Answer ... The FAA does not prohibit an unrelated third party from funding a party in an arbitration. State law addresses third-party funding through:
- laws that regulate funders;
- the doctrines of maintenance, champerty and barratry; and
- rules regulating attorney conduct and the application of attorney-client privilege.
For example, American Bar Association Model Rule 5.4(a) prohibits an attorney or law firm from sharing legal fees with a non-lawyer, except in narrow circumstances.
