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.

* I am not an attorney licensed to practice law in Maryland. I am not allowed to draft legal records, give legal matters, including immigration, or charge a fee for those activities.

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.

Bank Record Search:

Current judgment document is needed to conduct this search.

First Responders Support

Maverick pays tribute to our Process Server, Eric Vargas, who lost his life in Ukraine, fighting for justice.



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.

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.

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!

Sharon and Brian,
I just wanted to take a moment to thank both of you for the incredibly high level of service you have provided to me and my clients over the last 6 months or more. Since the time I began using your company, you have helped me resolve communication issues with clients whom disappeared, and have served anything I needed served and filed the appropriate affidavits with the court, always letting me and my staff know the status of those activities.I could not be happier working with you and your company and I look forward to continuing to work with you in the future. Thanks again and I hope you both have a wonderful Thanksgiving holiday.
