How do they determine who gets what in the divorce?

In Arkansas, all property acquired by the parties after marriage is considered marital property.  This means it is to be equally divided between the husband and wife with some limited exceptions.  The primary exceptions are inherited property and gifted property.  Aunt Sue died and left you her prized chihuahua paintings?  Those are yours to keep entirely.  Your wife gave you a shiny new set of golf clubs for Christmas last year?  Yours to keep.  Also, anything that was owned prior to the marriage will be awarded to that party.  CAVEAT:  There are always exceptions to the rule so make sure you check with an attorney before making any decisions based on what you believe your ownership is in certain property in your divorce case.
