Frequently Asked Questions
How much does it cost to find a lost 401(k)?
Nothing if you do it yourself using the free resources above. Some pension-finding services charge fees (often 5-10% of recovered assets), but this is rarely necessary.
Can a 401(k) completely disappear?
No, the money exists somewhere. It may be with your old employer’s plan, transferred to an IRA, sent to state unclaimed property, or held by a plan administrator. It doesn’t vanish, but finding it may take effort.
What if I worked somewhere 20+ years ago?
Start with the National Registry and state unclaimed property databases. Even old accounts should be traceable. Companies keep records, and assets transfer according to regulations.
Is there a statute of limitations on claiming?
Generally no. Retirement funds remain yours regardless of time passed. However, the money may have been transferred multiple times, making it harder to trace.
