Litigation is the most adversarial of all options available to you. It is also the most expensive. If your case involves domestic violence or intractable disagreement about how to resolve the necessary issues, you may have no choice but to litigate. Litigation may also be necessary if one or both parties are not being truthful about the information they are providing to the other side as they are trying to make agreements.
In litigation, one person files a complaint in circuit court stating their claims that support the grounds for divorce. The other person responds to the complaint with an answer and counterclaim.
