recorder. Your title company can typically supply a copy. The recorded map, not an online parcel viewer, is the document that shows dedicated easements, dimensions, and monuments.
What does it mean when a legal description does not close?
It means the written sequence of bearings and distances does not return to its starting point, so the described boundary is mathematically incomplete. That is a genuine title matter, common in older metes and bounds descriptions, and it typically requires a survey and legal review rather than a simple correction.
My deed and my title report describe the property differently. Is that a problem?
It may be, and it is worth raising immediately. Differences range from harmless formatting to a dropped exception clause that changes what is conveyed. Send both documents to your title officer and ask them to reconcile the descriptions before closing rather than after.
