As will Wills/ and other legal matters you really need to talk to your lawyer. This is just a sugestion, you said your executor lives in Texas and everything else is in S.D.. And really have never lived there, right?
Why not move all your stuff to Texas and be done with it. And make sure to re-write your will, with an attorney in the state.
I've been dealing with my wife estate since she passed away in August (No will). Our home state is Texas and it's where we've lived most of our adult life together. So I had to get a lawyer to get you will into probate court. I will be completed this month.
Now, my lawyer has told me some pretty good stories about different states having differenttt laws concerning wills and probate. Texas is one of the easiest states to have as your home state. Now, if you own property of any kind in another state, this is where it gets tricky. Now you have to get that property probated in the state. I'm not a lawyer, just passing along some advice.
