If gthere is a martial dissolution agreement and judgment between you and your former husband you need to carefully read the documents to see if the court retains jurisdiction with respect to the division of the assets and liabilities of your former marriage.If the judgment does not state that the court retains jurisdiction over your marital settlement then you cannot go back to court and seek a portion of your former husband's military retirement.If it does and there is no time period for the court retaining jurisdiction over your dissolution, you can. I suggest that you consult with a family law attorney with respect to your matter.
