I think this should be a fairly straightforward thing to resolve, it will just take time. The only issue is that you own a kin house--that holds up transfers for whatever reason. Probably to save people from losing a lot of money by accidentally transferring a character they forgot was the purchaser of the kin house. Or maybe some assume the house will transfer with them.

Either way, yeah, I think it would just take a manual kin disbanding by a GM. And that GM actually following through, of course.
