Employee and Employer Contributions
401(k) plans like this usually include contributions from both the employee and employer. While the employee’s contributions are always 100% vested, employer contributions might not be. That means the value of the alternate payee’s share could depend heavily on the participant’s years of service.
If your divorce agreement calls for a 50/50 split of the retirement account, it’s essential to define whether that means 50% of total plan assets or 50% of only vested assets. A good QDRO attorney will clarify this to avoid disputes with the plan administrator later.
