Can an attorney force a client to put a two party check in his escrow account?

The attorney is required to have a two-party check issued and put in the escrow account. So, you're not the one putting the check into his escrow account, he is. Similarly, he can't hold back some of my money for a bill that you owe, but he can hold back some of your money for a bill that you owe. As for the doctor's lien, I don't know why there would be a lien if the bill was paid by insurance. And as you can see, the answer to the last question is "yes".
