Data on the Enforcement of Forum Selection Clauses

The United States legal system is immensely complex. There are state courts and federal courts, state statutes and federal statutes, state common law and federal common law. When I imagine a foreign lawyer trying to explain this system to a foreign client, my heart fills with pity.

This feeling of pity is compounded when I imagine this same lawyer trying to advise her client as to whether a forum selection clause will be enforced by a court in the United States. The law on this subject is complicated. It is, moreover, not easy to determine how it is applied in practice. Are there differences in clause enforcement rates across the states? Across federal circuits? Do state courts enforce these clauses at the same rate as federal courts? Until recently, there was no data that would allow a foreign lawyer – or a U.S. lawyer, for that matter – to answer any of these questions.

Over the past several years, I have authored or co-authored several empirical articles that seek to answer the questions posed above. This post provides a summary of the data gathered for these articles. All of the cases referenced involve outbound forum selection clauses, i.e. clauses that select a jurisdiction other than the one where the suit was filed. Readers interested in the data collection process, the caveats to which the data is subject, or other methodological issues should consult the articles and their appendices. This post first describes state court practice. It then describes federal court practice. It concludes with a brief discussion comparing the two.

State Courts

Most state courts have held that forum selection clauses are presumptively enforceable. These courts will not, however, enforce a clause when it is unreasonable or contrary to public policy. A clause may be deemed unreasonable when enforcement would result in duplicative litigation, when the plaintiff cannot obtain relief in the chosen forum, when the plaintiff was never provided with notice of the clause, when the chosen forum lacks any relationship to the parties, or when litigation in the chosen forum would be so gravely difficult and inconvenient that the plaintiff would be deprived of her day in court. A clause is contrary to public policy when a statute or a judicial decision declares that enforcement is inconsistent with the policy of the state.

The chart below lists the enforcement rate in state courts with at least ten judicial decisions between 2010 and 2020. These rates were calculated by dividing (1) the total number of cases where a clause was enforced by (2) the total number of cases where the court considered the issue of enforceability.

 

State

 

Enforcement Rate

2010-2020

California 78%
Connecticut 88%
Delaware 100%
Florida 100%
Georgia 54%
Illinois 83%
All States 79%
Louisiana 70%
Michigan 82%
New Jersey 64%
New York 76%
Ohio 73%

Between 2010 and 2020, state courts enforced forum selection clauses in 79% of cases. Although there are significant differences in enforcement rates across the country, forum selection clauses are given effect by state courts in the vast majority of cases.

Federal Courts

Like state courts, federal courts take the position that forum selection clauses are presumptively enforceable. Like state courts, federal courts will not enforce these clauses when they are unreasonable or contrary to public policy. Unlike state courts, federal courts do not apply state law to decide the issue of enforceability. They apply federal law. This means that the federal courts are free to adopt their own view of whether a clause is unreasonable or contrary to public policy without considering prior state court decisions.

In theory, the fact that the federal courts apply federal law to this question should produce uniform results across the nation. In fact, there are notable variations in enforcement rates across federal district courts sitting in different circuits, as shown in the chart below.

 

 

Circuit

 

Enforcement Rate

All Federal Cases

2014-2020

Eleventh Circuit 95%
Third Circuit 92%
Second Circuit 91%
Sixth Circuit 91%
Fifth Circuit 90%
Fourth Circuit 90%
All Circuits 88%
Seventh Circuit 87%
First Circuit 84%
Eighth Circuit 85%
Tenth Circuit 83%
Ninth Circuit 81%

The federal district courts sitting in the Eleventh Circuit, which includes Florida, have the highest enforcement rate. The federal district courts sitting in the Ninth Circuit, which includes California, have the lowest enforcement rate. On the whole, a plaintiff arguing that a forum selection clause is unenforceable would rather be in federal court in California than in Florida. Even in California, however, these clauses are still enforced by federal courts in the overwhelming majority of cases.

Comparing State and Federal Courts

Federal courts sitting in diversity enforce forum selection clauses at a rate that is equal to or greater than the rate of geographically proximate state courts in every federal circuit. In the Fourth and Eighth Circuits, the enforcement gap is particularly large, as shown in the chart below.

Fifth Circuit 90% 90% 0%
Seventh Circuit 85% 85% 0%

These data suggest that a defendant seeking to enforce a forum selection clause should try to remove the case to federal court. These courts are, on average, more likely to enforce a clause than their state counterparts. The data further suggest that plaintiffs seeking to invalidate a forum selection clause should strive to keep the case in state court. These courts are, on average, less likely to enforce a clause than their federal counterparts. The incentives for forum shopping as between state and federal court when it comes to forum selection clauses raise serious concerns under the U.S. Supreme Court’s decision in Erie Railroad Company v. Tompkins, as discussed at greater length here,

There are two main reasons why the enforcement rate is higher in federal court. First, some federal courts applying federal law refuse to give effect to state statutes that invalidate forum selection clauses. When these invalidating statutes are applied by state courts and ignored by federal courts, the result is a sizable enforcement gap. The Supreme Court recently denied cert in a case that would have resolved the question of whether federal courts should give effect to state statutes that invalidate forum selection clauses.

Second, federal courts applying federal law are less willing than state courts applying state law to conclude that a clause is unreasonable. Over many cases decided over many years, state court judges have shown themselves to be more sympathetic to plaintiffs seeking to avoid forum selection clauses. Federal courts, by comparison, have enforced clauses in a number of instances where state courts probably would have refused on unreasonableness grounds.

Conclusion

The law of forum selection clauses in the United States is sprawling and complicated. Until recently, there were no empirical studies addressing how the courts applied this law in practice. The information presented above is the product of hundreds of hours of work reading thousands of state and federal cases in an attempt to identify patterns and trends.
