My wife filed divorce , and then sold the house, can I get half the money/

In Texas, any property acquired during the marriage is deemed community property.  During a divorce, a court applies a "just and right" division of the property.  This doesnt mean 50/50, the court can split the community property 60/40, 70/30. The court applies factors in making this "just and right" division.  If your wife filed for divorce, then sold the house while the divorce is pending, you can claim that she commited "fraud on the estate" and seek to be reinbursed for your community share of the family home.
