Definition
Support, in law, encompasses several distinct legal obligations and property rights, each arising in different contexts:
1. FAMILY SUPPORT (DOMESTIC RELATIONS). The legal obligation of one person to provide financial maintenance for another. Encompasses child support — the duty of a parent (or both parents) to provide financially for a minor child — and spousal support (alimony or maintenance), the obligation of one spouse or former spouse to provide for the other following separation or divorce. The duty of support may also extend to other dependents, such as elderly parents in some jurisdictions.
2. SUPPORT AS A PROPERTY RIGHT (REAL PROPERTY). An easement or right entitling a landowner to have their structure or land physically upheld by adjacent or underlying property. Divided into two recognized subtypes: lateral support (the right of land to be held up by the soil of neighboring parcels) and subjacent support (the right of surface land to be upheld by the subsurface, relevant when mineral rights are severed). A separate contractual or prescriptive easement allows a building owner to rest joists or timbers against an adjoining owner's wall.
3. SUPPORT AS CONTRACTUAL OR EQUITABLE OBLIGATION. A promise or undertaking to furnish sustenance, housing, or maintenance to another person. May arise by contract (as in a support agreement) or by operation of law. Historically significant in cases involving consideration for property transfers, where a grantor conveyed land in exchange for a promise of lifetime support.

Common Language
Modern common usage (Wiktionary): To help keep from falling; to back or favor a cause; to provide sustenance or maintenance; to help financially; to provide evidence for.
Historical common usage (Webster's 1913): To bear by being under; to keep from falling; to uphold or sustain in a literal or physical sense; to endure without being overcome.
The gap between common and legal usage here is one of precision, not reversal. Ordinary English uses "support" loosely across physical, financial, and emotional registers. Law sharpens the term into enforceable obligations (family support), protected property rights (lateral and subjacent support), and contractual duties. A researcher encountering "support" in a legal document must immediately identify which register is operative — the word carries entirely different doctrinal freight depending on context.

Common Confusion
Support vs. Maintenance vs. Alimony: These terms are frequently used interchangeably in both statutes and legal writing, but courts and legislatures have not been consistent. "Alimony" is the traditional term for post-divorce spousal payments; "maintenance" is preferred in the Uniform Marriage and Divorce Act and many modern state codes; "support" is the broadest term, sometimes encompassing both spousal and child obligations together. In older cases and historical sources, "maintenance" also appears in an entirely different sense — wrongful support of another's litigation (see MAINTENANCE, champertous). Researchers must be alert to which meaning is operative before cross-referencing.
Lateral Support vs. Subjacent Support: Lateral support concerns the horizontal holding of land by adjacent parcels at the same level. Subjacent support concerns the vertical holding of surface land by what lies beneath it. The distinction matters when surface and subsurface ownership are split — a common situation in mining jurisdictions — and when identifying which party bears liability for subsidence.

Recognized Forms
/SUBTYPES
FAMILY SUPPORT
- Child Support: Periodic financial payments for the care, maintenance, and education of minor children, typically ordered by a court incident to divorce, paternity adjudication, or separate support proceedings.
- Spousal Support / Alimony / Maintenance: Payments from one spouse or former spouse to the other, either temporary (pendente lite) or permanent, rehabilitative, or reimbursement-based.
- Retroactive Support: Support awarded for a period prior to the filing of a petition or court order.
- Palimony: Support obligations asserted between unmarried cohabiting partners, grounded in contract or equitable theory rather than family law status.
PROPERTY SUPPORT
- Lateral Support: The right of land to be upheld by adjoining land at the same surface level.
- Subjacent Support: The right of surface land to be upheld by the subsurface strata beneath it.
- Structural Support Easement: An easement, by contract or prescription, allowing one building owner to rest structural members against or upon a neighbor's wall.

Why It Matters in Research
The word "support" is a false friend in legal research: its apparent simplicity conceals at least three distinct doctrinal regimes with separate bodies of case law, statutory frameworks, and historical development.
In the family law corpus, the most important navigational warning is jurisdictional terminology drift. Statutes enacted from the mid-twentieth century onward frequently replaced "alimony" with "maintenance" or "spousal support," and consolidated child and spousal obligations under umbrella "family support" provisions. A researcher working across time periods or jurisdictions must track which word a given court or legislature is using and whether it maps to the doctrinal category they need. Retroactive child support and paternity as a prerequisite to support are areas where historical sources are silent or misleading — pre-twentieth-century authorities largely assumed paternity adjudication within marriage and did not develop doctrine for the modern unmarried-parent context.
In the property law corpus, lateral and subjacent support were treated as absolute rights at common law — a landowner was strictly liable for withdrawal of natural support, regardless of negligence. This strict liability rule has been modified in many jurisdictions for improved land (structures), where negligence principles may govern. Researchers using Bouvier or older treatises will encounter the absolute rule stated without qualification; modern sources reflect a more nuanced picture.
The contractual support obligation — land conveyed in exchange for lifetime care — generates a specialized body of deed construction cases and raises issues of consideration, fraud, and constructive trust. These cases sit awkwardly across property, contracts, and family law research and may not surface cleanly in any single subject search.
Anderson's truncated example (the letter promising to pay for "S. and family's support") points to an important line of cases on the scope of open-ended support promises and the limits of promissory liability — relevant to both contract and domestic relations research.

Historical Dictionary Support
Bouvier is the most substantive of the three sources on this term. His treatment centers on the property right of support — specifically the easement allowing a building owner to rest timbers on a neighbor's wall, and the right to lateral and subjacent support of land. His citation to Kent and Washburn grounds the doctrine in the leading nineteenth-century American property treatises. Bouvier does not develop family support doctrine at comparable length, reflecting the era's tendency to treat domestic obligations as matters of status rather than enforceable legal rights subject to dictionary treatment.
Rapalje & Lawrence's fragment is contextually unhelpful — the text is clearly mid-entry, referring to "the right of support to l—" with the remainder cut off — but the surrounding context (the supplicavit writ, articles of the peace) suggests the entry dealt with property support in the context of adjoining structures, consistent with Bouvier.
Anderson offers a brief but instructive example: a letter promising to pay for another's "support" held not to create recoverable liability in the manner the promisee claimed. This captures the historical judicial skepticism toward open-ended, indefinite support promises and the importance of construing the scope of such obligations. Anderson's reference to "sustenance" and "maintenance" as near-synonyms reflects nineteenth-century usage that did not sharply distinguish these terms.
All three historical sources are silent on child support as a statutory enforcement mechanism, which is a modern development. They are also silent on spousal support as a post-divorce right with discretionary judicial modification — a doctrine that developed substantially through twentieth-century case law and the Uniform Acts. Researchers relying on these sources alone will find the property law dimension reasonably covered but the domestic relations dimension substantially underdeveloped.

Jurisdictional Note
Family support law is almost entirely state-governed, and terminology, calculation methods, and enforcement mechanisms vary substantially across jurisdictions. Federal law (Title IV-D of the Social Security Act) has imposed significant uniformity in child support enforcement and guideline requirements, but spousal support remains highly non-uniform. In community property states, the conceptual framework for support obligations at divorce differs from common law states. For property support rights, most American jurisdictions follow the common law absolute right for natural lateral support, with variation for improved land.
