The trigger is almost always land, and the reason is mechanical rather than legal-theoretical. A bank in another state can be paid or persuaded; a county recorder cannot be. Title to real property is a matter of the local land records, and the authority to convey it has to be established somewhere the local recorder will recognize. That is why published probate's rule of thumb, that real property is administered where it sits, is the sentence to carry away, and why a second home, an inherited family cabin, farmland or a timeshare in another state is the fact pattern that produces this problem far more often than an out-of-state brokerage account does.
But a second full administration is a possibility rather than a certainty, and this is the half most guidance omits. Minnesota, whose article 4 follows the uniform text, offers the home-state representative a route that does not involve opening anything. Under 524.4-204, where no local administration or petition for one is pending, a domiciliary foreign personal representative may file two things with a court in a county where the decedent's property sits: a certified or authenticated copy of their appointment and of any official bond, and a notice of intent to exercise the powers of a local personal representative. The court administrator then publishes notice once a week for two consecutive weeks, at the estate's expense.
Then 524.4-205 does the work. Sixty days after that filing, the domiciliary foreign personal representative "may exercise as to assets in this state all powers of a local personal representative and may maintain actions and proceedings in this state." The catch is in the same section: that power "shall not be exercised if a resident creditor of the nonresident decedent has filed a written objection thereto within 60 days" of the filing. So the route is a waiting period with a veto attached, and the veto belongs to local creditors, which is the interest a local proceeding exists to protect in the first place.
A narrower shortcut sits one section earlier and needs no court at all. Under 524.4-201, sixty days after a nonresident's death, anyone indebted to the estate, or holding an instrument evidencing a debt, obligation, stock or chose in action belonging to it, may pay or deliver to the domiciliary foreign personal representative on proof of appointment plus an affidavit that no local administration or petition for one is pending. That covers a bank balance, a bond, a certificated security or an amount owed under a contract. It does not cover land, which is the pattern throughout this area: the informal routes reach money and paper, and real property keeps needing a court.
What this means for planning is that the work is done years earlier, at the titling stage. Property that never enters the estate never reaches a second court. A house held with a right of survivorship passes to the surviving owner by operation of the title. Some states offer a deed that names a beneficiary and takes effect at death without probate. A house retitled into a funded revocable living trust is owned by the trust rather than by the person, so the trustee deals with it under the trust's terms wherever it sits. Each of those has its own trade-offs, covered on its own page, and each removes the property from the problem rather than making the second proceeding cheaper.
Two boundaries worth stating plainly. First, none of this is a rule about which state's law decides who inherits the property. That is a separate question, it was not established at primary source for this page, and every general statement of it circulating online should be checked against the law of the actual state. What the sections above establish is where the administration happens and who may act. Second, the details differ by state, including whether a state has adopted the foreign-representative article at all. Minnesota is used here because its enactment is readable in full; the state where the property actually sits is the one that governs, and it may say something different.
