Employee and Employer Contributions
401(k) plans typically have both employee and employer contributions. The employee’s contributions are usually 100% vested immediately, but employer contributions may be subject to a vesting schedule. A QDRO must clearly outline how contributions are divided:
- Clarify the split of employee contributions, typically based on marital coverture (the time period of the marriage during plan participation)
- Address partially vested employer contributions—unvested amounts are often forfeited when the marriage ends or the participant leaves the company
If the participant leaves the company before reaching full vesting, the non-participant spouse may only receive a fraction of the employer-match portion. Ignoring these rules can result in QDROs being rejected or unnecessary benefits being awarded.
