Final answer:
The statement that assignment of the obligation to perform personal services is generally invalid is true, as these obligations are too personal in character to be transferred without the consent of the contracting party.
Step-by-step explanation:
Generally, the assignment of the obligation to perform personal services is invalid. This statement is true. Contracts for personal services are generally based on the unique skills, qualifications, or trustworthiness of a specific person. As such, these obligations are considered to be too personal in nature to be transferred or delegated to another party without the consent of the party who contracted for those services. For example, if a renowned artist is contracted to create a painting, the buyer typically expects that artist, and not a substitute, to perform the work. Therefore, an artist cannot assign the obligation to create the painting to another artist without the buyer's consent. This is true for many service-based contracts, including those involving artists, lawyers, doctors, and other professionals whose personal performance is crucial to the service being provided.
