Delaware Divorce: Fast Facts

How to File for Divorce in Delaware

Delaware is a no-fault divorce state — you file on the ground that your marriage is "irretrievably broken" and do not need to prove wrongdoing. One key requirement sets Delaware apart: you and your spouse must be legally separated for 6 months before the court can enter a final divorce decree. You can file your petition earlier, but the court will not finalize the divorce until that period is complete. If your separation is already behind you, an uncontested case can close quickly after filing.

1. Confirm Residency and Begin Your Separation — At least one spouse must have lived in Delaware for 6 continuous months before filing. At the same time, confirm that you and your spouse are legally separated or begin your separation period. Under Delaware law, spouses can be considered legally separated even while living in the same home — provided they occupy separate bedrooms and do not have sexual relations.
2. Prepare and File the Petition for Divorce/Annulment — File the Petition for Divorce/Annulment with the Family Court in the county where either you or your spouse lives — New Castle (Wilmington), Kent (Dover), or Sussex (Georgetown). Pay the filing fee of approximately $165 plus a $10 court security fee. The Delaware Family Court provides free standardized instruction packets at courthouse Resource Centers and online at courts.delaware.gov. If you cannot afford the fee, file an Affidavit in Support of Application to Proceed In Forma Pauperis to request a waiver.
3. Serve Your Spouse (or Obtain an Affidavit of Appearance) — After filing, the court clerk will typically forward the summons and petition to the county sheriff for service on your spouse. Your spouse then has 20 days to file an Answer. In cooperative cases where both spouses agree, your spouse can instead complete and file an "Affidavit of Appearance" — the Delaware equivalent of a waiver of formal service — which signals their participation and typically speeds the case along.
4. Complete the Parent Education Course (If You Have Minor Children) — If you or your spouse has minor children, both parties must complete a court-certified Parent Education Course — at least 4 hours of instruction on the impact of divorce on children. Certificates of completion must be filed with the court before the divorce can be finalized. Enroll early; failing to complete this requirement is a common cause of delay. View approved courses at courts.delaware.gov.
5. Satisfy the 6-Month Separation Period and Exchange Financial Disclosures — The court will not enter a final divorce decree until 6 months of legal separation have elapsed. Use this period to negotiate your Marital Settlement Agreement (MSA) covering property division, alimony, custody, and child support. If you are requesting ancillary relief — property division, alimony, or support — you must also complete and file the Ancillary Financial Disclosure Report with the court.
6. Request a Final Hearing or Proceed Without One — Once the 6-month separation period is complete and all filings are in order, you choose whether to request a final hearing. In uncontested cases, Delaware allows you to ask the court to decide "on the papers" by filing a "Request to Proceed Without Hearing" along with an "Affidavit in Support of Request to Proceed Without Hearing." If a hearing is held, the petitioner typically must appear; the respondent is not required to attend. The judge then issues the Decree of Divorce.

Fault grounds bypass the separation period: If you are filing on misconduct grounds — such as physical, mental, or psychological abuse, adultery, or desertion — the 6-month separation period does not apply. However, you must present sufficient evidence of that misconduct to the court before a divorce will be granted on that basis. Most Delaware divorces are filed on no-fault grounds. See Delaware Family Court's official divorce guide.

Delaware Divorce Laws: Grounds, Residency, and the Separation Requirement

Delaware is a no-fault divorce state — the only recognized ground is that the marriage is "irretrievably broken" and reconciliation is improbable. However, the underlying reasons for the breakdown (such as misconduct or incompatibility) can be relevant when establishing that the marriage has in fact broken down. Delaware also retains fault-based misconduct grounds — including abuse, adultery, and desertion — which allow filing without the required 6-month separation period.

Delaware's "Same-House Separation" Rule — What It Means for You

Many couples assume they must live in separate homes to be considered legally separated in Delaware. That is not the case. Delaware law defines legal separation as occupying separate bedrooms and having no sexual relations — even if both spouses remain under the same roof. This is particularly important for couples who cannot afford two households while the divorce is pending.

What counts as legal separation in Delaware:

• Occupying separate bedrooms
• No sexual relations between spouses
• Can occur in the same home or separate residences

Why the start date matters:

• The 6-month clock starts from the date separation begins, not the filing date
• Filing early can allow you to complete discovery and negotiation during the waiting period
• If separation is complete before filing, the case can finalize weeks after filing is accepted

For the full text of Delaware divorce law, see Title 13, Chapter 15 of the Delaware Code. For court self-help resources and instruction packets, visit courts.delaware.gov/family/divorce.

Property Division in Delaware: Equitable Distribution

Delaware is an equitable distribution state. When dividing marital property, the court aims for a fair result — not automatically an equal one. A 50/50 split is possible but not required. The court weighs multiple statutory factors to determine what is just under the circumstances of each case. Marital misconduct does not affect property division in Delaware.

Key factors Delaware courts weigh when dividing marital property:

• Each spouse's contribution to the acquisition, preservation, or appreciation of marital property — including contributions as a homemaker
• The value of each spouse's separate property
• The economic circumstances of each spouse at the time of division, including who will serve as the primary custodian of any children
• The length of the marriage, and the age and health of both spouses
• Tax consequences of the proposed division
• Whether either spouse has wasted, dissipated, or concealed marital assets

Delaware's companion animal rule: Delaware was among the first states to formally address pet ownership in divorce. If a pet was acquired during the marriage, it is treated as marital property — but the court considers factors beyond simple ownership, including each party's ability to care for the animal, the attachment between the pet and each spouse, and the pet's overall welfare. Either party may later petition for sole ownership if circumstances substantially change.

Spouses can resolve all property matters through a written Marital Settlement Agreement at any time.

Alimony in Delaware

Alimony in Delaware is not automatic — it is available only to a "dependent party" who lacks sufficient property or earning capacity to meet their reasonable needs after divorce. Courts weigh multiple statutory factors and award support in an amount and duration they deem just. Marital misconduct does not bar or reduce alimony eligibility in Delaware. The statute places a hard cap on duration for marriages under 20 years — but for marriages of 20 years or longer, there is no time limit on eligibility.

Factors Delaware courts consider when awarding alimony:

• The financial resources of the party seeking alimony — including any marital property awarded — and their ability to meet their own reasonable needs
• The time and expense required to gain sufficient education or training to find appropriate employment
• The standard of living established during the marriage
• The duration of the marriage and the age, health, and station in life of both parties
• Any financial or other contribution either party made to the other's education, training, career, or earning capacity during the marriage
• The paying spouse's ability to meet their own needs while paying alimony; and whether either party sacrificed economic or career opportunities during the marriage

Delaware's 50% duration cap and the 20-year rule: For marriages lasting less than 20 years, alimony eligibility cannot exceed 50% of the length of the marriage. A 10-year marriage, for example, could yield at most 5 years of alimony eligibility. For marriages of 20 years or longer, there is no statutory time limit — the court retains discretion to award alimony for as long as it deems just. In either case, alimony automatically terminates upon the death of either party, the recipient's remarriage, or the recipient's cohabitation with a partner they hold themselves out as a couple with.

Delaware provides an official spousal support calculator at courts.delaware.gov/family/supportcalculator. For a general guide on how support is estimated, see our alimony calculator guide. For cases with significant income disparity, a Certified Divorce Financial Analyst can help you model scenarios before negotiating your settlement.

Child Custody and Support in Delaware

Delaware Family Court determines custody based on the best interests of the child. Neither parent has a presumptive custody advantage based on gender. Parents who agree on a parenting plan can present their arrangement to the court for approval; if they cannot agree, the court decides. Child support is calculated using the Delaware Melson Formula — a distinctive multi-step method unique to Delaware that factors in each parent's basic self-support needs before calculating the child's share.

Key factors Delaware courts weigh in custody determinations:

• The wishes of the child's parents regarding custody and any history of primary caregiving
• The child's adjustment to their current home, school, and community
• The mental and physical health of all individuals involved, including any history of domestic violence or substance abuse
• Each parent's ability to provide a stable, loving environment and to support the child's relationship with the other parent
• The child's own preferences, if the child is of sufficient age and maturity to express a reasoned opinion

Delaware uses the Melson Formula — not the income shares model: Delaware is one of only three states that uses the Melson Formula (also called the Delaware Child Support Formula) to calculate child support. Unlike the income shares model used by most states, the Melson Formula first reserves a basic self-support allowance for each parent before calculating what remains for the child's needs. It also accounts for childcare costs, healthcare expenses, and the number of overnights the child spends with each parent. The result is a rebuttable presumption — the court may deviate from it if applying the formula would be inequitable. Use the official calculator at courts.delaware.gov/family/supportcalculator.

How Much Does a Divorce Cost in Delaware?

A Delaware divorce can cost as little as $175 in court fees for a straightforward uncontested case — or $15,000–$30,000+ per spouse in a fully contested divorce with attorneys and trial. The biggest cost driver is disagreement: every issue that must be resolved by a judge rather than negotiated by the spouses adds attorney hours, court appearances, and delay. Delaware's mandatory 6-month separation period means even the fastest possible divorce spans at least half a year.

Additional Delaware-specific costs to budget for:

• Sheriff service fees — typically $10–$100; the county sheriff handles service of process by default in Delaware unless the respondent files an Affidavit of Appearance
• Parent education course — up to $100 per parent for cases involving minor children; mandatory before the court can finalize the divorce
• Ancillary relief filing fees — additional fees apply for each ancillary request filed alongside the petition (property division, alimony, child support, custody, visitation); verify current amounts with your county Family Court clerk
• QDRO drafting — $500–$1,500 per retirement plan; required to divide 401(k), pension, or other employer-sponsored retirement accounts; see our QDRO guide
• Certified copies of the decree — a small per-copy fee applies; obtain 3–5 certified copies for name change, beneficiary updates, mortgage refinancing, and records

If cost is a concern, read our guide on how to get divorced with little or no money. Fee waivers are available for qualifying low-income filers — file an Affidavit in Support of Application to Proceed In Forma Pauperis with your petition, or visit the Delaware Courts legal assistance page for free legal help resources.

Uncontested vs. Contested Divorce in Delaware

Delaware recognizes both contested and uncontested divorce. In an uncontested case, both parties agree on all issues — property, support, custody, and parenting — and may ask the court to finalize the divorce without a hearing at all. In a contested case, one or more issues must be decided by a judge, typically resulting in a longer and more expensive process. All cases are heard in Delaware Family Court, which operates in all three counties.

Proceed without a hearing in uncontested cases: Delaware allows uncontested divorce petitioners to file a "Request to Proceed Without Hearing" together with an "Affidavit in Support of Request to Proceed Without Hearing." If the court approves, the judge reviews the submitted papers and issues the Decree of Divorce without either party ever appearing in a courtroom. You must notify the court of your preference within 20 days of the Notice of Trial-Readiness. If a hearing is held, the petitioner typically must attend; the respondent is not required to appear.

If you and your spouse are close to agreement but stuck on specific issues, Hello Divorce mediation services can help bridge the gap at a fraction of litigation costs. Mediation is especially effective for property division, alimony, and parenting plan disputes.

Legal Separation in Delaware

Delaware does not have a formal court-ordered "legal separation" status the way some states do — there is no separate petition you file to become legally separated. Instead, separation in Delaware is defined by conduct: you and your spouse occupy separate bedrooms and have no sexual relations. That separation, whenever it begins, starts the 6-month clock that must run before your divorce can be finalized. Understanding this distinction is important for timing your filing correctly.

Document your separation start date: Because the 6-month period runs from when separation actually begins — not from the filing date — establishing a clear, documented start date matters. A dated text message, email, or written notice to your spouse stating the intent to separate can serve as evidence if the date is ever disputed. This is particularly important when both spouses remain in the same home, where the start of separation may be less obvious to outside observers. If you are also requesting property division, the date of separation can affect what gets counted as marital property.

To understand your options before filing, read our guide: Legal Separation vs. Divorce. For settlement agreement guidance applicable during the separation period, see our settlement agreement checklist.

Delaware Divorce Forms and Paperwork

Delaware Family Court provides free standardized instruction packets — available at each county courthouse Resource Center and online — that include all required forms, instructions, and sample documents for both contested and uncontested divorces. The forms below are the core documents for a typical Delaware divorce. Additional forms apply depending on which ancillary requests (property, alimony, custody, support) you include with your petition.

Changing Your Name After Divorce in Delaware

In Delaware, a name change after divorce is not automatic — you must request it as part of your divorce petition. If approved, the judge will include the name restoration in the final Decree of Divorce. Once you have your certified Decree, follow this sequence to update all records.

1. Request the name change in your Petition — Include a prayer for name restoration in your Petition for Divorce/Annulment at the time of filing. Delaware's name change form and instructions are available at courts.delaware.gov/help/changename. Obtain at least 3–5 certified copies of your Decree when it is issued — you will need them for every institution below.
2. Social Security Administration — Update your SSA record first using your certified Decree and photo ID. Visit your local SSA office, submit Form SS-5 by mail, or complete online at ssa.gov. You need an updated SSA card before the Delaware DMV will update your driver's license.
3. Delaware DMV (Driver's License) — Visit a Delaware DMV office with your updated SSA card, certified Decree, and proof of Delaware residency. If you need a Real ID-compliant license, bring additional documentation per DMV requirements.
4. U.S. Passport — Submit the appropriate DS form with your certified Decree. Use DS-5504 if your passport was issued less than 1 year ago (no fee); DS-82 if issued more than 1 year ago (fee required); or DS-11 for a first-time application or passport issued more than 15 years ago.
5. Financial accounts, employer HR, and insurance — Contact each institution individually with a certified copy of your Decree. Update bank accounts, retirement beneficiaries, health insurance, life insurance, and employer payroll records.

Frequently Asked Questions: Divorce in Delaware

How long does a divorce take in Delaware?

The minimum is approximately 6 months — driven entirely by Delaware's mandatory separation period, which must elapse before a divorce decree can be entered. If you and your spouse have already been separated for 6 months before filing, an uncontested case can be finalized in a matter of weeks after the paperwork is submitted and approved. If you file before completing separation, the court will simply wait until the 6-month period is satisfied. Contested divorces involving property, alimony, custody, or support disputes typically take 12 to 18 months or longer, depending on the complexity of the issues and court scheduling.

Does Delaware require separation before divorce?

Yes — for a no-fault divorce in Delaware, you and your spouse must be legally separated for at least 6 months before the court can enter a final decree. Separation does not require living in separate homes: under Delaware law, you and your spouse can be considered legally separated while still living under the same roof, provided you occupy separate bedrooms and do not have sexual relations. You can file your divorce petition before the 6-month period is complete — the court will wait. The one exception is fault-based divorce: if you are filing on misconduct grounds such as abuse, adultery, or desertion, the 6-month separation requirement does not apply, but you must present evidence of the misconduct to the court.

Is Delaware a 50/50 divorce state?

No. Delaware is an equitable distribution state, which means marital property is divided fairly — but not necessarily equally. A 50/50 split is possible but not guaranteed. The court weighs multiple factors including each spouse's economic circumstances, contributions to the marriage, the length of the marriage, each party's separate property, and the needs of any children. Marital misconduct does not affect property division in Delaware. All property acquired during the marriage is presumed to be marital property regardless of how it is titled, while property owned before the marriage, third-party gifts (properly documented), and inheritances are generally treated as separate property not subject to division.

Do I have to go to court for a divorce in Delaware?

Not necessarily. In an uncontested Delaware divorce, you can ask the court to decide your case "on the papers" — without either party ever appearing in a courtroom. To do this, file a "Request to Proceed Without Hearing" together with an "Affidavit in Support of Request to Proceed Without Hearing" within 20 days of the Notice of Trial-Readiness. If the court approves, the judge reviews your submitted documents and issues the Decree of Divorce without a hearing. If a hearing is held in your case, the petitioner typically must attend, but the respondent is not required to appear. In contested cases, a hearing before a Family Court judge or commissioner is required.

How does alimony work in Delaware?

Alimony in Delaware is available only to a dependent party — someone who lacks sufficient property or earning capacity to meet their own reasonable needs after divorce and is unable to support themselves through appropriate employment. The court awards alimony in an amount and for a duration it considers just, without regard to marital misconduct. For marriages lasting less than 20 years, alimony eligibility is capped at 50% of the marriage's length — so a 12-year marriage could yield at most 6 years of alimony. For marriages of 20 years or longer, there is no time limit on eligibility, though the court still weighs all relevant factors. Alimony automatically ends upon the death of either party, the recipient's remarriage, or the recipient's cohabitation with a partner they present themselves as a couple with.

How is child support calculated in Delaware?

Delaware uses the Melson Formula — one of only three states to do so — which is a multi-step calculation unique to Delaware. Unlike most states, the Melson Formula first reserves a basic self-support allowance for each parent before calculating what is available for the child's needs. It then factors in each parent's net income, the number of children, childcare and healthcare costs, and the number of overnights the child spends with each parent. The result is a rebuttable presumptive amount — the court may deviate if applying the formula would be inequitable in a specific case. Use Delaware's official child support calculator at courts.delaware.gov/family/supportcalculator to estimate your obligation. For a general guide to child support calculators, see our child support calculator guide.

Can I get divorced in Delaware without a lawyer?

Yes. Many Delaware residents complete uncontested divorces without an attorney using the free instruction packets available at every Family Court courthouse Resource Center and online at courts.delaware.gov. The process is particularly manageable when both spouses agree on all terms — property, alimony, custody, and support — and no contested hearing is required. Online services like Hello Divorce provide guided form preparation, a completed Marital Settlement Agreement, and access to attorneys and mediators by the hour when you need specific help, without requiring a full retainer or paying for services you don't need. Delaware also provides free legal assistance resources at courts.delaware.gov/help/legalassistance.

What financial disclosures are required in a Delaware divorce?

If you are requesting any form of ancillary relief — property division, alimony, child support, custody, or visitation — Delaware requires you to complete and file an Ancillary Financial Disclosure Report (Form 465) with the court. This form discloses each party's income, assets, debts, and expenses, and is the financial foundation on which property and support decisions are made. The petitioner must file this report within 30 days after entry of the divorce decree if ancillary relief is requested. Incomplete or inaccurate financial disclosures are a common cause of delays and disputed judgments in Delaware family court proceedings. If you are not requesting any ancillary relief — for example, if both parties have already agreed to all financial terms in a written Marital Settlement Agreement — this form may not be required.
