Employee vs. Employer Contributions
Most 401(k) accounts contain two kinds of contributions: employee contributions (money the employee elected to defer from income), and employer contributions (often in the form of a match or profit-sharing). A QDRO can divide all vested amounts, but it’s essential to separate what’s fully vested and what isn’t at the date of division (usually the date of separation or divorce judgment).
Unvested employer contributions may not be divided unless they become vested in the future. QDROs for this plan should clarify whether unvested amounts are included if they later vest, or excluded entirely.
