An assignment for a claim of compensation under this chapter is void.
Compensation received under this chapter is exempt from the claims of creditors. This subsection does not apply in the case of a valid court order to garnish wages for child support or other lawful purposes.
A payment of compensation, schedule award, settlement payment, or any other payment made under this chapter shall not be delivered to any person other than the claimant entitled to that payment or that claimant's legal guardian unless the claimant has submitted a request in writing that the payment be delivered to another specified person, including the claimant's attorney, and which is not in violation of Section 2330 or any provision of the Act. This subsection shall not apply to attorneys' fees that a judicial entity may order the Program to pay an attorney under the Act.
