Employee vs. Employer Contributions
The Betterment 401(k) Savings Plan likely includes both employee contributions and employer matching contributions. It’s important to distinguish which of these are marital property during divorce. A common method is to split only the portion that was earned during the marriage. This requires a precise calculation of contributions made between the date of marriage and the date of separation or divorce.
Employer contributions may also have a vesting schedule. This means that not all the employer-funded amounts may be available at the time of divorce. Any unvested portion typically remains with the employee spouse, while only the vested portion can be divided through the QDRO.
