The allegations of the complaint hit a little below the belt, but aren’t unusual : Loyal mgr helped him and stood by him during difficult points in his career – got dumped when he reached his goals. ( Two series – Ray Donovan and Berlin Station).
What is unusual is that there seems to have been no written agreement for 11 years. In some states, there is what’s called a Statute of Frauds which requires that a contract for more than one year, must be in writing to be enforceable.
So, it is possible that the plaintiff cannot win on breach of contract claim for an oral agreement that stretches back a full 11 years.
What she may be entitled to is quantum meruit, an equitable, not a legal theory of relief. She would be entitled to the value of her services, which is a question of fact. I think that might be difficult figure for a talent manager. It doesn’t seem like she found the roles, as an agent might have.
