1. Employer Contributions and Vesting
Many 401(k) plans include employer contributions that are subject to a vesting schedule. That means the employee must stay with the company for a certain period to gain full ownership. Any unvested portion at the time of divorce is not divisible unless the participant becomes fully vested later.
This creates two issues:
- The alternate payee might expect to receive a percentage of the entire balance, not realizing some of it hasn’t vested.
- The QDRO needs to account for whether unvested amounts should be included if they vest later—or if the award is limited to the vested balance as of the division date.
