Though people in the medieval period weren’t as conscious of litigation as we are today.
Oh yes they were! The medieval mindset was strikingly legalistic - even the plots of some of their romances turn on legal quibbles - and litigation was a constant preoccupation for a wide range of medieval society, verging on a national sport. Law was the one essential ‘paper’ subject of a nobleman’s education in the High Middle Ages, and the fact that Norman French survived for some time after it ceased to be not only a cradle-tongue but the everyday language of any rank of society including the royal court was partly due to its being the language of the law courts; both nobles and bourgeoisie needed to know it. After the Pleading in English Act of 1362 changed the language of court proceedings to English, the better-off peasantry were able to join in, and 15th-century sources show villagers suing and counter-suing each other with gusto. If medieval English had had Oxford commas, medieval Englishmen would certainly have quibbled about them in court.
