Let me clarify this just a bit for you, Imsoold.
A parent/legal guardian can share an account with a minor child. This can be either a Battle.net account with multiple WoW licenses attached or a Battle.net account with one WoW license attached.
In the case where more than one WoW license is attached to the Battle.net account – both the parent and child can play at the same time, just not on the same WoW license. When logging into the game a dropdown menu will appear prompting you to select which account you wish to play. Parent and child would select the appropriate account at this point.
If there is only a single WoW license, only one party (parent or child) could play the account at that time. For example, if the parent is currently playing the game and the child attempts to log in, the parent will be disconnected.
I hope this helps to clear up some confusion.
