Will the chapter 13 trustee know if I cash out 401k?

Yes, the Chapter 13 trustee will likely be aware if you cash out your 401(k). During your bankruptcy proceedings, you are required to disclose all financial transactions and assets, including any withdrawals from retirement accounts. Cashing out your 401(k) could impact your repayment plan and may need to be reported, as it could be viewed as an attempt to hide assets. It's best to consult with your bankruptcy attorney to understand the implications fully.
