In Texas, the earliest the court can enter a final judgment in your divorce is 60 days after filing (other states have different time frames). Most divorces include at least some dispute over valuing property, dividing property, assessing spousal maintenance, child custody, child support, visitation, and rights and duties with respect to the children. Many times those disputes lead the parties to the courthouse to settle them. So it is relatively unusual for a divorce to be granted on Day 61 in Texas.
Another reason a divorce may take longer than 60 days to resolve is if the wife is pregnant. In that case, the court will most likely wait until after the baby is born so that the final orders regarding the baby can be included in the divorce decree.
