I live in NJ. My husband purchased the house less then 1 month before we got married. Is this considered marital property and will it be divided

You may be entitled to a portion of the increase in value of the house form the time of purchase to the time of divorce.  If you are paying towards the utility bills (gas, water electric) you may not have any recourse. But if you are contributing to the mortgage, you may be able to claim entitlement to a portion of the equity in the house.  The more important issue is the way you are both dealing with money - it is the number 1 reason couples fight - see a counselor before things get too far out of control !
