My wife and I have separate 401k's with Alerus (myself) and Fidelity (her). She recently left her employer and has no intent to return, and will probably be a stay-at-home mom for the foreseeable future. Can I roll her 401k into mine as a consolidation? The Alerus customer service rep said that isn't allowable by the IRS, but he didn't sound very confident, so can someone here clarify? Thanks.
