When Should I Hire a Personal Injury Lawyer?

In a perfect world, the person(s) liable for an accident will have an insurer who will give you the compensation you need to recover fully. Unfortunately, it’s not that simple.

Once an injury occurs, insurance companies will do all they can to settle for pennies on the dollar while releasing liability or delay and deny for as long as possible.

It is common for victims and their families to be shortchanged in their settlements, receiving a fraction of what they are rightfully owed and thus struggling to recover from their losses fully.

What if it takes a long time to recover? What if full recovery isn’t an option? Lost wages, medical expenses, vehicle repairs, and other related costs — injuries and medical bills are expensive!

Living with an injury is bad enough. Victims shouldn’t carry the debt of someone else’s negligence. Nor should they worry about how they will support themselves and their family in the future.

If you’re wondering when is the best time to hire a personal injury lawyer is, now is a great time to get in touch.

What to expect during the personal injury claims and lawsuit process


You’re injured due to someone else’s careless or negligent behavior

Personal injury attorneys make our communities safer by enforcing the “rules of the road” and holding insurance companies accountable.


You start the medical treatment you need

If you are injured, you should seek medical treatment immediately. Ensure your doctors know all your symptoms and complaints due to the injuries.

Insurance adjusters will not consider injuries without proper medical documentation.


Interview and hire the best personal attorney for your case

Call us to find out if we’re a good fit for your case. We’re easy to talk to and do not charge for a consultation.

Get a free case review

We can review your case with you and evaluate your best approach to ensuring that you receive the total and fair dollar amount for your claim.


Investigating and building your case

Your attorneys will begin working on your case immediately.

This includes contacting the insurance companies, gathering evidence, interviewing witnesses, and compiling the Demand Packet.


Communication throughout your case

Constant communication with our clients is one of the “keys to success” for successfully resolving a case. Keep your attorneys informed if anything changes in your medical treatment or if you have any questions throughout your case.

Phone calls, emails, and texting all work well for us.


Settlement or File a lawsuit

Once your doctors have released you, we compile a Demand Packet.

This includes everything related to your claim.

Insurance adjusters look for “value drivers” in evaluating claims. This includes medical treatment records, bills, and proof of lost income.

After discussing an initial settlement demand with you, we send the insurance company the demand packet and start negotiations.

If the insurance company is not offering a fair settlement, the next step is to file a lawsuit—the vast majority of personal injury cases that are filed end up settling.

Clayton T. Hasbrook

Clayton practices in general litigation, with an emphasis on personal injury law. In 2005, Clayton graduated cum laude from the University of Oklahoma with a Bachelor of Business Administration degree in Economics. While at OU, he served as the academics chair, treasurer, and president of his fraternity and as treasurer for the University of Oklahoma Young Democrats.

In 2008, Clayton earned his Juris Doctorate degree at the University of Oklahoma College of Law. He is admitted before all State Courts of Oklahoma and the Western District of Oklahoma. Clayton is a member of the Oklahoma Bar Association, Oklahoma County Bar Association, American Association of Justice, Oklahoma Association of Justice, Top 25 Motor Vehicle Trial Lawyers Association, and the National Trial Lawyers “Top 40 under 40.”

Focuses his practice on civil litigation. His primary emphasis is in the areas of personal injury and insurance law.

T. David Hasbrook

David attended the University of Oklahoma and obtained his undergraduate degree in Psychology in 1975 and his law degree in 1978. He then served over four years on active duty with the United States Army as a lawyer in the Judge Advocate General’s Corps. During this period, he gained valuable trial experience. After leaving active duty in 1982, David continued his military career in the United States Army Reserves until 2006, when he retired at the rank of Colonel.

Most of David’s practice involves representing people who are injured as a result of negligence. His cases are in both state and federal courts. He is admitted to practice before: all state courts in Oklahoma; the United States District Courts for the Northern, Eastern, and Western Districts of Oklahoma; the Tenth Circuit Court of Appeals; and, the United States Supreme Court. At times, he has been a member of the American Trial Lawyers Association, the Oklahoma Trial Lawyers Association, the American Bar Association, the Oklahoma County Bar Association, and the Oklahoma Association for Justice.

Although David’s practice is primarily in the injury law arena, his experience involves all aspects of civil litigation. In his initial practice of law in Oklahoma City, his emphasis was in business litigation, both for Plaintiffs and Defendants. He later found more satisfaction and enjoyment in helping injured individuals recover for their losses or damages. So, for the last twenty years, he has concentrated his practice in the areas of personal injury and insurance law.

Bryon Lakins

I couldn’t be happier with Clayton. He’s actually the second attorney I hired on my case. The first law firm had my case for a year and then said ‘here’s your settlement, we recommend it, and it’s all we can get you, but take it or leave it, this is a good settlement for your type of small case.’ It was barely anything. After parting ways with that law firm, I hired Clayton about a week or two later. He worked on my case more in one month than the previous law firm and was able to settle my case for close to 2x what the earlier law firm could do. He also charged less than what the other firm wanted….25 vs 40%. So, I was very happy with the result and to finally get my case over with – so frustrating!


Keep up the great work…they rocked.
