What is a Legal Description?
A legal description is the precise way a parcel of real property is identified in deeds, mortgages, and other legal documents. Unlike a street address (which is a postal convenience), a legal description defines the exact boundaries of a property using one of several standardized systems. Every deed recorded with the county contains a legal description, and it is the legal description -- not the street address -- that determines what you actually own.
Street addresses can be ambiguous (a large property might span multiple addresses) or change (cities occasionally renumber streets). Legal descriptions are permanent and precise. They tie directly to recorded plat maps, surveys, or government survey reference points that define exact boundaries down to the foot or even the inch.
Types of legal descriptions
Three systems are used in the United States. The lot-and-block system is the most common for properties in subdivisions. The description references a lot number, block number, subdivision name, and the recorded plat: "Lot 14, Block 3, Willowbrook Section 2, Harris County, Texas." The plat, filed with the county, contains the exact dimensions and boundaries. This system is simple, readable, and used for most residential properties.
The metes and bounds system describes the property boundary by tracing its perimeter using compass directions and distances from a defined starting point. This is the oldest system and is used for older properties, rural land, and irregularly shaped parcels that don't fit into a platted subdivision. Metes and bounds descriptions can be lengthy and complex but are legally precise.
The government survey system (also called the rectangular survey or Public Land Survey System) divides land into townships, ranges, and sections based on principal meridians and baselines. A typical description reads "the NW 1/4 of Section 12, Township 3 South, Range 2 East." This system is used primarily in states west of the Mississippi and is common for agricultural and rural properties. Texas does not use this system -- it uses its own historical land grant system based on metes and bounds.
Why legal descriptions matter for investors
Legal descriptions matter because they define exactly what you're buying. A mistake in the legal description can result in purchasing the wrong property, gaps or overlaps between adjacent parcels, title insurance claims, and difficulty selling or refinancing. When reviewing a contract, verify that the legal description matches the intended property. The title company will verify this during the title search, but catching errors early saves time and prevents closing delays.
For wholesalers, the legal description in your purchase contract must exactly match the legal description in the seller's deed. Any discrepancy creates a cloud on title that must be resolved before closing. Copy the legal description from the seller's most recent deed rather than typing it from memory or using the tax records, which sometimes contain abbreviated or incorrect descriptions.
