Employee vs. Employer Contributions
The Building Blocks Therapy 401(k) likely includes both types of contributions. Most QDROs treat employee contributions as fully divisible, but employer contributions may be subject to a vesting schedule, which affects how much of that portion can be shared.
An unvested employer match isn’t transferable to an alternate payee (usually the ex-spouse). You need to confirm the current vesting status before deciding how to divide the account in your QDRO.
