(a) A person using this part shall serve interrogatories and legal process on the agent to receive process as explained in §582.201. Where the legal process is directed to an agency, and the purpose of the legal process is to compel an agency to garnish an employee's pay, the legal process need not expressly name the agency as a garnishee.

(b) Service of legal process may be accomplished by certified or registered mail, return receipt requested, or by personal service only upon the agent to receive process as explained in §582.201, or if no agent has been designated, then upon the head of the employee-obligor's employing agency. The designated agent shall note the date and time of receipt on the legal process.

(c) Parties bringing garnishment actions shall comply with the service of process provisions in this section. Service will not be effective where parties fail to comply with the service of process provisions of this section, notwithstanding whether the person bringing the garnishment action has complied with the service of process requirements of the jurisdiction issuing the legal process.
