2. In most cases, one party must file a petition for divorce in court. This can be done either through a lawyer or in some cases by filing papers with the county clerk’s office. After the petition is filed, the other spouse has 30 days to file a response. 3. If both parties agree to divorce, they may simply execute an agreement stating that their marriage is dissolved and provide copies to each other.
