Criminal Defense Law in Delaware: Overview
Delaware is a small state with a criminal justice system that has undergone notable reforms. The state abolished the death penalty in 2016 after the Delaware Supreme Court ruled its capital sentencing scheme unconstitutional in Rauf v. State. Delaware classifies felonies by letter grades (A through G) and misdemeanors by class (A through C and unclassified). The state follows a duty to retreat rule in public but provides Castle Doctrine protections within the home. Delaware decriminalized possession of small amounts of marijuana in 2015 and legalized medical marijuana, but recreational marijuana remained illegal as of early 2025 despite legislative efforts. DUI laws carry a 10-year lookback period with escalating penalties, and a fourth or subsequent offense is a Class E felony. Delaware has also implemented bail reform, adopting a risk-assessment-based pretrial release system. The state's habitual offender law imposes mandatory life imprisonment after a third violent felony conviction. Delaware was historically known for having a Court of Chancery, though this is more relevant to civil and corporate matters.

Duty to Retreat and Castle Doctrine
Delaware's self-defense laws are codified in Del. Code tit. 11, § 464. The state imposes a duty to retreat before using deadly force if the person knows they can retreat with complete safety, except in their dwelling. Within the home, a person has no duty to retreat and may use deadly force if they reasonably believe it is necessary to protect against death, serious physical injury, kidnapping, or sexual intercourse compelled by force or threat. Delaware does not have a Stand Your Ground law. The Castle Doctrine applies specifically to the dwelling and does not extend to vehicles or workplaces. Delaware courts apply an objective reasonableness standard to self-defense claims, meaning the jury evaluates whether a reasonable person in the defendant's position would have believed force was necessary.
Habitual Criminal Sentencing
Delaware's habitual criminal statute (Del. Code tit. 11, § 4214) is one of the more severe repeat offender laws in the country. Under § 4214(a), a person convicted of a Title 11 felony who has been previously convicted of three or more felonies may be sentenced to life imprisonment. Under § 4214(b), a person convicted of a violent felony who has two or more prior violent felony convictions must receive a mandatory life sentence without the possibility of probation, parole, or any form of early release. This "three strikes for violent felonies" provision has resulted in mandatory life sentences for a range of violent offenses. Delaware courts have upheld these provisions against constitutional challenges, though there have been legislative discussions about providing more judicial discretion.
Delaware Court System
Delaware's criminal courts include the Justice of the Peace Courts (handling minor misdemeanors and traffic offenses), the Court of Common Pleas (handling misdemeanors), and the Superior Court (handling all felony cases). Delaware is a small state with only three counties (New Castle, Kent, and Sussex), and the Superior Court sits in each county. Grand jury indictment is required for felony prosecution in Delaware. Appeals from Superior Court go directly to the Delaware Supreme Court, as Delaware does not have an intermediate appellate court. Criminal juries consist of 12 members and must reach unanimous verdicts. Delaware also operates specialty courts including Drug Court, Mental Health Court, and Veterans Treatment Court.
Damages & Penalties
Delaware classifies felonies as Class A (15 years to life), Class B (2 to 25 years), Class C (up to 15 years), Class D (up to 8 years), Class E (up to 5 years), Class F (up to 3 years), and Class G (up to 2 years). Misdemeanors range from Class A (up to 1 year in jail) to Class C (up to 3 months). Unclassified misdemeanors carry penalties specified in the defining statute. Delaware abolished the death penalty effectively in 2016 after the state Supreme Court struck down the capital sentencing statute in Rauf v. State as violating the Sixth Amendment right to a jury determination of facts necessary for a death sentence. The maximum sentence is now life imprisonment without parole. Fines for felonies can range up to $100,000 for Class A offenses.
Recent Legislative Changes
Delaware abolished the death penalty through judicial ruling in 2016 (Rauf v. State), and subsequent legislative efforts to reinstate it have failed. The state implemented its marijuana decriminalization law in 2015, reducing penalties for small-quantity possession to a civil fine. Recreational marijuana legalization bills have passed the House but stalled in the Senate. Delaware has expanded its expungement eligibility, with recent legislation allowing expungement of certain misdemeanor convictions after a waiting period. The state has also reformed its bail system to reduce reliance on cash bail for non-violent offenses.

Frequently Asked Questions
What are the penalties for a first DUI in Delaware?
A first-offense DUI under Del. Code tit. 21, § 4177 carries up to 6 months in jail (no mandatory minimum for first offense), a fine of $500 to $1,500, a 12-month license revocation, and mandatory completion of an alcohol evaluation and treatment program. Enhanced penalties apply for a BAC of 0.15% or higher, including a mandatory minimum of 7 days in jail for aggravated first offenses.
Is marijuana legal in Delaware?
Marijuana is decriminalized but not fully legalized for recreational use. Possession of 1 ounce or less is a civil violation carrying a $100 fine with no jail time and no criminal record. Possession of more than 1 ounce remains a criminal offense. Medical marijuana is legal for qualifying patients through the Delaware Medical Marijuana Act.
Does Delaware have the death penalty?
No. The Delaware Supreme Court struck down the death penalty statute in Rauf v. State (2016), finding that it violated the Sixth Amendment by allowing a judge, rather than a jury, to find the facts necessary for a death sentence. Legislative efforts to reinstate the death penalty have not succeeded.
What is the habitual criminal law in Delaware?
Under Del. Code tit. 11, § 4214, a person convicted of a third violent felony faces mandatory life imprisonment without the possibility of parole, probation, or early release. For non-violent habitual offenders with three prior felonies, the court may impose a life sentence but is not required to do so.
Can I get my record expunged in Delaware?
Yes. Delaware provides both mandatory expungement (for acquittals, dismissed charges, and successful completion of diversion programs) and discretionary expungement for certain misdemeanor convictions after a waiting period. Under Del. Code tit. 11, § 4372 et seq., you can petition the court for expungement. Violent felonies and sex offenses are generally not eligible.
Does Delaware have a Stand Your Ground law?
No. Delaware imposes a duty to retreat before using deadly force when the person can do so with complete safety. The Castle Doctrine exception applies only within one's dwelling, not in vehicles or workplaces. Outside the home, you must attempt to retreat if possible before using deadly force.
