Our Attorneys

Sinkin Law Firm Attorneys

Our attorneys have helped establish numerous precedents in child support enforcement cases, such as eliminating the time periods to collect unpaid child support, making interest mandatory on missed payments and allowing children to enforce the unpaid support once their parent dies. Our attorneys have also helped broaden the tools to collect the unpaid support. Our extensive success in the trial courts, appellate courts and Supreme Court of Texas makes us different from other Texas law firms. See our client testimonials. In addition to the success in the courtroom, our attorneys have published and lectured across Texas on child support enforcement and collection. We are recognized by other Texas lawyers as unrivaled leaders in this area of law.
