Thanks for providing this detailed updates. I understand less than half of what I read, but that's on me...
From what I gather regarding the issue related to Rob Kuntz-
In general, there is a strong desire for finality in estates. Therefore, once there is proper publication of notice, a clock starts ticking for people to file their claims against the estate. The amount of time varies depending on jurisdiction, but let's say it's 90 days.
If you do not file your claim within 90 days, then your claim is "time-barred." Here, it's referred to as the "statute of limitations," which is one way of putting it, although I normally don't think of it in those terms (normally, a statute of limitations refers to actions being time barred, such as a requirement to file a breach of contract within four years of the breach). But it's the same idea.
So the various discussions can be boiled down to this-
1. When was the publication of notice?
2. What was the deadline for filing a claim based on the publication date?
3. RK's claim was filed after the deadline, therefore he does not have a claim.
