1. Employee and Employer Contributions
One of the most common complications in dividing a 401(k) is figuring out how to split both the money contributed directly by the employee and any matching or profit-sharing contributions made by the employer. These represent different sources of funds and may fall under different vesting rules.
- Employee contributions are always 100% vested and can be divided without restriction.
- Employer contributions may be subject to a vesting schedule. This means the participant may not own all of it until they’ve worked at the company for a certain number of years.
