Am I entitled to a portion of my husband's retirement and pension in a divorce in the state of IN? We have been married for 9 years.

It is likely that you could receive a portion of the retirement account.  Indiana generally provides for an equitable division of martial property (typically 50/50).  However, most attorneys will argue that you are only entitled to the portion that he invested during the nine (9) years of marriage.  You have some arguments that you can make yourself, but it can get kind of complicated to present in a question forum.  You best bet is to schedule a consultation with an attorney to see if this is something that they can help you with.
