Definition
A clause inserted in leases, rental agreements, and contracts for the sale or use of property that exempts a party — typically a tenant or buyer in possession — from liability for the ordinary deterioration of property that results from normal, expected use over time. When a lease provides that premises must be returned in good condition "natural and reasonable wear and tear excepted," the tenant is not responsible for the gradual decline in condition that any reasonable occupant would cause simply by living or working in the space.
Wear and tear in this sense means physical deterioration attributable to time, ordinary friction, and reasonable use — as distinguished from damage caused by accident, neglect, misuse, or intentional act. A carpet worn thin by years of foot traffic is wear and tear. A carpet burned by a dropped iron is damage beyond it.
The phrase operates as a carve-out or safe harbor within an otherwise broad obligation to maintain or restore property. It allocates the cost of inevitable decline to the landlord or seller rather than the party in possession, recognizing that some deterioration is an inescapable incident of use.

Common Language
Modern common usage (Wiktionary): "Wear and tear" — damage or deterioration resulting from ordinary use.
Historical common usage (Webster's 1913): "Wear" — the act of wearing, or the state of being worn; diminution by friction; use.
The everyday phrase "wear and tear" captures roughly the same idea as the legal term, but the legal formulation adds important precision. Courts have been required to distinguish "natural and reasonable" wear and tear from damage that, while not malicious, exceeds what ordinary use produces. The modifiers matter: deterioration must be both natural (resulting from the inherent properties of materials aging) and reasonable (consistent with the use for which the property was let). A common-language understanding of the phrase tends to be more forgiving than courts applying the legal standard in landlord-tenant disputes.

Common Confusion
The phrase is frequently confused with, or used interchangeably with, "damage," but the two occupy opposite sides of a legal line. Damage implies harm beyond the ordinary — something a reasonable tenant could have avoided. Wear and tear implies the opposite — harm no reasonable tenant could have prevented simply by occupying the premises. The confusion generates significant litigation at lease termination over security deposit deductions. Landlords sometimes characterize ordinary aging as damage; tenants sometimes characterize preventable harm as wear and tear. Neither characterization controls; courts apply an objective standard of what a reasonable tenant in that type of property would ordinarily cause.

Why It Matters in Research
Researchers working with historical leases, tenancy agreements, or property sale contracts will encounter this phrase as a standard clause whose precise scope was rarely spelled out in the document itself and was left to judicial interpretation. The practical content of "natural and reasonable" shifted over time as courts in different jurisdictions addressed specific fact patterns — painted walls, worn flooring, faded fixtures — producing a body of case law that defines the clause's edges more than any statutory text does.
Several research traps arise:
First, the clause appears in multiple contractual contexts — residential leases, commercial leases, agricultural tenancies, hire-purchase agreements, and contracts for the sale of goods or chattels — and what counts as "reasonable" wear varies by context. A residential standard does not map cleanly onto a commercial one.
Second, the burden of proof allocation differs by jurisdiction and era. In some authorities, the landlord bears the burden of proving damage beyond ordinary wear; in others, the tenant bears the burden of proving that deterioration fell within the exception. Historical sources may assume one allocation without stating it.
Third, the clause interacts with repair covenants and condition-at-commencement provisions. Researchers should trace how courts in the relevant jurisdiction treated the interplay between a tenant's covenant to repair and the wear-and-tear exception — in some lines of authority, the exception qualifies the repair covenant; in others, it operates independently.
Fourth, the Rapalje & Lawrence citation (Spenc. (N.J.) 544) points to New Jersey Chancery practice, suggesting early American usage was grounded in equity jurisdiction over property disputes. Researchers in equity or chancery records should be alert to the clause appearing in that context as well as in common-law lease litigation.

Historical Dictionary Support
Rapalje & Lawrence define the term economically, citing a single New Jersey chancery authority without elaboration: the entry reads simply "TEAR EXCEPTED, (in an agreement for the sale of property). Spenc. (N. J.) 544." The truncated form of the entry — the full phrase being "natural and reasonable wear and tear excepted" — reflects the dictionary's indexing practice rather than any narrowing of the concept. The citation to Spencer's New Jersey Equity Reports locates the term in mid-nineteenth-century American equity jurisprudence.
What historical dictionaries of this period largely omit is any systematic treatment of the substantive standard — they register the clause's existence and its transactional context without unpacking what "natural and reasonable" requires. Researchers relying solely on dictionary sources for the legal content of the standard will need to move to treatises on landlord-tenant law and the case law itself. English authorities (particularly on agricultural and urban residential tenancies) supply a richer analytical foundation than most nineteenth-century American dictionary entries.

Jurisdictional Note
American jurisdictions vary on whether the wear-and-tear exception is implied by law even when not stated, and on the landlord's obligations regarding security deposit deductions tied to the distinction. Many states have codified the concept in residential landlord-tenant statutes. English common law, from which the clause descends, developed the standard primarily through agricultural tenancy cases, and researchers should be cautious about direct transplantation of English authority into American commercial or residential lease contexts.
