Condition Precedent vs Condition Subsequent

Short answer

The main difference between a condition precedent and a condition subsequent is timing. A condition precedent is an event that must happen before a party's duty to perform begins, such as obtaining financing before closing a purchase. A condition subsequent is an event that, if it happens later, ends or cancels a duty that already exists, such as a contract ending if a required license is revoked.

When condition precedent applies

A business uses a condition precedent when it wants to commit now but only perform once something is in place, such as signing a property purchase subject to financing and a satisfactory inspection. If the condition is not met by the stated date, the buyer can usually walk away without being in breach. Business acquisitions also rely on conditions such as regulatory approval before closing.

When condition subsequent applies

A business uses a condition subsequent when an existing deal should end if circumstances change, such as a distribution agreement that terminates if the distributor loses a required license. It protects the party that would be harmed by continuing after the change. For example, a sponsorship deal may end automatically if the sponsored athlete is suspended from competition.

Dates and deadlines to watch

Conditions precedent usually come with an outside date, sometimes called a long-stop date, by which the condition must be satisfied or waived, so check the contract. Missing that date often lets one or both parties terminate. Conditions subsequent may require prompt notice once the triggering event occurs, depending on the contract's wording.

Frequently asked questions

The obligation that depends on it generally never becomes due. Neither party is in breach just because the condition failed, and the contract may end or let a party terminate, depending on its wording.
