What Is the Best Proof of Ownership of Property?

Someone asks you to prove the house is yours: a bank before a line of credit, an insurer after a storm, a permit desk before a solar install, a sibling in the middle of an estate. Most owners reach for whatever is nearest, usually a mortgage statement or a tax bill, then wonder why the reply asks for something else. The hierarchy is not arbitrary. One document sits at the top because of what recording does, and the rest corroborate it. If your real question is who owns a parcel that is not yours, the guide to how to find out who owns a property covers that search instead.

Why the recorded deed beats every other document

A deed is an instrument, not a certificate. To work it needs the names of the party giving up the interest and the party receiving it, words that actually convey, a description of the land, consideration and the signature of the grantor, and it has to be delivered to the grantee, which normally happens at closing¹. At that moment the transfer is complete between those two people.

Recording is the separate step that makes the transfer public, and it is the step that gives the deed its weight against everybody else. Filing the instrument with the county puts the public on constructive notice that you own the parcel¹. Florida's recording statute shows what happens without it: a conveyance, transfer or mortgage of real property is not good in law or equity against creditors or against later purchasers who paid value and had no notice, unless it has been recorded as the law requires². Every state runs a version of that rule.

Two consequences follow. The document people want is the recorded one, carrying the county's stamp and its book and page or instrument number. And you can always get another. Counties keep these files permanently and sell copies on request. Los Angeles County, to take one large example, lets any member of the public search and request its real estate records, and its holdings reach as far back as 1850³. Copies are ordered online, in person, by fax or by mail; that county deliberately does not put the records or the index on the web³. A deed lost in a fire is an errand, not a crisis.

What is the difference between a deed and a title?

Title is not a piece of paper. It is the ownership right that the recorded instruments, taken with the absence of competing claims, add up to, and the deed is one link in that chain. That is why a buyer's lawyer reads decades of filings rather than the latest deed alone, and why "where is my title?" has no answer for a house the way it does for a car.

The document that comes closest to a certificate of title is an insurance policy. An owner's title insurance policy protects you if somebody later sues claiming a right in the home that arose before you bought it, such as unpaid taxes left by a previous owner or a contractor who says nobody paid for the work⁴. It is optional in the sense that only the lender's policy is normally required, and the lender's policy covers the amount lent rather than your equity⁴. For proving ownership the policy matters twice: it names you as the insured owner, and it means an insurer already examined the chain and agreed to defend it.

Which documents count, ranked from strongest to weakest

The document that satisfies a permit desk is not always the one a bank wants. Working down this list in order saves a round of correspondence.

Manufactured homes are the common exception. Depending on whether the home was permanently attached to the land, ownership of the structure may live on a state issued certificate of title rather than in the deed records, so ask the state agency that titles manufactured housing which record governs yours.

How do I get a copy of my deed?

The office is the one that records real property documents in the county where the land lies. Its name changes with the state: recorder, county clerk, clerk of the circuit court, register of deeds, City Register. The route is the same everywhere.

1. Find the parcel number on your property tax bill or the assessment record. Street addresses are unreliable search keys; parcel numbers are not. The article on property records and parcel numbers explains how the three county offices fit together.
2. Search the index by your name as it appears on the deed, or by parcel number, online where the county publishes an index and at the counter or by mail where it does not, then note the recording date, the document type and the book and page or instrument number.
3. Identify the right instrument. You want the most recent deed that conveyed the property to you, not a later refinance, not a release, not a reconveyance.
4. Order a certified copy, not a plain copy. Certification is what makes a lender or a court accept it.
5. Check the vesting line on the copy for spelling, middle initials and the form of co-ownership. Errors here are fixed with a corrective instrument, and the longer they sit, the more expensive the fix.

Worked example, Los Angeles County, fall 2026. An owner needs a certified copy of a four page grant deed for a home equity application. The index search costs $0.50 per name per year with a $1 minimum⁵. The certified copy is $6 for the first page and $3 for each of the three remaining pages, so $15⁵. A card order adds $1.75 in handling⁵. The total lands at roughly $18, or about $36 with expedited mail at $18.50⁵. A plain copy is $5 for the first page⁵, a dollar less, and a lender will normally send it back. Other counties charge differently, and some publish deed images free while charging only for certification.

Is the owner of record always the real owner?

Mostly, and the exceptions are worth knowing because they are the cases where a search gives a confident wrong answer.

• The deed was signed but never recorded. It still binds the two parties, and it leaves the grantee unprotected against later buyers and creditors².
• The owner died. Title can pass by will or by operation of law long before any document reaches the county.
• A family transfer stalled. Divorce quitclaims and transfers into a family trust are frequently prepared, signed and then forgotten.
• The assessment roll lags. Assessors process transfers on their own schedule, so a roll can show the seller for months after a closing.
• Title is held for somebody else. A trustee or a company appears on the record while the economic owner does not.

California shows how the paperwork is supposed to close that gap. A change in ownership there includes gifts, inheritances and transfers that happen by operation of law, and it triggers reassessment at the current fair market value as of the date ownership changed⁶. A Preliminary Change of Ownership Report, form BOE-502-A, goes in at recording; when nothing is recorded, a Change in Ownership Statement, form BOE-502-AH, is due within 90 days of the transfer, or within 150 days of a death where there is no probate⁶. The penalty attaches only once the assessor asks in writing and the statement still does not arrive: $100 or 10 percent of the taxes on the new base year value, whichever is greater, capped at $5,000 for a home that qualifies for the homeowners' exemption and $20,000 for one that does not⁶.

What if the deed shows an LLC or a trust?

Then the record owner is the entity and your proof comes in two parts. The recorded deed establishes that the parcel belongs to the company or the trust. A second document establishes that you may act for it: a certification of trust naming you as trustee, or the state business filing together with the operating agreement for a limited liability company. The trust instrument itself stays private, which is why the certification exists.

Read the vesting line closely, because abbreviations carry meaning. A trustee designation, a successor trustee, a series designation on an LLC and a life estate all change who has to sign the next deed. The guide to property held by an LLC or a trust walks through the registry searches, and professionals who do this at volume will want the rules in the owner lookup guide for agents and investors.

California, Florida and New York City: the local answer

The hierarchy is national; the counter you walk up to is local.

California. The recorded deed at the county recorder is the proof, and the assessment record plus the change in ownership filings form the paper trail behind it⁶. Los Angeles County sells certified copies to anybody, with published fees and records back to 1850³⁵.

Florida. Recording is where the practical test lives, because an unrecorded conveyance loses to creditors and to later purchasers who paid value without notice². Deeds are filed with the clerk of the circuit court in the county where the property sits, and the certified copy from that office is what lenders ask for.

New York City. Deeds are recorded with the City Register and searched through the Automated City Register Information System, which covers Manhattan, Brooklyn, Queens and the Bronx with document images from 1966 to the present⁷. Staten Island records are held by the Richmond County Clerk⁸. Cooperative apartments are the city's special case: a co-op owner holds shares and a proprietary lease rather than a deed, so the proof is the stock certificate and the lease, not a recorded conveyance.

When someone records a document against your property

Deed fraud means a false deed, mortgage or lien is recorded against a property without the owner knowing or agreeing⁸. The targets are predictable: vacant homes, inherited houses between generations, absent owners, long paid off properties with no lender watching the file.

New York City publishes the defensive routine, and it transfers to any county. Check the register's records at least once a year, through the city's search system or the Richmond County Clerk for Staten Island⁸. Enroll in the Notice of Recorded Document Program, which has the City Register mail you a notice whenever a new document is recorded against your property, and name a trusted person to receive the alerts too⁸. Keep your mailing address current and report suspected fraud to the Sheriff's Office⁸. An owner's title insurance policy belongs on the same list, since defending a claim is what it pays for⁴.

What a valuation report adds, and what it cannot prove

A valuation report answers a different question from a deed, and mixing the two causes real disappointment. CheckValue produces an AI valuation report for an address with every figure sourced: a point value and range, comparable sales, the official price index, and for a United States address the name carried on the county roll with three facts beside it: the legal form behind that name, the date of the most recent transfer, and the town the assessor posts the bill to. That is useful when you are checking a parcel before an offer or reconciling what the county holds against what a listing claims. The free preview shows which sections an address returns before anything is paid for, and the help pages list the source behind each one.

It is not proof of ownership and it never claims to be. The report does not certify title, does not read the full chain of recorded instruments, does not find judgment or tax liens, and is not a licensed appraisal. For proof you go to the recorder; for a clean purchase you order a title search and a policy.

The ownership section is assembled from filings the counties publish, and it exists for research about a parcel. It may not be used for credit, employment, insurance or tenant-screening decisions, because those are the uses the Fair Credit Reporting Act reserves to consumer reporting agencies, a role CheckValue does not hold⁹.
