First: Even if under age 70, at any age, make sure the title is clear and ready to lease.
Second, get the rights organized in a package and format that is easy for the heirs to transfer either while alive or when you die. Trusts work. I had to get triple certified copies of my uncle 's will from early 90's and affidavit from the attorney who luckily was still alive and had his marbles. Yeah.
Many people think the interests are/were worthless, so why mention them. My Uncle Harold and his attorney searched for value, found none yet still LUCKILY FOR ME mentioned the rights in his will and the Probate proceedings. The mention could have been more specific, but with a few dozen hours of digging, I figured it out. I thought I had it...
AND THEN I discovered MORE AND had to track down Harold's ancestor who died in 1961 and register what he inherited from her.
Get docs in a row includes registering your rights and ownership at the County Courthouse in Dewey or whatever county they are in.
Most of the rest of the heirs of this parcels are yet to be discovered. I'm still looking for them, so could use some help finding them and their probate/inheritance papers. No benefit for me and I'm tired of messing with this, but I have laid the groundwork for them. If I ever get the energy or time to track them down.
