Definition
Retention has several distinct legal meanings, each operating in a different doctrinal context. Researchers should identify which meaning applies before pursuing historical sources, as the historical dictionaries address only one of them.
1. Lien by retention (Scots law). The right of a person in possession of another's property to withhold that property until a debt owed by the property's owner is satisfied. Functionally equivalent to a lien. Bouvier distinguishes between general retention — the right to detain any property of a debtor for any balance due — and specific retention — the right to hold a particular item until a claim directly related to that item is paid.
2. Employee retention. In employment and tort law, an employer's decision to keep an employee in a position after acquiring knowledge, actual or constructive, of that employee's unfitness or dangerous propensity. Negligent retention is the failure to act on that knowledge, exposing the employer to liability for harm the employee subsequently causes.
3. Document retention. The preservation of records — physical or electronic — by an organization, typically governed by statute, regulation, or internal policy. Document retention obligations intersect with discovery, spoliation doctrine, and regulatory compliance. A retention schedule sets the minimum period records must be kept before lawful destruction.
4. Self-insured retention (SIR). In insurance law, the dollar amount an insured must pay out of pocket before the insurer's coverage obligation is triggered. Structurally similar to a deductible but with important differences in how the insurer's duty to defend activates.

Common Language
Modern common usage (Wiktionary): The act of retaining or something retained; the act or power of remembering; in medicine, involuntary withholding of bodily functions; in behavioral health, the length of time a patient remains in treatment.
Historical common usage (Webster's 1913): The act or state of retaining; the power of retaining; the act of withholding; a place of custody or confinement.
The common English word maps loosely onto all four legal uses — retaining property, retaining employees, retaining records, retaining risk. This surface similarity is a research trap. A historical source using "retention" almost certainly means the Scots-law lien concept (definition 1 above). A modern secondary source using the same word may mean negligent employment practices, insurance risk allocation, or records management. Context must be established before the source is useful.

Recognized Forms
/SUBTYPES
General retention (Scots law): The right to detain any property of a debtor for any general balance of accounts owed, not limited to a claim arising from the specific property held.
Specific retention (Scots law): The right to hold a particular item of property until a claim arising specifically from or against that item is satisfied.
Negligent retention (tort): Employer liability arising from the failure to remove or reassign an employee known to pose a foreseeable risk of harm to others.
Document retention / records retention: The obligation to preserve records for a defined period under statute, regulation, litigation hold, or internal policy.
Self-insured retention (SIR): The insured's retained layer of financial responsibility below the insurer's coverage threshold.

Why It Matters in Research
The historical dictionaries are unanimous but narrow. Every historical source — Black's, Rapalje & Lawrence, Bouvier, Burrill — treats retention as a Scots-law lien concept and nothing more. A researcher who enters this corpus expecting guidance on negligent retention in employment law, document retention obligations, or self-insured retentions in insurance contracts will find nothing directly applicable. That gap is not an omission to be corrected; it reflects that the other modern uses of the term developed outside the common-law tradition these dictionaries catalog, or developed later.
For negligent retention research, the relevant modern doctrine is grounded in tort principles of employer liability and foreseeability, not in any historical property-law analog. The connection to the Scots lien concept is linguistic only.
For document retention, statutory and regulatory sources — not common-law dictionaries — govern. The period after which documents may be destroyed varies by jurisdiction, record type, and applicable federal or state regulation. Litigation holds can override any retention schedule, and spoliation doctrine becomes the operative framework once litigation is reasonably anticipated.
For self-insured retentions in insurance, the distinction between an SIR and a deductible matters because courts have split on whether a carrier's duty to defend activates before or after the SIR is exhausted. Researchers should not assume these terms are interchangeable; insurance policy language controls, and the historical dictionaries offer no guidance here.
The Scots-law lien use remains relevant in comparative law research and in tracing the conceptual ancestry of possessory liens in American and English common law, where the historical sources are genuinely useful.

Historical Dictionary Support
The five historical sources agree on substance. Retention in Scots law is a possessory right — the right to hold another's property until a debt is paid — and all four active sources (Black's 1st and 2nd Ed. are essentially identical on this point) equate it explicitly with a lien. Burrill is the most concise, simply cross-referencing to Lien. Bouvier adds the most doctrinal texture, drawing the general/specific distinction that no other source fully articulates.
Rapalje & Lawrence broadens the concept slightly, noting that retention can apply to withholding a debt (not just physical property) as well as retaining property. This aligns with Bouvier's general retention and suggests the concept had some flexibility beyond strictly possessory situations.
None of the historical sources address the modern employment, records management, or insurance uses of the term. This is not a deficiency in the sources — those uses were either not yet developed or not understood as legal terms of art when these dictionaries were compiled. Researchers should treat the historical entries as authoritative for the Scots-law lien concept and irrelevant to the other three definitions.

Jurisdictional Note
The Scots-law lien concept of retention does not map directly onto American or English common-law possessory lien doctrine, though the functional similarity is close. Researchers working in American courts should use lien and its recognized subtypes rather than relying on retention as a term of art. In insurance, the SIR terminology is standard in American commercial practice but may appear differently in English or other common-law market policies.
