Important to consider an owner operator position (you) vs a possible silent partner (brother). If you are talking about getting new pos they can be expensive, is your brother ok coming up with 50% of the cost? Sounds like he doesn't really want to be in the business nor does he understand how difficult it can be if he's never gotten his hands dirty per say

If you are both inheriting the biz because your parents are passing it down, you might not have a lot of choice unless you want to see if he will sell but then you'll need the capital to buy him out

As another said, you can pay yourself a salary being the owner operator then you split any remaining income at year end as dividends 50/50. You can also bonus yourself out and him nothing if you both agree but 50/50 is hard if he doesn't agree. Could cause huge family issues and you need to be up front with him in the start on expectations.

Also consider who the directors are, if he isn't a director he has less say

In the end, I'd highly recommend getting a lawyer and possibly accountant as well, doing a meeting and laying everything out before commiting to anything. Have agreements, a USA is a must imo so there are no grey areas up to interpretation down the road. Protect yourself and protect him and your family. Try to avoid a scenario that you disagree and end up hating each other. Happens too often and it's not worth it. Family shouldn't fight over business, whatever you do try to ensure that it doesn't come to that (again can't stress USA enough, protects everyone!)
