You can sue your brother if he pocketed the proceeds or otherwise diverted them to himself, his family, a business he owns, etc. If the home was willed or otherwise left to you as well as him, you had a 1/2 interest in it: you were entitled to 1/2 the proceeds (after paying any necessary costs, such as to maintain it until selling, the cost of the sale and marketing, and paying off any liens or mortgages). You could not have stopped him selling if he wanted to--when there are two or more owners and at least one wants to sell, he can bring a legal action to get a court order forceing a sale (commonly called an action "for partition"), so the main focus here is not on whether he sold it, but on the fact tht you did not get anything. Consult with an attorney about this situation: it is apt to be procedurally complex, but fundamentally, if you inherited the home as well as he, you were entitled to your share of the money, and by a lawsuit, you can force him to pay it.
