Realm Succession Law

    • House Seniority
      • All titles are inherited by the oldest eligible member of the house.
  • Multiple Heirs
    • Confederate Partition
      • Titles on the same tier as your top-level titles will be created if you hold more than 50% of the de jure land of the title.
      • Your oldest child receives the primary title, the capital, and any higher de jure title associated with the capital.
      • Titles on the same level as the primary title are distributed as equally as possible to the other eligible children with priority to the oldest children with the fewest titles.
        • Children who inherit a title on the same level as the primary title gain independence.
      • All remaining titles on the levels below are distributed in the same manner.
        • Children who only inherit titles on lower levels than the primary title become vassals of the primary heir.
      • The last step is repeated until all titles on all levels are distributed

      • TItles that were distributed to Other Heirs are distributed between the Other Heirs applying the rules of partition.

Surviving Confederate Partition

  • Problem: You have 3 sons but only hold 2 duchy titles.
    • Your primary heir inherits the duchy your capital is located in.
    • Your second son inherits the other duchy, all de jure counties in that duchy, and gains independence.
    • Since your third son can’t inherit any duchy titles, he will receive county titles from the domain of your primary heir (becoming his vassal) until he is as equally situated as possible leaving the primary heir with a duchy title but little land, income, and levies.
  • Keeping your domain together is vital.
  • Siblings gaining independence with their own top-level titles will receive land which they barely control resulting in very few available troops and making the land easy to conquer to reunify the realm.
  • Try to hold as many top-level titles as you have children or try to meet the requirements for enough titles to be created upon inheritance.
    • Your primary heir gets a claim on the top-level title his siblings received during inheritance, allowing for a relatively simple reunification of the realm.
    • Your primary heir will not get claims on the titles of siblings who became his vassal during inheritance.
  • Try to hand sufficient titles outside of your domain over to your sons before inheritance in order to avoid them cannibalizing your domain. These titles will count toward their inheritance.
  • Disinherit some eligible children who won’t receive the necessary titles to save your domain.
    • This option is only available if you are the dynasty head.
  • Use hooks you have to on your children to imprison and subsequently execute them, receiving a Tyranny penalty.
