The firm boasts several board-certified family law specialists and has been voted “Best Law Firm” in Central Texas by local publications. Their approach combines the empathy required for sensitive child-related matters with the resources of a large, multi-practice firm. They offer comprehensive services for families going through transitions, including adoption and the pursuit of protective orders in domestic violence cases.
Family law in Texas is strictly governed by the Texas Family Code, which operates on the standard of the “best interest of the child” for all custody and support decisions. Texas is a community property state, meaning all assets and debts acquired during a marriage are generally owned equally by both spouses and subject to a “just and right” division by the court upon divorce. Under Section 6.702, there is a mandatory 60-day waiting period before a divorce can be finalized after the petition is filed. As of early 2026, families should be aware of the “Standard Possession Order” guidelines, which dictate visitation schedules unless the parties agree otherwise or the court finds a deviation is necessary.
