1. Employee vs. Employer Contributions
The Adeia 401(k) Plan likely includes both employee and employer contributions. While all employee contributions are immediately yours, employer contributions often come with a vesting schedule.
In a divorce context, only the vested portion of the employer’s contributions can be divided. If your spouse is entitled to a share of your retirement, the court’s division won’t include amounts that were unvested as of the date of separation or division — unless otherwise agreed.
