1. Employee vs. Employer Contributions
Most 401(k) plans like the 20/20 Research, Inc.. 401(k) Plan include both employee elective deferrals and employer matching contributions. A typical division in divorce applies to the full balance earned during the marriage, but employer contributions may follow a vesting schedule. That means unvested amounts may be off-limits to the alternate payee at the time of division.
Make sure to verify which portions are fully vested and clarify in the QDRO what is to be divided—only vested funds or the full marital share including future vesting.
