Full Text of Rule 507

Text sizeJump to: (a) (b)

(a) Available, Affordable, and Accessible Health Insurance. One or both parents shall be ordered to acquire private health insurance when it is available through employment, reasonable in cost, and accessible to the child. Whether health insurance available to a parent other than through employment is reasonable in cost and should be acquired or maintained will be determined on a case-by-case basis.
(1) Reasonable Cost. In the context of establishing or modifying a child support obligation health insurance is reasonable in cost if:
(i) The premium to cover both the parent and the parent's dependent children does not exceed ten percent (10%) of the parent's gross income; and
(ii) After inclusion of the insurance premium in the Formula, the parents' combined net income pursuant to Rule 502 is sufficient to provide all primary expenses exclusive of private school tuition.
(2) Continuing Duty to Acquire Insurance. If affordable coverage is not available at the time of the order or whenever coverage lapses, each parent shall be ordered to acquire coverage that becomes available if the cost to cover both the parent and the parent's dependent children does not exceed ten percent (10%) of the parent's gross income.
(3) Accessibility. Health insurance is accessible to a child if it covers medical services within a reasonable distance from the child's primary residence.
(4) Termination. Once a parent has been ordered to acquire or maintain a specific policy of insurance, the parent shall continue the coverage despite changes in cost or accessibility until further order of the Court or written consent of the opposing party, or the State of Delaware if the child is a Medicaid recipient.
(5) Specialized Coverage. Whether either parent is required to acquire or maintain dental, vision, or other specialized coverage shall be determined on a case-by-case basis. A National Medical Support Notice or medical support attachment shall not include specialized coverage unless expressly ordered.
(b) Cash Medical Support. Every new or modified order for current support entered on or after January 1, 2015, shall impose an obligation of cash medical support on each parent who is a party to the petition.
(1) Cash medical support shall include all healthcare expenses not reimbursed by insurance, and incurred for the children for whom the order is entered. Such expenses include, but are not limited to, medical, dental, orthodontic, vision, and psychological counseling costs incurred on behalf of each child.
(2) Each parent's obligation for cash medical support shall be determined by multiplying the amount of unreimbursed healthcare expenses by the parent's primary share percentage as defined in Rule 503(a) but rounded to a multiple of 10% as herein described. As needed, percentages greater than 50% shall round down to the next 10% interval; percentages less than 50% shall round up. Other than a child with only one known living parent, the percentage shall be neither greater than 90%, nor less than 10%. If the support recipient is a nonparent and the child has only one known living parent, then the cash medical support percentage is 100%. The cash medical support percentage for inmate obligations imposed pursuant to Rule 506(c) shall be 50%.
(3) An action for contribution to or reimbursement for a medical expense for a child may be brought at any time after the medical expense is incurred. However, any right of reimbursement will be presumed to have been waived unless a petition for reimbursement is filed with the Court by December 31 of the second year following the date the expense was incurred. This presumption may be rebutted for good cause shown.
(4) Incurred. For purposes of this rule (including orders entered before 2015 that assigned the first $350 of healthcare expenses to the child support recipient), “incurred” shall be the date the medical healthcare service was provided, except that in the event a parent contracts to pay orthodontic or other long-term treatment services over a period of time the date each periodic payment is due under the contract shall be deemed to be the date the expense was “incurred.”

Plain-English Summary

Insurance. One or both parents are ordered to acquire private health insurance where it is available through employment, reasonable in cost, and accessible to the child. Insurance available other than through employment is judged case by case.

Reasonable in cost means two things together: the premium covering the parent and their dependent children does not exceed 10% of that parent's gross income, and after the premium goes into the Formula the parents' combined net income still covers all primary expenses other than private school tuition. The second condition is the one that matters — insurance is not affordable if buying it means the children's basic needs go unmet.

A continuing duty. Where affordable coverage is unavailable at the time of the order, or coverage lapses, each parent is ordered to obtain coverage that becomes available within the same 10% limit. The obligation waits for the opportunity rather than expiring with the order.

Accessible means the policy covers medical services within a reasonable distance of the child's primary residence. A cheap plan whose doctors are an hour away is not coverage.

Staying put. Once ordered to acquire or maintain a specific policy, a parent continues it despite changes in cost or accessibility until the court orders otherwise, the other party consents in writing, or the State consents where the child is a Medicaid recipient. Dental, vision and other specialised coverage is decided case by case, and a medical support attachment does not include specialised coverage unless expressly ordered.

Cash medical support. Every new or modified current support order entered on or after January 1, 2015 imposes cash medical support on each parent — their share of healthcare expenses that insurance does not reimburse, including medical, dental, orthodontic, vision and psychological counselling costs.

The share. Multiply the unreimbursed expense by the parent's primary share percentage, rounded to a multiple of 10%: above 50% round down to the next interval, below 50% round up. It is never more than 90% nor less than 10% — except where the recipient is a nonparent and the child has only one known living parent, when it is 100%. For obligations imposed on an incarcerated parent it is 50%.

Rounding to tens is a small mercy. Parents split a dentist's bill many times over the years, and a percentage they can do in their heads is a percentage they will not come back to court over.

Claiming it back. An action for contribution or reimbursement may be brought any time after the expense is incurred — but the right is presumed waived unless a petition is filed by December 31 of the second year following the date the expense was incurred, and that presumption may be rebutted for good cause. An expense is incurred on the date the service was provided, except that where a parent contracts to pay for orthodontics or other long-term treatment over time, each periodic payment is incurred when it falls due.
