Definition
Enitia pars (Latin: "the share of the eldest") is a historical English common law term denoting the portion or lot selected by the eldest coparcener upon a voluntary partition of inherited land among coparceners. When heirs — typically daughters, in the absence of male heirs — jointly inherited an estate as coparceners and chose to divide it among themselves, the eldest was entitled to make the first selection of her share. That right of first choice, known as primer election, was the practical content of enitia pars. The maxim associated with the rule, as recorded in Coke on Littleton, states: Enitia pars semper preferenda est propter privilegium statis — "the part of the elder sister is always to be preferred on account of the privilege of age."
The doctrine carried no additional entitlement to a larger share; all shares were presumed equal in value. The privilege lay solely in the right to choose first, which in practice conferred advantage where parcels of land differed in quality, location, or convenience.
Common Confusion
Enitia pars is sometimes loosely associated with primogeniture, but the two doctrines are distinct. Primogeniture gave the eldest son the entire inheritance to the exclusion of all others. Enitia pars arose only in coparcenary — a form of joint inheritance that existed precisely because there was no male heir capable of taking by primogeniture — and it granted the eldest coparcener only the privilege of first selection, not the whole estate. The terms should not be used interchangeably.
Why It Matters in Research
Enitia pars is a term researchers will encounter almost exclusively in historical English property law sources, particularly materials dealing with coparcenary, partition, and the inheritance rights of female heirs before the sweeping property law reforms of the nineteenth century. It surfaces in Coke on Littleton and related treatise literature, but is effectively absent from modern statutory or case law.
Several navigational points are worth noting:
First, the doctrine is inseparable from coparcenary as a legal category. Researchers unfamiliar with the technical definition of coparcenary may misread passages invoking enitia pars, confusing the context with ordinary tenancy in common or joint tenancy.
Second, the privilege applied only to voluntary partition. Compulsory or court-ordered partition did not necessarily trigger the same rule of elder preference, and sources do not always make this condition explicit.
Third, the term appears in early American legal writing because English common law — including coparcenary doctrine — was received into the colonies and, to varying degrees, the early states. Some American treatises reproduced the enitia pars rule directly. Researchers working in early American property law should be alert to this carryover even where local statutes had already modified or abolished the underlying coparcenary framework.
Fourth, the obsolescence of the term is itself informative. Its disappearance from legal usage tracks the legislative dismantling of sex-based inheritance rules and the replacement of coparcenary with statutory schemes of intestate succession treating all children equally. A source that uses enitia pars as living law — rather than historical description — is almost certainly pre-nineteenth century, which can help date undated manuscripts or determine the vintage of a treatise.
Historical Dictionary Support
Both editions of Black's Law Dictionary define enitia pars consistently as "the share of the eldest," situating it as a term of English law. The second edition is the more complete of the two, supplying the associated maxim with its citation to Coke on Littleton at folio 166, and explicitly identifying the right of first choice — primer election — as the operative privilege. The first edition's entry is truncated in the available source material but aligns with the same core meaning.
Neither edition contextualizes the doctrine within the broader history of coparcenary or explains its obsolescence, which is consistent with Black's historical practice of defining terms without extended commentary on their practical currency. Researchers should not infer from the dictionary entry alone that the term carried ongoing legal significance at the time of publication.
Jurisdictional Note
Enitia pars is a doctrine of English common law and has no meaningful independent existence in modern American, Canadian, or Commonwealth jurisdictions. Where it appears in American sources, it reflects the early reception of English common law and should be read against the backdrop of each jurisdiction's specific reception statutes and subsequent property law reforms.
