Can an actuary be used when dividing 401k ets between parties divorcing?

I would like to know when dividing a 401K when one of the parties is the primary, other than using a Qualified Domestic Order to divide the et, can an actuary be used to calculate the future monies that would be due for the spouse that is the non-primary party. In other words, the husband works and gets a 401K and his wife files for divorce and she is a homemaker... how does the wife figure out how much money would be due to her in the future?
