Until now I thought it was just prestige, but I believe there is something related with legitimacy also...
I was married with Portugal with no heir.
England: 7 prestige and I do not his legitimacy, but they are in a regency.
Austria: 100 prestige and around 60 legitimacy.
The portuguese king died and the dinasty passed to be Lancaster and not Hapsburg.
Right now I have another case:
Austria: +76 prestige and 74 legitimac
Lithuania: Prestige +26
We are both married with Poland and if right now the king of Poland would die, Lithuania would get a PU
What is the criteria?
