Employee vs. Employer Contributions
Many 401(k) plans, especially those sponsored by professional corporations, include both employee and employer contributions. While employee deferrals are typically 100% vested, employer contributions often follow a vesting schedule. If your divorce happens before full vesting, only the vested portion of the employer contributions will be available for division.
It’s important that your QDRO for the Lili Mirtorabi Dds Ms a Professional Corp. 401(k) Plan distinguishes between vested and unvested amounts and makes it clear whether the alternate payee will be entitled to future vesting post-divorce (usually they are not).
