Approach to Separation & Divorce

A final hearing brings closure but where contact arrangements are not adhered to by one or other parent or even the child/ children, psychological support can be important.

In separation/ divorce proceedings, it is often assumed young children are those most affected, which they can be. But adult ‘children’ can have unresolved feelings about both or one of the parents too.

In our practice we aim to listen to and incorporate the wishes and feelings of extended family members e.g. grandparents.
