1. Employee vs. Employer Contributions
With 401(k) plans, both the employee and the employer can contribute. In a divorce, the QDRO can cover the full account or just the marital portion. Generally, that’s everything earned from the marriage start date to the date of separation or divorce. The alternate payee may receive a percentage or dollar amount of that marital portion.
Employer contributions may be subject to vesting. If the employee isn’t fully vested in those contributions, they might not be available. The QDRO should address how to handle any unvested amounts. One common approach: exclude unvested employer amounts from the division or include a forfeiture provision if they later vest.
