Crusader Kings III How to Deal with Partition

• Titles could be created only if they are of the same rank as the main title
• After that is done titles will be given to heirs one by one, starting with the highest one.
• The ultimate goal is making sure every heir has equal (or the closest to equal) amount of titles after the ruler dies.

Well, in three possible ways:

• The most obvious, if you had enough land to form several same ranked titles, you will loose some land and will have to reconquer it.
• There was not enough “big” titles for everyone and they took your holdings, where you have 100% of everything
• In the case of an empire. it adds an extra layer of kingdom-rank vassals, which adds an extra reduction

In general:

• Plan ahead. If you are having multiple spouses/concubines, make sure their age is roughly the same. Don’t take a younger one as an extra/replacement.
• Don’t postpone until all females involved are infertile or you get all the land you plan to get in this life or whatnot, start the process as soon as you have an extra heir.

Exact process:

1. If you are within a single main title, all you need to do is, at any moment in time, give each extra heir the same amount of counties you (plan to) have plus an extra one if you have more heirs than second-to-highest titles (for example you have 4 heirs, but your empire only has 2 de jure kingdoms), ideally in their own de jure duchy/kingdom, and all de jure titles up to the second highest (you have to create those). Optionally before handing out kingdoms you can also increase the amount of given counties by +1, land your main heir and transfer all the other vassals under them when you feel its time.
2. If you will be splitting, you have to do basically the same as above, but landing the main heir is no longer optional. This way you’ll have to quickly claim some very small realms

This here is an example of doing it properly. On succession i will retain all my personal holdings. No drops in levies or gold until the younger heirs own successions kick in.
