The state of Texas requires a 60 day cooling off period before your divorce can be finalized. So, after the Original Petition for Divorce is filed, you have to wait 60 days before the divorce is final.

This doesn’t mean that the divorce has do be done on the 61st day. It just means that you can’t get divorced any faster than that. The divorce can be finalized any time after that (within reason.) If nothing happens for 6 months or so, the courts will sometimes dismiss the case.
