Hello, looking for some guidance on who can sign 401(k) plan documents, specifically in this case the initial adoption agreement & the initial consent/resolution. This is a new (and first) 401(k) plan for the business. My wife and I own/operate an S Corporation, but due to the rules and regulations of medical corporations in California, I am not allowed to be an officer or shareholder of the S Corp. She is technically the sole shareholder and the sole officer of the corporation. Our 401(k) TPA told me that a simple board of directors resolution giving me signing authority is sufficient, but I can't seem to find any legal info to back that up. I'm thinking of just having her sign documents for sake of simplicity (even though I will doing all the day to day work). Any advice or information is much appreciated. Thanks...
