Frequently,contracts contain ambiguous language that makes it unclear what is being assigned or delegated.Examples of ambiguous language are "I assign the contract" or "I assign all of my rights under the contract." When a court cannot clearly tell what the parties intended,the court usually considers the assignment to be both of rights and duties.In other words,when ambiguous language is used,the court considers that the assignor has assigned his rights and delegated any duties he had under the contract.Doing so removes any right the assignor had to collect under the contract,but he is still liable to the obligee for any duties the delegatee,who is also the assignee,fails to perform.
