While there’s nothing in the law that requires your spouse to sign off on a divorce judgment, it doesn’t mean that you’re stuck in the marriage. However, it will mean that the process will be longer because the Judge will actually have to Order the divorce after a hearing instead of the couple reaching an agreement and signing off on the settlement together and merely asking for the court’s approval. If your spouse is unresponsive to the petition you file initiating the divorce, then you can file for a default divorce, depending on what state you reside in.
You can file the paperwork at the county clerk’s office by yourself or with the assistance of a divorce attorney. Depending on where you live, you will have to pay a filing fee to initiate the divorce, but most counties will have an option to apply for a fee waiver if you meet certain financial requirements.
