Serfs had to ask for permission to get married by the Lord
True.
In many feudal societies, serfs were required to obtain permission from their lord to marry.

However, generally speaking, serfs were considered property of the lord and their personal matters, including marriage, were subject to his authority.
AnswerThe nobility. They were slaves. AnswerThe serfs were not slaves. They were not free, as they were bound to the land they lived on, but they could not be bought or sold, and they could not be taken off the land by the lord any more than they could leave it without his permission. Doubtless they sometimes did work as servants, but usually they were agricultural, and they were much more likely to take work doing simple labor than as servants. There were reeves, who organized and supervised the serfs on manors, and who acted as representatives for the lords to the serfs and for the serfs to the lords. The reeves, however, were also serfs, and were often elected by the serfs annually. There are links below.
