If you have no children, no joint assets ( including retirement accounts) or liabilities, both of you have the means to support yourselves, there is no name change, it is a short term marriage and you are proficient with legal documents then you might not need an attorney.
It is in your best interest to at least have a consultation with an attorney so that you know what your rights and obligations are and you do not miss any issues that you may be unaware of.
Just because a credit card or a house is in one parties name does not necessarily make it that person's sole asset or liability.
If you miss something at the time of your divorce, such as obtaining a waiver of a spouses interest in your retirement account, it may be very costly to correct the error down the road.
