West Virginia Certificate of Service is a document that is issued by a court to a party or attorney in a civil case to prove that a court document was served to the other party in the case. This certificate is required in the state of West Virginia in order to ensure that all parties in a civil case are aware of the court documents related to the case and have the opportunity to respond to them. There are two types of West Virginia Certificate of Service: personal service, which is when the court document is delivered directly to the opposing party or their attorney, and substituted service, which is when the court document is delivered to another person or place in lieu of the opposing party or their attorney.
