One of the requirements to filing divorce in Texas is that you have lived here long enough. The court would not have jurisdiction if you do not meet these residency requirements. You have to be a domiciliary of Texas for the preceding 6 months prior to filing the divorce and a resident of the county in which you file for the prior 90 days.
The divorce court has the power to change the name of the person back to what it was before the marriage. Since Texas is a community property state, there will have to be a determination of the nature of the assets of the marital estate. Community property consists mainly of property acquired during the marriage unless a pre-marital or post-marital agreement states otherwise or if a separate property asset appreciates. The appreciation is a community asset.
