The part of your husband's 401(k) which was acquired during the marriage is marital property subject to being equitably divided by the court in a divorce. For example, if your husband had contributed to the 401(k) for 30 years, but had only been married 10 of those 30 years, one-third of the 401(k) would be considered marital property, and two-thirds would be considered your husband's separate property.
