Is it ok I took out a 401k loan without telling my spouse? I am moving out on June 1st. I have meager savings and live in an expensive west coast city. We have money in the joint account to pay the mortgage and monthly bills. She has her own separate checking account. I need money to live and don't want to run up my credit cards. I plan to live very pauper like.

Tonight my mom lectured me since my retirement is mostly community property. She's concerned for my legal well being. I intend on telling my STBX in a few weeks in mediation.. I don't think I need her permission. Am I wrong to take money out and not ask for permission? Aside from the moral question of my action did I make a divorce mistake?
