In Idaho, all income earned during the course of a marriage is "community" income. In other words, such income belongs equally to both persons in the marriage. So, even though your husband began investing in his 401K prior to marriage, you would generally be entitled to 50% of the portion of the 401K earned after you both were married. The part of the 401K that your husband earned prior to your marriage would be considered his separate property.
