Who Pays the Lawyers? A Rule That Decides Who Can Sue

Two main rules operate and the difference is fundamental. Under the loser pays approach, used across most of Europe and the Commonwealth, the unsuccessful party is ordinarily ordered to pay a substantial share of the successful party's legal costs as well as their own, subject to the court's discretion and to assessment of what was reasonable. Under the each side bears its own costs approach, used in the United States for most litigation, neither party recovers from the other regardless of outcome, with exceptions written into particular statutes. Both are defensible and both produce systematic effects on behaviour that the other does not, which is why the choice is a genuine policy question rather than a technical detail.

The incentives run in opposite directions and are well documented:

• •Loser pays discourages weak claims, since bringing one risks paying both sides
• •It equally discourages meritorious claims by anybody who cannot absorb that risk
• •It compensates a successful party rather than leaving them out of pocket for being right
• •Each side bearing its own costs lowers the barrier to bringing a case at all
• •It also lowers the cost of bringing a weak one and raises the value of a nuisance settlement
• •It makes defending an unmeritorious claim expensive even when the defence succeeds

Systems using the loser pays rule have developed mechanisms to stop it excluding people. Legal aid funds cases for those who qualify, and its contraction in several countries has been the single largest change in access to justice in decades. Insurance can be bought before or after a dispute arises, covering the exposure to the other side's costs. Conditional and contingency fee arrangements let a lawyer share the risk in exchange for a share of the outcome. Protective costs orders cap exposure in cases raising public interest issues. Fixed cost regimes make the exposure predictable in defined categories. Formal settlement offers shift the costs risk onto a party who refuses a reasonable offer and then does no better at trial, which is a powerful pressure to settle.

The size of the bills is what makes the rule matter, and the drivers are structural rather than a matter of rates. Disclosure of documents is the largest single cost in substantial cases, since every relevant document must be identified, reviewed and listed, and electronic records have multiplied the volume enormously. Expert evidence requires paying specialists on both sides and frequently a third to assist the court. Procedural steps each generate work, and an opponent can increase costs deliberately by contesting everything. Court fees have risen sharply in several jurisdictions. And the adversarial structure duplicates effort by design, since both sides investigate the same facts separately. Reforms have targeted each of these, with mixed results, and proportionality has become the organising principle in several systems.

The practical effect is that the costs rule decides which disputes reach a court at all, and it does so differently for different parties. An individual against a large organisation faces asymmetric risk, since the organisation can absorb an adverse order and the individual cannot, which deters claims regardless of merit. Group litigation changes that arithmetic by spreading the exposure. Organisations aware of the asymmetry can use it, and the deployment of costs risk to discourage claims and criticism has attracted specific legislation in several jurisdictions. Whichever rule applies, the dominant reality is that litigation costs enough that the great majority of disputes settle, and the settlement figure reflects each side's costs exposure as much as the merits.

Under one rule the loser pays a share of the winner's costs and under the other each side pays its own, and the choice decides who can afford to sue. Loser pays deters weak claims and equally deters meritorious ones from anybody who cannot absorb the risk. Legal aid, insurance, conditional fees and costs caps exist to manage that, and most disputes settle on the arithmetic rather than the merits.
