Choice of law is a procedural stage in the litigation of a case involving the conflict of laws when it is necessary to reconcile the differences between the laws of different legal jurisdictions, such as sovereign states, federated states (as in the US), or provinces. The outcome of this process is potentially to require the courts of one jurisdiction to apply the law of a different jurisdiction in lawsuits arising from, say, family law, tort, or contract. The law which is applied is sometimes referred to as the "proper law." Dépeçage is an issue within choice of law.
