Can The Plan Administrator Rely on Employee's Information?

[Guest hhacker]

Employee in DB plan, that is funded by life insurance policies, advised employer upon entry that his date of birth was in 1932. Premiums are paid and benefits calculated on that basis. Employee dies. After his death, his driver's license shows his date of birth as 1923. Insurance companies reduce payouts. Beneficiaries claim entitlement to benefits based on 1923 date of birth. Can Plan Administrator rely on the date of birth given to him (1932). There is no independent verification of date of birth and several other documents show various dates of birth between 1923 and 1935.
