Definition:Broker's slip
📋 Broker's slip is a document prepared by an insurance broker that summarizes the key terms of a proposed insurance or reinsurance placement and is presented to underwriters for consideration and acceptance. Rooted in the traditions of the Lloyd's and London subscription markets, the slip serves as the primary vehicle through which brokers negotiate and secure coverage from multiple underwriters, each of whom initials or stamps the document to indicate the share of risk they are willing to accept. Though its form has evolved — from handwritten documents carried around the Lloyd's underwriting room to electronic equivalents processed through platforms like PPL — the broker's slip remains conceptually central to how subscription-market business is transacted.
⚙️ The slip typically contains a concise presentation of the insured, the nature of the risk, the proposed coverage terms and exclusions, the premium rate, deductible levels, policy period, and any relevant warranties or subjectivities. The lead underwriter reviews the slip first, negotiating terms with the broker before writing a line — the percentage of the risk they will take. Once the lead has committed, the broker approaches following underwriters to fill the remaining capacity, each signing on at the terms the lead has established, sometimes with minor modifications. In the London market, the Market Reform Contract and associated standards have formalized slip content requirements, while electronic placing platforms have introduced structured data fields that improve consistency and reduce processing friction. Outside London, subscription-market mechanisms in Bermuda, Singapore, and other hubs follow analogous processes, though the documentation conventions may differ.
💡 The broker's slip occupies a unique legal and commercial position: while it is not always the final policy document, courts in various jurisdictions — particularly under English law — have held that a signed slip can constitute a binding contract of insurance when its terms are sufficiently definite. This gives the slip an importance that transcends its role as a mere summary; it is the moment at which risk attaches and commercial commitments crystallize. For brokers, crafting a clear and accurate slip is an essential professional skill — ambiguities or omissions at the slip stage can propagate into coverage disputes, claims difficulties, and errors-and-omissions exposure. The ongoing digitization of the slip process through initiatives like the Lloyd's Blueprint Two modernization program aims to reduce cycle times and improve data quality, but the document's fundamental function — as the concise, negotiable expression of a proposed risk transfer — endures.
