1. Vesting Schedules and Non-Vested Funds
The X4 Pharmaceuticals Inc.. 401(k) Plan likely includes employer contributions subject to a vesting schedule. That means your ex-spouse may not be entitled to 100% of the total balance if some of the funds aren’t fully vested. A well-drafted QDRO should specify how to handle unvested funds—whether to exclude them or to include only the vested portion as of a certain date (e.g., date of separation or divorce judgment).
