If you have a bad credit/banking history and have been flagged for bouncing checks etc. by Chex you’re just going to have her from an LLC individually without you and get her to put everything in her name, if she’s willing to do this. If your name is on the account anywhere you may still have problems.
If this happens you need to be aware that she will be in complete control of the cash flowing into and out of the account and she will also be liable tax wise for the profits (if any). If the business, and current financial risk is tiny, this is possibly something you can attend to later re adding yourself if the business flourishes.
