I assume that these are typically formed for pecuniary reasons.
But I've often heard that when Tatsuo Shimabuku formed Isshin-ryu he "followed tradition" by appealing to other (grand)masters for permission to form his art and their approval of him as a new head of system--that he felt he needed to do that to form a new style. The story is that he did a demo. for them and spoke with them and they conferred and in essence granted him the right/distinction of being a head of a system.
I haven't heard it of any other founder so I am a bit suspicious, but is there any such precedent? Whether or not it was true of Isshin-ryu is somewhat incidental.
