What is A Lay Witness?

The term “Lay Witness” is commonly used among lawyers in order to differentiate from an Expert witness. But you already knew that.

Besides lawyers, attorneys and paralegals, Lay witnesses hold a vital role so much that entire cases have turned on the credibility of a single lay witness.

Why Do I Need A Lay Witness? 

When dealing with a legal case and multiple charges, you need to prove a few key things in order to win your case.

1. Find evidence or proof that the other party (the defendant) was negligent or careless.
2. Also, you need to prove that you were harmed because of this carelessness. Prove your damages. 
3. Finally, you need to connect negligence to the harm. Usually, the Expert witnesses take care of this part. So, this is for another topic.

People usually prove 1 & 2 with the help of the testimony of a Lay witness, someone who saw or knows something important about your situation.

In most cases, lay witnesses are said to be able to help lawyers and their clients prove both the carelessness and the harm caused.

Best Way To Identify Good Lay Witnesses For Your Injury Claim!

You are dealing with a complicated case AND you have to win? Then, choosing the right lay witness can make a big difference!

So, what makes a lay witness ideal? Don’t worry, we have done the legal research for you!

First, start with shortlisting the people who know you well but NOT TOO WELL.

A potentially credible lay witness is typically a coworker, neighbor, gym buddy, or someone from your community group.

Basically, you need to find someone who has seen your routine before and after the injury but isn’t so close that their testimony could appear biased. 

Here is what a strong Lay witness should be:

• Personal knowledge of your life before and after the injury: they need to be able to express how much your behaviour, mood or social activities have changed since the harm. 
• Credibility and Neutrality: Someone without emotion or financial relationship with you makes them a strong witness. Juries trust objective observers over family or close friends. 
• Clear Communication: A strong lay witness should be able to explain what they have seen in simple and honest terms without over exaggeration or confusion.
• Consistency: If you have more than one lay witness, then their version of events should align with your medical records, your own testimony and the timeline of your case. 

When deciding on a lay witness, get your litigation intake attorney on board. Also, don’t forget your friendly neighborhood community connections. For instance, you church group member, your hairdresser, even your gym buddy might notice things that speak volumes about how your injury has changed your everyday life.

All in all, the best lay witnesses are those who can offer firsthand, believable, and emotionally grounded insights on the effect the injury has on you without sounding exaggerated or biased.

Qualities of an Effective Lay Witness

An acceptable and effective Lay witness would be someone with strong personal knowledge and perception.

For instance, they have the ability to testify exactly what they personally saw, heard or experienced. Their statements cannot be based on speculation or assumptions but their own perceptions.

In addition, the Lay witness must have good communication skills, they must be able to explain their observations clearly and audience-friendly language.

AND they are required to be good listeners so that they can answer the questions asked, loudly and clearly, without rambling.

Furthermore, the most crucial quality of a lay witness is their credibility and integrity. They are sworn to tell the truth and stick to it. Their statements CANNOT be biased or consist of personal opinions. 

A lay witness’s confidence and composure in front of the court is vital to ensure their testimony is believable. Moreover, their statements need to be consistent or else it might damage their credibility. 

Also, a lay witness needs to come prepared to a hearing and show professional mannerism.

Lastly, they need to understand the power their testimony holds at court. 

How Lawyers Prepare Lay Witnesses for Trial

Lawyers usually share a CHECKLIST with Lay witnesses to help them prepare themselves before the trial.

You can customize your checklist based on your needs and maybe even add more details. If you need help, I would recommend you seek out paralegal services.

1. Understand Your Role and Tell the Truth
