1. Employee vs. Employer Contributions
401(k) plans generally consist of contributions from the employee and often matching or profit-sharing contributions from the employer. In the Washington Brick & Terra Cotta Company Profit Sharing & 401(k) Plan, both may be present.
Your QDRO must clearly state how much of each type of contribution is to be divided—and from what time period. For example, an alternate payee might be entitled to 50% of all contributions (and gains/losses) that occurred during the marriage, but not before or after.
