If you live in Wilmington and are starting a divorce, your case runs through the Family Court of the State of Delaware in New Castle County, housed inside the Leonard L. Williams Justice Center at 500 N. King Street downtown. A Wilmington divorce lawyer guides you through Delaware's no-fault separation requirement, equitable property division under 13 Del. C. § 1513, and child custody under the best-interests standard of 13 Del. C. § 722. The total court cost to open a case is $175, and the court will not finalize a no-fault divorce until you and your spouse have been separated for at least six months.
Wilmington sits at the northern tip of Delaware, and nearly every divorce filed by a city resident lands at the King Street courthouse, a short walk from Rodney Square and the Brandywine. The same building handles New Castle County matters for residents from Brandywine Hundred down to Newark, so expect company in the Resource Center on filing days.

How do I file for divorce in Wilmington, Delaware?
To file for divorce in Wilmington, you submit Form 442, the Petition for Divorce/Annulment, to the New Castle County Family Court at 500 N. King Street and pay the $175 fee as of March 2026. You must already be separated, and either spouse must have lived in Delaware for six months under 13 Del. C. § 1504.
The practical steps for a Wilmington resident look like this. First, confirm you meet the residency rule and that you have been separated. Delaware allows separation under the same roof, so long as you and your spouse keep separate bedrooms and abstain from sexual relations. Second, complete the Petition for Divorce/Annulment (Form 442) along with the required information sheets, which the court's instruction packets explain step by step. Third, file at the King Street courthouse Resource Center or by mail, paying by cash, check, or money order to "Family Court." Fourth, arrange service on your spouse, which costs an additional $10 to $100 depending on method. The court will not sign the final decree until the six-month separation period has passed, per 13 Del. C. § 1507, unless you file on misconduct grounds such as adultery or abuse, which removes the separation timeline.

Delaware imposes no separate county-residency requirement beyond the six-month statewide rule, so you file here even if your spouse has moved out of New Castle County, as long as one of you still lives in Delaware.

How much does a divorce lawyer cost in Wilmington?
A Wilmington divorce lawyer generally charges $250 to $400 per hour, with most attorneys requesting a retainer of $2,500 to $5,000 up front. An uncontested no-fault divorce often resolves for $1,500 to $3,500 in total legal fees, while a contested case involving custody or significant assets commonly runs $7,000 to $20,000 or more.
The biggest cost driver is conflict. If you and your spouse agree on property, support, and parenting, much of the lawyer's time goes to paperwork and one or two hearings, keeping fees low. Disputes over the marital home, retirement accounts, or a custody schedule multiply the hours quickly. On top of attorney fees, budget the $175 court filing fee, $10 to $100 for service of process, $5 to $25 per motion, and $10 for each certified copy of the decree. Low-income Wilmington residents can avoid the filing fee entirely by applying to proceed in forma pauperis using Form 257P, which the court grants when household income is at or below 150% of the federal poverty level. Many local firms offer flat-fee uncontested packages, and a free initial consultation is common, though it is never guaranteed. To estimate your full exposure before hiring, run the numbers with the divorce cost estimator.
How long does a divorce take in Wilmington?
An uncontested no-fault divorce in Wilmington typically takes about six to eight months, driven by Delaware's mandatory six-month separation period before the court signs a decree. Contested cases involving custody, support, or property disputes commonly stretch to 12 to 24 months as hearings are scheduled at the New Castle County Family Court.
The separation clock, not the courthouse calendar, sets the floor for most filings. Under 13 Del. C. § 1507, you may file the petition before the six months elapse, but the judge cannot grant the divorce until the separation requirement is met. Once that period passes and the paperwork is complete, an uncontested matter can be decided on the documents without a full hearing. Contested cases require ancillary proceedings for property division and support, plus separate custody hearings under 13 Del. C. § 722, each of which adds months to the New Castle County docket. Filing on misconduct grounds removes the separation wait but typically increases conflict and overall duration. To map your own schedule, the divorce timeline tool walks through each stage.
What are the residency requirements to file in New Castle County?
To file for divorce in New Castle County, either you or your spouse must have lived in Delaware continuously for at least six months immediately before filing, under 13 Del. C. § 1504. Military members stationed in Delaware for six months also qualify, even if their legal domicile is another state. There is no separate county residency rule.
This statewide standard means a Wilmington resident does not need to prove they lived specifically in New Castle County, only that one spouse has been a Delaware resident for the half-year window. The requirement attaches to either party, so even if the filing spouse recently moved away, the case can proceed when the other spouse still meets the six-month threshold. Delaware also treats separation flexibly. The state recognizes separation even when spouses share the same home, provided they sleep in separate bedrooms and stop marital relations, which lets many Wilmington couples begin the clock without one party paying for a second residence.
How is property divided in a Wilmington divorce?
Delaware is an equitable distribution state, so the New Castle County Family Court divides marital property fairly rather than automatically in half, under 13 Del. C. § 1513. Property acquired by either spouse during the marriage is presumed marital regardless of whose name holds title, and the court weighs factors like marriage length, income, and each spouse's contributions.
The court considers the length of the marriage, the age and health of each spouse, income and earning capacity, the contribution of each party including work as a homemaker, the value of separate property, the debts of the parties, and tax consequences. Marital misconduct is generally not a factor in dividing assets, even though it can establish grounds. A 2024 amendment to § 1513 treats companion animals as a distinct category, directing the court to award a pet to one or both spouses based on the animal's well-being and to allocate responsibility for veterinary expenses. The court may also impose a lien on assigned property to secure alimony. If retirement accounts are in play, a qualified domestic relations order may be required to divide them.

Frequently Asked Questions
Do I need a lawyer to get divorced in Wilmington?
No, Delaware allows self-representation, and the New Castle County Family Court provides free instruction packets and Resource Center help at 500 N. King Street. However, contested custody or property disputes are difficult to handle alone. A Wilmington divorce lawyer charging $250 to $400 per hour adds value when significant assets, support, or parenting time are at stake.
What is the filing fee for divorce in New Castle County?
The filing fee is $175 as of March 2026, consisting of a $165 petition fee plus a $10 court security fee, payable to "Family Court" by cash, check, or money order. Low-income filers earning at or below 150% of the federal poverty level can request a waiver using Form 257P to proceed in forma pauperis.
How long must I be separated before divorcing in Delaware?
Delaware requires a six-month separation before the court signs a no-fault divorce decree, under 13 Del. C. § 1507. Separation can occur under the same roof if spouses keep separate bedrooms and abstain from relations. Filing on misconduct grounds such as adultery, abuse, or desertion removes the six-month separation requirement entirely.
Can I file for divorce in Wilmington if my spouse lives elsewhere?
Yes, you can file in New Castle County as long as either spouse has lived in Delaware for at least six months before filing, per 13 Del. C. § 1504. The residency requirement attaches to either party, so even if your spouse moved out of state, your continued Delaware residence allows the case to proceed at the King Street courthouse.
How does Delaware handle child custody for Wilmington families?
The New Castle County Family Court decides custody using eight best-interest factors under 13 Del. C. § 722, including each parent's wishes, the child's adjustment to home and school, and each parent's relationship with the child. Delaware prohibits gender-based preferences and recognizes both joint and sole legal custody under § 727.
Is Delaware a no-fault divorce state?
Yes, Delaware primarily grants no-fault divorces based on a marriage being irretrievably broken after a six-month separation. Fault grounds such as adultery, abuse, or desertion exist and can waive the separation requirement, but they rarely affect property division under 13 Del. C. § 1513, which excludes marital misconduct from the asset analysis.
Where do I park at the Wilmington courthouse?
Parking is available in the Leonard L. Williams Justice Center garage adjacent to the courthouse at 500 N. King Street. You can enter on Walnut Street on the left after crossing 4th Street, or on King Street. The building offers ramp entrances and automatic doors for accessibility.
How much does an uncontested divorce cost in Wilmington?
An uncontested no-fault divorce in Wilmington typically costs $1,500 to $3,500 in total legal fees plus the $175 court filing fee, as of March 2026. Many local firms offer flat-fee packages for amicable cases. Service of process adds $10 to $100, and certified copies of the decree cost $10 each.
