If you have been living apart and separately from your spouse (not sharing a bed, eating meals together or pursing the same goals any longer) for a period of one year, it may be time to file for divorce. There are other reasons and ways to do this of course, and whether you file for divorce as a no-fault or at fault depends entirely on you and your situation. A no-fault divorce may be filed for if you are separated for one year (in most states), have irreconcilable differences and cannot mend the relationship. At fault means that one or both parties intends to complain that the other party committed adultery, is mentally ill, is about to be incarcerated for a period likely to exceed a year, has a sexually transmitted disease, or is otherwise unfit as a spouse. If you file for divorce, you need to have some idea of what the costs associated with the divorce are. You can also consult with a divorce lawyer, who will give you a fair idea of what to expect. Most often, the initial consultation with a divorce lawyer is free, so you won't have to worry about payment right then.
