Can I oppose a divorce in Florida?

Technically yes. If one of the parties denies that the marriage is irretrievably broken, then the court must give that party an opportunity to be heard on the issue. Practically speaking however, this will have very little effect. Because,Florida is a no-fault state, a party need only allege that the marriage is irretrievably broken and the court will usually order a dissolution of marriage as a result. The party opposing the marriage can possibly seek an order requiring that the couple attend counseling to save the marriage. However, the court can likely still find that the marriage is irretrievably broken if after the counseling there is still no improvement in the relationship or one of the parties still wants to pursue a divorce.
