Employee vs. Employer Contributions
When dividing a 401(k), it’s essential to distinguish between employee contributions and employer contributions. Employee contributions are always 100% vested, meaning they belong fully to the employee at the time of contribution. Employer contributions, however, may be subject to a vesting schedule.
A typical QDRO may award a percentage of the account as of a certain date, such as the date of separation or divorce filing. However, if unvested employer funds are included in that balance, the alternate payee (the ex-spouse) could inadvertently receive a share of funds the participant doesn’t actually own yet. That’s why careful drafting is not just helpful—it’s required.
