Why not charge a finder's fee? Particularly for the amounts over $1 million. Even at 1% fee that's tens of thousands of dollars that could be in your pocket.
The claim for in CT has a field to award a finders fee... assume it would be similar in other states, but it's up to the person to complete when then fill out the claim
In my state you have to file to have what is the equivalent of a 'finders license' to charge a fee, as well you're required to have a private investigators license. EVERY state is different.
