Which term describes a contract that can only be assigned with the other party's consent?

A personal contract is one that is inherently tied to the parties involved. Because of its nature, any assignment of the contract's rights and obligations typically requires the consent of the other party. This characteristic is essential in numerous scenarios such as agreements where trust, skill, or specialization are key factors, such as in contracts for services, leases, or certain trades.

In contrast, other contract types like aleatory contracts pertain to agreements where outcomes are based on uncertain events (like insurance) and do not necessarily involve party consent for assignment. Unilateral contracts involve one party making a promise in exchange for a performance from the other party, and while they may have stipulations, they are not directly associated with the need for mutual consent for assignment. Conditional contracts depend on specific conditions being met for them to be enforceable but do not inherently refer to party consent for assignment.

Therefore, the understanding of personal contracts highlights the importance of personal relationships and trust between the parties involved, which is crucial for determining the validity of any potential assignment of the contract.
