A common-law rule that imposes liability on one spouse for essential goods and services purchased by the other spouse. The rule applies when the purchasing spouse lacks sufficient funds and the items qualify as necessaries such as food, clothing, or medical care. Liability turns on the circumstances of the parties, including the need of one spouse and the ability of the other to pay.

Scott diverted firm profits away from the joint account, leaving Jared without funds for household expenses. Jared charged groceries, clothing, and therapy sessions for their child on a credit card.

Lydia McGuire petitioned for support after her husband refused to cover household repairs, furniture, and a new automobile. The court examined the couple's circumstances and required the husband to pay for those items. The decision rested on the husband's ability to pay and Lydia's demonstrated need for basic maintenance.
Miguel resigned his teaching position at Sean's request to care for their child and had no income. Sean deposited only his base salary into the joint account and refused to pay household or child expenses. Green Education sued both spouses for unpaid preschool tuition. The court considered whether the specialized program qualified as a necessary given the child's thriving progress and Sean's substantial earning capacity.
Sean withheld bonus income from the joint account while Miguel served as primary caregiver. Miguel petitioned for separate maintenance to cover living expenses and tuition. The court evaluated Miguel's need arising from career sacrifice against Sean's ability to pay. Liability for necessaries remained possible even without a pending separation action.
Necessaries include food, clothing, medical care, and similar essential expenses required for the supported spouse's sustenance and health. Courts assess whether an item meets this standard based on the parties' circumstances rather than an abstract list. Educational expenses for a child may qualify when they address documented needs that public alternatives cannot meet.

In some states a spouse may seek payments for necessaries at any time without seeking other relief. The rule focuses on the existence of unmet need and the other spouse's ability to pay. Courts may still decline to intervene when spouses continue to live together and no formal dissolution proceeding has begun.

The rule imposes liability regardless of actual agency authority between the spouses. A spouse who purchases necessaries binds the other spouse directly under the support obligation. Restatement commentary clarifies that this liability does not rest on true agency principles and cannot be controlled or terminated like an agent's power.

A non-emancipated minor who remains entitled to parental support may not be held liable for items that parents could provide. Courts refuse to treat housing or similar expenses as necessaries when the minor has a realistic option of receiving support from parents. The doctrine therefore does not automatically impose contract liability on such a minor.
