on neutral ground/territory

on neutral ground

In a location or setting to which neither side (e.g., in an argument, competition, etc.) has a connection and therefore gains no benefit or advantage. I find couple's therapy to be helpful because it gives each partner a chance to air their frustrations on neutral ground. The peace deal between the two countries was brokered on neutral ground in the European capital.
