Even if you win your case, the process may not be over. For more information about enforcing a court's judgment, see How to Enforce the Judgment If You Win. 
If you lose your case and disagree with the decision, you always have a right to appeal it. That means that you would have to present your case to another court, one that is it a “higher” level and has the authority to hear your case. If you lost your case in District Court, you may appeal to Circuit Court. If your case was in Circuit Court (even if it was an appeal from District Court), you may appeal to the Court of Appeals  in Annapolis.
The Court of Appeals is the state’s “highest” court, hearing appeals made from the Court of Special Appeals. (In rare cases, the Court of Appeals may choose to hear very important appeals directly, without having the case heard first in the Court of Special Appeals.) It is important to know that the Court of Appeals, unlike the process in the Court of Special Appeals, selects the appeals it wishes to hear—mostly those cases that present new legal situations.
If you are appealing a small claims case from District Court, you will have to present your case over again. Otherwise, in other situations, the Circuit Court or Court of Special Appeals will make decisions based on the evidence you presented in your original case. With this type of appeal, you will only be able to present legal arguments to justify why you believe you should have won your case. You will not provide evidence again to the court.
Because the appeals process, also known as the “appellate” process, takes some time and expense, a party should always take the time and re-evaluate his or her case. This is especially true because the appellate process usually involves complex legal arguments, rather than the presentation of evidence. If you handled your own case before, you should consider finding an attorney for the appeal. If you do handle your own appeal, you should expect to devote a significant amount of time to your case because you will have to write the reasons for your appeal based on legal research.
In order to start an appeal in a District Court case, the losing party must file a Notice of Appeal, Form DC/CV 37 , within 30 days of the entry of judgment. The party wishing to appeal, known as the “appellant,” files this notice of appeal with the District Court and also pays filing fees and a deposit for a transcript of the case, if one is necessary. As with every court filing, the party that files must make sure the other party is served properly. The appellant must pay filing fees to both the District Court and to the Circuit Court. Transcript preparation may be a significant expense—see the District Court’s Guide to Appeal Fees . However, it is important because the purpose of the transcript is to provide the Circuit Court with all of the information about the case. An appellant may file a Petition for Waiver of Costs, Form CC-DC 8 , but if the court does not grant the request, the appellant will have to pay for the transcript.
If the parties to the appeal can agree to a statement of the case, then the transmittal of the entire record may not be necessary. Maryland Rule 7-109 strongly encourages parties to agree to such a statement, which describes how the appeals questions arose and how the court decided them. Read the Rule: MD Rule 7-109 
If there is no agreed-upon statement, then the appellant will need to file a legal memorandum explaining his or her appeal. The other party to the appeal, known as the “appellee,” also may reply. Any party may request an “oral argument” in Circuit Court. Maryland Rule 7-113 covers many of these details, including the time for filing this paperwork.Read the Rule: MD Rule 7-113 
It is important to remember that the winning party may try to enforce a judgment during the appeals process unless the appellant takes certain steps. Because a judgment is stayed automatically only for 10 days, an appellant usually files a supersedeas bond (or some other “security”) with the District Court in order to continue the stay of judgment enforcement during the appeal. There are many details to this process, most of which are described in Maryland Rule 8-423. The Court has final authority to rule on the supersedeas bond. Read the Rule: MD Rule 8-423 
Appeals from Circuit Court cases can become quite complex. To appeal a Circuit Court decision, an appellant must file in the Circuit Court a Notice of Appeal, serve the other party, and pay the accompanying fee. (See the Revised Schedule of Circuit Court Charges, Costs and Fees .) The appellant must pay a filing fee  to the Court of Special Appeals as well. The appellant must file the notice within 30 days of the entry of the judgment and also must order the transcript from the court reporter and pay for the transcript. As in an appeal from District Court, an appellant likely will file a supersedeas bond with the lower court.
Then, 10 days after filing the notice, the appellant must file with the Clerk of the Court of Special Appeals a Civil Appeal Information Report, Form CSA1 , which must contain certain facts about the case. The Court of Special Appeals may order a pre-hearing or scheduling conference in order to set dates for filings and to address other matters. Or the court may order the parties to participate in mediation to give them an opportunity to resolve the issues in the case themselves, as opposed to having the court determine the outcome of their controversy, and to avoid the time and expense of an appeal. Otherwise, the court will order the appeal to proceed. In addition, parties may streamline the appeals by creating an agreed-upon statement of the case.
In many cases, the next step in a case appealed to the Court of Special Appeals is the writing of a “brief,” the formal legal arguments that state why the appellant should not have lost the case in Circuit Court. An appellant also must file a “record extract,” taken from the transcript of the Circuit Court record. There are many rules that define how an appellant should write the brief, the time for filing the brief and how many copies the Court requires. The appellee also must file a brief in response to the appellant’s brief. The rules that govern this very detailed procedure begin with Maryland Rule 8-501. The parties may also have the opportunity to participate in mediation at this stage of the appeal. A book, available in law libraries, entitled, Appellate Practice for the Maryland Lawyer, by Paul Sandler and Andrew Levy gives a comprehensive overview of appellate court procedures. Read the Rule: MD Rule 8-501  (Record Extract)Read the Rule: MD Rules, Title 17, Chapter 400  (Alternative Dispute Resolution in the Court of Special Appeals, Effective January 2014)
If the appeal to Circuit Court is for a small claim, then the new trial will be an informal one before a Circuit Court judge. If the appeal to Circuit Court is for another reason, then a Circuit Court judge will decide the appeal without any oral arguments, unless one of the parties requests it. The Circuit Court may decide the appeal in the following ways:
The Circuit Court judge will write a short opinion justifying the reasons for deciding the appeal. The opinion is sent to both parties and is filed in the Clerk's Office with all of the other paperwork from the case.
In the Court of Special Appeals each side presents an oral argument that is 30 minutes long. A panel of three judges will listen to the arguments, and one of the judges will write an opinion, which gives a detailed reason for the Court’s decision. Because it takes some time for judges to consider the case properly and to write an opinion, the parties may not know the outcome immediately.
A Court of Special Appeals decision still might not be in favor of the appellant. In that case, the appellant has a few options remaining. First, he or she may file a motion for reconsideration with the Court of Special Appeals, according to Rule 8-605. The second option is to file a "Petition for Writ of Certiorari" with the Court of Appeals. Certiorari is Latin, meaning "to be informed." In Maryland, this Petition is a formal, lengthy written request to the Court of Appeals asking for judicial review of the decision handed down by the Court od Special Appeals. There also is a filing fee. The Court of Appeals has significant discretion in granting appeals, accepting fewer than 20% of all petitions. If an appellant has a sufficiently unique legal issue—so that review is “desirable and in the public interest”—the Court will issue a writ of certiorari, and the parties will argue the case in a way similar to the procedures followed in the Court of Special Appeals.

Congratulations, you have gotten a judgment from the court! Now you need to enforce it.
First, you might want to read some general background on collecting judgment. There is a chapter on collecting your money judgment in Everybody's Guide to Small Claims Court  published by Nolo Press, a reputable California self-help legal publisher. Check with your county public library to borrow a copy or contact a law library  near you to find out if they have this title or a similar title.
Also, take a look at the booklet Post-Judgment Collection: How to Collect Your Judgment in the District Court of Maryland  from the Maryland District Court on the options on how to collect your money. This publication clearly describes steps you need to take.
Wage Garnishment. You may need to try to garnish the wages of the person who owes you money. The Maryland District Court Brochure on Wage Garnishment  offers “how-to” help on the topic.
Illegal Debt Collection. Under Maryland law, even if you are owed money, you are not allowed to act illegally to collect the debt owed to you.
When should you collect your judgment? In general, you should try to collect the judgment as soon as possible. As time goes by, it may be harder to keep track of the person who owes you money.
Wait until the appeal period is over. If you received a judgment in small claims court, you should wait at least 30 days until the appeal period has passed. Check with the court clerk to see if an appeal has been filed. Under MD Rule 3-534  the defendant has 10 days to make a motion to amend the judgment. Under MD Rule 7-104  the Defendant has 30 days to make an appeal.
Act before the time limit on collecting a judgment expires. Basically you have 12 years to collect your judgment. Courts & Judicial Proceedings § 5-102(a)(3)  However, you can renew the judgment by contacting the court again. MD Rule 3-625 . You must renew it before the judgment expires.
Judgments are satisfied by money paid to the plaintiff. When the defendant pays the amount owed to the plaintiff, the plaintiff has to give the defendant and file with the clerk a written statement that the judgment has been satisfiedRead the Rule: MD Rule 3-626 
In Maryland, there are a number of Administrative Agencies that have powers like the courts but are not part of the Maryland Judiciary. Administrative agencies include "any agency, board, department, district, commission, authority, commissioner, official, the Maryland Tax court, or other unit of the State or of a political subdivision of the State." (MD Rule 7-201 ) Some Maryland Administrative agencies include the Department of Health and Mental Hygiene, the Department of Human Resources, the Maryland Insurance Administration, the Department of Environment, and the Motor Vehicle Administration. Each agency has authority granted to them by the Maryland legislature for the area it oversees. Some of the powers that administrative agencies have include the power to issue licenses or permits, or to create regulations for businesses.
Under Maryland law, any party who is affected by an agency decision can petition for an administrative hearing. Many of the administrative hearings are conducted by the Office of Administrative Hearings (“OAH”). OAH conducts hearings for over 20 agencies and 200 programs. Administrative Law Judges (“ALJ”) conduct OAH hearings. ALJs are lawyers appointed by the Chief Administrative Law Judge and are not employees of the agency. The rules for procedure at an OAH hearing are in Title 28 of the Code of Maryland Regulations . At the hearing, the ALJ makes a decision based upon the evidence and argument presented.
Usually, parties must bring all issues and try every procedure that the agency has before filing for review in the circuit court. This is known as "exhaustion of remedies." The procedure for seeking review of the ALJ's decision will be included in the decision. In a few instances, a party may petition to the circuit court before exhaustion of remedies. Parties may petition to the circuit court if there is a nonfinal order by the agency that 1) determines rights and liabilities; 2) has immediate legal consequences; and 3) waiting for a final order would result in irreparable harm. A court reviewing an administrative agency's decision looks at the decision in "the light most favorable to the agency." The court cannot reverse the decision of an agency just because it would decide differently. The court will affirm the agency decision as long as the decision of the agency is reasonable given the evidence. Read the Law: MD State Govt. § 10-222 , MD Rule 7-201 – 7-209 
A person seeking review of an agency decision is called the petitioner. Unless another rule or law gives the petitioner more time, the petitioner must file a petition within 30 days after the date of the agency action, the date the agency sent notice of the agency action, or the date notice of the agency action was received, whichever is latest. Petitions for judicial review can be filed in the circuit court for the county where any party resides or has principal place of business. Advance filing fees must be paid at the time of filing, unless the case is an appeal from the State Workers' Compensation Commission or an appeal, by an individual claiming benefits, from a decision of the Board of Appeals of the Department of Labor, Licensing, and Regulation or the petitioner has gotten the fees waived. The court may waive, or put aside, the filing fee for people who cannot pay.
The caption, or beginning, of the petition must have the following format:
|IN THE CIRCUIT COURT FOR ________________
PETITION OF ____________________________
CIVIL ACTION No.________
The petition must explicitly "request judicial review," identify the action for which review is sought, and state whether the person seeking review was a party to the proceeding. Nothing else is required in the petition. A duplicate copy of the petition must be given to the clerk of the court to be sent to the agency.
If filing for review of a discussion of the Workers' Compensation Commission, then a copy of the petition must be served by the petitioner by first class mail to the Commission and each other party of record in the agency proceeding. Read the Law: MD State Govt. § 10-222(c) , MD Rule 7-202 , Md. Rule 7-203 , MD Ct. & Jud. Proc. § 7-201 
Filing a petition does not automatically stop the action of the agency. Petitioner has to file a motion with the court to stop the action of the agency until the court has ruled on the appeal. The court will tell the agency about the motion and hold a hearing before ruling on the motion. The court may require the petitioner to purchase a bond. Read the Law: MD State Govt. § 10-222(e ), MD Rule 7-205 
After receiving notice of the petition for judicial review, the agency will have 60 days to transmit a transcript of the agency proceeding to the court. The agency may request up to 60 extra days to get the record to the court. The petitioner will need to request and pay the initial cost for a transcript of the hearing. The petitioner can file a certification of the costs with the agency and the court may award the costs of producing the transcript to the petitioner if he wins the appeal.
Parties can avoid the cost of producing a transcript by agreeing to a statement of facts. The court encourages parties to agree to a statement describing the facts that are important to the questions the court is being asked to review. The clerk of the court will send notice to all parties after receiving the record. Read the Law: MD Rule 7-206 , MD Rule 2-603 
Within 30 days after notice of receiving the record is sent out, the petitioner must file a legal memorandum outlining the basis for his case. The memorandum must include a statement of the facts surrounding the case, the questions for review by the court, and an “argument,” or reason why the court should rule against the agency, on each question. The argument section should include references to the record of the proceeding. The argument should rely upon good legal reasoning and refer to case and statutory law. After the memorandum is filed, the agency and any other responding party will have 30 days to file responding memoranda.
Petitioners do not need to file memoranda in support of a petition for review of a decision of the Workers’ Compensation Commission because the circuit court reviews the evidence de novo. De novo means "anew;" the court will take a fresh look at the evidence. Read the Law: MD Rule 7-207 
The court will schedule a hearing to review the case no earlier than 90 days after the court received the record, unless all parties agree not to have a hearing. Normally, the court will make a decision based just on the record, but a party may make a motion to present additional evidence at the hearing. Hearings are held without a jury, unless the hearing is an appeal of a decision of the Workers' Compensation Commission. It is very rare for the court to take any new evidence unless the petitioner has evidence showing that the administrative officer did not conduct the hearing fairly.
After the hearing, the court may 1) send the case back to the agency; 2) affirm the agency’s decision; 3) modify the agency’s order; or 4) reverse the agency’s order. Read the Law: MD State Govt. § 10-222(h) , MD Rule 7-209 
These books can be found at many Circuit Court Libraries. Many contain sample documents useful in filing a petition. There are no forms for petitioning for judicial review of an administrative decision. Any potential petitioner who is not clear on what to do should consult an attorney. Circuit Court Clerks cannot give legal advice. A Clerk will not review a petition and acceptance by a Clerk does not mean that the petition meets all of the requirements of the law.
