Definition
A clause inserted in a marine or other insurance policy declaring that the policy is valid regardless of whether the insured has any insurable interest in the subject matter. The phrase operates as a waiver of the insurable interest requirement — the insurer agrees to pay the stipulated sum upon the occurrence of the covered event whether or not the insured stands to suffer any actual loss from it.
The practical effect is to transform the contract from a contract of indemnity into a wager: the insured is betting, in essence, that the ship sinks, the cargo is lost, or the life ends, and the insurer is betting the opposite. Because the insured need not own, hold, or be financially exposed to the subject matter, no actual loss is required for recovery, and no principle of indemnity applies.
Such policies are also called wager policies or P.P.I. policies (policy proof of interest), the latter being the form most common in historical marine practice.
Common Confusion
INTEREST OR NO INTEREST vs. INSURABLE INTEREST: These are conceptually opposite positions. A policy requiring insurable interest conditions enforceability on the insured's demonstrated financial stake in the subject matter. A policy written "interest or no interest" expressly abandons that condition. Researchers encountering either phrase in historical sources should not treat them as synonyms or assume the same legal treatment applied to both.
INTEREST OR NO INTEREST vs. P.P.I.: In historical marine insurance practice, "P.P.I." (policy proof of interest) and "interest or no interest" clauses served the same function and were often used interchangeably. Both dispensed with the requirement that the insured prove an insurable interest. The distinction is terminological, not substantive.
Why It Matters in Research
This term belongs almost entirely to historical legal research. The clause was rendered void in England by the Marine Insurance Act of 1745 (19 Geo. II, c. 37) and has had no legal force in English or most American law since. Researchers working with pre-1745 English marine insurance materials, or with cases litigating the enforceability of such policies after the statute, will encounter this phrase frequently.
The trap in historical sources is that the clause continued to appear in policies long after the 1745 statute made it void — particularly in Lloyd's market practice — because both parties understood it as a commercial convention rather than a legally operative term. Courts therefore had to repeatedly address whether a policy containing the clause was entirely void or merely unenforceable as to the wagering element. Researchers should not assume that the presence of the clause in a post-1745 policy means the policy was treated as valid or that litigation over it was straightforward.
In American sources, the treatment was less uniform. Several states addressed wager policies through their own insurance statutes or common law development, and the enforceability of "interest or no interest" clauses varied by jurisdiction and era. Historical American insurance treatises and state-level insurance commission reports are often more informative than the general dictionaries on this point.
The term also surfaces in admiralty and maritime law research, where the line between insurance contracts and gambling contracts was contested in both the courts and Parliament throughout the eighteenth century. Understanding the phrase requires familiarity with the broader doctrine of insurable interest, which developed substantially in response to the abuses that wager policies represented.
Historical Dictionary Support
The four historical dictionaries in the Law Mind corpus are in close agreement on the core meaning and legal consequence of this term. All four identify the "interest or no interest" clause as the defining feature of a wager policy, and all treat such policies as legally problematic or void.
Burrill's provides the most precise historical grounding, citing the 1745 statute by chapter and connecting the clause to the specific marine insurance context where it arose — covering goods aboard ship when the insured had no actual property on board. Burrill also cites Blackstone's Commentaries (2 Bl. Com. 460), which underscores how settled the condemnation of such policies was in English legal culture by the time the major dictionaries were written.
Bouvier goes further than the others in noting that the clause renders a wager policy "bad generally, from the policy of the law" — not merely void by statute — suggesting that even in jurisdictions without a direct statutory counterpart to 19 Geo. II, courts might find such policies unenforceable on public policy grounds. This is a useful signal for American research in states that did not early adopt specific wager policy statutes.
Black's is the most concise but captures the essential modern (or late-nineteenth-century) understanding: the clause waives insurable interest and produces a wager policy. Rapalje & Lawrence is characteristically brief, simply confirming the wager policy consequence and flagging the void status.
None of the historical dictionaries discuss the P.P.I. variant at length, and none engage with the question of how courts treated policies bearing the clause in the decades after the 1745 statute when the clause persisted as market practice. Researchers needing that analysis must look beyond the dictionary shelf to insurance law treatises, particularly Arnould on Marine Insurance, which addresses the post-statute litigation in depth.
Jurisdictional Note
In England, wager policies including those written "interest or no interest" were prohibited by the Marine Insurance Act of 1745 and later consolidated under the Marine Insurance Act 1906. In the United States, treatment varied by state; many states enacted analogous prohibitions through insurance codes, but the timing and scope differed. Researchers should not assume uniform American condemnation without checking the relevant state's statutory history.
Encyclopedia Cross-Reference
No Law Mind Encyclopedia entry directly addresses wager policies or the interest or no interest clause. The matching entries returned — covering future interests in property law, tax overpayment interest, and the classification of future interests in estates — address "interest" in entirely different legal senses and are not relevant to this term.
