No fault divorces began in Russia, where government used them as a way of taking power from the church, by granting divorces on the grounds of irreconcilable differences. Up until 1917 the church had been very restrictive in terms of permitting divorces, but soon with no fault divorces more and more people trapped in unhappy marriages were able to break free. The idea has spread across the world, with California being the first American state to implement the legal changes in 1969. Now no fault divorces are available in virtually every state in America, although many of them seem to apply them slightly differently.
Whether its infidelity, aggression or simply unhappiness, marriages can now be ended in a much easier way, without accusations and blame sending the spouse's relationship down the toilet. While infidelity or other breaches of the contract are not relevant to whether the divorce is actually awarded, they can affect other related matters such as the custody of any children involved.
One of the best things about no fault divorces is that they are usually processed by the court much faster than traditional divorce proceedings. Accusations and blame are not needed to dissolve the marriage, which really cuts down on the time and money that needs to be spent on calling it a day. Before the advent of no fault divorce law, one party had to accuse the other of adultery, abandonement or some other form of breaching the marital contract, in order to convince the judge to dissolve the marriage.
When a marriage needs to be ended, often it doesn't matter who is responsible. Usually both parties want it brought to a swift and final conclusion, and not having to accuse and prove the errors of a partner is a painful obstacle in their way. In the past, some people had to be found guilty of adultery in court in order to be granted a divorce.
If you and your spouse are agreed to divorce, but cannot conclusively blame one party for the breakdown, then a no fault divorce is the perfect way of obtaining that divorce without ruining relations with your soon-to-be ex-spouse.
