Definition:Insurance slip
📝 Insurance slip is the document used in subscription insurance markets — most notably at Lloyd's of London — to present the key terms of a proposed risk and to record each underwriter's agreement to accept a share of that risk. Historically a physical sheet of paper carried by a broker around the underwriting room, the slip contains essential information such as the insured's name, the type of coverage, policy period, limits, deductible, premium rate, and any notable conditions or exclusions. Each participating underwriter "scratches" the slip — adding their initials and the percentage line they are willing to write — until the risk is fully subscribed.
🔄 The subscription process begins when the broker prepares the slip based on the risk information gathered from the client and presents it to a lead underwriter who sets the pricing and terms. Once the lead signs on, the broker approaches following underwriters who may accept the lead's terms or negotiate modifications. In the Lloyd's market, the slip has been progressively digitized through platforms like PPL and the broader Blueprint Two modernization initiative, which aim to replace paper-based workflows with electronic placement. Even in its digital form, the slip retains its core function: it acts as the provisional binding record before the formal policy wording is issued.
📌 Despite appearing to be a simple summary document, the slip carries significant legal and commercial weight. In many subscription markets, the slip constitutes evidence of a binding contract between the insured and the participating underwriters — meaning disputes can turn on the precise language it contains. This is why both brokers and underwriters invest considerable care in drafting slip terms clearly and ensuring that what appears on the slip accurately reflects the negotiated deal. For insurtech firms building digital placement solutions, replicating the flexibility and legal standing of the traditional slip while adding structured data, audit trails, and straight-through processing to downstream systems such as policy administration and bordereaux reporting remains a central design challenge.
