I don't have a verifiable answer for you.
But I don't think the QDRO is the issue.
A QDRO is only a court order instructing the custodian of the account to split the account between the two parties.
If the divorce decree mandates the split then the divorce decree can be enforced indefinitely.
In fact, if the account is your account, then you might have been the one with the obligation of filing the QDRO.
Consult an attorney.
