Employee and Employer Contribution Divisions
In most 401(k) plans, employees contribute pre-tax dollars from their paychecks, and employers often match a portion of those contributions. In a divorce, both contributions are divisible, but only the portion accrued during the marriage is considered marital property.
However, determining the value that accrued during the marriage may require statements from the date of marriage and the date of separation, and it’s essential to factor in any contributions made after separation but before judgment. Talk to your attorney or QDRO professional about how to handle these calculations correctly.
