1. Employee vs. Employer Contributions
You’ll need to consider whether your division includes just employee contributions, or employer contributions too. Many 401(k) plans include employer matches or profit sharing. However, these employer-funded portions might be subject to a vesting schedule. That means if the participant hasn’t met certain service requirements before the divorce date, some of those funds may be forfeited and not available for division.
It’s essential to request a breakdown of vested versus unvested balances as of the cutoff date for division (often the date of separation or divorce judgment). That way, your QDRO won’t inadvertently assign benefits that don’t exist due to vesting rules.
