What type of obligation is dependent on the occurrence of an uncertain event?

A conditional obligation is one that hinges on the occurrence of an uncertain event. This means that the obligation will take effect only when a specific condition is met or an event occurs. This can include situations where a party is required to perform only if a certain circumstance arises, thus making the obligation dependent on factors outside of their control.

An example of a conditional obligation would be an agreement to pay a bonus to an employee if the company achieves a certain profit level. Until that condition is satisfied, there is no requirement to fulfill the obligation of payment.

In contrast, an unconditional obligation does not depend on any event and must be fulfilled regardless of external circumstances. Affirmative obligations typically refer to positive duties or actions a person must undertake, while precedent obligations often relate to a sequence of obligations where one must be fulfilled before another can arise, which is a different concept than conditional obligations dependent on uncertain events.
