Advocate?

I am fond of calling myself an advocate.  When I speak for a client, their voice is heard.
There are people in this community that speak for others in their own voice, part of a plan of isolation and manipulation.
One of my disabled clients has been under my umbrella for more than a year and a half.  At this juncture I have to honestly admit that I know him not at all.
The family members and paid caregiver that share living space with this client contribute to an atmosphere of high emotion and confrontation. 
My ability to assist is hampered by the amount of funds available, the genuine risk of loss of public benefits if money is improperly expended, actions of previous trustees that established perceived precedents and the lack of cooperation from the client/circle to establish meaningful distribution goals.
When the client calls, I can hear an "advocate" in the background, coaching each word. 
My responsibilities are clear, my desire to provide assistance is genuine. My concern for the well being of this person is well-founded.
Is that enough?
