Begin with the governing doctrine
Property is a system of legally recognized relationships among people concerning resources, often described as a divisible bundle of rights to possess, use, exclude, transfer, and share. Real property is land and attached interests; personal property includes tangible movables and some intangible rights. Common-law first-possession doctrine asks what acts amount to capture or occupancy. Finder doctrine distinguishes lost, mislaid, abandoned, embedded, and treasure-like property while preserving superior claims of true owners, prior possessors, premises holders, and sovereign law.
Pin a context-specific law-of-finds example
The maritime excerpt states a possession rule for abandoned property at sea and expressly identifies disagreement between salvage and finds doctrines; it is not presented as the universal rule for land or ordinary found objects. Caption: Treasure Salvors, Inc. v. Unidentified Wrecked and Abandoned Sailing Vessel; court: United States Court of Appeals for the Fifth Circuit; decision date: 1978-03-13. Verbatim opinion excerpt: “The Atocha is indisputedly an abandoned vessel. Whether salvage law or the adjunct law of finds should be applied to property abandoned at sea is a matter of some dispute. Martin J. Norris, in his treatise on salvage law, states that under salvage law the abandonment of property at sea does not divest the owner of title. M. Norris, The Law of Salvage, § 150 (1958). Courts, however, have rejected the theory that title to such property can never be lost and have applied the law of finds. Wiggins v. 1100 Tons, More or Less, of Italian Marble, 186 F.Supp. 452, 456-57 (E.D.Va.1960). See Nippon Shosen Kaisha, K.K. v. United States, 238 F.Supp. 55, 59 (N.D.Cal.1964); Rickard v. Pringle, 293 F.Supp. 981, 984 (E.D.N.Y.1968). Under this theory, title to abandoned property vests in the person who reduces that property to his or her possession. In Rickard, for example, the court held that title to a propeller recovered from a vessel abandoned on the ocean floor for sixty years vested in “the first finder lawfully and fairly appropriating it and reducing it to possession, with the intention to become its owner.” Id. at 984, citing Wiggins, supra, sub nom. The Clythia.” Source: 569 F.2d 330; https://www.neochart.com/catalog/cases/f2d/volume_569/0330_01/index.html; data via neochart.com, snapshot 2026-08.
Pin a boundary of personal-property conversion
The excerpt identifies conversion as protecting possessory and ownership interests while showing that property classification can change in specialized human-material contexts. Caption: Moore v. Regents of the University of California; court: Supreme Court of California; decision date: 1990-07-09. Verbatim opinion excerpt: “Moore also attempts to characterize the invasion of his rights as a conversion—a tort that protects against interference with possessory and ownership interests in personal property. He theorizes that he continued to own his cells following their removal from his body, at least for the purpose of directing their use, and that he never consented to their use in potentially lucrative medical research. Thus, to complete Moore’s argument, defendants’ unauthorized use of his cells constitutes a conversion. As a result of the alleged conversion, Moore claims a proprietary interest in each of the products that any of the defendants might ever create from his cells or the patented cell line.” Source: 51 Cal. 3d 120; https://www.neochart.com/catalog/cases/cal-3d/volume_51/0120_01/index.html; data via neochart.com, snapshot 2026-08.
Pin the synthetic fact pattern
A synthetic packet separates capture of an unowned movable, discovery of an identified wallet in a shop, and research use of excised cells. No Texas statute is used as the acquisition rule.
Work the application
The capture event is tested under common-law acts of control and context, not pursuit alone. The wallet remains subject to the true owner's superior claim and requires lost-versus-mislaid and premises analysis. The biological-material record follows the case's specialized conversion boundary rather than ordinary finder doctrine. The model therefore preserves resource type, possession, intent, location, prior claims, and governing source.
Read the populated property record
The populated rows expose each claimed stick in the bundle, physical and legal control, resource classification, acquisition act, prior possessor, true owner, premises, abandonment, specialized regulation, and unresolved claim. The rendered record contains 14 populated rows.

Read the complete record
The complete record keeps sources, stated facts, and questions for review separate. Authority records: Verbatim snapshot sources. 51 Cal. 3d 120: Moore v. Regents of the University of California. 569 F.2d 330: Treasure Salvors, Inc. v. Unidentified Wrecked and Abandoned Sailing Vessel. Synthetic facts: Classroom facts only. Resource: Unowned movable is captured after pursuit and physical control. Found item: Wallet is discovered on a shop floor with owner identity inside. Biological material: Excised cells are used in research after medical removal. Classification: Land, movable object, information, body material, and intangible rights stay distinct. Application trace: Interests, events, rules, and unknowns. Bundle: Possess, use, exclude, transfer, divide, and destroy are separable and limited. First possession: Capture requires the jurisdiction's acts of control, not desire or pursuit alone. Finders: Lost, mislaid, abandoned, embedded, premises, and true-owner claims require classification. Context limit: Maritime finds and human biological materials do not state universal property rules.
Narrow summary
Property begins with relationships and classified interests; identify the resource, asserted stick, acquisition doctrine, prior claim, and governing context before declaring ownership.
