Accessing a Facebook business account
If you have a Facebook Page you can no longer access, and you wish to retrieve it, they may ask for a Notarised copy of documents. First you should contact someone on Facebook and they will be able to determine what the best course of action will be. Being locked out of a business Facebook account can happen because the person that created the account reassigned someone as an Editor, and then removed themselves as the administrator. Then deleted their own Facebook page that firstly created the business account.
