I sure hope this was an example from the web site and not you.
1. When you leave a company, rollover the money from the company 401K plan to your private 401K plan immediatly (first thing, right off the bat, the day after you leave the company). As long as it sits in a corporate 401K plan, they have control over your money (not you).
2. Did the new company remove some of the money from the plan that the old company had included as a “match” to your contribution? If so, then all I can say is see #1 above.
Otherwise, what the heck are you talking about? You quit the company. No company will match your contributions to a 401K plan made after you quit the company.
I’m not talking about the matching of contributions after leaving the company. We are being told we are not entitled to the matched contributions that were made while he was with the company even though he was fully vested while he was with that company.
