Delaware Superior Court Rules: Civil, Criminal, and Appeals

The Delaware Superior Court rules are two separate rulebooks — one for civil cases, one for criminal — that control every step from filing through appeal in the state’s main trial court. They set what you must file, when, how the other side gets notice, what deadlines govern your response, how evidence is exchanged, and how a losing party gets a decision reviewed. The civil rules track the structure of the Federal Rules of Civil Procedure but carry Delaware-specific provisions that catch out-of-state attorneys off guard, and the criminal rules build a structured framework around a defendant’s constitutional protections.

Starting a Civil Case

A civil action begins when the plaintiff files a complaint and a praecipe with the Prothonotary, the court clerk’s office.¹ The praecipe is a short directive telling the Prothonotary which type of process to issue. Skip it and the Prothonotary will not issue a summons.

Every plaintiff must also file a Civil Case Information Statement with the complaint. The Prothonotary will not process the complaint for service without it, and missing the CIS can lead to dismissal.² Defendants carry the same obligation: file a CIS with the answer or first responsive pleading, or the filing can be stricken.

Service of Process

Filing gets the case on the docket. The court has no authority over the defendant until they actually receive the papers. Under the amended Civil Rule 4, the plaintiff prepares a form of process and files it alongside the complaint. The Prothonotary then issues the process by adding a signed and sealed version to the electronic docket. The plaintiff then delivers the documents to the county sheriff or a court-appointed process server for delivery to the defendant.³

Suing a business entity means serving its registered agent, not the CEO. Every corporation formed or doing business in Delaware must designate a registered agent to accept legal documents. If the agent has lapsed or refuses service, the court can authorize alternative methods. Sheriff’s fees are paid separately from the filing fee and vary by county.

Responding to a Complaint

A defendant has 20 days after service to respond. That response can be an answer that admits or denies each allegation, a motion to dismiss, or both. If the defendant appears in the case before formal service, the 20-day clock starts from the date of that appearance.

Civil Rule 12 gives defendants seven grounds for a motion to dismiss:

Lack of subject matter jurisdiction — the Superior Court is the wrong court for this type of case
Lack of personal jurisdiction — the court has no authority over this particular defendant
Improper venue — the case was filed in the wrong county
Insufficiency of process — the summons itself has a defect
Insufficiency of service of process — the papers were delivered incorrectly
Failure to state a claim — taking the complaint as true, there is no legal basis for relief
Failure to join a necessary party — someone who must be part of the case was left out

Failure to state a claim is the most heavily litigated ground. A defendant who wins ends the case without ever filing an answer. Ignoring the 20-day deadline risks a default judgment, where the court can award the plaintiff what they asked for simply because the defendant did not appear.

Pleading and Signing Standards

Superior Court follows notice pleading. Under Civil Rule 8, a complaint must contain a short, plain statement of the claim showing the plaintiff is entitled to some form of relief.¹ The point is fair notice, not proving the case on paper. Defenses must be equally concise, admitting or denying each allegation directly.

Civil Rule 7 defines the permitted pleadings: complaints, answers, counterclaims, cross-claims, third-party complaints, and replies to counterclaims. Documents that do not fit one of these categories are not pleadings, whatever the filer chooses to call them. Motions, briefs, and other papers follow separate rules.

Every filing must carry the signature of an attorney or, for a self-represented party, the party’s own signature. Under Civil Rule 11, that signature certifies the filing is not made for an improper purpose such as harassment or delay, that the legal arguments have support in existing law or a good-faith argument for changing it, and that factual claims have evidentiary support.⁴ Frivolous or misleading filings can draw monetary sanctions and have the document stricken.

Statutes of Limitations

File too late and the court will throw the case out no matter how strong the underlying claim. Delaware sets different deadlines by claim type:

Personal injury: two years from the date of injury⁵
Wrongful death: two years from the date of death⁵
Property damage: two years for personal property damage; three years for trespass or indirect property damage⁵
Breach of an unsealed contract: three years from when the cause of action accrued⁵
Written contracts over $100,000: the contract itself can set a longer limitations period, up to 20 years⁵
Construction defects: six years from the earliest applicable milestone date, such as substantial completion⁵

The clock generally starts when the cause of action accrues, usually the date of the injury or breach. Delaware recognizes a discovery rule in some circumstances that can delay accrual when the injury or the responsible party could not reasonably have been identified at the time. Courts still expect due diligence. If a straightforward investigation would have surfaced the problem, the period runs from when you should have found it, not when you actually did.

Civil Discovery

After the pleadings close, both sides exchange evidence and information. The available tools are written interrogatories, requests to produce documents, depositions, and requests for admissions. Discovery requests are served on the other party rather than filed with the court. Each side files a Notice of Service confirming the request was sent, with the date and method.¹

Personal injury cases move faster on the front end. Defendants must answer a standard set of interrogatories at the same time they file their answer to the complaint, cutting out weeks of back-and-forth.¹ Commercial cases assigned to the Summary Proceedings track are more constrained: each party gets up to ten interrogatories, up to ten requests for admissions, and up to four depositions, with fact discovery closing 180 days after the last answer is filed.

The duty to preserve evidence begins as soon as litigation is reasonably anticipated, before a suit is even filed. Destroying emails, text messages, or other electronically stored information after you should have known a case was coming can produce negative inferences at trial or case-ending sanctions.

Demanding a Jury Trial

A jury trial in Superior Court is not automatic. Under Civil Rule 38, any party who wants one must serve a written demand on all other parties no later than 10 days after the last pleading directed to the triable issue. If the demand is endorsed on a pleading, it must appear on the first page immediately after the caption. Miss the deadline and the jury right is waived; the case is decided by a judge alone.⁶ This is one of the shortest deadlines in the rules and one of the most commonly missed.

Alternative Dispute Resolution

Civil Rule 16.1, effective January 2018, established mandatory non-binding arbitration for eligible cases. The attorneys are responsible for meeting arbitration deadlines and managing the process, and the arbitration timeline runs separately from the court’s scheduling order so it does not push out trial preparation.⁷ Because the arbitration is non-binding, either side can reject the result and go to trial. In practice, the process forces early case evaluation and often produces settlement.

Criminal Cases

Criminal cases follow a separate rulebook. Under Criminal Rule 1, these rules govern all criminal proceedings in Superior Court and preliminary proceedings in lower courts when a judge sits as a committing magistrate for the Superior Court.⁸ The court handles felonies and other serious offenses beyond the jurisdiction of the Court of Common Pleas or Justice of the Peace Courts.

Criminal Rule 2 directs that the rules be interpreted to promote simplicity, fairness, and elimination of unjustifiable expense and delay.⁸ Judges rely on it to shut down procedural maneuvers that waste time without advancing either side.

A criminal case can start by indictment, complaint, information, or in some situations by arrest or summons without a warrant.⁸ An indictment comes from a grand jury; an information is a formal charge filed directly by a prosecutor. Criminal Rule 7 requires charging documents to contain a clear written statement of the facts making up the alleged offense, giving the defendant enough detail to prepare a defense.

Criminal Discovery

Discovery in criminal cases is governed by Criminal Rule 16 and is considerably more one-sided than civil discovery. On request, the prosecution must produce:⁸

Any written or recorded statements of the defendant or a co-defendant in the government’s possession
The defendant’s criminal record as known to the attorney general’s office
Books, papers, photographs, and tangible objects material to the defense or planned for use at trial
Physical, mental, or scientific examination results in the prosecution’s possession
The identity and expected testimony of any expert the prosecution intends to call

These obligations sit alongside the constitutional duty under Brady v. Maryland, which requires prosecutors to disclose any evidence favorable to the defendant whether requested or not. A Brady violation can produce a mistrial or an overturned conviction. Rule 16 covers much of the same ground through a structured request process, but Brady extends further and captures evidence the defense might not know to ask for.

Filing and Fees

Civil cases have required electronic filing since late 2007, when an administrative directive expanded e-filing to all new civil complaints, mechanic’s liens, and mortgage cases statewide.⁹ The system is File & ServeXpress, which handles document uploads, filing type selection, party designation, and electronic service on other parties.

After a document is submitted electronically, the Prothonotary reviews it and adds it to the official docket. The system generates a timestamped confirmation. All papers filed after the complaint must be served on other parties and filed with the court within a reasonable time. Service on attorneys is typically made by delivering a copy, mailing it to their last known address, or leaving it at their office with someone in charge.¹ Service by mail is complete upon mailing, not upon receipt.

Fees are collected at filing and are nonrefundable. A standard complaint for damages carries a $200 base filing fee, plus a $10 Court Security Assessment Fee on every initial civil filing, for a $210 minimum. Sheriff’s service fees are separate. Commercial cases in the Summary Proceedings track are billed at 0.5% of the amount in controversy, with a $200 floor and a $5,000 ceiling.¹⁰ In heavily litigated matters, an additional $245 fee applies after every 50 filings in a single action.

Computing Deadlines

Day-counting looks simple until a deadline lands on a Saturday or a holiday. The Delaware method: exclude the day of the triggering event, count forward, and include the last day of the period. If that last day is a Saturday, Sunday, or legal holiday, the deadline moves to the next business day. For periods shorter than seven days, weekends and holidays drop out of the count entirely, so a five-day deadline can span more than a calendar week.

Delaware legal holidays include the standard federal holidays plus any day designated by the Governor or the Chief Justice. When it is not clear whether the Prothonotary’s office is open, call ahead. A one-day miss because you assumed the office was open can end a case.

Appealing to the Delaware Supreme Court

Appeals from Superior Court go to the Delaware Supreme Court. In civil cases, you can appeal final orders from Superior Court judges. An order is “final” only when it resolves every issue in the case, including attorney’s fee disputes. An order deciding some but not all claims is interlocutory and generally cannot be appealed right away.¹¹

Criminal appeals are available when the sentence includes more than one month of imprisonment or a fine exceeding $100. The clock starts the day the defendant is sentenced, regardless of when the sentencing order actually appears on the docket.¹¹

The notice of appeal must reach the Supreme Court Clerk within 30 days. For criminal appeals, the 30 days start the day after sentencing. For all other appeals, the 30 days start the day after the trial court dockets the order. Every day counts, but if the last day falls on a weekend, a holiday, or a day the Clerk’s office is closed for weather, the deadline extends to the next open day. The 30-day period cannot be extended for any reason.¹¹
