Employee vs. Employer Contributions
In general, employee contributions are fully vested and should be included in the QDRO division. Employer contributions, however, may be subject to a vesting schedule. If your spouse isn’t 100% vested, only the vested portion may be divisible. You need to clarify the vesting status at the time of separation or the agreed division date.
Some plans also provide a profit-sharing component, like this one. Profit-sharing contributions may also have different vesting timelines and conditions, and that can impact how much the alternate payee receives.
