Employee and Employer Contributions
Dividing a 401(k) typically involves splitting the account as of a specific date (usually the date of divorce or separation). It’s important to understand:
- Employee contributions are always 100% vested.
- Employer contributions may be subject to a vesting schedule. Only the vested portion can be awarded to an ex-spouse.
If your former spouse is not fully vested in the employer contributions at the time of division, those unvested amounts will not transfer and may be forfeited according to plan rules. That’s why timing is important in QDRO drafting.
