Employee and Employer Contributions
401(k) accounts consist of employee salary deferrals (what you contribute from your own paycheck) and employer matching or profit-sharing. It’s important to clarify in the QDRO whether both types of contributions (plus any investment gains) are being divided, and from which dates they’re considered marital property.
If you don’t specifically include employer contributions, there’s a risk they may be excluded from the division. This is even more critical when vesting is not immediate.
