When Should You Hire a Criminal Defense Attorney in Houston?

If you are facing criminal charges in Houston, you should immediately hire the best criminal defense attorney possible. While you read this, the prosecutors and police are actively building their case against you. (Further reading: What to do if your friend gets arrested)

In many criminal defense cases, you will be taken to the local police or Harris County jail for booking, depending on the circumstances of your arrest. What happens in the next 24 to 48 hours is critical to your freedom and reputation. (Further reading: How to deal with going to jail)

What happens during your arrest is likely to be a blur: transport to jail and a Public Safety Assessment. Depending on your criminal record and personal history, you may not need to post a monetary bond, or post a smaller monetary bond. Those who fail to quickly post bond, or those with records / serious charges are likely to be held until hearing.

If you’re released prior to your hearing, and a Houston criminal defense attorney hasn’t been hired for you, it’s imperative to hire one now. Once hearings begin, only the best Houston criminal lawyers can help. Call Thiessen Law Firm 24/7 at 713-864-9000.
