Utah is not exactly a hotbed compared to other states, but it does have production in some areas. I would not touch that one year royalty assignment at all. The best recovery from a well is in the first year. Wouldn’t you want your family to get that instead!?
Be sure and get an attorney to review any contract to make sure that you understand the terms. Most leasing gives a royalty percent such as 1/8th, 3/16hs, etc. Never giving away 100%.
