Step 1: Determine What Portion Is Divisible
Start by establishing which marital portion of the 401(k) is subject to division. This typically includes contributions and growth made during the marriage, including any employer matches earned during that time.
One of the only ways to determine the exact balance is to obtain a plan statement as close to the date of separation or divorce as possible. Your attorney or QDRO professional should request this directly from the plan administrator.
