Employee and Employer Contributions
In most 401(k) plans, the employee makes pre-tax or Roth contributions, and the employer may make matching or profit-sharing contributions. In divorce, the QDRO must specify exactly which contributions are being divided. Are you splitting just the employee contributions? All of them? As of the date of separation or another date?
Many spouses assume “50/50” means half of everything. But without a clear QDRO, the plan administrator won’t know how to split the account—or worse, may reject the order entirely.
