Which succession law applies to king/duke/count titles held by an emperor? I found this answer that says the emperor title is separate from the duchy/kingdom, but the answer does not elaborate.
(Obviously, the emperor title is inherited based on the succession laws of the empire.)
Edit: I'm looking for an explanation of the general rules that are applied, not how to find the succession law in force for a specific title at a specific instant in time.
Edit 2: As I understand, when your character holds multiple titles, the succession law of your primary title usually "supersedes" the succession laws of other titles. For example
- If you hold 1 king title, or your highest title is count or duke, the succession law of your primary title applies to all of your titles.
- If you hold multiple king titles (and no emperor title), each king title has its own succession law. (see this answer for more)
- What if you hold an emperor title and no king titles?
- What if you hold an emperor title and 1 king title?
- What if you hold an emperor title and multiple king titles?
Best Answer
Open up your character window, and hover your mouse over your titles. An infobox should now appear, showing you the name of the title, the succession law and the line of succession.
I do not know a way to change the laws other than the one for your primary title, however. :/
EDIT:
Ok, I think I understand now. I believe it the core of the answer is whether or not a title is a de jure vassal to one of your greater titles. The succession law of a title will always be determined by the greatest title you hold in that "realm". If you have titles in other "realms", those will be determined separately.
PS: I know my use of the word 'realm' may be a bit different from the one used in game, but I could not find one that fit. What I mean by "realm", is a collection of titles which are de jure connected under one greater title which you control. I hope my intentions comes across despite this.
