Grounds for Divorce
When filing for a divorce, it's necessary to point out one of the legally established grounds for divorce. Oregon is a pure no-fault state. The only valid ground for divorce is "irreconcilable differences." Any other causes that may lead to the divorce cannot affect the settlement, so neither spouse needs to disclose those private details of the marriage or prove the misconduct of the other.
In Oregon, the plaintiff's intention to start the divorce case is enough. He/she doesn't have to seek the spouse's consent.
