County Recorder's Office: What It Records, What It Does Not, and How to Search It
A county recorder's office files and indexes deeds, mortgages and liens. See what it does not do, how it differs from the assessor and treasurer, and real figures.
Quick answer
A county recorder's office accepts real estate documents such as deeds, mortgages and liens, stamps each with a unique record identification, and indexes it so the public can find it later. It does not check that a document is valid, value property, or collect property tax. Those jobs belong to other offices.
What is a county recorder's office?
Arizona's statute is a plain description of the job. It says the recorder "shall have custody of and shall keep all records, maps and papers deposited in the recorder's office" (Arizona Revised Statutes 11-461). The office is a keeper of documents. It is not a judge of them.
The same statute says instruments are recorded "consecutively as of the time they are received" and that the recorder marks each one with a record identification that fixes its place in the sequence, plus a record location so it can be pulled up again. In other words, the order of recording is part of the record.
The name varies. Arizona uses county recorder. In Texas the county clerk keeps real property records. In Illinois, the Cook County Clerk has a Recordings Division. In Philadelphia the Department of Records does it. Other places say register of deeds or city register. This guide uses "recorder's office" for all of them and notes the local name where it matters.
Definition
County recorder's office — The local government office that receives real estate documents, adds them to the public record in the order received, and indexes them so anyone can look them up.
What does the county recorder record?
A recorder takes in documents that affect who owns land or who has a claim against it. Cook County describes its division as one that "accurately records, stores and maintains land records and other official documents" (Cook County Clerk, Recordings).
The usual contents of the land records are:
Documents you will find in the recorder's records
Each of these is a recorded document type you will see when searching a county index:
- Deeds, which transfer ownership (warranty deeds, quitclaim deeds, trustee deeds and others).
- Mortgages and deeds of trust, which pledge the property as security for a loan.
- Satisfactions or releases, which show a loan was paid off.
- Assignments, which move a loan from one holder to another.
- Liens and judgments, which are claims against the property or its owner.
- Easements, plats and subdivision maps, and condominium declarations.
How many documents does a recorder handle?
Two official open data sets show the scale in large offices. New York City counts documents recorded through ACRIS, the Automated City Register Information System, across the five boroughs for 2025-10-01 to 2026-09-30 (NYC Department of Finance, ACRIS Real Property Master). Philadelphia publishes real estate transfers from its Department of Records for 2025-10-03 to 2026-08-11 (City of Philadelphia, Real Estate Transfers).
These are counts of recorded documents. A mortgage count is not a count of unpaid loans, and one deed can cover several parcels. Philadelphia's period is shorter than a year, so the two columns are not directly comparable.
| Document type | New York City (2025-10-01 to 2026-09-30) | Philadelphia (2025-10-03 to 2026-08-11) |
|---|---|---|
| Deeds | 52,806 | 29,132 |
| Mortgages | 42,132 | 44,182 |
| Satisfactions | 37,444 | 28,925 |
| Assignments | 24,302 | 11,615 |
Why does recording a document matter?
Recording gives public notice. Arizona law says "no instrument affecting real property gives notice of its contents to subsequent purchasers or encumbrance holders for valuable consideration without notice, unless recorded as provided by law in the office of the county recorder" (Arizona Revised Statutes 33-411).
The practical point: a buyer or lender who checks the record and sees nothing can generally rely on that. A claim that was never recorded may lose out to someone who bought without knowing about it. Each state writes its own recording rule, and the wording differs, so this is Arizona's version, not a national one.
This is also why a title search starts at the recorder. The record is where a prior owner, a mortgage or a lien shows up. See how to do a title search for the full method.
What does a county recorder not do?
The recorder files documents. It does not guarantee them. Three limits cause most of the confusion.
First, a recorded document is not a verified document. Arizona's rule on form lists what a recorder may reject, such as a missing caption, a missing original signature or an illegible page, and then says an accepted instrument "is not subject to a later claim of invalidity for failure to comply with the requirements of this section" (Arizona Revised Statutes 11-480). That addresses form rules only. It does not make a forged or defective deed good.
Second, indexing follows the caption. In Arizona the recorder has "no obligation to index any instrument under any subject index category" unless the document's caption includes it. A document can be on file yet hard to find if it was captioned unusually.
Third, the recorder does not give legal advice, resolve ownership disputes, or insure anything. For the difference between a search and a policy, read title search vs title insurance.
Recorder vs assessor vs clerk vs treasurer: who does what?
A property touches several county offices, and each keeps different records. Mixing them up sends people to the wrong website. The table uses the Maricopa County (Arizona) offices as the example, with notes on how other places divide the work.
| Office | Main job | What you find there | Example |
|---|---|---|---|
| Recorder | Records and indexes documents | Deeds, mortgages, releases, liens, plats | Maricopa County Recorder (Arizona) |
| Assessor | Identifies parcels and sets values for tax | Parcel number, valuation, classification, exemptions, parcel maps | Maricopa County Assessor |
| Treasurer | Bills and collects property tax | Tax amounts due, payment status, delinquent taxes, tax liens | Maricopa County Treasurer |
| Clerk | Varies by state | In Harris County, Texas and Cook County, Illinois the clerk also keeps the land records; elsewhere it handles courts or elections | Harris County Clerk; Cook County Clerk |
How do the assessor and treasurer differ from the recorder?
The Maricopa County Assessor describes a valuation role: it states that it "annually notices and administers over 1.8 million real and personal property parcels and accounts" (Maricopa County Assessor). Its site offers parcel maps, appeals and exemptions, which are tax valuation topics, not deed topics.
The Maricopa County Treasurer's stated mission is "billing, collection, investment, and disbursement of public monies" for taxing districts, the county and school districts (Maricopa County Treasurer). Its site lets you pay property taxes and look up tax information by parcel, name or address.
So the order is: the assessor says what the parcel is worth for tax, the treasurer collects the tax, and the recorder holds the paper trail of who owns the parcel and who has claims on it. A deed will not show a tax value, and a tax bill will not show a mortgage. For Maricopa specifics, see our Maricopa County title search page and the Maricopa County lien search guide.
How are recorded documents indexed and searched?
Most offices let you search by the names of the parties, the parcel, the document type and the recording date. The Cook County Clerk says recorded land records "can be retrieved by searching for PIN, grantor, grantee, and by other indexed detail." A PIN is the parcel identification number. The grantor is the person giving title, and the grantee is the person receiving it.
Harris County, Texas shows how detailed an index can be. Its real property search form has fields for file number, film code, grantor, grantee, trustee, subdivision, instrument type, volume, page, section, lot and block (Harris County Clerk, Real Property search). It states that images are available from 11/1/1960 and that after a document is processed, it may take "1 to 2 business days" to show up in the online search.
It also warns that the online database "does not constitute the official repository of real property records." Online search is an index to the record, not the record itself, and some older documents will not be there.
New York City works the same way with a different name. The Department of Finance says ACRIS lets you search property records and view document images for Manhattan, Queens, the Bronx and Brooklyn from 1966 to the present, and find a property's borough-block-lot (BBL) number (NYC Department of Finance, ACRIS). Our guides to how to read ACRIS and what a BBL is go further. Philadelphia's Department of Records says it "records real estate documents in Philadelphia" and provides public access to land records (Philadelphia Department of Records).
How do you search a county recorder's office?
Find the right office
Search the county name plus "recorder," "county clerk," "register of deeds" or "department of records." The office that records deeds is the one you want, not the assessor or treasurer.
Start with the parcel number or the owner name
The assessor's parcel search gives you the parcel number and the current owner name. Searching the recorder by parcel is tighter than by name, because common names return unrelated people.
Search by document type and date range
Pull deeds first to build the ownership order, then mortgages, releases and liens. Compare each mortgage with a later release or satisfaction for the same lender.
Open the document image
The index entry only summarizes. Open the image to read the legal description, the signers and any referenced earlier documents.
Note the date coverage
Online images often begin in a particular year, such as 1960 in Harris County or 1966 in ACRIS. Older documents may require an in-person or mail request.
What a recorder search cannot show
Where does a recorder search fit in a HeritageDeed report?
HeritageDeed pulls from the official county record in the places it serves, and the recording office is the core source in each. Examples include Maricopa County, Arizona, Harris County, Texas, Cook County, Illinois and Philadelphia, Pennsylvania. Prices are $49 for a Current Owner Search, $79 for a Two Owner Search and $129 for a 30-Year Search, in the counties listed on /title-search.
Key takeaways
Key takeaways
- A county recorder's office receives, stamps, stores and indexes real estate documents in the order received.
- Recording gives public notice, but the office does not check whether a document is valid.
- The assessor values property for tax and the treasurer collects the tax. Neither keeps the deed record.
- The office name varies: recorder, county clerk, register of deeds, department of records or city register.
- Online indexes are a guide to the record and may be delayed or incomplete, so open the document image.
Frequently asked questions
- What does a county recorder's office do?
- It accepts real estate documents such as deeds, mortgages, liens and plats, records them in the order received, and indexes them for public search. In Arizona the recorder has custody of all records, maps and papers deposited in the office. It does not decide who owns a property.
- What is the difference between a county recorder and a county assessor?
- The recorder files and indexes ownership and lien documents. The assessor identifies parcels and sets the value used for property tax. In Maricopa County, the assessor handles parcel maps, appeals and exemptions, while deeds and mortgages are recorded with the recorder.
- Is the county recorder the same as the county clerk?
- Sometimes. In Harris County, Texas and Cook County, Illinois, the clerk keeps the land records. In Arizona there is a separate county recorder. Names and duties are set by state law, so check the county website for who records deeds where the property sits.
- Does the recorder collect property taxes?
- No. The treasurer bills and collects property tax in places like Maricopa County, where its stated mission is billing, collection, investment and disbursement of public monies. The recorder only records documents, though a tax lien document may appear in the recorded record.
- Can anyone search recorded documents?
- Generally yes. Land records are public. Cook County says recorded land records can be retrieved by PIN, grantor, grantee and other indexed detail. Some personal data, such as full Social Security numbers, may be redacted, and online systems may not hold every older document.
- How long does it take for a recorded deed to show up online?
- It varies by county. Harris County states it may take 1 to 2 business days after a document is processed for it to appear in the online search. A deed that is recorded but not yet indexed online will be missed by a same-day search.
- Does recording a deed prove that I own the property?
- No. Recording gives public notice and sets priority, but the office does not verify the deed. Accepted documents are shielded from later claims of invalidity only for form defects. A forged or defective deed can still cause title problems, which is what title insurance addresses.
- What can a recorder reject?
- It depends on state law. Arizona lets a recorder reject an instrument that lacks a caption, original signatures, legibility or required size and type. A document that meets the form rules is accepted without the recorder reviewing the deal behind it.
