When you press pick ambition sometimes you get an ambition to revoke a title. This is a great way to reorganize your empire, without having to get claims on the title or incurring tyranny. But I can't figure out what decides which titles can be revoked through amibition. Anyone got a clue? So far I've ruled out:
- Having a claim on the title.
- Ruler desiring title.
- Title was granted by ruler.
- Holder of title doing traitorous stuff.

The "Revoke the County of ___" plot only requires that a count level vassal hold more than one county (or that a duke holds a county outside of his duchy) and that you not be incapable or an imbecile. BUT meeting those requirements does not ensure that the plot will show up. There is also an apparently random element in which plots appear and that random element is affected by a number of personality traits and other factors. So a "Content" character is very unlikely to see this plot. And a "Kind" or "Slow" character is somewhat unlikely to see it. But an "Ambitious," "Decietful," "Envious" character who meets the basic requirements will almost certainly see it. The chances of it appearing are also affected by your opinion of the target. If you hate them (according to the game's calculation of your opinion) then it is more likely that you will have this plot available.
At least that is how I read the files. I'd welcome anyone who has more insight into this.
