can you please answer this

All three attorneys can only bill for the flight.As stated in the "The Double Billing Dilemma", Double billing is against the ABA model A rule 1.5 (a) and 8.4.Attorney 1 is already doing being paid by the client to fly out to California, so therefor the attorney can not bill additionally for the hours he spent on the deposition questions.Attorney 2 is already being paid for the time to travel, so he can not bill another client for the same hours.Attorney 3 can bill for the flight as well since he is flying out to California on behalf of the client.

Model A rule 1.5 states that no unreasonable fees can be charged to a client.Double billing a client would be considered unreasonable feels and this is why it would break this rule.

Model rule 8.4 (c) talks about fraud and deceit.It would be fraudulent to double bill a client for hours and it would also be deceitful.
