We require personal guarantors for commercial debt to submit and sign a personal financial statement. That has a blurb about authorizing us to pull credit. Plus it's the "intent to lend/do business" rule that allows us to pull credit. We don't report guarantors to credit bureaus, even after they go south, I think we are too busy trying to work it out to remember that. However, I think there is a code to report a contingent liability on the CB if you really want to force the issue.
One more caveat, The personal fiancial statement should be addressed to your bank ( not have another banks name or logo on it) That makes it stronger if you take it into court and gives you that much more authority to pull the CB.
Luck is the collision of opportunity and preparation.
