Part 1 - How to start an Expert Witness Service business - Background

- Part 3 - Action plan to get started
What are the costs involved in opening an expert witness service?
The costs involved in opening an expert witness service business are minimal. Entrepreneur places the total cost of opening an expert witness business at between $2,000 and $10,000. The primary startup costs include:
-
rent for an office space
-
website costs
-
advertising fees
Business owners who want to reduce their initial expenses can run a business out of a home office. This eliminates rent for an office space, leaving website costs and advertising fees as the main startup costs.
A business’ website must look professional in order gain litigators’ trust. The average cost of a website is between about $2,000 and $10,000. (Purchasing a website on the higher end of this range may push a business’ startup costs beyond $10,000. Nice websites are often available on the lower end of the range, so business owners can keep their total expenses within Entrepreneur’s estimated range.)
Advertising costs can be matched to a business owners’ available budget. Business owners who don’t have much financial capital can grow their business slowly, investing more in advertising as they gain more clients.
What are the ongoing expenses for an expert witness service?
The ongoing expenses for an expert witness service business are low. They include any office lease payments, utilities, website hosting fees and advertising expenses. Businesses that have employees must also pay their employees’ salaries.
Who is the target market?
An expert witness service business’ ideal customer is a lawyer who regularly takes on similar cases that are closely contested. Such a lawyer will likely have a regular need for expert witnesses in the same field, which gives a business an opportunity to specialize in that field.
How does an expert witness service make money?
An expert witness service business may make money two different ways. It may collect a percentage of expert witness’ fees as a commission, and it can charge expert witnesses to be listed in its database.
How much can you charge customers?
The commissions that expert witness service businesses charge for connecting litigators with witnesses varies. Even modest commission percentages can be significant, though, because witness’ fees can easily be four- or five-figure sums.
The average hourly fee for non-medical witnesses is $275. Based on this figure, a witness may make $2,750 in just 10 hours of work. If a business collected a commission of just 20 percent, it’d earn $550.
As mentioned, some expert witness businesses also charge professionals listing fees. Businesses that collect a fee for including professionals in their database typically charge several hundred dollars per year. For instance, JurisPro’s fee for one year is $399. (Not all businesses charge listing fees.)
How much profit can an expert witness service make?
Some expert witnesses businesses are highly profitable, bringing in thousands of dollars each day. How much a particular business will make depends on how many clients it serves and its areas of specialty are. Six-figure revenues aren’t impossible to attain, although a business must have regular clients to reach such sums.
How can you make your business more profitable?
An expert witness service business can increase its profitability by offering training for expert witnesses. This helps ensure witnesses will meet litigators’ expectations, and many witnesses will pay for such training.
Day-to-Day and Growth
What happens during a typical day at an expert witness service?
Business owners spend much of their time fielding requests for expert witnesses from litigators and connecting them with qualified witnesses. Business owners develop lists of witnesses, so the matching process involves little more than looking up what witness meets a litigator’s requirements and introducing the two parties.
Before or during the initial introductions, contracts are signed by the litigator, witness and expert witness service business. Additionally, business owners are usually responsible for collecting payment from litigators and giving witnesses their due fees.
When not working directly with litigators and witnesses, business owners spend their time finding additional witnesses for their database and marketing their expert witness business.
What are some skills and experiences that will help you build a successful expert witness service?
In order to successfully match litigators with qualified witnesses, business owners must know what litigators are looking for in a witness. SEAK and the American Bar Association both have blog posts for lawyers who need expert witnesses. From these, business owners can glean some tips on what they should look for in the professionals they add to their database.
There are also books on becoming an expert witness. Expert Witness Training, The Expert Witness Handbook and How to Be an Effective Litigation Consultant and Expert Witness are a few broad titles for expert witnesses in any field. In addition to these, there are industry-specific books. Financial Expert Witness Communication and The expert Witness in Construction are a couple examples of industry-specific books for expert witnesses.
While these books are primarily targeted at professionals who want to become expert witnesses, many have insights that expert witness service business owners can benefit from.
Finally, The Expert Witness Marketing Book has tips that business owners can use to advertise their business.
What is the growth potential for an expert witness service?
Most expert witness service businesses have just one location, from which they may serve many areas. Rather than expanding by opening additional offices, businesses grow by branching into other areas of specialty and finding more witnesses. A business doesn’t need a physical office in a state in order to offer witness-finding services in that state.
For example, a business might start out with a database of expert witnesses who are familiar with insurance-related issues, and then add medical expert witnesses to its services. These witnesses can be added without opening a new location.
What are some insider tips for jump starting an expert witness service?
An expert witness service business must have a robust list of highly qualified professionals.
Business owners can find such professionals by partnering with expert witness courses. These courses prepare qualified individuals for work as expert witnesses, and the individuals have already expressed interest in this line of work. A company that offers courses may be willing to sell their class lists or showcase an expert witness business for a fee. SEAK offers one-on-one training and seminars, and Matson and Associates offers an online course.
Business owners may also find qualified professionals by cold-calling professors at colleges and universities. Even if they haven’t actively pursued becoming an expert witness, professors may be interested in supplementing their income with this type of work. They’re also typically qualified, because they’ve usually earned doctoral degrees and been published multiple times.
How and when to build a team
An expert witness service business can be run by a single person. If business becomes too much for one person to handle, an administrator may be hired. Additional employees can be hired as the business’ revenue supports hiring more people. Lots of expert witness businesses, however, remain small and don’t many hire employees.

Part 3 - Action plan to launch your Expert Witness Service business in 90 days
Nine concrete steps to take you from idea to open business, grouped into 30-day phases. Complete the planner above and we'll highlight what's most important for your situation.
First 30 days — Foundation
-
Form your legal entity
An LLC keeps your personal assets separate from business debts and lawsuits — the most common reason small business owners choose this structure. Sole proprietorships and partnerships do not provide this protection.
-
Get an EIN and register for taxes
Apply for your free Employer Identification Number through the IRS, then register for any state or local taxes that apply to your business (sales tax, franchise tax).
-
Open a business bank account and credit card
A dedicated business account is required to maintain personal asset protection. Mixing personal and business finances ('piercing the corporate veil') can void your LLC's liability shield.
-
Set up business accounting
Recording expenses and income from day one makes tax filing easier and lets you see when the business is actually profitable. Use software (QuickBooks, Wave) or a part-time bookkeeper.
Days 30–60 — Compliance & Risk
-
Get permits and licenses
State and local requirements vary widely. Brick-and-mortar businesses typically need a Certificate of Occupancy; service businesses may need specific professional licensing; food businesses need health permits.
-
Get business insurance
General Liability Insurance is the most common starting point. If you'll have employees, most states require Workers' Compensation. Specific industries need additional coverage (product liability, professional liability, etc.).
Days 60–90 — Launch
-
Define your brand
Your brand is how customers perceive and remember you. A clear name, logo, and visual identity make every later marketing decision easier and protect you legally as you grow.
-
Create your business website
Every legitimate business needs a website. Social media pages are not a substitute — you don't own the platform. Modern website builders mean you can launch a clean site in a weekend without a developer.
-
Set up your business phone system
A dedicated business number keeps your personal life private, makes the business look legitimate, and lets you route calls professionally. Cloud phone services start under $20/month.
