The One Day Divorce website shows the available mediation dates. You and your spouse will agree on a time via an on-line scheduling app. The date you and your spouse choose is the date that the mediation\arbitration will occur. The prep period is six week.
Soon after the conclusion of the scheduled mediation/binding arbitration, you will receive documents to e-sign. Once those documents are received back in the office, they will be filed with the court. The court may take a couple of days or a couple of weeks to review and sign the General Judgment of Dissolution. Once the Judgment is signed, you will be divorced.
In traditional divorce litigation, the attorney needs to prepare the initial documents, wait for a response, and then go through the process of discovery. There may be interim motions and hearings. The court may set a trial date after six months, and then you will learn that the court does not have a judge available on the day the court told you to show up. You will wait for months after that for a new trial date. Usually, it will take about one year to get to trial.
