What happens to a grandparent's relationship with a grandchild if the parents reconcile after separating?

If the parents reconcile after a period of separation, any existing grandparent contact order or arrangement doesn't automatically end just because the parents are back together - a court order remains in place until it's varied or set aside, and an informal arrangement remains whatever the family agreed to. That said, reconciliation often does change the practical dynamics: parents who previously disagreed about a grandparent's involvement may now share a united view, for better or worse, about how much contact should continue.

If the reconciled parents together want to reduce or end contact that was previously ordered, they would generally need to bring their own motion to change, showing that circumstances - now including their reconciliation - justify varying the existing order, rather than simply deciding between themselves to stop honouring it. A grandparent facing this situation retains the same right to respond and to argue that the existing relationship should continue, based on the same best-interests test as before. If reconciliation is affecting an existing grandparent contact arrangement in your family, get legal advice about your options rather than assuming the earlier order no longer applies.
