If the previous probate was not conducted in North Dakota, you would probably need an ancillary probate in ND to receive royalty and that would be how I handled ND property. ND does not recognize probates from other states. This is just general advice. You might think about who is doing this probate and what state. I'd want to make the most of the probate process and that would mean probating in ND.
