HRS §46-71
How to deliver legal papers to a county
This section says that legal papers (like a notice or court order) against a county can be given to the county's lawyer or their assistants, or in the way the county charter allows. Any officer who is allowed to serve papers can do this. Once served this way, the county is legally bound.

The statute, as written — Service of process upon county
Service of any notice or process issued against any county by any court, judicial or administrative officer or board may be made by any officer authorized to make service of process, and may be made upon the corporation counsel or county attorney or any of the corporation counsel's or county attorney's deputies, or as provided by the county charter. Any such service shall be binding upon the county.
