Employee vs. Employer Contributions
In a 401(k) plan, account balances may include:
- Employee salary deferral contributions (fully vested)
- Employer matching contributions (may be subject to vesting)
- Employer profit-sharing contributions (also usually subject to vesting)
When dividing the account, it’s important to determine whether the division includes only vested amounts, or if the nonemployee spouse is entitled to a share of all contributions regardless of vesting status. Generally, only vested funds can be paid to the alternate payee, but in some cases, plans may apply different rules or interpret QDRO language differently if not drafted precisely.
