(from Ch. 76, par. 4)
If any person shall assume and exercise exclusive ownership over,
or take away, destroy, lessen in value, or otherwise injure or abuse any
property held in joint tenancy or tenancy in common, the party aggrieved
shall have his civil action for the injury in the same manner as he would
have if such joint tenancy or tenancy in common did not exist.
