Someone I know has been arrested. What can I do?
Call us immediately. We are one of the few firms who can write bonds for our clients in North Texas. We incorporate your bond fees into your retainer fee so you don’t have to pay for a lawyer and a bond company.
What if I’m unable to meet in your office?
We are fully capable of meeting via a computer or mobile through a secure portal. We can schedule conference calls and in certain circumstances come to you.
How do I know if I need a lawyer?
If you’ve been seriously injured by a vehicle, machinery, a company, or another person you need to hire an attorney immediately before the insurance company, company, or individual starts to build a case against you.
If you have been contacted by police, we believe you need a lawyer.
If you believe your spouse will file a family law action, or already has, you need a lawyer.
I’ve been injured but I’m not sure if I need a lawyer.
We are sorry you have been injured and hope you are recovering well. Since John has extensive experience in personal injury cases, he knows how to get results fast. Contact us as soon as possible and see why Texomans choose John to help them fight. Visit the Personal Injury Law area of our website to learn more.
How are custody orders modified?
A custody arrangement can be changed without going to court if both parents agree with the change (uncontested). If an agreement cannot be reached, then the court will decide (contested). The arrangement can also be changed by “default” if the other parent does not respond after being served or appear in court. Visit the Family Law area of our website to learn more.
How does your firm handle a divorce?
Divorce can be one of the most stressful events you and your family may experience. In any type of divorce, the complexities of the law, the amount of decisions required, and simply knowing there are many unknowns can overwhelm anyone. We understand this and respect the strength required during a divorce. When you choose us, you are choosing a firm that has the experience and compassion that you deserve. Visit the Family Law area of our website to learn more.
Can I pay legal fees over time?
Paying over time can make legal costs easier to manage. Ask the office about LawPay payment options for your case.
I have a court date or just received legal papers. How soon should I call?
Call promptly and mention the date or paperwork at the start of the conversation. Keep copies of everything you received.
What should I bring to the first meeting?
Start with court papers, upcoming dates, the county involved, and the names of the parties. Ask the office how to provide documents securely.
