Age of majority (England)

The age of majority in England is 18, having been reduced from 21 by the Family Law Reform Act 1969. At that age persons are considered as adults and acquire the legal capacity to enter into legally binding contracts (thus to hold a credit card and take out a loan), to vote in elections, to buy tobacco and cigarettes and have a tattoo. Below that age persons are considered in law to be "infants" and colloquially to be "children".

History.
During the mediaeval era and the era of feudalism, in England the age of majority for males was 21 and for females 14 if married and 16 if single. The attainment of such an age was usually referred to as being "of full age". Thus wardship for males ended at the age of 21, on the obtaining by the ward of a "proof of age" writ, issued after a Proof of age inquisition had obtained evidence from a jury of witnesses. Until that time a ward could be forced to marry a person of the warder's choosing, often his own child, and the resultant progeny would inherit the property formerly subject to the wardship at their father's death, usually regulated by the marriage settlement.
