Introduction

The law of insurable interest is set out in general terms in s 5 of the Marine Insurance Act 1906. The main requirement of insurable interest is, it would appear, to stamp out wagering contracts. It is also linked to the fact that a contract of marine insurance is a contract of indemnity; thus, an assured must first show that he has suffered a loss before he can put in a valid claim under the policy. A person can only suffer a loss if he has an interest in the subject matter insured; if he has no interest in the subject matter insured, he suffers no loss, and the contract of insurance is effectively a gamble or a wager, and, therefore, void under s 4 of the Act.

To have an insurable interest the assured must be ‘interested’ in a marine adventure. In the language of s 5(2), ‘…a person is interested in a marine adventure where he stands in any legal or equitable relationship to the adventure or to any insurable property at risk therein’. That this covers a wide range of persons is obvious: it includes the owner of the insurable property, a mortgagee and even an insurer. Apart from these three main classes, there are also other persons who might have an insurable interest in the subject matter insured, such as agents, executors, lien holders and trustees. The general principles applicable are the same in all cases.

The concept of insurable interest is broad; a person does not have to have a whole interest in the subject matter insured. The Act provides that limited forms of interest are also insurable, such as a partial interest (s 8), and a contingent or defeasible interest (s 7). The latter are interests the acquisition of which depends upon certain contingencies; for instance, a buyer may reject the goods on arrival if he is not satisfied with their condition, in which case the property in the goods reverts to the seller. The main problem with insurable interest concerns the time at which the interest must attach; as a general rule, the assured must, at the time of the loss, have an insurable interest in the subject matter insured. In contracts of international sale of goods, it is not always easy to ascertain at any given time whether the property has in fact passed from seller to buyer.

The law recognises certain exceptions to the general rule that the assured must have an insurable interest at the time of the loss. First, if the policy offers cover on a ‘lost or not lost’ basis, then the assured is, according to the proviso to s 6(1)1 permitted to recover under the policy even though the loss was sustained before the insurance was effected. This exception operates to protect an assured who might have purchased goods without knowing whether or not they have already been lost at sea. Secondly, an assignee of a policy can acquire an interest in the subject matter insured even though the policy was assigned to him only after the loss, provided, of course, that the assignor himself had, at the time of assignment, an interest to assign.2

Definitions of Insurable Interest

Section 5 of the Act defines ‘insurable interest’ as follows:

  1. Subject to the provisions of this Act, every person who is interested in a marine adventure.

  2. In particular, a person is interested in a marine adventure where he stands in any legal or equitable relation to the adventure or to any insurable property at risk therein, in consequence of which he may benefit by the safety or due arrival of insurable property, or may be prejudiced by its loss, or by damage thereto, or by the detention thereof, or may incur liability in respect thereof.

The most comprehensive of judicial pronouncements on the subject of insurable interest before the Act were delivered by Lord Eldon and Lawrence J, in Lucena v Craufurd, below. It would appear that the sentiments of Lord Eldon have been incorporated in the definition provided in s 5(2) of the Act, to the effect that the assured must stand in some relationship recognised by law to the subject matter insured.

Lucena v Craufurd (1806) 2 B&P (NR) 269, HL

The assured were the Commissioners of Admiralty, whose duty was, under statute, to take care of Dutch vessels and cargoes ‘which had been or might be thereafter detained in or brought into the ports of the United Kingdom’. Before the commission was issued, certain Dutch vessels and their cargoes had been seized by order of the British Government for the purpose of being brought to England. After the commission was issued, the Commissioners insured these ships and their cargoes. The ships were lost during their voyage to England. The Commissioners then sought to recover under the policy. The insurer's defence was that the Commissioners had no insurable interest in the ships at the time of loss.

The House of Lords upheld the insurer's defence on the basis that the Commissioners’ duty was to take care of the ships only after their arrival. Since the ships had not yet arrived in England at the time of loss, the Commissioners did not have an insurable interest. A panel of judges was summoned to advise the House on the issues raised; notably, Lawrence J offered his perception, sometimes referred to as ‘the moral certainty’ or the ‘factual expectancy’ test, of what constitutes ‘insurable interest’.

Chambre J: [p 298] …To constitute an interest, such as that which in the declaration is averred to be vested in the plaintiffs as Commissioners under the Act, I presume it must be necessary to show that the ships and goods at the time of the sailing, or at least before or at the times of the losses, had become the objects of the plaintiffs commission. If they were not the objects of their commission, I have no conception in what way they could have an interest in them as Commissioners.

Lawrence J: [p 300] …It is first to be considered what that interest is, the protection of which is the proper object of a policy of assurance. And this is to be collected from considering what is the nature of such contract.

[p 301] …that insurance is a contract by which the one party in consideration of a price paid to him adequate to the risk, becomes security to the other that he shall not suffer loss, damage, or prejudice by the happening of the perils specified to certain things which may be exposed to them.

[p 302] …That a man must somehow or other be interested in the preservation of the subject matter exposed to perils, follows from the nature of this contract, when not used as a mode of wager, but as applicable to the purposes for which it was originally introduced; but to confine it to the protection of the interest which arises out of property, is adding a restriction to the contract which does not arise out of its nature…A man is interested in a thing to whom advantage may arise or prejudice happen from the circumstances which may attend it… And whom it importeth, that its condition as to safety or other quality should continue: interest does not necessarily imply a right to the whole, or a part of a thing, nor necessarily and exclusively that which may be the subject of privation, but the having some relation to, or concern in the subject of insurance, which relation or concern by the happening of the perils insured against may be so affected as to produce a damage, detriment, or prejudice to the person insuring: and where a man is so circumstanced with respect to matters exposed to certain risks or dangers, as to have a moral certainty of advantage or benefit [emphasis added], but for those risks or dangers he may be said to be interested in the safety of the thing. To be interested in the preservation of a thing is to be so circumstanced with respect to it as to have benefit from its existence, prejudice from its destruction. The property of a thing and the interest devisable from it may be very different: of the first, the price is generally the measure, but by interest in a thing every benefit and advantage arising out of or depending on such thing, may be considered as being comprehended.

Lord Eldon: [p 318] …Accordingly, the power of the Commissioners is expressly limited to ships and goods that have actually come, or been brought into the ports of Great Britain…and it appears to me…that there is nothing in this Act of Parliament which touches the prerogative while the ships and cargoes were at sea…

[p 321] …Since the 19 Geo 2, it is clear that the insured must have an interest, whatever we understand by that term. In order to distinguish that intermediate thing between a strict right, or a right derived under a contract, and a mere expectation or hope, which has been termed an insurable interest, it has been said in many cases to be that which amount to a moral certainty. I have in vain endeavoured, however, to find a fit definition of that which is between a certainty and an expectation; nor am I able to point out what is an interest unless it be a right in the property, or a right derivable out of some contract about the property, which in either case may be lost upon some contingency affecting the possession or enjoyment of the party,

[p 323] …That expectation, though founded upon the highest probability, was not interest, and it was equally not interest, whatever might have been the chances in favour of the expectation.

[p 324] …If moral certainty be a ground of insurable interest, there are hundreds, perhaps thousands, who would be entitled to insure. First, the dock company, then the dock master, then the warehouse keeper, then the porter, then every other person who to a moral certainty would have anything to do with the property, and of course get something by it.

Notes

It can be seen from the above that Lawrence J had adopted a wide and most liberal approach, whilst Lord Eldon, a narrow and more legalistic approach to the term. It is pertinent to note that, recently, the ambit of the concept of ‘insurable interest’ had occasion to be looked at afresh in a trilogy of successive cases, the most notable of which is the Moonacre case, below...
