Factors for courts to consider[edit]
Factors that a court may consider when determining whether or not to pierce the corporate veil include the following:[44][1]
- Absence or inaccuracy of corporate records;
- Concealment or misrepresentation of members;
- Failure to maintain arm's length relationships with related entities;
- Failure to observe corporate formalities in terms of behavior and documentation;
- Intermingling of assets of the corporation and of the shareholder; (share of production facility and home)
- Manipulation of assets or liabilities to concentrate the assets or liabilities;
- Non-functioning corporate officers and/or directors;
- Significant undercapitalization of the business entity (capitalization requirements vary based on industry, location, and specific company circumstances); (don't have a production facility is a form of undercapitalization)
- Siphoning of corporate funds by the dominant shareholder(s);
- Treatment by an individual of the assets of corporation as his/her own;
- Was the corporation being used as a "façade" for dominant shareholder(s) personal dealings; alter ego theory; (LLC seems to be a facade of your home mushroom business)
