((( Russia ))) was the first place to get No Fault Divorce
en.wikipedia.org/wiki/No-fault_divorce#Russia
No-fault divorce was introduced by the Bolsheviks following the Russian Revolution of 1917.[6] Before the Revolution, religious institutions tended to define family life. It was the ecclesiastical law of the Russian Orthodox Church that controlled the family, marriage, and divorce. For example, the official registration of birth, death, marriage, and divorce was the responsibility of the parish church. Under these non-secular laws, divorce was highly restricted (but always somewhat available, since the Russian Orthodox Church allows divorce for adultery, desertion, and physical cruelty).
The 1918 Decree on Divorce eliminated the religious marriage and the underlying ecclesiastical law, replacing them with civil marriage sanctioned by the state. Divorce was obtained by filing a mutual consent document with the Russian Registry Office, or by the unilateral request of one party to the court. The divorce law under the Bolsheviks did not penalize the husband with alimony, child support, or debtor's prison for non-payment, as every individual was to be provided for by the state anyway. The two partners were entirely free of legal obligations to each other after divorce. The concept of child support, however, was introduced to the family law of Russia in the 1990s after the fall of the Soviet Union.
