Texas still allows a party to file for "fault" grounds in a divorce.
It generally goes to property division.
I've only seen once or twice a judge ordering a 100/0 split or a 90/10 split. That occurred when one party had a huge separate property estate and there was not much community property.
Generally the property division is 55/45 or 60/40.
The burden is on the person wanting more than 50% to "prove it" to the judge.
