Procuring cause claim by real estate agent

[littleJoe]

What is the name of your state? MA

I like to consult our experts here which I found are always helpful.
The real estate agent "A" and his client "C" has no contract signed. The agent "A" had introduced a small condo to "C" and had a lots of discussion about the unit , "A" also collected various related building information for "C". The client "C" later silently purchased the condo through another buy agent "D". The agent "A" believes he has the procuring cause to claim the compensation from the either "D" and/or "C".
Since the total compensation can fit small claim court, the agent "A" decides to file a small claim. Also the agent "A" contacted the agent "D", the agent "D" denied any knowledge of the existence of earlier agent of "A".
So now the question is, should the agent "A" file the claim againt the client "C" or the other agent "D"? How likely the agent "A" can win the case?

Thank you for your advices.

"Agent A" had no "client C". "Agent A" needs to make sure not to take shortcuts.

And "Agent A" has no contractual relationship with "Agent D" and will lose any lawsuit against "Agent D."

D is not an appropriate defendant since, pursuant to your story, D only acted as agent for C. It is impossible to opine intelligently about A's likelihood of success against C.
