Participant Contributions vs. Employer Contributions
In 401(k) plans, both the employee (participant) and employer can contribute. Employee contributions are always fully vested. Employer contributions, however, may be subject to a vesting schedule. This is an important detail when calculating the marital portion to be awarded in the divorce.
- Vested Account Balance: This is what is available to divide. It’s critical to confirm how much of the employer’s contributions are vested as of the date of division.
- Forfeited Amounts: Any unvested funds may be forfeited back to the plan if the employee separates from employment before vesting.
Don’t assume that the balance shown on a statement is entirely divisible — get a breakdown of vested vs. unvested amounts to avoid overpromising a non-participant spouse benefits that legally don’t exist.
