Employee and Employer Contributions
One of the first issues in dividing a 401(k) is determining how to allocate both employee (participant) and employer contributions. In most divorces, the split depends on the length of the marriage and the period over which contributions were made during the marriage.
Employer contributions may be subject to vesting, meaning the employee earns the right to them over time. If the divorce occurs before full vesting, you’ll need to specify how the unvested portion will be handled if and when it becomes vested later. An experienced QDRO attorney can include appropriate language to protect the alternate payee in case of future vesting.
