Delaware court rules are published separately by each of the state’s six courts, and the right set for your situation depends on which court has jurisdiction. The Supreme Court, Court of Chancery, Superior Court, Court of Common Pleas, Justice of the Peace Court, and Family Court each maintain their own rulebook covering filing procedures, deadlines, fees, service requirements, and appeals. Using the wrong court’s rules is one of the most common and most preventable mistakes in Delaware litigation.
Finding the Right Rulebook
The current rules for every Delaware state court are posted on the Delaware Courts website.1Delaware Courts. Rules of the Delaware State Courts Before you look up anything else, confirm which court actually has jurisdiction over your matter. The dividing lines are mostly subject matter and dollar amount:
- Supreme Court: appeals from the lower courts.2Delaware Courts. Introduction to the Delaware Court System
- Court of Chancery: corporate governance, trusts, fiduciary disputes, injunctive relief, and other equity matters. No jury trials.
- Superior Court: major civil claims and all felony criminal cases.
- Court of Common Pleas: misdemeanor criminal cases and civil disputes up to $75,000.3Delaware Courts. An Overview of the Delaware Court System
- Justice of the Peace Court: minor criminal offenses and civil disputes up to $25,000, excluding physical injury cases.4Delaware Courts. Jurisdiction – Justice of the Peace Court
- Family Court: divorce, custody, child support, juvenile proceedings, protection from abuse, and related domestic matters.
Once you have the right court, the Administrative Office of the Courts also publishes standardized forms that correspond to each court’s rules and formatting requirements.
Electronic Filing: Two Systems
Delaware runs two separate e-filing platforms, and filing in the wrong one means your documents never reach the court. File & ServeXpress handles the Supreme Court, Court of Chancery, and Superior Court. The eFlex system handles the Justice of the Peace Court and the Court of Common Pleas. Both require you to register an account before submitting anything, and training resources for each are linked from the courts’ e-filing page.5Delaware Courts. Electronic Filing in the Delaware Judiciary
Starting a Civil Case
Court of Chancery
A Chancery case begins with a verified complaint filed with the Register in Chancery, along with a supplemental information sheet. “Verified” means the filer swears under oath or affirms that the contents are true and correct to the best of their knowledge. The same verification requirement applies to counterclaims, crossclaims, and amendments.6Delaware Courts. Rules of the Court of Chancery of the State of Delaware – Rule 3
Most Chancery actions require a nonrefundable deposit of at least $410, with the exact figure depending on the case type and number of defendants. Trust matters, guardianships, partition actions, and probate proceedings are exempt from the deposit. A technology surcharge and a court security fee also apply.
Superior Court
A Superior Court civil case starts with a complaint, a praecipe directing the Prothonotary to issue the writ, and a Case Information Statement that categorizes the dispute and identifies the parties.7Delaware Courts. Rules of Civil Procedure for the Superior Court of the State of Delaware – Rule 3 The standard filing fee is $200. For cases subject to summary proceedings in commercial disputes, the fee is 0.5% of the amount in controversy, with a $200 minimum and a $5,000 maximum.8Delaware Courts. Civil and Criminal Fees – Superior Court
Court of Common Pleas
Common Pleas requires three documents to open a civil case: a complaint, a praecipe, and a summons. The complaint must describe the dispute in short, numbered statements and state the dollar amount sought. Bring the originals plus one copy for each defendant. The filing fee is $85, plus sheriff’s fees for service.9Delaware Courts. Court of Common Pleas Civil Trials
Justice of the Peace Court
You can represent yourself in the JP Court. Cases start with a complaint form from the court’s website or counter. Filings go through eFlex, and certain filers are required to submit electronically under the court’s policy directives.10Delaware Courts. Civil Court Proceedings – Justice of the Peace Court A technology fee of $1.25 per document applies to electronic filings.5Delaware Courts. Electronic Filing in the Delaware Judiciary
The 120-Day Service Deadline
In Superior Court, the plaintiff has 120 days from filing to serve the defendant. If service isn’t completed and the plaintiff can’t show good cause for the delay, the court must dismiss the complaint without prejudice.11Delaware Courts. Rules of Civil Procedure for the Superior Court of the State of Delaware – Rule 4 The Court of Common Pleas enforces the same 120-day window. In Common Pleas practice, if you don’t hear back from the court about service within roughly two weeks of the sheriff’s attempt, follow up to confirm whether service was completed.
Responding to a Complaint
In the Court of Chancery, a defendant has 20 days from service to file an answer. If the defendant instead files a motion to dismiss and the court denies it, the defendant has 10 days from notice of that ruling to file a responsive pleading.12Delaware Courts. Rules of the Court of Chancery of the State of Delaware – Rule 12 Missing the 20-day window risks a default judgment.
Once a Superior Court defendant responds, the court issues a scheduling order that sets deadlines for discovery, expert disclosures, and trial. That order governs the rest of the case and is rarely modified without a strong showing of good cause. Missing a scheduling order deadline can result in sanctions or the loss of a right to present certain evidence.
Appealing to the Delaware Supreme Court
A notice of appeal must be filed within 30 days of the lower court’s judgment in both civil and criminal matters. The 30-day deadline is strict. For challenges to arbitration awards under the Delaware Rapid Arbitration Act, the window is 15 days.13Delaware Courts. Rules of the Supreme Court of the State of Delaware
The filing fee is $500, plus a $10 court security assessment. Both are nonrefundable. Appeals from the Industrial Accident Board and the Unemployment Insurance Appeal Board are exempt from the filing fee.14Court Rules Network. Rule 20 – Fees and Costs, DE Supreme Court The notice must clearly identify the parties and the specific order being challenged.
Briefing Deadlines
The appellant’s opening brief and appendix are due within 45 days of the notice of appeal if no transcript was ordered. If a transcript is part of the record, the opening brief is due 30 days after the record is filed. The appellee has 30 days after receiving the opening brief to file an answering brief. The appellant has 15 days after the answering brief to file a reply.15Delaware Courts. Rules of the Supreme Court of the State of Delaware – Rule 15
The Clerk will not accept a late brief without leave of court, and the court may dismiss the appeal entirely if the appellant files late. Attorneys who repeatedly file late motions for extensions risk disciplinary action.
Cross-Appeals and Rehearing en Banc
A cross-appeal must be filed within 15 days of the first notice of appeal, or within 30 days of the judgment, whichever is later.16Delaware Courts. Rules of the Supreme Court of the State of Delaware – Rule 6 This is a narrower window than the original 30-day appeal deadline, and missing it forecloses the ability to challenge the lower court’s ruling on separate grounds.
After a three-justice panel issues a unanimous decision, a party has 15 days to move for rehearing en banc. The motion must show one of three things: the case raises an exceptionally important question, full-court review is needed to keep Supreme Court decisions consistent, or the panel relied on a prior decision that should be reconsidered. Granting rehearing requires at least two affirmative votes from qualified justices. If a panel cannot reach a unanimous decision on its own, the case goes to the full court automatically.17Delaware Courts. Rules of the Supreme Court of the State of Delaware – Rule 4
Family Court Jurisdiction and Protection From Abuse
Family Court has exclusive jurisdiction over divorce and annulment, custody and visitation, child support, juvenile delinquency, child abuse and neglect, protection from abuse petitions, and consent matters for minors such as medical care or military enlistment.18Delaware Code Online. Delaware Code Title 10 – Chapter 9, Subchapter II These cases do not go to Chancery, Superior, or Common Pleas, even when they involve money or property.
Protection from abuse petitions are limited to petitioners with specific relationships to the alleged abuser: current or former spouses, people who lived together as a couple, co-parents, people in a current or former dating relationship, and certain family members. Other relatives by blood, adoption, or marriage qualify only if they live in the same household.19Delaware Courts. Protection From Abuse – Family Court The court provides an instruction packet for PFA petitions, and its Domestic Violence Advocacy Program can be reached at 302-255-0420.
Standing Orders From Individual Judges
The published court rules are not the only rules that apply to your case. Once a case is assigned, check the assigned judge’s individual page on the Delaware Courts website. Most judges publish standing orders that supplement the general rules with their own management preferences.
Common requirements include delivering physical chamber copies of motions and briefs within a set time after electronic filing, submitting searchable PDFs with digital bookmarks for exhibits, and following specific formatting for proposed orders. A judge can refuse to consider a noncompliant filing or strike a motion from the record. Because these requirements vary by judge, review the standing orders as soon as you learn your case assignment.
