So it is my understanding that the agreement between the client and the title insurance company is a contractual arrangement. And therefore the payment of a claim (or lack of payment) would be a contractual matter. So requesting all documents regarding any agreements between myself and Fidelity National Title seems reasonable and hardly irrelevant.
For example, as part of this I feel that all of the documents that I was provided at the meeting I had with the Fidelity National Title Officer in Napa California prior to purchase of the property regarding Parcels Two through Five (the subsequently lost easement) and research to obtain these documents would not only be relevant but IS the "subject matter of this action." And it was definitely part of the "agreement" which I had when I purchased the property namely that I had taken the additional step of meeting with the title officer to find out more about the parcels (easement), had obtained from him the recorded public records and understood these parcels (easement) to be a valid portion of my real estate purchase.
Additionally as cited previously from the Fidelity National Title website:
"When you purchase real property, rely on Fidelity National Title to protect your interests. You’ll be insured by a company backed by more than 150 years of successful title operations."
