A dependant (British English) or dependent (American English) is a person who relies on another as a primary source of income. For example, a minor child, under the age of majority, is a dependant of his or her parent. However, a common-law husband or a wife who has been maintained by their partner may also be included in this definition. The existence of the dependant may enable the provider, such as a parent or guardian, to claim a deduction, for example in income tax calculations.
In the UK, a full-time student in higher education, and with an adult who depends upon them, may be eligible for an 'Adult Dependant's Grant' in addition to other student finance they may be in receipt of.
