1. Know What’s Divisible
Generally, retirement contributions made during the marriage are marital property. For the Mural Oncology Inc.. 401(k) Plan, this usually includes:
- Employee salary deferrals (pre-tax and/or Roth)
- Employer matching or profit-sharing contributions—if vested
- Account gains/losses during the period of division
If employer contributions are not yet vested, they may not be included. That’s why understanding the specific vesting schedule of this plan is critical. Otherwise, your QDRO might attempt to divide funds that don’t actually exist.
