Minimum Distribution Payable to Right Beneficiary - Checks Picked up by Wrong Beneficiary

[rocknrolls2]

Let's say an employer maintains a 401(k) plan for its employees. A participant retires and then starts receiving minmum distribution payments in connection with his/her attainment of age 70 1/2. The checks are payable to the individual who is the participant and bear the correct social security number. Unfortunately, the participant moved without informing his//her employer of the change of address. Therefore, the checks are still delivered to the same home address in the name of the participant at the same social security number. However, in the meantime, an individual with the same first and last name as the participant has begun cashing the checks although s/he has also been reporting the distributions on his/her tax return. The error has since been discovered and the individual who had cashed the checks is now willing to pay the amount back to the plan.

My question would be what should be done by the plan other than through the SCP program of simplying issuing the checks to the intended participant? I see no qualification issue on the part of the plan since it paid the checks to the correct SSN and to what it thought was the correct address. Similarly the participant should not be subject to the excise tax because the circumstances should make him/her eligible to satisfy the reasonable error test resulting in waiver of the tax. Does anyone see anytihing else here that I have not specifically mentioned?
