Personal Guarantee??

What is up with a Personal Guarantee? I got approval for my business on my own credit and assets and now, right before we began my Adventures in Cleaning..the company is insisting that both me and my spouse sign this agreement.

The problem is that my spouse and I separate our assets...always have. I know that this is unusual for a marriage but for my husband and I, this has worked great for the last eight years we have been married. I want this business more than I can say. In fact, I have began dreaming about it (LOL) but, to place my spouse assets (whatever they might be) in danger if I fail (which I firmly believe that I will not) at this business would be unfair and not right to him.

I guess I am wondering is Personal Guarantee's the norm when one spouse has been approved on their own creditworthiness. Maybe someone in cyberspace can chime in and let me know. Thanks, in advance.
