If my spouse filed for a divorce, can I still get half of his 401k if I leave the marital home before being served?

Generally, the court shall set apart to each spouse such spouse's nonmarital property and shall divide the marital property and marital debts in such proportions as the court deems just after considering all relevant factors including: (1) The economic circumstances of each spouse at the time the division of property is to become effective, including the desirability of awarding the family home or the right to live therein for reasonable periods to the spouse having custody of any children; (2) The contribution of each spouse to the acquisition of the marital property, including the contribution of a spouse as homemaker; (3) The value of the nonmarital property set apart to each spouse; (4) The conduct of the parties during the marriage; and (5) Custodial arrangements for minor children. Marital property normally means all property acquired by either spouse subsequent to the marriage except: (1) Property acquired by gift, bequest, devise, or descent; (2) Property acquired in exchange for property acquired prior to the marriage or in exchange for property acquired by gift, bequest, devise, or descent; (3) Property acquired by a spouse after a decree of legal separation; (4) Property excluded by valid written agreement of the parties; and (5) The increase in value of property acquired prior to the marriage. Usually, all property acquired by either spouse subsequent to the marriage and prior to a decree of legal separation or dissolution of marriage is presumed to be marital property regardless of whether title is held individually or by the spouses in some form of co-ownership.
