What does novation involve?

Novation is a legal concept that specifically refers to the process of substituting new obligations or parties in an existing contractual agreement. This involves replacing the original contract with a new one, where the original obligations are extinguished and replaced with new ones, or where one of the original parties is replaced by a new party.

This process is essential in contract law because it creates a new contractual relationship and relieves the original party from their obligations under the contract. For example, in a business scenario, if one party sells their interest in a contract to another party with the consent of the original party, a novation occurs.

In contrast, simply terminating a contract would end the existing obligations without replacing them, which does not reflect the concept of novation. Furthermore, establishing apparent servitude and claiming expropriated property pertain to specific legal rights and actions related to property law and do not involve the contractual modifications that novation entails. Therefore, the correct answer reflects the fundamental nature of novation within the spectrum of contract law.
