How to Model Litigation as a Game
A practical guide to treating a lawsuit as a strategic game with players, moves, and payoffs instead of a linear story.
Litigation looks like a story from the inside: a sequence of filings, hearings, and conversations that build toward one climax. Modeled as a game, that same matter becomes a set of players, each with a defined set of moves available at defined decision points, and a payoff attached to every combination of choices. Motions, discovery requests, settlement offers, and even the timing of a filing are all moves. Treating the case this way does not strip out the human element; it forces the human judgment that was already happening informally into a structure you can examine, question, and test against alternative assumptions before committing to a strategy.
This is not an attempt to reduce a court case to a board game or to claim a formula can replace legal judgment. Real litigation is a game of imperfect information: each side knows things the other does not, bluffs are possible, and even the rules themselves can be contested. What a game-theoretic model adds is a disciplined way to reason about strategy under that uncertainty, surfacing where an equilibrium strategy exists and how exploitable a given approach is to a well-prepared opponent. Juricratic runs this as a seeded simulation across the dials you set, producing a distribution of strategic outcomes rather than a single predicted result.
Define the players and their real objectives
Start with more than plaintiff and defendant. Inside each side sits a client with a financial or personal stake and counsel who may face different incentives, including hourly billing, contingency structure, reputational concerns, or caseload pressure. These agency costs matter because a lawyer optimizing for the client's outcome and a lawyer optimizing for their own fee structure can choose different moves at the same decision point. List every party and sub-party whose incentives could plausibly diverge from the outcome you assume they are pursuing, and note where those incentives create friction the model needs to account for.
Map the actual strategy space at each decision point
A game only means something once you specify what moves are actually available to each player at each point in time. In litigation, that includes filing or withholding a motion, the scope and timing of discovery requests, whether and when to make a settlement offer, and how aggressively to prepare for trial versus preserve resources. Keep the list grounded in what is procedurally and practically available in this matter and this jurisdiction, not a theoretical menu of every move a case could ever have. An overbuilt strategy space adds noise; a strategy space that leaves out a real option produces a model blind to your opponent's best move.
Assign payoffs for every combination of moves
Once the moves are mapped, build a payoff matrix describing what each side nets under every combination of choices, including litigation costs, time, and any asymmetry in exposure. Payoffs are rarely symmetric: a defendant's cost of prolonged discovery is not the same as a plaintiff's, and a client's payoff often differs from counsel's if fee arrangements are not aligned. Express payoffs in the same unit, typically net expected dollar value, so the matrix can actually be compared and solved rather than argued about qualitatively.
Model what each side does and does not know
Chess is a perfect-information game; litigation is not. Each party holds private information about the strength of its own evidence, its true settlement floor, and its actual appetite for trial, and each has an incentive to signal or conceal that information strategically. Model these gaps explicitly rather than assuming both sides are working from the same facts. A settlement offer that looks irrational under perfect information can be a perfectly rational move once you account for what the other side believes you do not know, or does not yet know itself.
Solve for equilibrium and check how exploitable it is
With players, moves, and payoffs defined, solve for the strategy combination where neither side can unilaterally improve its outcome by changing its own move, holding the other's strategy fixed. That equilibrium is a useful anchor, but it is not the end of the analysis: also measure the exploitability gap, meaning how much a well-informed opponent could gain by deviating from the equilibrium and playing a best response instead. A strategy that looks optimal in equilibrium but carries a wide exploitability gap is fragile against a sophisticated opposing counsel who spots the same model you did.
Re-run the model as assumptions change
A litigation game is not solved once and filed away; the payoffs and probabilities behind it shift with every ruling, deposition, and new document. Re-run the model whenever a material assumption changes, and treat the recommended strategy as conditional on the inputs you fed it rather than a fixed conclusion. Compare the new equilibrium to the old one to see whether a ruling or piece of evidence actually changed the optimal move, or only changed the confidence behind a move you were already making.
- What is the difference between modeling litigation as a game and building a decision tree?
- A decision tree models one side's choices against chance events, folding backward to a single expected value. A game-theoretic model adds a second strategic actor whose choices respond to yours, so the right move depends on what a rational opponent is likely to do in response, not just on a fixed set of probabilities. Game models suit negotiation and settlement dynamics; decision trees are often simpler for procedural or evidentiary sequences.
- Can game theory tell me whether my opponent will settle?
- No. It can tell you the range of strategies that are rational for an opponent with a given set of incentives and information, and how exploitable your own strategy is if those assumptions are wrong. It does not predict a specific person's decision, and treating its output as a forecast rather than a structured way to stress-test strategy defeats the purpose of building the model in the first place.
- What makes litigation an imperfect-information game rather than a perfect-information one?
- In a perfect-information game like chess, both players see the entire board at every move. In litigation, each side has private knowledge of its own evidence, witness credibility, budget constraints, and true settlement floor that the other side cannot directly observe. Strategies have to account for beliefs about hidden information, including the possibility of bluffing or strategic delay, rather than complete knowledge of the state of play.
