Employee and Employer Contributions
401(k) plans are typically funded by employee salary deferrals and employer matches or other contributions. In a divorce, the QDRO can specify how both types of contributions are to be divided. The former spouse may be entitled to a portion of both—depending on the marriage timeline and contributions made during that time.
A standard method is to award the alternate payee 50% of the account balance accrued during the marriage. More accurate approaches use a coverture fraction to pinpoint marital contributions.
