Employee and Employer Contributions
Employees contribute to their 401(k) on a pre-tax or Roth basis. Employers may also make matching or profit-sharing contributions. The QDRO must clearly state how contributions are divided, particularly if you’re asking for a percentage/slice of the account as of a certain date, rather than a fixed dollar amount.
For example, a QDRO may give an alternate payee “50% of the participant’s account balance as of the date of divorce, plus or minus gains and losses.” This includes employee contributions and any vested portion of employer contributions as of that date.
