Crusader Kings 2 Thread III: Keeping Up With The Karlings

[Avilan the Grey]

Couple of controls and mechanics questions;

1) How do I inspect the laws of my lesser holdings?
2) Do you have any tips for getting people to accept my chosen candidate in elective sucession?
3) How do people check how much territory they'd need to found a kingdom/empire?
4) Do you have any tips for getting people to come to my court? I've tried bribey and matrilinial marriage, but the former is expensive early game and nobody will accept the latter.

Partial answer:
2) Make them like you. It is easier to get a heir selected the higher Prestige you have and the more the Dukes like you.
