In England and Wales, a contract may be enforced by use of a claim, or in urgent cases by applying for an interim injunction to prevent a breach. Likewise, in the United States, an aggrieved party may apply for injunctive relief to prevent a threatened breach of contract, where such breach would result in irreparable harm that could not be adequately remedied by money damages.

Arbitration.

If the contract contains a valid arbitration clause then, prior to filing a lawsuit, the aggrieved party must submit an arbitration claim in accordance with the procedures set forth in the clause. Many contracts provide that all disputes arising thereunder will be resolved by arbitration, rather than litigated in courts.

Arbitration judgments may generally be enforced in the same manner as ordinary court judgments and are recognized and enforceable internationally under the New York Convention, which has 156 parties. However, in New York Convention states, arbitral decisions are generally immune unless there is a showing that the arbitrator's decision was irrational or tainted by fraud.

Some arbitration clauses are not enforceable, and in other cases arbitration may not be sufficient to resolve a legal dispute. For example, disputes regarding validity of registered IP rights may need to be resolved by a public body within the national registration system. For matters of significant public interest that go beyond the narrow interests of the parties to the agreement, such as claims that a party violated a contract by engaging in illegal anti-competitive conduct or committed civil rights violations, a court might find that the parties may litigate some or all of their claims even before completing a contractually agreed arbitration process.

United States.

In the United States, thirty-five states (notably not including New York) and the District of Columbia have adopted the Uniform Arbitration Act to facilitate the enforcement of arbitrated judgments.

Customer claims against securities brokers and dealers are almost always resolved pursuant to contractual arbitration clauses because securities dealers are required under the terms of their membership in self-regulatory organizations such as the Financial Industry Regulatory Authority (formerly the NASD) or NYSE to arbitrate disputes with their customers. The firms then began including arbitration agreements in their customer agreements, requiring their customers to arbitrate disputes.

Choice of law.

When a contract dispute arises between parties that are in different jurisdictions, law that is applicable to a contract is dependent on the conflict of laws analysis by the court where the breach of contract action is filed. In the absence of a choice of law clause, the court will normally apply either the law of the forum or the law of the jurisdiction that has the strongest connection to the subject matter of the contract. A choice of law clause allows the parties to agree in advance that their contract will be interpreted under the laws of a specific jurisdiction.

Within the United States, choice of law clauses is generally enforceable, although exceptions based upon public policy may at times apply. Within the European Union, even when the parties have negotiated a choice of law clause, conflict of law issues may be governed by the Rome I
