Serving court papers in Maryland is governed by specific procedural rules that determine who may serve process, how service must be completed, and how proof of service must be filed with the court. Proper service is required for the court to exercise jurisdiction over a party. Defective service can delay proceedings or result in dismissal.
This page explains the legal requirements for serving process in Maryland under the Maryland Rules of Civil Procedure. It is intended for general informational purposes and does not provide legal advice.
Who Can Legally Serve Papers in Maryland?
Age, Status, and Disqualification Rules
Maryland law restricts who may serve court documents. To be eligible, a person must be at least 18 years old and may not be a party to the case. This requirement ensures neutrality and prevents conflicts of interest.
Maryland does not require private process servers to be state licensed. However, the absence of licensing does not reduce the level of procedural compliance expected. Courts apply the Maryland Rules of Civil Procedure strictly, and service errors can invalidate otherwise valid filings.
Under Maryland Rule 2-121(a) and Rule 3-123(a), service of process may be completed by:
- The sheriff
- A private individual who is at least 18 years old and not a party to the case
This applies in both Circuit Court and District Court matters. A party to the case may not serve their own documents.
Private Process Server vs. Sheriff
Maryland permits service by both sheriffs and private process servers. While sheriffs are authorized to serve legal papers, private process servers are often used due to greater scheduling flexibility, faster turnaround, and the ability to make multiple documented attempts within short timeframes.
The choice of server does not change the legal standard. All service must comply with the same procedural rules.
Methods of Legal Service in Maryland
The appropriate method of service depends on the case type, court, and party being served.
Personal Service
Personal service involves delivering documents directly to the individual named in the summons. This is the most reliable method and is permitted under Rule 2-121(a).
Substituted Service
If personal service cannot be completed, Maryland allows substituted service by leaving documents with a resident of suitable age and discretion at the individual’s dwelling. The server must document the identity of the recipient and the circumstances of service, as required by Rule 2-121(b).
Service by Certified Mail
In certain cases, service may be completed by certified mail with restricted delivery and return receipt requested. This method must comply with Rule 3-121 and is more commonly used in District Court matters.
Service by mail is not permitted in all cases. Courts may reject service if the return receipt is unsigned, incomplete, or improperly addressed.
Deadlines and Filing Proof of Service
Timing is critical in Maryland. Court documents must be served within the validity period of the summons. If service is not completed within that period, the summons may expire and require reissuance.
After service is completed, proof of service must be filed with the court. This filing documents when, where, and how service occurred.
For general guidance, litigants may consult the People’s Law Library of Maryland’s FAQs on service of process.
Serving Corporations, LLCs, and Other Business Entities
Service on business entities in Maryland follows separate rules and is frequently misunderstood.
Under Maryland Rule 2-124, service on a corporation, LLC, or partnership must generally be made on:
- The registered agent
- An officer, managing member, or partner, depending on the entity type
Attempting service at a business location without confirming the registered agent is a common cause of rejected service. If the registered agent cannot be located with reasonable diligence, the court may allow alternative service methods.
Proof of Service Requirements in Maryland
Service is not complete until proof of service is filed with the court.
Under Maryland Rule 1-323, proof of service must include:
- The name of the person served
- The date, time, and location of service
- The method of service used
- The name and signature of the person who served the documents
In Circuit Court, this is typically filed as an affidavit of service. In District Court, a certificate of service may be used depending on the method of service. Incomplete or vague proof is a common reason service is rejected.
District Court vs. Circuit Court Considerations
Although the core service rules are similar, procedural expectations can differ.
District Court cases more frequently permit service by certified mail, particularly in small claims and landlord tenant matters. Circuit Court cases more often rely on personal or substituted service and apply stricter documentation standards.
Always confirm the issuing court and follow the applicable procedural rules.
What Happens If Service Cannot Be Completed
If repeated attempts at service fail, Maryland courts may permit alternative service methods. This generally requires filing a motion demonstrating diligent efforts to locate the individual or entity.
Alternative service is not automatic and must be authorized by the court before proceeding.
What Happens If Someone Refuses Service?
Refusing to accept court papers does not necessarily prevent service.
If a process server follows proper procedures and documents the attempt accurately, service may still be considered valid. In some cases, refusal can result in delays or adverse outcomes for the defendant, including default judgments.
Professional servers are trained to document evasive behavior and comply with service requirements when recipients attempt to avoid service.
