You can't release or give up what you don't already possess!
You can quit claim anything.
From time to time at work, I quit claim my company’s interest in a piece of land where the title is cloudy and we have no desire to have an interest in said land and the land owner has asked us if we’d release it. It’s easier and faster to write a QC than it is to pour over decades of research.
This is an interesting situation here in the crazies. I see good points being made by people on both of the pro public access sides.
