Employee vs. Employer Contributions
One of the first things a good QDRO needs to do is separate employee contributions from employer contributions. In many 401(k) plans, the employee’s portion is 100% theirs from day one. But employer matches or profit-sharing contributions may be subject to a vesting schedule. That means not all of the account’s total balance belongs to the employee until certain service milestones are met.
In your QDRO, you need clear instructions on how these contributions are split. Typically, a QDRO will only divide the “vested” portion of the account as of a specific cutoff date—often the date of separation or divorce. So if some employer funds weren’t vested as of that date, they’re typically off the table for division.
