Employee and Employer Contributions
Like most 401(k)s, the Tsmc North America 401(k) Plan likely includes both employee deferrals and employer matching contributions. As an alternate payee, you may be entitled to a portion of both—but only if they are vested. Be sure your QDRO clearly distinguishes which part of the account is being divided. If the plan has different rules for employer matches (as many do), it has to be spelled out in the order.
