I think, we can never answer this question with generalisation. Some children have more difficulties with their parents unlucky relationship. They experience traumatical moments, which can change their mental conditions. Than is a divorce not real the hurting experience. Before parents tell their children about divorce, the little souls have always feelings about allienation in family, problems and conflicts work against a healthy family life. It is a important difference between children, who are traumatized by parental violence (also means verbal exchange) and children with a harmonical family experience. Children can cope sometime with a strong resilience, but sometime they struggle with mental disorders. Losing a main care person is a traumatic process, in this situation should parents remember in their responsibilities as childrens guidance and protection against emotional stress. Visits and shared responsibilities can help the child, when not difficult problems argue against contacts.
