1. Employee vs. Employer Contributions
This 401(k) likely includes both employee salary deferrals and employer contributions. In many divorces, parties agree to divide the total account as of a certain date, but you can also limit the division to just the marital portion (i.e., contributions and gains made during the marriage).
Employer contributions may be subject to vesting schedules. If parts of the employer match weren’t vested at the division date and later vest, those would typically not be included in the alternate payee’s share—unless otherwise agreed.
