Types of Divorce & Family Cases We Handle


Texas has very complex divorce laws and requirements for dissolving a marriage. Make sure you have the guidance of a Dallas family law attorney who has your best interests in mind.

To get a divorce in Dallas, you must meet the residency requirements, undergo a waiting period after filing, and have a reason for your divorce. Texas recognizes no-fault divorce, so you can get a divorce due to “irreconcilable differences” or for other reason, such as adultery or cruel treatment. Our family lawyers can explain every step in detail and make the divorce process as smooth as possible.

Child Custody

Conservatorship,” as it’s called in Texas, is a major part of any divorce involving children. Your children’s emotional, mental, and physical care needs to be protected during and after a divorce. Our family lawyers in Dallas can help you fight to protect your child’s best interests. This could take the form of joint managing conservatorship if you and the other parent are prepared to co-parent your children, or sole managing conservatorship if it is in your children’s best interests to remain in your care alone.

Same-Sex Divorce & Custody

Divorce and custody is even more complex for same-sex couples since same-sex marriage and divorce has far less history. Our family law attorneys in Dallas are experienced advocates for the rights LGBT individuals in same-sex divorces and same-sex custody disputes.

Child Support

In a Texas, both parents are required to financially support the child after a divorce. This means that child support will need to be decided either through an agreement or by a judge. Having a Dallas family law attorney on your side to argue your case is a vital for obtaining a fair support order.


After a divorce, it is often necessary to petition the court to enforce an order of support or custody. Get in touch with our Dallas family lawyers immediately if your ex has stopped paying alimony or child support, or if they are preventing you from seeing your child. Our team can advocate for you as you seek to enforce court-ordered support or access to your child.


Another vital part of any Texas divorce or conservatorship case is the establishment of paternity. While mothers automatically have parental rights at the time their child is born, fathers in Texas must establish paternity, either voluntarily or with a paternity test, in order to protect their parental rights. We can help you establish paternity and fight for your rights regarding your children.

Prenuptial & Postnuptial Agreements

Does your marriage involve a high net worth? Whether you are not yet married or have already said your vows, a marital agreement can give you and your partner peace about the future. Prenuptial agreements and postnuptial agreements are a tool to help you protect your hard-earned legacy.
