How do I train my daughter to become Lady of the House?

Last night my daughter (11) called for a family meeting. In the meeting, she stated that she felt as though her father ( my husband) has been disobedient to her and her rules ( he didn't want to take her to Build A Bear a couple of days ago, and last month called in sick to work without her permission) is because he is confused with her role and my role in the house. She went on to say that since she will be 12 soon, and will be starting her mensuration, that she should be the ' Lady of the House', and that that title will be taken from me since I am nothing more than trash to her. My husband and I both agreed, since my angel is perfect and whatever she thinks is right is. She will move her bed ( twin size) into our room and sleep there ( in her bed, my husband will sleep in our queen sized bed) while I sleep in our ex- daughters room. I will be aloud to sleep with my husband once a week.

How do I train and prepare her for this? She wants this to go into effect once she turns 12 in March. I know she will do a much better job then I ever could, as she is much more sophisticated and intelligent then I will ever be. My husband agrees and feels that the roles will be much clearer if we do this. My main role will be to cook, clean, and serve her after I have trained her.
