Under Arizona law, a judgment creditor against you personally may get a charging order against your interest in the LLC. That charging order then makes the judgment creditor an assignee of your interest in the LLC. As an initial matter, that entitles the creditor to all distributions that you would receive from the LLC until the judgment is satisfied. Normally that is the sole remedy that the creditor would have collect for a personal debt from your LLC. But that would mean, of course, that you'd not be able to take out anything from the LLC for yourself until that judgment was paid.
However, there is one other possibility when the LLC is a single member LLC. Since the credtor becomes an assignee of your interest in the LLC and you are the only member of the LLC, you normally would have the sole power to determine who becomes a member of the LLC. As an assignee, the creditor may be able to then make itself a member of the LLC. See Arizona Revised Statutes (ARS) §§ 29-731 & 732 From there it might then be able to force the LLC to liquidate. That then would cause a distribution of all the assets of the LLC, which the creditor could then get as a result of the charging order. So it would take a few steps to get there, but there is that possibility of reaching the LLC assets to collect a personal judgment. There are ways to set up the LLC to prevent that possibility, and you'd want to see a business lawyer about that.
What are my options? If I start growing my company they will be able to take funds out as soon as they enter the business?
This is a common concern for many clients that operate small businesses. In Illinois, my first questions to business owners asks them the type of business to ascertain the level of risk they undertake. If you are concerned about a risk that has occurred already, then I believe you are to late to do anything about it. If you are working to clean up your operations, starting now with correct accounting and book keeping is a start. In Illinois there is no "bright line" test that will destroy your liability protection through the LLC. There are a multitude of factors that are considered. If you have a new wave of business, or are in a risky business environment then a new LLC would be helpful. the new LLC minght not be required but due to the case by case assessment utilized, the cost may be worthwhile. Discussing this with an attorney in Arizona would provide you direction. Good luck.*
There's no line at all when it comes to him being PERSONALLY sued for his PERSONAL debts. The LLC is an asset.
