The Grounds for Divorce are the legal reasons a court can allow you to dissolve the marriage contract you made with your spouse. These grounds, or legal reasons, fall into two categories: fault-based and no-fault divorces. As a general rule, a fault-based divorce such as cruel and inhuman treatment, habitual drunkenness, or adultery, requires more proof than a no-fault divorce and may not get you any different outcome in court than you could get in a no-fault divorce. A no-fault divorce, based on irreconcilable differences or a one-year voluntary separation, will generally require less proof than a fault-based divorce but may require the cooperation of your spouse. An experienced divorce lawyer can help you decide whether you would be better off filing for a no-fault or a fault-based divorce, or both.
