Only the Page Admin have the rights to change the page owner. There are no specific information on how to change the ownership in that page however you can transfer the page ownership from one account to another.
To check your role on the page Click Settings at the top of your Page > Page Roles in the left column.
If you want to transfer your Facebook PAGE to another person or account (who must have a Facebook profile) you need to ensure that they are your Facebook Friend or have Liked your PAGE.
Go to your PAGE to manage the Admins > click Edit Page > Admin Roles. And start typing name so it appears and click on the profile to place it in the box, and then click Save Changes.
If the name method doesn’t work, try entering their email address in the box as that often works.
And if that doesn’t work try below, as sometimes there is a glitch doing it the “correct” way.
Click > Edit Page > and RIGHT-CLICK on “See Banned Users” and “Open in New Tab / Window“. When the page arrives change “Banned” to “People who like this”, then find the person there on the list and click “Make Admin”. ALSO if there are any other BLANK boxes below, then click the “x” next to them and remove them, then do the “Save” and add your password, which is the Admin’s own personal Facebook login password. You might have to try it several times to make it work.
If you make that new Admin a “Manager” they will now have as much control of your PAGE as yourself. (If you are asked for a password use your own personal Facebook login password).
If you want to relinquish your Admin status, just click “Remove Admin” against your name, and if you wish to leave the PAGE completely, just view the PAGE and click “Unlike“.
