The English courts also upheld marriages by consent in territories not under British control but only if it had been impossible for the parties to marry according to the requirements of the local law. The late 1950s and early 1960s saw a spate of cases arising out of the Second World War, with marriages in prisoner-of-war camps in German-occupied Europe posing a particular problem for judges. (Some British civilians interned by the Japanese during the Second World War were held to be legally married after contracting marriages under circumstances where the formal requirements could not be met.) To this limited extent, English law does recognise what has become known as a "common-law marriage". English legal texts initially used the term to refer exclusively to "American" common-law marriages. Only in the 1960s did the term "common-law marriage" begin to be used in its contemporary sense to denote unmarried, cohabiting heterosexual relationships and not until the 1970s and 1980s did the term begin to lose its negative connotations. The use of the term is likely to have encouraged cohabiting couples to believe falsely that they enjoyed legal rights. By the end of the 1970s a myth had emerged that marrying made little difference to one’s legal rights, and this may have fuelled the subsequent increase in the number of couples living together and having children together outside marriage.
