Does the probate involve your last parent? If so, are you and your siblings the only heirs according to the Will? If yes, then just do an intestate probate. Forget the Will. (If there is someone in that will that isn’t a sibling then they might fight to get the Will submitted) but like I said, if it is just you guys and everybody is share and share alike, then I don’t see much of a problem. If all that is left for the inventory is real property, then you can do this probate yourself. North Dakota has a website for the paperwork, print it out and follow the directions. This could be amazingly simple if everyone involved is all Zen with the situation. The ND probate I did was older than 7 years…but don’t waste any more time, ND like many other States have a type of adverse possession and you don’t want to lose what property you have, especially the minerals. Opening the probate will at least reset the clock for you. (I think 20 years of no activity)
(When I say forget the Will, I mean don’t worry about it, go ahead and include it in the probate so it doesn’t appear you are hiding anything, let the judge decide if he wants to accept the Will or not. It won’t change your outcome if the above scenario is accurate.)
