Residency requirement:
Either you or your spouse must have lived in Delaware (or been stationed in the state as a member of the U.S. armed forces) continuously for at least six months immediately before filing the divorce petition (13 Del.C. §1504(a)). There is no additional county-level residency requirement — you simply file in the county where either spouse lives.
Filing fee:
$155–$175
Waiting period:
Delaware uses the Melson Formula (also called the Delaware Child Support Formula), found in Family Court Civil Rules 500–510, to calculate child support. The formula considers both parents' incomes, each parent's basic self-support needs, the number of children, childcare and healthcare costs, and the number of overnights the child spends with each parent. It is a rebuttable presumption, meaning the court may deviate from the formula amount if applying it would be inequitable.

Delaware law explicitly prohibits gender-based custody presumptions, meaning mothers and fathers have equal legal standing in all custody proceedings. Under 13 Del.C. §722, courts determine custody using eight statutory best-interest factors rather than favoring either parent based on sex. The filing fee for custody petitions in Delaware is $100 ($90 base plus $10 security assessment), and mothers seeking custody must file in the county where the child resides. Uncontested custody matters typically resolve in 2-4 months, while contested cases may extend to 6-18 months depending on complexity.

Understanding Delaware's Gender-Neutral Custody Framework

Delaware courts are statutorily prohibited from presuming that either parent is better suited for custody based on sex. 13 Del.C. §722(a) states that the court shall not presume that a parent, because of his or her sex, is better qualified than the other parent to act as a joint or sole legal custodian. This means mothers rights custody Delaware proceedings focus exclusively on the child's welfare rather than outdated assumptions about parental roles.

The elimination of maternal preference dates to legislative reforms ensuring constitutional equal protection compliance. Courts now evaluate both parents using identical criteria, examining factors such as each parent's involvement in the child's daily life, ability to provide stable housing, and willingness to support the child's relationship with the other parent. A mother seeking primary custody must demonstrate how her proposed arrangement serves the child's best interests rather than relying on her status as the mother.

Parents are designated as joint natural custodians under Delaware law, which means neither parent begins with a legal advantage. When parents separate, either parent may petition the Family Court for a custody determination. The petition initiates a process where both parties present evidence regarding the eight statutory best-interest factors, and the court renders a decision based on the totality of circumstances.

The Eight Best-Interest Factors Under 13 Del.C. §722

Delaware Family Court judges must evaluate eight specific factors when determining custody arrangements, giving each factor appropriate weight based on the circumstances of each case. Understanding these factors helps mothers prepare compelling evidence for their custody petitions.

Factor 1: Parental Wishes

The court considers each parent's preference regarding custody and residential arrangements. A mother's articulated plan for the child's care, education, and daily routine carries significant weight. Courts expect parents to present realistic, child-focused proposals rather than demands motivated by conflict with the other parent.

Factor 2: Child's Wishes

Delaware has no specific age when a child's preference becomes controlling, but courts routinely consider the wishes of children aged 12 and older. Judges may conduct in-chambers interviews with children to assess their preferences. The child's stated preference is one factor among eight, meaning courts can and do rule contrary to a child's wishes when other factors indicate a different arrangement serves the child's welfare.

Factor 3: Relationships and Interactions

Courts examine the child's relationship with parents, grandparents, siblings, and other household members who significantly affect the child's life. A mother who demonstrates strong, nurturing bonds with the child and facilitates positive relationships with extended family members positions herself favorably under this factor.

Factor 4: Adjustment to Home, School, and Community

Stability receives substantial consideration in Delaware custody determinations. Judges evaluate how well the child has adjusted to their current living situation, school environment, and community connections. Mothers seeking to maintain the status quo often have an advantage under this factor, while those seeking to relocate must demonstrate how the move benefits the child.

Factor 5: Mental and Physical Health

The mental and physical health of all individuals involved, including both parents and the child, is a statutory factor. Courts may order psychological evaluations in contested cases. A parent's health condition affects custody only to the extent it impacts their ability to care for the child; courts cannot discriminate based on disability absent evidence of harm to the child.

Factor 6: Compliance with Parental Duties

Under 13 Del.C. §701, parents have specific rights and responsibilities regarding their children. Courts examine each parent's past and present compliance with these duties, including financial support, involvement in education, attendance at medical appointments, and participation in daily caregiving. Documentation of a mother's consistent involvement in these areas strengthens her custody position.

Factor 7: Evidence of Domestic Violence

Domestic violence triggers special considerations under Chapter 7A of Title 13. Courts must consider evidence of domestic violence as a mandatory factor, even when the violence did not occur in the child's presence. This factor receives heightened scrutiny and can substantially affect custody outcomes.

Factor 8: Criminal History

The criminal history of any party or other resident of a household, including guilty pleas and pleas of no contest, constitutes the eighth statutory factor. Courts assess whether criminal conduct poses any risk to the child's safety or wellbeing.

Domestic Violence Protections for Mothers

Delaware provides robust statutory protections for domestic violence survivors seeking custody. Under 13 Del.C. §705A, a rebuttable presumption exists that no perpetrator of domestic violence shall be awarded sole or joint custody, and that no child shall primarily reside with a domestic violence perpetrator. This presumption shifts the burden to the accused parent to prove they should receive custody despite their history.

The presumption against custody for domestic violence perpetrators can only be overcome if the perpetrator demonstrates all of the following: successful completion of a specialized domestic violence intervention program, completion of substance abuse counseling if deemed appropriate by the court, and proof that awarding custody serves the child's best interests. The court must make specific written findings when placing a child primarily with a parent who has committed domestic violence.

Mothers who have experienced domestic violence receive additional procedural protections. Family Court mediation is prohibited in custody proceedings where one party has been found to have committed domestic violence against the other, unless the victim is represented by counsel and specifically requests mediation. This protection ensures survivors are not forced into negotiation sessions with their abusers.

When both parents have perpetrated domestic violence, the case must be referred to the Division of Family Services for investigation. The court then considers which parent was the primary aggressor in the household, recognizing that victims sometimes use defensive violence against their abusers.

Types of Custody Available in Delaware

Delaware distinguishes between legal custody and physical custody, and each type can be awarded as sole or joint custody. Understanding these distinctions helps mothers determine which arrangement best serves their family's needs.

Legal Custody

Legal custody refers to decision-making authority over major aspects of the child's life, including education, medical treatment, and religious upbringing. Joint legal custody means both parents share these decisions, while sole legal custody grants one parent exclusive authority. Even when one parent has sole legal custody, the other parent retains the right to receive information about the child's school progress, medical treatment, and activities.

Physical Custody

Physical custody, also called residential custody, determines where the child lives. The primary residential parent is the parent with whom the child spends the majority of time. Joint physical custody involves the child spending significant time with both parents, though not necessarily equal time. Courts establish specific visitation schedules or parenting plans that detail the residential arrangement.

Comparison of Custody Arrangements

Custody TypeDecision-MakingResidenceBest For
Joint Legal/Joint PhysicalShared major decisionsSignificant time with both parentsCooperative co-parents in proximity
Joint Legal/Sole PhysicalShared major decisionsPrimarily with one parentParents who communicate well but live apart
Sole Legal/Sole PhysicalOne parent decidesPrimarily with one parentHigh-conflict situations or safety concerns
Sole Legal/Joint PhysicalOne parent decidesSignificant time with both parentsRare; typically when one parent is uninvolved

Filing for Custody in Delaware

Mothers seeking custody in Delaware must file a Petition for Custody (Form 450) with the Family Court in the county where the child resides. The $100 filing fee includes $90 for the petition and $10 for court security. Fee waivers are available through an Affidavit in Support of Application to Proceed In Forma Pauperis for parents with income at or below 150% of the federal poverty level, approximately $23,895 for a single-person household in 2026.

Both parents must complete the Custody, Visitation and Guardianship Disclosure Report (Form 364) before attending mediation. This form provides the court with essential information about each parent's living situation, employment, and proposed custody arrangement.

Delaware Family Court requires mandatory mediation in all custody proceedings unless domestic violence exceptions apply. At mediation, a court-employed mediator assists parents in reaching agreement. If mediation succeeds, the mediator prepares a consent order for judicial approval. If mediation fails, the case proceeds to a contested hearing where a judge will determine custody.

Custody Jurisdiction: The UCCJEA

Delaware courts have jurisdiction over custody matters only when Delaware qualifies as the child's home state under the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA). The child must have lived in Delaware with a parent for at least six consecutive months immediately before filing. For children under six months old, Delaware must be the child's birth state.

This jurisdictional requirement prevents parents from forum shopping by moving to a new state to obtain a more favorable custody outcome. Mothers who have recently moved to Delaware may need to wait until the six-month residency period is satisfied, or may need to pursue custody in the child's prior home state.

Custody Modification and Relocation

Delaware recognizes that circumstances change and allows custody modifications under specific conditions. Under 13 Del.C. §729, the timing of a modification request affects the legal standard applied.

If a mother files for modification within two years of the most recent custody order, she must prove that continuing the current arrangement may endanger the child's physical health or significantly impair the child's emotional development. This heightened standard promotes stability by limiting frequent custody changes.

If the modification request comes more than two years after the prior order, courts apply a more flexible standard, weighing potential harm from modification against the advantages the modification would provide to the child.

Relocation Rules

When a parent seeks to relocate with a child for 60 days or more, court approval is required if the move significantly affects the current custody arrangement. This applies to both out-of-state relocations and in-state moves that would substantially impact parenting time.

A custodial parent must provide 60 days written notice before relocating. The court evaluates relocation requests using several factors: the nature and quality of the child's relationships with both parents, the child's developmental needs, feasibility of maintaining the non-relocating parent's relationship through visitation, the child's preference (considering age and maturity), and whether the relocation would improve quality of life for the relocating parent and child.

Upon filing a divorce petition involving children, an automatic preliminary injunction prohibits both parents from removing children residing in Delaware without the other parent's written consent or court permission under 13 Del.C. §1509.

Parenting Education Requirements

Delaware requires both parents in custody cases to complete a certified parenting education course. The course typically runs 6-8 hours with fees capped at approximately $100 per parent. Certificates of completion must be submitted to the court within 180 days of filing, or the petition may be dismissed.

This requirement applies to all parents, regardless of whether the custody matter is contested or uncontested. Courts view parenting education as essential preparation for co-parenting, teaching communication strategies, conflict resolution, and child development principles.

Timeline Expectations for Custody Cases

Case TypeTypical DurationKey Factors
Uncontested with Agreement2-4 monthsBoth parents agree; minimal court involvement
Mediated Settlement3-6 monthsParents reach agreement through mediation
Contested Hearing6-12 monthsTrial required; depends on court schedule
Complex Contested12-18 monthsCustody evaluations, expert witnesses, appeals

Mothers seeking custody should prepare for these timeframes while understanding that every case is unique. Court backlogs, scheduling conflicts, and the complexity of contested issues all affect how quickly a case moves through the system.

Information Rights for Non-Custodial Parents

Even when one parent receives sole legal custody, Delaware law protects the other parent's right to information about the child. Each parent has the statutory right to receive, upon request, material information concerning the child's school progress, medical treatment, school activities, conferences, religious events, and other activities. Both parents retain the right to attend these activities and to contact the child by phone and mail.

These information rights ensure that mothers rights custody Delaware arrangements do not entirely exclude non-custodial fathers from the child's life, and similarly protect non-custodial mothers' ongoing involvement when fathers receive primary custody.

Property Division and Child Support Considerations

While custody and property division are separate legal issues, they often interconnect in divorce cases involving children. Delaware follows equitable distribution principles under 13 Del.C. §1513, meaning courts divide marital property fairly (though not necessarily equally) based on multiple factors including the length of marriage, each spouse's economic circumstances, and contributions to marital property.

Child support calculations in Delaware consider the custody arrangement, with the residential percentage affecting support obligations. Mothers who receive primary physical custody typically receive child support from the non-custodial parent, calculated using Delaware's income shares model.

Frequently Asked Questions

Do mothers have an advantage in Delaware custody cases?

Delaware law explicitly prohibits courts from favoring either parent based on sex. Under 13 Del.C. §722(a), judges cannot presume mothers are better custodians. Custody decisions rest entirely on the eight best-interest factors, meaning both parents begin on equal legal footing regardless of gender.

How much does it cost to file for custody in Delaware?

The filing fee for a custody petition in Delaware is $100 total, comprising a $90 base fee plus a $10 court security assessment. Fee waivers are available for parents with income at or below 150% of the federal poverty level (approximately $23,895 for a single person in 2026). As of May 2026. Verify with your local clerk.

Can I get custody if I was not married to my child's father?

Unmarried mothers have the same custody rights as married mothers in Delaware. However, paternity must be legally established before courts can address custody with the father. Once paternity is confirmed, both parents are joint natural custodians, and either may file for a custody determination using the standard best-interest analysis.

What is the residency requirement for filing custody in Delaware?

Under the UCCJEA, the child must have lived in Delaware with a parent for at least six consecutive months immediately before filing for Delaware courts to have jurisdiction. For infants under six months old, Delaware must be the child's birth state. There is no separate residency requirement for the parent filing.

How does domestic violence affect custody decisions?

Domestic violence triggers a rebuttable presumption against awarding custody to the perpetrator under 13 Del.C. §705A. The accused parent must complete domestic violence intervention programs and prove custody serves the child's best interests to overcome this presumption. Courts must consider domestic violence evidence even when it did not occur in the child's presence.

Can I move out of state with my child?

Relocating with a child requires either the other parent's written consent or court approval. Under 13 Del.C. §729, you must provide 60 days notice before relocating. Courts evaluate whether the move serves the child's best interests, considering factors such as the child's relationship with both parents and whether meaningful visitation remains feasible.

At what age can my child choose which parent to live with?

Delaware has no specific age when a child's preference becomes controlling. Courts may consider the wishes of children aged 12 and older, but this is just one of eight statutory factors. A judge may conduct an in-chambers interview with the child but retains full authority to order arrangements contrary to the child's stated preference when other factors indicate a different outcome serves the child's welfare.

How long does a custody case take in Delaware?

Uncontested custody cases typically resolve in 2-4 months. Cases settled through mediation generally take 3-6 months. Contested cases requiring a trial often extend to 6-12 months, while complex contested matters involving custody evaluations or expert witnesses may take 12-18 months or longer.

What happens if the other parent violates the custody order?

Custody order violations can be addressed through a motion for contempt filed with the Family Court. The court may impose sanctions including modification of the custody arrangement, attorney fee awards, or in serious cases, jail time. Document all violations carefully, as courts require specific evidence of non-compliance.

Can grandparents get custody or visitation rights in Delaware?

Grandparents may petition for visitation rights under limited circumstances, typically when the parents' marriage has been disrupted through divorce, separation, or death. Grandparent custody is possible when both parents are unfit or have abandoned the child. Courts apply the best-interest standard to grandparent petitions while respecting parental rights.
