Im in the process of divorcing and is it true that I can be entitled of half of my ex's retirment fund. weve been married for 9 years.
Not exactly. You are generally entitled to half the contributions to the fund during the marriage plus any growth in the value of those deposits (or less any losses) from whatever they were invested in. Contributions before the marriage, after separation, and profits or losses on that money is his separate property in a divorce.
