Paternity Lawyer
Paternity is the legal status of fatherhood. A child's biological father does not necessarily have legal parenting rights or legal responsibilities toward the child until paternity has been established.
Establishing paternity can be a difficult process without a legal advocate by your side.
Our board-certified paternity lawyers can protect your child's best interests.

The Many Benefits Of Establishing Paternity

Access to Child Support
Until the courts declare a man the legal father of a child, it is difficult to require him to pay child support, whether the parents were never married or are divorced.

Custody and Visitation Rights
A biological father will have difficulty achieving legal custody or fair visitation rights if he is not recognized as the legal father.

Knowledge of Medical History
In cases where the identity of the biological father is unclear, court-ordered DNA tests can prove fatherhood and give children access to important medical information.

Insurance and Other Benefits
A child cannot access their father's benefits such as health insurance, social security, and inheritance until legal fatherhood has been established.

Emotional Advantages
Paternity allows fathers to enjoy a relationship with their children, have a hand in the child's upbringing, and bond with the child.
Why Hire a Lawyer?
Unfortunately, disputes involving a question of fatherhood are often complex and quite difficult to resolve in an amicable way. In some instances, a man believed to be the father of a child may not wish to become responsible for paying child support, and therefore refuse to cooperate in any effort to resolve paternity issues. In others, a mother may not want a man believed to be the father of a child to have a relationship with that child.
A paternity lawyer can handle the legalities of your case and work toward an outcome that serves the best interests of the child. This allows you to cope with the stress of these disputes without the added challenge of navigating the legal system on your own. More importantly, a lawyer's knowledge of the laws pertaining to these disputes can greatly improve the chances that the child's best interests will be protected.
Whether your needs are related to a divorce, an adoption, a custody or visitation dispute, the need to collect financial support, or the need to eliminate the obligation to pay support, a paternity lawyer can help. David L. Cook and Donna J. Smiedt are Board-Certified Family Law Attorneys by the Texas Board of Legal Specialization.

Dealing With Mistaken Paternity

It can be devastating to find out the child you thought was yours may not be. After having this suspicion raised, it is totally understandable to no longer want the legal parent-child relationship you have had. Terminating this relationship will result in any future child support obligations being eliminated.
If you want to prove you are not the father, our attorneys can help you follow all guidelines laid out by the Attorney General of Texas for doing so. First, we can ensure you receive genetic testing from a lab that is certified by the Association for the Advancement of Blood & Biotherapies. Any test not from a certified lab will not count in court.
If the test comes back with the results you suspect, we can file a petition to end the parent-child relationship, make sure you meet all requirements at the pre-trial hearing, and represent you through the conclusion of this ordeal.
