Employee vs. Employer Contributions
Employee contributions are always considered “fully vested.” That means they belong to the participant 100% and can be divided through a QDRO without restriction. Employer contributions, however, often follow a vesting schedule. If the participant hasn’t worked for the company long enough, a portion of the employer contributions may not be fully owned.
This matters when valuing the account for division. Make sure your QDRO only divides the vested portion of the employer contributions, or specifically identifies how to treat any unvested amounts.
