Virginia Divorce ~ Proof of Residence
Your residency will be proved by your witness. The testimony of your witness is all that most courts require to verify residency. Some cases have been overturned or dismissed because of improper proof of residency. It is always necessary to give factual information in a court of law. It's a good idea to bring copies of your lease to court. It is possible that the county in which you file will require a sheriff's proof of residency, and in all Northern Virginia jurisdictions you may have to provide a valid Virginia driver's licence with your present address for the judge or commissioner to verify.
You can establish residency by registering to vote, your driver's licence, credit cards, library memberships, utility bills, etc. It is very important that you have sufficient proof of residency before you go to court.
