Employer Contributions and Vesting
Many corporate 401(k) plans include employer matching contributions, which are often subject to a vesting schedule. For example, Mehler Inc. may state that its matching contributions vest at 20% per year. If your divorce happens early in employment, some of those employer contributions might not be fully vested—and the unvested portion may be forfeited.
Your QDRO should state whether it divides the vested amount only or attempts to share post-divorce vesting, depending on the state and plan terms. Most administrators will honor only what is vested as of the division date.
