1. Employee vs. Employer Contributions
In most 401(k) plans, there are two types of contributions: those made by the employee and those made by the employer. When dividing the plan through a QDRO:
- Employee contributions (and investment growth) are usually considered marital property if they were made during the marriage.
- Employer contributions may be subject to a vesting schedule. Only vested amounts are divisible in divorce.
It’s important your QDRO excludes non-marital or unvested employer contributions, unless otherwise agreed in your divorce judgment.
