Can you let your sibling manage a business for you?

[Henrywrites]

Well, if my sibling have knowledge of the business and it's something that is good enough for me to trust him or her to manage the business, I don't see any reason why I should stand in his or her way of managing the business for me especially when I am not available to take care of things.

I think it is all about being able to trust your siblings to handle the business. As long as they are trustworthy and have the knowledge of the business, there is no reason you shouldn't let them handle the business.
