my 50% partner wants to dissolution our business and I don't want to

My brother and I are 50% owners of a 86 year family restaurant that was given to us by our parents.. He wants a dissolution because I won't agree to him taking money without working for it and he wrote himself a check for $10000 in December and a $5000 check to give to Mom, without an agreement from me or any vote on it at the corporate meeting. So he essentially stole the money. What rights do I have against him trying to dissolve the business without my agreeing to it
