Employee & Employer Contributions
Most 401(k) plans include two major funding sources: employee contributions and employer match or profit-sharing contributions. The QDRO needs to specify exactly what percentage or dollar amount of these contributions will be paid to the alternate payee.
One common approach is to divide only the marital portion—the contributions and growth from the date of marriage to the date of separation or divorce—but that depends on your state laws and settlement terms.
