They enjoyed NO legal rights that were not “subject” to “local custom” - local custom being whatever your local Knight Baron or King decided it was.
“feudalism describes a set of reciprocal legal and military obligations among the warrior nobility, revolving around the three key concepts of lords, vassals and fiefs”
A Baron owed legal and military obligations to his King - the King owed nothing to the serfs under said Baron.
As I said, and apparently have to repeat -
The idea that “real” separation of powers entails that Baron going to the King (or vice versa) and saying “Your son is out raping peasant women - please put a stop to it!” is delusional.
They didn't care - local custom was that the son of the Aristocracy could do whatever he wanted to the peasant women.
And cutting the guts of a peasant open to warm your hands in his entrails during a cold winter hunt was decidedly frowned upon.
Better get started writing up that hand drawn currency - because other than that I really don't see ANYTHING ELSE OF ANY VALUE coming from you deranged deluded anti-American delusion.
Contemplate the mangled bodies of your countrymen, and then say ‘what should be the reward of such sacrifices?’ Bid us and our posterity bow the knee, supplicate the friendship and plough, and sow, and reap, to glut the avarice of the men who have let loose on us the dogs of war to riot in our blood and hunt us from the face of the earth? If ye love wealth better than liberty, the tranquility of servitude than the animated contest of freedom, go from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains sit lightly upon you, and may posterity forget that you were our countrymen!
So again I say to you : GO from us in peace. We ask not your counsels or arms bootlicker.
local custom being whatever your local Knight Baron or King decided it was
That is not what "local custom" means.
the King owed nothing to the serfs under said Baron.
The King had obligation of military protection to the baron, who in turn owed it to his villeins and serfs.
And so on. You don't seem to know what you are talking about.
