Litigation finance underwriting borrows heavily from private equity and structured credit, but applies it to a binary, event-driven asset: a lawsuit either resolves favorably or it doesn't, and there is very little middle ground once a verdict or award is rendered. This is what makes the diligence process so intensive, funders describe it as frequently more thorough than a comparable M&A transaction, involving independent legal experts, outcome modeling, and direct interrogation of the claimant's own assumptions.
Capital deployment is staged, not lump-sum. Tranches are tied to the case clearing specific legal hurdles, surviving a motion to dismiss, completing key depositions, obtaining an expert report, so the funder's downside exposure at any given moment is smaller than the total committed capital. This staged structure is the primary risk control available once a decision to invest has been made.
At the portfolio level, sophisticated funders explicitly plan for a meaningful loss rate. Industry participants generally expect a typical commercial litigation finance fund to see something on the order of 20-40% of matters produce no recovery at all, offset by outsized returns on the winners, which is why portfolio construction, not single-case selection alone, is the real discipline of the business.
