1. Employee and Employer Contributions
A key issue in QDRO drafting for 401(k) plans is distinguishing between employee and employer contributions. The employee’s salary deferral contributions are fully theirs and generally fully vested. However, employer contributions might be subject to a vesting schedule. That means the participant may not own the entire employer-funded portion depending on how long they’ve worked at the company.
When dividing the account, you’ll need to consider whether unvested employer contributions should be excluded. Some QDROs attempt to divide both vested and unvested funds, but most plan administrators only permit division of vested benefits.
