1. Employee and Employer Contribution Splits
Most 401(k) accounts include both:
- Employee deferrals —These are fully the participant’s property and typically split by date of marriage or another cut-off date.
- Employer contributions —Often subject to a vesting schedule. If the participant is not fully vested, a portion of the balance may be forfeited when the employment ends.
In your QDRO, it’s essential to specify whether the alternate payee is entitled to only vested balances or some share of unvested amounts that may later vest.
