1. Employer Contributions and Vesting Schedules
Many 401(k) plans include both employee and employer contributions. However, employer contributions usually follow a vesting schedule. This means you may only be entitled to a portion of those employer contributions depending on how long the employee-spouse worked there.
If your spouse is not fully vested at the time of divorce, the unvested portion of the account may be excluded from division. Make sure your QDRO clearly states how to handle partially vested funds to avoid disputes later.
