My question involves bankruptcy in the state of: Michigan

My question has to do with funding a Health Savings Account during BK. My employer is switching to an employee funded health plan, and will allow us to use a HSA. I realize that during a Chapter 13 I cannot invest in my 401 K, however are there any rules dictating that I cant max out on my HSA? This would reduce my net salary as well, helping to get me closer to the Median income.

Does anyone know if the trustee would have an issue with a large monthly contribution?
