Definition
A parol lease is a lease of real property created by oral agreement rather than by written instrument. The parties agree to the terms — duration, rent, possession — by spoken words alone, leaving no signed writing to evidence the arrangement. Subject to statutory exceptions, a parol lease is legally valid and enforceable, but its enforceability is sharply constrained by the Statute of Frauds, which in most jurisdictions requires leases exceeding one year to be in writing. A parol lease for a term of one year or less generally remains fully effective at common law.

Common Language
Modern common usage (Wiktionary): "Parol" means oral or verbal; by word of mouth rather than in writing.
Historical common usage (Webster's 1913): "Parol" — by word of mouth; oral; as opposed to written; used especially in law to distinguish oral evidence or agreements from written instruments.
The common meaning of "parol" is essentially continuous with the legal meaning. The research trap lies not in the word itself but in the compound term: a parol lease is not simply an informal lease or a handshake deal in the colloquial sense. It is a recognized legal category with defined enforceability rules tied specifically to duration and statutory requirements. Researchers who treat "parol" as merely meaning "casual" or "unenforceable" will misread sources that acknowledge the parol lease as valid.

Common Confusion
PAROL LEASE vs. VOID LEASE: A parol lease is not automatically void or unenforceable. At common law, short-term oral leases were fully enforceable. The Statute of Frauds imposes a writing requirement only for leases beyond a specified duration (commonly one year). Many historical sources characterize parol leases in ways that imply invalidity; this overstates the rule. A parol lease for a term within the statutory limit creates genuine legal obligations between landlord and tenant.
PAROL LEASE vs. TENANCY AT WILL: Where a parol lease purports to create a term longer than the Statute of Frauds permits without writing, the tenant's entry under it often gives rise to a tenancy at will or, after rent payment, a periodic tenancy — not a nullity. Historical courts frequently converted unenforceable parol leases into these recognized tenancies rather than voiding all arrangements.
PAROL vs. PAROLE: An unrelated term. "Parol" (one word, no terminal "e" in legal usage, though historical spelling varies) means oral or verbal. "Parole" refers to conditional release from incarceration or a prisoner of war's pledge. Rapalje & Lawrence run PAROL LEASE and PAROLE as consecutive entries, a juxtaposition that has confused researchers scanning historical dictionaries.

Why It Matters in Research
The Statute of Frauds is the central variable. The original English statute (29 Car. II, c. 3, §§ 1–2, 1677) required leases for more than three years to be in writing; American jurisdictions adopted varying thresholds, most commonly one year. When reading historical American cases or treatises, the applicable duration threshold determines whether a parol lease was enforceable — and that threshold is jurisdiction-specific and era-specific. A researcher reading a Massachusetts case from 1810 or a New York case from the 1830s (see Rapalje's citations: 12 Mass. 134; 15 Wend. (N.Y.) 99) must identify the local statutory rule before drawing conclusions about outcome.
Part performance is a second major variable. Courts of equity routinely enforced otherwise void parol leases where the tenant had entered possession, paid rent, or made improvements in reliance on the oral agreement. Equitable enforcement of part-performed parol leases generated substantial 19th-century case law. Researchers searching for cases on parol leases will encounter both law-side (Statute of Frauds defeats the lease) and equity-side (part performance saves it) lines of authority that appear to conflict but apply different analytical frameworks.
Historical dictionaries understate the nuance. Black's and Bouvier's define the parol lease cleanly as an oral rental agreement, but neither entry explains the Statute of Frauds threshold, the part-performance doctrine, or the conversion-to-periodic-tenancy outcome. A researcher relying solely on these definitions will miss the doctrinal complexity that governs whether a given parol lease mattered in litigation.
Terminology drift: older sources use "verbal lease" interchangeably with "parol lease." Rapalje & Lawrence's entry does exactly this. Both terms appear in indices and digests; search both when working through historical materials.

Historical Dictionary Support
All three source dictionaries agree on the core: a parol lease is an oral, unwritten lease of real estate. The entries are brief and convergent. Black's defines it as resting "in an oral agreement." Bouvier's adds the parties-and-estate framing but adds no doctrine. Rapalje & Lawrence supplies the most useful pointer, citing 29 Car. II, c. 3, § 2 — the Statute of Frauds — directly, which signals that the parol lease entry is a gateway to Statute of Frauds analysis rather than a self-contained concept.
What the historical dictionaries collectively omit is significant: none of the three addresses the part-performance exception, the conversion-to-tenancy outcome, or the duration threshold that separates enforceable from unenforceable parol leases. For these, researchers must move from the dictionary to the treatise literature — Kent's Commentaries, Taylor's Landlord and Tenant, or Tiffany on Landlord and Tenant — where the doctrine is developed fully.

Jurisdictional Note
American jurisdictions generally void parol leases for terms exceeding one year under their Statute of Frauds analogs, though a minority have set the threshold at three years (tracking the original English statute) or applied different rules to agricultural leases. Courts in equity have further varied outcomes through part-performance doctrine. English and American authorities cite the same originating statute but diverged in application over the 18th and 19th centuries; English and early American colonial-era materials should not be read as controlling on American jurisdictional outcomes without confirming local statutory adoption.
