Process Service:

Reliable and accurate service of process for all your legal documents. Our agents use ServeManager, a software that tracks GPS position of process service.

Worker’s Compensation Investigation/Surveillance

Trusted and professional investigations into worker's compensation claims to ensure their legitimacy.


Domestic, infidelity, child custody, asset checks, criminal history reports, vehicle/tag searches, vehicle sightings report, surveillance, and others.

Scene Investigations

Scene of the accident, slip and falls, and other location-based investigations.

Witness Interviews and Statements:

Collecting and recording witness statements pertaining to investigations.

Skip Trace:

Locating and individual in order to conduct service of process.

GPS Tracker Rentals

High-quality GPS Trackers available for your use when legally permissible. Complete with training to fully understand any legal restrictions.

Notary Service:

Authorization of signatures on legal documents as an agent of the state. Certify signatures on your legal documents so contracts are upheld.

Criminal Background Checks:

Does a nationwide criminal background check exist?

Yes, and no. The only reliable and accurate way to perform a true national criminal background check would require someone to search in every county throughout all fifty States. With more than 3,000 available county-level sources to search from, it would not be cost-efficient.

However, we do offer a Unified Criminal Database Search that draws from millions of records from thousands of jurisdictions, including counties, Department of Corrections (DOC), Administrative Office of Courts (AOC), and offender registries from all 50 states.

As a busy litigator with a small private practice in Baltimore County, I have been extremely pleased with the "get-it-served" attitude -- and, more importantly, results -- that I have obtained from using Maverick Process Service to serve legal papers in both state and federal lawsuits.
Andrew D. - Attorney
Our firm has used Maverick Process Service for a little over six months. The service is outstanding and the costs are beyond reasonable. I would recommend Maverick Process Service to law firms seeking legal processing.
Deanna F. – Paralegal/Office Administrator
Maverick Process Service & Investigations, LLC is value added to my litigation practice for many reasons. In addition to being able to quickly serve my defendants, MPS has provided recon services that have enabled my clients to make informed decisions as to whether certain courses of action should be taken in cases. Additionally, I find their rates very reasonable.
Craig - Hunt Valley, MD Attorney
I am an office manager for a Finksburg Law Firm and I recommend Maverick Process Service to everyone. They are outstanding and top-notch. I have used various other process servers and this company has gained our commitment and trust. I have sent over many hard to find cases and Maverick Process Service has found every one of them. Previous servers have been unsuccessful. I rate them 5 PLUS STARS!! We are very happy and use only the BEST!! Our experience with Maverick Process Service has been very successful and they are wonderful to deal with.
Risa - Office Manager Finksburg Law Firm
We have been using Maverick Process Service for about a year now and have been extremely pleased. Their prices are reasonable, and I can trust that no matter what obstacles may present themselves, Maverick can handle any situation and will get the job done efficiently. They also keep us well informed of developments as they arise. I would highly recommend Maverick Process Service & Investigations, LLC to anyone in need of such services.

Maverick has consistently exceeded my expectations with their prompt service time and exceptional customer service.
Bradley R. - Legal Assistant
Brian, Sharon, and their team are extremely honest, unbelievably attentive, and they keep you up to date with what is going on with your matter without you having to ask. They are more than willing to take on a difficult job, then see it through no matter how many hoops they have to jump through to get it done. I can’t recommend using anybody else.
Matt R. Attorney, Baltimore, Maryland
Maverick is the best! In my 20 years of law practice in three counties, I have never found a comparable investigative service. Whether you need a simple skip trace, service of process, accident reconstruction, or surveillance - Maverick gets the job done and done well! Maverick is efficient, prompt, reliable, and wonderful to deal with. Maverick is my absolute ”go-to” PI.
Westminster Attorney
Once again, you guys ROCK!
Thanks so much!
Linda N.
I needed a quick turnaround on a summons in a pinch and Sharon and Brian were right on it and very responsive and communicative. The job was done very expeditiously. I can’t say enough good things about them. They’re good people, and true human beings and quickly considered my circumstances and handled it. I would seriously give them more stars if I could. I highly recommend them! Thank you to them!
Ben B.
I really appreciate all the work you guys do for us. Quite honestly, it’s remarkable and outstanding. It used to take longer and even harder to get status updates from the previous process server we used.
