An Act of God is a natural force outside of human control (such as an earthquake, tsunami, or hurricane), and may relieve a party or parties to a contract or agreement from having to perform their obligations. Such Acts of God are often addressed in a force majeure clause, which typically appears near the end of the contract or agreement. A force majeure clause may also excuse a party's performance of its obligations for other reasons beyond its control, such as unavailability of products, riots, civil unrest, pandemics, and terrorism.

In Wyoming, as in many other jurisdictions, an 'Act of God' refers to any natural event that is outside the control of humans and could not have been prevented or foreseen. Such events can include natural disasters like earthquakes, tsunamis, or hurricanes. When such an event occurs, it may relieve the parties to a contract from their obligations if performing those obligations becomes impossible or impracticable. This is often addressed through a force majeure clause in the contract. A force majeure clause is designed to protect parties from liability for breaches of contract when circumstances beyond their control arise. In addition to natural disasters, these clauses may cover other events such as pandemics, riots, civil unrest, and terrorism. The specific application of a force majeure clause depends on the language of the clause itself. Wyoming courts will interpret these clauses by looking at the actual wording of the contract and the circumstances surrounding the event that is claimed to have prevented performance. It is important for parties to a contract to carefully consider the inclusion and wording of a force majeure clause to ensure it reflects their intentions and provides the desired protection.
