Can a Constable's Office serve process in a lawsuit in which the County is a party? Rule of Civil Procedure 103 says the person serving process (1) cannot be a party to the suit or (2) be interested in the outcome of the suit. If, for example, the County needs to serve a notice of hearing in an eminent domain matter, can a deputy constable serve process? The constable's office has no direct interest in the outcome of the case, but the constable's office is also not it's own independent entity... Any thoughts are appreciated!
