There are a handful of successful, high profile businesses started and run by couples, but investors reportedly shy away from start-ups founded by husband-wife teams.

Why? Interpersonal troubles can get in the way of building a business, VC Jonathan Tower explained in Fortune.

Whether this bias is entirely fair or not, the hesitance of investors to entangle themselves in other people's marriages reflects a sobering reality for couples thinking of going in to business together--maintaining your marriage and your business at the same time is often difficult. So how do you increase your odds of success?

That's a question that the Young Entrepreneur Council recently put to a number of founders, asking them what questions couples need to discuss before they pull the trigger on starting a business together. The experienced entrepreneurs came up with an extensive and thought-provoking list of ten questions, including:

Is our marriage more important than business? "If yes, then you need to make sure you both completely understand your roles and responsibilities in the office and in the home. Men may have a tendency to 'be the boss' in the office but that kind of attitude in the kitchen may result in a skillet to the forehead.

If you're bootstrapping, you may not have the luxury of an outside office right away, but consider where it falls in the roadmap," says Allie Siarto, Director of Analytics at Loudpixel.

Can we commit to occasional separation? "Business partners who are romantically involved with one another need to have a life outside of each other. Being in a relationship with someone doesn't mean you have to spend every waking hour with each other, especially in stressful situations. Make sure you set guidelines and have some time away from one another to let your relationship recharge," says Matt Wilson, co-founder of
