Under Delaware law, extracurricular activity costs are not automatically included in basic child support calculations but can be added as extraordinary expenses and divided between parents based on their respective shares of Net Available Income. Delaware Family Court uses the Melson Formula under 13 Del.C. § 514, which allows courts to order additional payments beyond base support for activities such as sports, music lessons, summer camps, and club memberships. The typical cost-sharing arrangement allocates expenses proportionally—if Parent A earns 60% of combined income and Parent B earns 40%, they split activity costs 60/40. Courts consider whether activities were established before separation, serve the child's developmental needs, and fall within both parents' financial ability to pay.

How Delaware Treats Extracurricular Activity Costs in Child Support
Delaware Family Court treats extracurricular activity costs as extraordinary expenses that can be added to the base child support obligation under Family Court Civil Rules 506-508. The court may order one parent to pay an additional amount specifically designated for activities—for example, $2,000 per month in regular child support plus $500 for extracurricular activities. This approach ensures that children maintain access to enrichment activities regardless of which parent has primary custody.
Under Delaware's framework, extraordinary expenses include school supplies, textbooks, school trips, private lessons (music or academic tutoring), special clothing and equipment for sports or clubs, and organization membership fees. The court evaluates each expense category based on the child's established participation patterns, developmental benefits, and both parents' financial capacity. Unlike some states that require mutual parental consent for all activity expenses, Delaware courts can order cost-sharing even when parents disagree about specific activities.
Delaware's three-step Melson Formula first ensures each parent retains approximately $1,570 per month for self-support (110% of federal poverty level), then calculates primary support needs, and finally applies a Standard of Living Adjustment (SOLA) ranging from 12% for one child to 21% for three children. After determining the base support obligation, courts add extraordinary expenses and allocate them proportionally based on each parent's percentage of combined Net Available Income.
The Melson Formula and Activity Cost Allocation
Delaware is one of only three states (along with Hawaii and Montana) that uses the Melson Formula for child support calculations. Named after Delaware Family Court Judge Elwood F. Melson Jr. who developed it in the 1970s, this formula takes a more nuanced approach than standard Income Shares models by first protecting each parent's ability to meet basic needs before calculating support obligations. The formula is codified in Delaware Family Court Civil Rules 500 through 510 and operates as a rebuttable presumption under 13 Del.C. § 514.
The Melson Formula calculation for 2026 uses the formula ($410 per child + $370) for primary support, then applies SOLA percentages based on the number of children. After determining base support, the court adds extraordinary expenses including extracurricular activities. For a family with combined monthly Net Available Income of $8,000 where Parent A contributes $5,000 (62.5%) and Parent B contributes $3,000 (37.5%), extracurricular costs of $400 per month would be allocated $250 to Parent A and $150 to Parent B.
The numerical values in the Melson Formula are adjusted automatically in January of every odd-numbered year based on federal poverty guidelines. All monetary allowances were updated in February 2026 to reflect current economic conditions. The entire formula was scheduled for comprehensive review in 2026, which may result in updated guideline amounts and self-support thresholds.
Types of Extracurricular Expenses Delaware Courts Consider
Delaware Family Court recognizes multiple categories of extracurricular expenses that may be added to base child support obligations. Each category requires documentation of costs and evidence that the activity serves the child's developmental interests.
Sports and Athletic Activities
Sports involvement encompasses registration fees, equipment costs, uniform expenses, travel for competitions, and coaching fees. Delaware courts evaluate whether athletic participation was established before the parents' separation and whether continuing the activity serves the child's physical and social development. A child who played competitive soccer throughout elementary school would have stronger grounds for continued parental cost-sharing than a newly proposed activity.
Music, Art, and Academic Enrichment
Private lessons for music, art, or academic subjects (such as subject tutoring) qualify as extraordinary expenses under Delaware law. These costs include instructor fees, instrument rental or purchase, art supplies, and competition entry fees. Courts consider the child's demonstrated aptitude and commitment level when determining whether to order cost-sharing.
Camps and Seasonal Programs
Summer camps and seasonal programs represent significant expenses that Delaware courts may allocate between parents. However, to qualify for inclusion in child support calculations, childcare-related camp expenses must be work-related—meaning the parent needs the program to work, seek employment, or attend job training. Purely recreational camps may still be included as extraordinary expenses but face closer scrutiny regarding necessity.
Organization Memberships and Fees
Membership dues for organizations such as Boy Scouts, Girl Scouts, 4-H, religious youth groups, and similar activities qualify as extraordinary expenses. Courts also consider the costs of special group activities, field trips, and related participation fees. School-related activities including essential trips (such as museum visits) are generally included, though international travel for occasions like spring break may not necessarily qualify.
Legal Process for Establishing Activity Cost-Sharing
Delaware parents seeking court-ordered sharing of extracurricular activity costs must follow specific procedural steps through the Family Court system. The process differs depending on whether parents are establishing initial support orders or modifying existing arrangements.
Initial Child Support Orders
When establishing original child support during divorce proceedings, parents should document all current extracurricular activities with receipts, invoices, and registration records. The filing fee for divorce in Delaware is $165 plus a $10 court security fee, totaling $175 as of March 2026. Either spouse must have lived continuously in Delaware for at least six months immediately before filing under 13 Del.C. § 1504(a).
Parents complete Form 509 (the manual worksheet) with Form 509-I (instructions) or use the online calculator to determine base support. The worksheet includes sections for extraordinary expenses where extracurricular costs should be listed. Courts review these submissions and determine proportional allocation based on each parent's share of combined Net Available Income.
Modification Petitions
Under Family Court Rule 508, any petition for child support modification filed within two and one-half years of the last determination is subject to specific review criteria. New extracurricular activities, increased costs for existing activities, or changes in parental income may all justify modification. Parents must demonstrate that circumstances have materially changed since the original order.
The modification process requires providing documentation such as receipts, invoices, or statements showing consistent and substantial costs. Judges evaluate each parent's financial situation, the nature of the activity, and whether the activity was established before the initial support order. If both parents can afford the extra costs without undue burden, modification approval is more likely.
Shared Placement and Activity Expense Considerations
Delaware recognizes shared placement when a child spends at least 164 overnights per year with each parent. In shared placement situations, the child support formula adjusts to reflect reduced expenses for each household. However, extracurricular activity costs present unique considerations because activities occur regardless of which parent has custody on any given day.
Failure to contribute to shared incidental expenses including clothing, school supplies, and activities may result in denial of shared placement status for child support calculation purposes. This provision incentivizes both parents to participate in covering activity costs even when formal court orders do not specify exact amounts. Courts view cooperative expense-sharing as evidence of genuine shared parenting.
Regardless of where children are living, their continued participation in extracurricular activities should not be interrupted according to Delaware Family Court guidelines. The parent with whom the children are staying is responsible for providing transportation to activities scheduled during their contact time. Each parent must provide the other with notice of all extracurricular activities, including schedules and contact information for activity leaders.
Joint Legal Custody and Activity Decisions
Under 13 Del.C. § 727, parents with joint legal custody must both participate in major decisions about education, medical treatment, religious upbringing, and extracurricular activities. This statutory requirement means that neither parent can unilaterally enroll a child in expensive activities and then demand reimbursement from the other parent.
When parents share joint legal custody, the selection and funding of extracurricular activities requires cooperation. Judges scrutinize who is making critical decisions for the child when evaluating custody arrangements. Parents who share responsibilities regarding activity selection demonstrate stable household management. Conversely, a parent who makes unilateral decisions about costly activities may face resistance when seeking court-ordered reimbursement.
The parent with sole legal custody may select extracurricular activities without the other parent's consent but may still need to share costs proportionally if the activity qualifies as an extraordinary expense. Courts balance decision-making authority against financial fairness, ensuring that children benefit from appropriate enrichment activities while protecting non-custodial parents from unreasonable financial demands.
Creating Enforceable Activity-Sharing Agreements
Many Delaware parents include extracurricular activity provisions in their separation agreements to prevent disputes and reduce the need for formal court modification. These written agreements specifying activities and financial contributions can be incorporated into the child support order for enforcement purposes.
Effective activity-sharing agreements should specify categories of activities covered (sports, music, academic enrichment), maximum annual or per-activity spending limits, the approval process for new activities, payment timelines and methods, documentation requirements for reimbursement, and dispute resolution procedures. Clear provisions prevent conflicts when children develop new interests or existing activities become more expensive.
Parents can reach agreements outside of court to share extracurricular costs through mediation or direct negotiation. However, incorporating these agreements into formal court orders provides enforcement mechanisms if one parent fails to pay their share. Delaware Family Court can hold non-paying parents in contempt and order wage garnishment or other collection measures for unpaid extraordinary expenses included in support orders.
Financial Documentation Requirements
Delaware courts require thorough documentation when parents seek to establish or modify extracurricular expense allocations. Successful petitions include registration receipts, equipment purchase records, lesson payment confirmations, travel expense logs, and organization membership invoices.
Parents should maintain organized records throughout each calendar year showing activity-related expenses by category. Digital copies of receipts, credit card statements highlighting activity charges, and written communications about activity costs all support modification petitions. Courts evaluate whether claimed expenses are reasonable, verified, and consistent with the child's established activity patterns.
The Form 509 child support worksheet includes sections for documenting extraordinary expenses. Parents must list each expense category with monthly amounts. Courts verify submitted figures against supporting documentation and may request additional records if claimed expenses appear inconsistent with typical costs for similar activities.
When Courts Deviate from Standard Allocations
Delaware Family Court Civil Rules allow deviation from standard proportional allocations when applying the formula would be unjust or contrary to the child's best interest. Several factors may justify deviation in extracurricular activity cost-sharing cases.
Extraordinary medical expenses affecting a parent's ability to pay activity costs may support deviation. Similarly, extraordinary educational expenses such as private school tuition (when both parents agree or when it serves the child's best interests) may affect available resources for extracurricular activities. The child's own income or assets from employment, inheritance, or trust funds may also factor into deviation analysis.
Tax consequences of activity expenses, particularly when one parent claims child-related deductions, may justify adjusted allocations. Significant disparity in parents' living standards—where one parent enjoys substantial luxury while the other struggles financially—may support deviation from strict income-based proportions. Courts maintain broad discretion to ensure fair outcomes for both parents and children.
Relocation and Activity Continuity
Delaware law addresses extracurricular activity considerations when a custodial parent seeks to relocate. If relocation may result in changes to the child's school, travel time to activities, or otherwise adversely affect the child's best interest, the relocating parent must obtain written approval from the other parent or a court order before moving.
Courts evaluate how proposed relocations would affect established activity participation. A child competing at high levels in a particular sport or advancing in musical training may have compelling interests in remaining near current coaches, instructors, or teammates. Relocation petitions must address how the child's activity continuity would be maintained or what equivalent opportunities exist in the proposed new location.
Related travel expenses for visitation may factor into extracurricular cost allocations after relocation. If one parent relocates and the child continues activities near the original residence, transportation costs for activity participation during visitation may be shared between parents or allocated to the relocating parent who created the distance.
Frequently Asked Questions
Are extracurricular activities automatically included in Delaware child support?
No, Delaware's base child support calculation under the Melson Formula does not automatically include extracurricular activities. These costs are treated as extraordinary expenses that may be added to base support and divided proportionally based on each parent's share of Net Available Income. Parents must specifically request activity cost-sharing through the court or include provisions in their separation agreement.
How does Delaware divide extracurricular costs between parents?
Delaware allocates extracurricular expenses proportionally based on each parent's percentage of combined Net Available Income. If Parent A contributes 65% of combined income and Parent B contributes 35%, activity costs would typically be split 65/35. The court may deviate from this standard when circumstances warrant different allocation.
Can one parent enroll a child in expensive activities without the other parent's approval?
Parents with joint legal custody under 13 Del.C. § 727 must both participate in major decisions including extracurricular activities. Unilateral enrollment in expensive activities without consent may affect a parent's ability to recover costs from the other parent. The parent with sole legal custody has more discretion but should document decisions and costs carefully.
What expenses qualify as extraordinary extracurricular costs in Delaware?
Delaware courts recognize sports registration and equipment, private lessons (music, art, academic tutoring), summer camps, organization memberships (scouts, youth groups), school activity fees, competition entry fees, and related travel expenses. School supplies, textbooks, and essential field trips also qualify. Purely recreational international travel generally does not qualify.
How do I request modification of child support for new activities?
File a modification petition with Delaware Family Court demonstrating material change in circumstances. Provide documentation of activity costs including receipts, registration records, and proof of the child's participation. Under Rule 508, petitions filed within 2.5 years of the last determination require showing substantial changed circumstances. Filing fees apply.
What if my co-parent refuses to pay their share of activity costs?
If activity cost-sharing is included in your court order, file a contempt motion with Delaware Family Court. The court can enforce payment through wage garnishment, asset seizure, or other collection mechanisms. If costs are not yet in your order, you must petition for modification before seeking enforcement.
Does shared custody affect extracurricular expense allocation?
Shared placement (164+ overnights per year with each parent) adjusts base child support calculations but does not eliminate extracurricular cost-sharing obligations. Failure to contribute to shared incidental expenses including activities may result in denial of shared placement status for support purposes. Both parents remain responsible for proportional activity costs.
Can I get a fee waiver for filing modification petitions about activity costs?
Delaware Family Court waives the $165 filing fee for petitioners demonstrating financial hardship through an Application to Proceed In Forma Pauperis. Approval typically requires income at or below 150% of federal poverty level (approximately $23,895 for a single-person household in 2026). Submit an affidavit documenting income, assets, expenses, and dependents.
How do courts decide which activities are necessary for my child?
Delaware courts evaluate whether activities were established before separation, serve physical, social, or emotional development, align with the child's demonstrated interests and abilities, and fall within both parents' financial capacity. Activities the child participated in before divorce carry more weight than newly proposed expenses. Documentation of the child's commitment and progress supports inclusion.
What happens to extracurricular costs when child support ends?
Under 13 Del.C. § 501, child support including extraordinary expense obligations continues until age 18 or high school graduation (up to age 19). Once support obligations terminate, parents have no legal requirement to share activity costs unless they voluntarily agree. College extracurricular expenses are generally not covered by Delaware child support orders.
