What the affidavit says is the whole mechanism, so it is worth reading as a list of promises rather than as a form. Utah's version requires the successor to state four things: that "the value of the entire estate subject to administration, wherever located, less liens and encumbrances, does not exceed $100,000"; that 30 days have elapsed since the death; that no application or petition for the appointment of a personal representative "is pending or has been granted in any jurisdiction"; and that the claiming successor is entitled to payment or delivery. Minnesota's list is the same four, with one further statement required only where a state or county agency presents the affidavit on a medical assistance claim, and its threshold sentence is worded differently, reaching "the value of the entire probate estate, determined as of the date of death, wherever located, including specifically any contents of a safe deposit box, less liens and encumbrances."
Three limits follow from that, and each of them is where people go wrong.
The ceiling is measured against the estate, not against the item. This is the trap that catches the most people. A successor with a $6,000 credit union balance to collect does not ask whether $6,000 is under the threshold; they have to swear to the value of the entire estate subject to administration. One asset that pushes the total over the line makes the affidavit unavailable for everything, including the small account that prompted the question.
It reaches personal property. Utah's operative sentence obliges "any person indebted to the decedent or having possession of tangible personal property, including an instrument evidencing a debt, obligation, stock, or chose in action" to pay or deliver it. Minnesota's covers the same ground and names safe deposit boxes expressly, requiring the company controlling access to deliver the entire contents. Land is in neither list, and no amount of being under the threshold brings it in. A house in the decedent's sole name is a probate matter whatever else is true.
Collecting is not keeping. Minnesota's subsection (c) is explicit: the claiming successor "shall disburse the proceeds collected under this section to any person with a superior claim" under the exempt-property and order-of-payment sections of the same chapter. The affidavit is a collection device, not a discharge of the decedent's debts, and signing one puts the successor in the position of having to sort out who gets paid first without a court supervising the order.
The state-by-state detail is where the two examples stop resembling each other, and that divergence is the point. Both states let a vehicle be retitled on the affidavit, but Utah's version is capped and carved out: the Motor Vehicle Division must transfer title to "not more than four boats, motor vehicles, trailers, or semitrailers" on presentation of the affidavit, and for that purpose the $100,000 test is applied to the estate excluding those vehicles, so a car can move even where the ordinary ceiling is close. Minnesota's registrar provision has neither the cap nor the carve-out. Utah separately excludes shares of stock in a water company from the whole part. Minnesota adds two features Utah's section does not have: a state or county agency holding a medical assistance claim may itself present the affidavit to a financial institution, and the person controlling a safe deposit box "need not open the box or deliver the contents" if it has received an objection, has reason to believe there would be one, or the lessee's key or combination is not available. Both states also require a transfer agent to change registered ownership of a security on presentation of the affidavit, which is how an odd lot of stock certificates moves without a court order.
What it does not do is decide anything. No court determines who the heirs are, no notice is published, and no creditor window opens. That is the source of both the speed and the exposure. Where the family is small, the facts are clear and everyone agrees, the trade is obviously worth making. Where there is a stepchild, an estranged sibling, a second marriage or a business, the absence of an adjudication is a live risk rather than a saving, and the point of a full administration is that it produces an order that is hard to unwind later.
