Definition
The proportionate reduction applied to pecuniary legacies when the estate's assets are insufficient to satisfy all bequests in full. When a testator leaves more in monetary gifts than the estate can pay — after debts, expenses, and prior claims are settled — legatees do not receive their full designated amounts. Instead, each legatee's gift is reduced pro rata so that the available funds are distributed equitably among those entitled to share them.
The doctrine operates as a rationing mechanism: no single legatee is paid in full at the expense of others in the same class. The reduction falls on the legatees collectively, in proportion to the size of each bequest.
Common Confusion
Abatement among legatees is one application of the broader doctrine of abatement in the law of wills and estates. The broader doctrine also governs the order in which different categories of testamentary gifts — specific bequests, general legacies, demonstrative legacies, and residuary gifts — are reduced before others are touched. Abatement among legatees addresses what happens within a class once that class is reached: the pro rata sharing of a shortfall. Researchers should not conflate the intra-class mechanics described here with the inter-class priority rules that determine which category of gift abates first. The two questions are sequential: first, which class abates; second, how the reduction is distributed within that class.
Why It Matters in Research
The central research trap is treating abatement among legatees as a self-contained rule when it is actually the final step in a two-stage analysis. Historical sources, including Burrill, define the term narrowly — the proportionate reduction within a class — without always making explicit that the inter-class abatement order must be resolved first. A researcher reading only the dictionary entry could miss that general legacies typically abate before specific bequests, and that abatement among legatees governs only after the applicable class has been identified.
The Latin cross-reference in Burrill — defalcatio — signals that some older English and American equity sources may index this doctrine under that term rather than under abatement. Searches in historical equity reports and chancery records should include defalcatio as an alternate search term, particularly in materials predating the mid-nineteenth century.
Jurisdictional variation in the statutory treatment of abatement order affects how often this doctrine becomes contested in modern practice. In states with detailed non-testamentary succession statutes or elective share regimes, the pool available for legatees may be further reduced before abatement among legatees even applies, compressing the practical significance of the pro rata rule. Researchers working with twentieth- and twenty-first-century materials should verify whether the jurisdiction has codified abatement order, as statutory schemes sometimes alter the common law sequence.
The doctrine surfaces in three distinct research contexts: equity jurisprudence (the historical home of legacy enforcement), probate court proceedings (the modern procedural setting), and drafting literature (where testators and counsel attempt to override the default abatement rules by specifying priority or directing that certain gifts be paid first). Each context has its own primary source literature, and researchers should not assume that cases from equity courts translate directly to modern statutory probate frameworks.
Historical Dictionary Support
Burrill's definition is precise and serviceable: a proportionate reduction of pecuniary legacies when assets are insufficient to pay them in full. The entry's authority citations — Fonblanque's Equity, Ward on Legacies, Story's Equity Jurisprudence, and Blackstone's Commentaries — situate the doctrine firmly in the English equity tradition, where courts of chancery supervised the administration of legacies and enforced the rights of legatees against executors. The Bracton citation (fol. 61a) reaches further back into the common law foundation, suggesting the underlying principle of proportionate reduction predates the equity courts' elaboration of it.
What Burrill's entry does not address is the relationship between abatement among legatees and the broader classification of legacies that governs which gifts abate first. Story's Equity Jurisprudence, cited by Burrill, provides considerably more analytical structure on this point and is the more useful primary source for researchers who need to reconstruct the full doctrine rather than the narrow definition.
The term defalcatio noted in Burrill's headnote deserves attention. It reflects the Latin-inflected vocabulary of equity pleading and suggests that early American practitioners trained in equity would have recognized the concept under either term. Modern sources have largely abandoned defalcatio in favor of plain-English descriptions.
Jurisdictional Note
Most American jurisdictions have codified abatement rules in their probate or estates statutes, often following the framework of the Uniform Probate Code, which specifies the order in which testamentary gifts abate and addresses pro rata reduction within classes. The common law doctrine remains relevant where statutes are silent, where the will itself purports to vary the default order, or in interpreting older instruments governed by pre-codification law.
