A common-law rule holding a spouse or parent liable to third parties who supply goods or services required for the sustenance, support, or healthcare of the dependent spouse or child. Liability arises directly from the marital or parental relationship and the unmet need rather than from any agency or contractual undertaking by the supporting party. The scope of necessaries is determined by the family's circumstances, including the dependent's actual requirements and the supporting party's ability to pay.
Darius Dixon stopped depositing his salary into the joint account and refused to pay household bills. His spouse Dorothy Daniels obtained emergency surgery and charged the hospital bill to a credit card. The hospital sued Darius for payment. Because the medical services qualified as necessaries that Dorothy required and Darius had the ability to pay, the court held Darius liable directly to the hospital under the doctrine.
Darrell Duncan redirected his income away from family expenses. His spouse enrolled their child in a specialized preschool and left the tuition unpaid. The school sued both spouses. Because the educational services met the child's developmental needs and the supporting spouse had sufficient resources, the court imposed liability on the non-purchasing spouse for the unpaid tuition as a necessary.

Derek Douglas withheld joint funds after his spouse left the workforce to care for their child. The spouse bought necessary clothing and groceries on credit. The creditor sued Derek for the charges. The court found the items were necessaries suited to the family's station and held Derek liable because the purchases addressed an unmet support obligation.
Dwight Dorsey refused to cover basic living costs despite having ample income. His spouse purchased furniture essential for the household on credit. The seller sued Dwight. The court determined the furniture qualified as a necessary given the family's circumstances and imposed liability on Dwight regardless of any agency relationship.
No. Liability attaches when the dependent purchases necessaries and the supporting spouse has the ability to pay, regardless of prior refusal. Courts focus on the existence of need and capacity rather than on any explicit prior denial.

Modern applications treat the obligation as mutual and gender-neutral. Either spouse may be held liable for necessaries supplied to the other when the statutory or common-law support duty is unmet.
Supporting sources
Yes. Partial payment of one category of necessaries does not automatically defeat liability for other unmet necessaries. The court examines whether the specific goods or services supplied addressed an actual, unmet need created by the supporting spouse's conduct.
Supporting sources
It can. When specialized educational services are reasonably necessary for the child's development and no adequate public alternative exists, courts have treated the expense as a necessary for which the supporting parent remains liable.
