Any shortcut to change household ownership

[Joachim47]

Due to a divorce I am left with the house and all related automation.
The amazon support has no solution other than keeping the account of my EX.
Without concern we initially used her amazon account jointly.

The problem is that I manage our divorce without help in 60 days but Amazon doesn't plan for this.
Any practical suggestion would be great.
Whenever I try to make a change to some base setting amazon requires owner permission and I get either stuck or have to answer questions from her to get approval.

if you still have access to the account, just de-register it and set it up again using your account.   there are no shortcuts.
