Definition
A personal disability is a legal incapacity or limitation on a person's ability to act, sue, or be sued in law, arising not from some external defect in the matter at issue, but from the particular legal status or condition of the individual. The disability is said to be "personal" because it attaches to the person rather than to the subject matter of a transaction or claim.
Classic examples from common law include:
1. Coverture — a married woman's legal identity was absorbed into her husband's, disabling her from contracting, holding property, or suing independently.
2. Infancy (minority) — a person under the legal age of majority lacked full capacity to bind themselves by contract or to sue without a guardian or next friend.
3. Lunacy or mental incapacity — a person adjudged mentally incompetent was disabled from performing a range of legal acts.
4. Alienage — in certain historical and jurisdictional contexts, a non-citizen's ability to own land or maintain certain legal actions was restricted.
The disability suspends or limits legal capacity; it does not ordinarily destroy the underlying right. When the disability is removed — by reaching majority, by restoration of competency, by death of a spouse under coverture — the person typically regains full legal standing, and statutes of limitations that were tolled during the disability begin to run.

Common Language
Modern common usage (Wiktionary): A physical or mental condition that limits a person's movements, senses, or activities.
Historical common usage (Webster's 1913): "Want of legal qualification to do a thing; incapacity; inability; disqualification."
The gap here is significant. In ordinary modern usage, "disability" almost always means a physical or mental impairment affecting daily life — the sense codified in the Americans with Disabilities Act and the Social Security Act. In classical legal usage, "personal disability" means something narrower and structurally different: a status-based incapacity imposed by law on a category of persons, irrespective of physical or cognitive condition. A perfectly healthy married woman under coverture was "personally disabled" in law. A researcher encountering the phrase in historical sources must resist reading modern disability law concepts backward into the older terminology.

Common Confusion
Personal disability is frequently encountered alongside — and confused with — two related distinctions:
Personal disability vs. real disability: A "real disability" (also called a disability in rem) is a defect or incapacity attaching to a thing, a title, or a right — not to the person. A clouded title is the disability of the property. A personal disability is the disability of the claimant.
Personal disability vs. civil disability: Civil disabilities (loss of voting rights, right to hold office, or right to contract following a criminal conviction) are sometimes treated as a subset of personal disabilities and sometimes distinguished from them. Historical sources are inconsistent. The categories overlap in older treatises and should not be treated as mutually exclusive without examining the specific source.
Personal disability in law vs. disability in modern regulatory and benefits contexts: The ADA, the Social Security Act, and VA compensation law each define "disability" on their own statutory terms. None of those definitions maps cleanly onto the historical common law concept of personal disability. Using the term in a research context without specifying which framework applies will produce confusion.

Why It Matters in Research
The phrase "personal disability" is a term of art in historical legal sources that will mislead researchers who approach it through a modern lens. Three navigational points:
First, tolling of statutes of limitations: The most practically significant surviving use of "personal disability" in American law is in limitations doctrine. Most jurisdictions toll (pause) the running of a limitations period during a plaintiff's legal disability — infancy, incompetency, and sometimes imprisonment. Older cases and some statutes use "personal disability" as the category label for these tolling conditions. Researchers working on limitations questions must identify what the governing statute lists as qualifying disabilities, because the list varies by jurisdiction and era.
Second, coverture's disappearance: Coverture has been abolished in all U.S. jurisdictions, but cases and statutes from before the Married Women's Property Acts (passed in most states between the 1840s and 1890s) treat it as a standard personal disability. A researcher reading 19th-century case law on contract capacity, property rights, or limitations tolling must account for this abolished disability category.
Third, the term does not appear in modern statutory codifications under this name. Modern law addresses the underlying conditions (minority, incompetency) under those specific terms, or under the broader umbrella of "legal incapacity." Searching for "personal disability" as a legal concept in post-20th-century materials will return almost exclusively benefits and employment discrimination law — a different animal entirely.

Historical Dictionary Support
Black's Law Dictionary defines personal disability as an "inability or incapacity for legal action resulting from the status or condition of the particular person, such as coverture, infancy, or lunacy." This is the core classical definition and has remained stable across editions that treat the concept. Black's correctly centers the definition on status-based incapacity and gives the canonical examples.
What historical dictionaries leave underexplained is the relationship between personal disability and the tolling of limitations periods — which is, in practice, the context where the term most often appeared in litigation. The definition is accurate but static; it does not capture how courts applied the concept to determine when a disability began, when it ended, and whether multiple overlapping disabilities extended the toll cumulatively or only to the longest single period. Those questions were heavily litigated and answered differently across jurisdictions.
Historical sources also do not account for the gradual abolition of the most prominent personal disabilities. Coverture's elimination and the standardization of the age of majority remove two of the three examples Black's offers. The concept has contracted significantly in scope, even if the doctrinal framework persists in limitations law.

Jurisdictional Note
Limitations tolling for personal disability is almost universally recognized but defined differently by statute in each jurisdiction. The qualifying disabilities, the point at which the disability is deemed to begin and end, and whether the toll applies to defendants as well as plaintiffs vary. Researchers must consult the specific jurisdiction's limitations statute and its judicial interpretation, not a general common law rule.

Encyclopedia Cross-Reference
Social Security Disability — Definition of Disability and the Five-Step Sequential Evaluation (The Law Mind Administrative Law & Government Encyclopedia): Covers the modern regulatory definition of disability under federal benefits law — a separate framework from the common law concept, but essential context for distinguishing the two.
VA Disability Compensation — Service Connection, Disability Ratings, and the Combined Rating System (The Law Mind Military, Veterans & Admiralty Law Encyclopedia): Another distinct statutory framework for disability, relevant when research touches veterans' claims.
Credit for Elderly and Disabled (The Law Mind Tax Encyclopedia): Tax treatment of disability status — again a separate statutory definition.
