A conjugal family is a nuclear unit made up of a married couple and their offspring (by birth or adoption), as well as a couple who are not yet legally married or who are minors. Conjugal implies a marriage-like relationship. Family ties are voluntary and based on emotional attachments rather than rigorous duties and obligations, and the family relationship is mostly inward-focused.
