Colorado is a no-fault state, meaning you cannot assert that the divorce is the fault of your spouse due to abandonment. For more information about the grounds for divorce in Colorado, see http://www.freelegalaid.com/nav/colorado/divorce/article/grounds-divorce-colorado.You can file a fee waiver form with your divorce petition to ask the court to waive your filing fee. However, the fee waiver only applies to the court fees, and if you choose to hire a lawyer to represent you in this case, the waiver will not apply to those costs. For more information about how to have your fling fee waived, see http://www.courts.state.co.us/Forms/Forms_List.cfm?Form_Type_ID=176. Filing for divorce can be expensive, however, there are low-cost legal services available for those that need help but cannot afford to pay much for legal assistance.
