Generally, in Texas, when a divorce goes to trial, it would be a bench trial in which the judge will issue a final decision on all matters of dispute. Texas is only one of the few states that grant a party the permission to request a jury trial during a divorce proceeding. The Texas Family Code limits the types of cases that a jury can hear and what type of decisions they can make. In an adoption suit or to adjudicate parentage, a party may not be allowed to ask for a jury trial. Concerning child support, terms on possession of and access to children, the rights of conservators except to choose the primary residence of children, and division of property, only a judge can deliberate and rule on these issues. A  jury can deliberate on and decide if there is any fault in a divorce, whether or not a property is separate or community-owned, which party can decide on the primary residence of a child, and any geographic limits regarding where the child may live.
When there is fault in a divorce and there are some strong emotional aspects to it that might come to play, a jury trial could be beneficial, because juries are community residents and may be swayed or influenced by emotions more than a judge would be. However, the party who believes the other is at fault could also run the risk of having the other party claiming the same things. Also, the threat of a jury trial could also encourage a settlement in an otherwise difficult divorce case. Keep in mind that jury trials are costly, because your attorney will need to make extensive preparations and tap other necessary resources to resolve your case. Furthermore, jury trials take time, extending the length or duration of your case, because it usually takes a while for such cases to be heard and deliberated on.
