Lloyd’s v Harper (1880) 16 Ch D 290

A father gave a guarantee to the Lloyd's committee concerning the underwriting engagements of his son on admission as a member. Lloyd's later became incorporated. The father died, and notice of his death was given, but the son continued underwriting before eventually becoming bankrupt. Lloyd's sought to enforce the guarantee against the father's estate for covered liabilities. The dispute concerned whether the undertaking had ended on death and whether substantial recovery was possible when the immediate promisee had not itself suffered the losses of the persons protected by the arrangement.

Did the guarantee continue after the father's death, and could Lloyd's enforce it for the losses of the persons beneficially protected by the undertaking?

The Court of Appeal held that the guarantee continued after the guarantor's death on its proper construction. It had supported the son's admission to Lloyd's and was not treated as a series of fresh revocable offers ending automatically when the father died. The father's estate remained answerable for the liabilities covered by the undertaking. The committee could recover substantial sums despite not itself suffering the underwriters' losses, because the arrangement was treated as held for the persons beneficially interested. The decision therefore involved both construction of a continuing guarantee and enforcement through a trust of contractual rights. It does not establish that every guarantee survives death regardless of its wording and circumstances.

The effect of a guarantor's death depends on the guarantee's construction and the transaction supporting it. A contracting trustee may enforce a promise for beneficiaries and recover the relevant loss; that mechanism is distinct from an unrestricted rule allowing every promisee to recover any third party's loss.

Lloyd's v Harper connects guarantees with the historical trust-based response to privity difficulties. It is useful where the promisee receives an undertaking for the protection of an identifiable class. The trust finding matters and should not disappear behind broad language about beneficiaries. Modern problems may also raise the Contracts (Rights of Third Parties) Act 1999. Separately, whether an estate remains liable under a guarantee requires construction of the particular undertaking rather than a blanket rule triggered simply by the label guarantee.
