Legal Description vs Street Address
By AcreBound Editorial Team Updated:
Quick Answer
A street address tells people where to find a property. A legal description defines exactly which land is owned, sold or mortgaged, and it generally controls if the two conflict. The APN is the county’s ID number for the parcel.
Rules differ by state, so check a contract with a title company or attorney.
A street address tells people where to find a property. A legal description tells a court, a lender or a title company exactly which land is being owned, sold or mortgaged. In a deed, the legal description is what defines the land. The address is a convenient label. A third identifier, the APN, is the county's number for the parcel.
Three Ways to Identify the Same Land
| Street address | APN | Legal description | |
|---|---|---|---|
| What it is | A location for mail and emergency services | The county's ID for a parcel | A precise written definition of the land |
| Example | 123 Maple Street | 123-456-789 | Lot 12, Block 4, Willow Creek Estates… |
| Who assigns it | City or county addressing office | County assessor | Drafted from a survey or plat and recorded in deeds |
| Can it change? | Yes, such as when a street is renamed | Sometimes, such as when a parcel is split or merged | Only by a new recorded document |
| Always exists? | No, vacant land often has none | Yes, for taxed parcels | Yes, for any land that can be conveyed |
| Defines the boundary? | No | No | Yes |
| Used on | Mail, listings, navigation | Tax bills, county records, parcel search | Deeds, mortgages, title insurance |
Which One Governs?
A deed conveys the land that its legal description describes. If the address on a contract is wrong but the legal description is right, the legal description generally controls. That's why title companies and attorneys check it carefully. Some states write this into statute. Colorado's law on title documents says that if a street address or parcel number creates any variance or ambiguity, the legal description of the property governs. The same statute requires title documents to carry the street address, when one is displayed on the property, as an aid to identification, and says a document without an address isn't ineffective if the legal description is there.
Most states handle this their own way, so a legal question about a specific document should go to a local professional.
Title industry practice follows the same logic. A Michigan title association training deck explains that registers of deeds don't officially catalogue land by address. They catalogue it by legal description, and addresses can be misleading.
When They Don't Line Up
- One address, several parcels. A house and an extra lot or a garage may have separate legal descriptions and APNs.
- One address, part of a bigger parcel. A shop in a shopping center or a unit in an apartment complex may have its own address on a parcel the county recorded as one large property.
- A parcel with no address. Vacant and rural land is typically identified by its APN and legal description only. See How to Find a Property That Has No Street Address.
- The address changed. A renamed road or a renumbering doesn't change the legal description or the APN.
- The address is on a different street. A corner house may be numbered on one street while its driveway or legal frontage is on another, so a search may land on a neighboring parcel.
- Two addresses, one building. The lien-filing company Levelset points to the New York Stock Exchange: known as 11 Wall Street, but also listed in Manhattan records as 2 Broad Street.
How to Get From an Address to the Legal Description
- Look up the address in the county assessor's or GIS viewer. It gives you the APN and usually a short version of the legal description. See How to Find the APN for a Property.
- Check that the parcel is the one you mean. Match the acreage, the shape and the neighbors. A wrong match here carries into every later step.
- Pull the recorded deed from the county recorder. Search by the owner's name or by the recording reference on the assessor's page. The deed carries the full description.
- Compare the two. If the assessor's text and the deed differ, the recorded deed is the one to trust. A title company's report will show the description it insures.
Which to Use for What
- Finding a property: the address, or the APN if there is no address.
- Looking up taxes and records: the APN. See How to Find the APN for a Property.
- Buying, selling or mortgaging: the legal description, which the title company or attorney handles.
- Hiring a contractor who may need to file a lien, or filing one yourself: the legal description. Levelset reports that 11 states require the full legal description on a mechanics’ lien claim. Check your state's rule.
- Researching boundaries: the parcel map for a quick look, and the plat or survey for details.
Frequently Asked Questions
Can I use my address instead of a legal description?
For a deed, mortgage or title policy, no. The address can appear as a supplement, but the legal description has to carry the weight. For finding the place or mailing the tax bill, the address is fine.
Does the legal description change when the address changes?
No. A renamed street or new house number leaves the legal description alone. It changes only through a new recorded document, such as a survey-based split or a boundary adjustment.
Is the APN the same as the legal description?
No. The APN is a tax ID that points to a record. It can change if the parcel is split or combined. See APN vs Parcel ID for the naming differences between counties.
Where do I find the legal description if I only have an address?
Start at the county assessor's parcel page, then confirm against the recorded deed or a title report.
Common Mistakes
- Assuming one address means one parcel.
- Using an address as the only identification in a land contract.
- Assuming that a changed address means that a different property is described.
- Skipping the check that the APN, the address and the legal description point to the same land.
