Employee vs. Employer Contributions
With a 401(k) profit sharing plan, there are typically two types of contributions: those made by the employee (through salary deferrals), and those made by the employer (often discretionary). Under divorce law, both types can be divisible depending on the date of marriage and date of separation. A QDRO must clearly state how each component is to be split.
Some employers may make contributions annually or on a discretionary basis, and unvested portions may not be eligible for division. This brings us to the next issue—vesting schedules.
