In medieval Europe, in canon law, a betrothal could be formed by the exchange of vows in the future tense ("I will take you as my wife/husband," instead of "I take you as my wife/husband"), but sexual intercourse consummated the vows, making a binding marriage rather than a betrothal. Although these betrothals could be concluded with only the vows spoken by the couple, they had legal implications: Richard III of England had his older brother's children declared illegitimate on the grounds their father had been betrothed to another woman when he married their mother.[citation needed]
