Definition
Heirs of the body are the lineal descendants of a named person — children, grandchildren, and further issue — who are qualified by law to inherit from that person. The phrase excludes collateral relatives (siblings, cousins, aunts, uncles) and, historically, excluded adopted children and illegitimate children, confining inheritance to blood descendants in the direct line.
The phrase carries significant technical weight in property law. When used in a deed or will to define who takes after a life tenant, it traditionally invoked the fee tail — a form of estate that locked land in the bloodline and prevented the current holder from alienating it to strangers. Under the common law rule in Shelley's Case and the doctrine of estates in fee tail, a grant "to A and the heirs of his body" did not simply identify future beneficiaries; it created a specific estate with defined legal consequences.

Common Confusion
HEIRS OF THE BODY vs. CHILDREN: These are not interchangeable, and courts have consistently treated them as distinct. "Children" refers to the first-generation descendants only — the immediate offspring of a named person. "Heirs of the body" sweeps more broadly, capturing all qualifying lineal descendants who survive to inherit, including grandchildren and beyond if closer descendants have predeceased. Substituting one term for the other in a drafting context can produce radically different outcomes for the disposition of property across generations.
HEIRS OF THE BODY vs. NATURAL HEIRS: Black's notes that courts have treated "natural heirs" and "heirs of the body" as carrying the same legal import in certain testamentary contexts. This equivalence is not universal and depends on jurisdiction and the instrument's overall language. Researchers should not assume the terms are always synonymous.
HEIRS OF THE BODY vs. ISSUE: "Issue" is the broader modern term for lineal descendants and has largely displaced "heirs of the body" in contemporary drafting. The two terms generally point to the same class of persons, but "issue" carries fewer feudal-era connotations and is less likely to trigger fee tail analysis in jurisdictions that have not fully abolished that doctrine.

Why It Matters in Research
This phrase is a historical tripwire. It appears throughout pre-20th-century deeds, wills, and settlement documents as the technical trigger for fee tail estates — and its presence in an instrument often signals a legal dispute about alienability, entailment, or remainder interests. Researchers working in colonial-era records, 19th-century land conveyances, or older trust instruments must recognize that "heirs of the body" was not merely descriptive language; it was operative language with consequences that depended entirely on whether the jurisdiction recognized fee tail estates.
Most American states abolished the fee tail by statute, converting fee tail estates into fee simple estates or life estates with remainder to the heirs of the body. The timing and method of abolition varied by state, which means the same phrase in an 1820 deed can mean something legally different depending on whether it was executed in Virginia, Massachusetts, or Pennsylvania. Any corpus research involving land records must account for the applicable state abolition statute and its effective date.
A second research trap: in wills, courts have sometimes departed from the strict technical meaning and construed "heirs of the body" as a description of the testator's intended beneficiary class rather than as an estate-creating term. Context — particularly whether the instrument is a deed or a will, and whether the grant is of a present interest or a future executory interest — shapes how courts interpret the phrase. Bouvier's flags this directly, noting that the technical meaning applies more reliably in deeds than in wills, where intent may override strict construction.
The distinction from "children" is a recurring issue in probate litigation. When a testator used "heirs of the body" to designate remainder beneficiaries, courts faced questions about whether grandchildren took if a child predeceased the life tenant. The answer turned on whether the court applied the technical multi-generational meaning or collapsed the phrase into a synonym for "children."

Historical Dictionary Support
Black's and Bouvier's converge on the core definition — lineal descendants qualified to inherit — but each illuminates a different dimension. Black's emphasizes the equivalence with "natural heirs" in the testamentary context, which is a useful navigational point for will construction cases. Bouvier's is more precise on the deed/will distinction, noting the "well settled" divergence between "heirs of the body" and "children," and grounding the definition in the inheritance qualification: such of the issue "as may by law inherit."
Neither historical source directly addresses the fee tail implications in depth, which is a significant gap. The phrase's most consequential legal operation — triggering entailment in common law grants — is left implicit. Researchers relying solely on dictionary definitions will miss that the phrase's real legal force lay in its estate-creating function, not merely its identification of a beneficiary class. Treatises on real property and the historical literature on fee tail abolition are necessary supplements to these dictionary entries.

Jurisdictional Note
The operative effect of "heirs of the body" in deeds differs by state based on when and how each jurisdiction abolished the fee tail. Several states converted fee tail grants into fee simples; others created a life estate in the grantee with remainder to the heirs of the body as purchasers. In a small number of states, fee tail estates were never fully recognized. Researchers must identify the controlling abolition statute and its date before interpreting an instrument containing this phrase.

Escheat — When Property Passes to the State for Lack of Heirs (Law Mind Trusts, Estates & Probate Encyclopedia): Directly relevant. When an estate conditioned on heirs of the body fails because no qualifying descendants survive, the property may escheat to the state — making the definition of this phrase a threshold question in escheat analysis.
