Add co-owner

[Aaronj1]

I need to know how to add a co-owner to my Square account

As far as I know you only can have one “owner” 

My sister and I both own our coffee shops but only my name is on the account. Which has proved to be difficult because my last name as also changed and that cannot be altered. 

Is there a reason you want both? Both my sister and I still can have full access to everything!
