If you are in a failed relationship and want to apply for divorce there are several ways in which to find help. First and foremost you may want to consult with family lawyers who are experienced in divorce and can tell you everything you need to do. In fact, they will do most of the work for you. You only need to instruct them to do it and add your signature to the forms.
It often helps to talk to a neutral third party when you have been under the kind of stress that a breakdown in relationship usually results in. Having someone explain what you need to do and offer their help can mean the difference in whether you cope with your divorce and come through it successfully, or whether you flounder in a sea of hopeless depression caused by not being able to make decisions or not know what decision would be best given a specific circumstance. Sometimes you just need someone who you can trust to be on your side to advise you.
