The Owner Died Mid-Exchange: What the Executor Can Still Do About Completing It

Only the taxpayer who sold can buy, and after death that taxpayer is the estate or the trust

A deferred exchange is one taxpayer's transaction: the person who transferred the relinquished property must receive the replacement. When that person dies with money at the intermediary, the taxpayer continues as the estate, or as the formerly revocable trust that now owns the exchange rights, and the fiduciary signs where the decedent would have. The same-taxpayer rules explain why the identity matters and which changes of form the IRS tolerates.

What breaks the exchange is distribution. If the personal representative pays the intermediary's funds out to the heirs, or has the replacement deeded to them directly, the heirs did not sell anything and cannot complete a sale they were never party to; the estate has received the money and the gain is recognized. The order is fixed: the estate acquires, the estate holds, and only then does the estate distribute the replacement under the will or the trust.

A revocable trust is the easier case. The successor trustee usually takes office on the grantor's death under the trust's own terms and needs no court order, so the intermediary can act on a certification of trust within days. A property held in the decedent's own name goes through probate, and the rest of this page is about doing that fast enough.

Getting authority inside the clock: informal appointment, special administrator and what the letters allow

Arizona's enactment of the Uniform Probate Code shows the timing a fiduciary can expect in a code state. Under A.R.S. section 14-3307 the registrar shall appoint the applicant as personal representative in an informal proceeding once at least 120 hours have elapsed since the decedent's death and the required findings are made; if the decedent was a nonresident, the order is delayed until 30 days after death unless the domiciliary representative is the applicant. Informal appointment establishes the representative's status and powers in full.

If even that is too slow, A.R.S. section 14-3614 allows a special administrator to be appointed informally on the application of any interested person when necessary to protect the estate before a general personal representative is appointed, and by the court in a formal proceeding, without notice if an emergency exists. A special administrator appointed by the court has the powers of a general representative except as limited in the appointment under section 14-3617, so the order should name the exchange.

Once appointed, A.R.S. section 14-3715 lets a personal representative, acting reasonably for the benefit of the interested persons and subject to the will or a court order, perform the decedent's contracts that continue as obligations of the estate, acquire or dispose of an asset including land in this or another state, and sell, mortgage or lease estate property. An exchange agreement and an identified replacement are exactly such contracts. States outside the code have their own timetables, and some require a court order to sell or buy real estate; ask probate counsel on day one which rule governs your decedent.

The deadlines do not pause for probate, and the decedent's final return can shorten them

Reg. section 1.1031(k)-1(b)(2) ends the identification period at midnight on the 45th day after the relinquished transfer and the exchange period at midnight on the earlier of the 180th day or the due date, including extensions, of the return for the year of transfer. For a sale in the last quarter of the year the second limb bites: the decedent's final Form 1040 is due, per Publication 559, at the same time it would have been due had death not occurred, generally April 15, so the representative must file an extension for the decedent to keep the full 180 days.

The only published postponement is Rev. Proc. 2018-58, section 17: when an IRS news release announces relief for a federally declared disaster, 45-day and 180-day deadlines falling on or after the disaster date are postponed 120 days or to the last day of the general disaster extension period, whichever is later, but never beyond the return due date with extensions or one year. A death is not on that list, and the page on extending the deadlines confirms there is no other route.

The estate also has its own return. Under the Form 1041 instructions a domestic estate with gross income of $600 or more must file, by April 15 for a calendar-year estate or the 15th day of the fourth month after a fiscal year end, with a five-and-a-half-month extension on Form 7004; the fiduciary should also file Form 56 and obtain an EIN at once, because the intermediary will need the estate's number on the replacement closing.

Hypothetical: a December 10 sale, a January 5 death and 97 days to find authority and close

Round numbers, hypothetical: the owner sold a $1,000,000 rental on December 10 and died on January 5, day 26 of the exchange, having identified nothing. The daughter named in the will applies for informal appointment on January 12, after the 120 hours, and holds letters by January 20, day 41. She has four days to deliver an identification list, which she can still do because the 45-day period belongs to the taxpayer and she is now the taxpayer's representative.

Day 180 is June 8, but the decedent's final return is due April 15, so without an extension the exchange period would end on April 15, day 126. She files Form 4868 for the decedent, which moves the due date past June 8 and restores the full 180 days. She identifies two all-cash DST interests and a small net-leased building, and the estate closes on the two trust interests in March on subscription documents signed by her as personal representative, with the estate's EIN.

The replacement interests are now estate property, held until the probate closes and then distributed to the heirs by percentage. Whether finishing was the right choice, rather than letting the exchange fail and paying the tax, depends on the income-in-respect-of-a-decedent rules that the executor's guide works through; run that comparison with the estate's CPA before the identification letter goes out.

Why a short clock points to a debt-free DST, and the checklist for the first ten days

An estate cannot easily borrow, and a lender will not close a mortgage with a representative whose letters are days old. An all-cash DST interest has no loan, no inspection period and no negotiation, and the page on closing speed explains why estates use them when day 180 is near. The interest is illiquid, the trustee sets the sale date, distributions can be cut and principal can be lost, so the fiduciary should document why the estate accepted those terms rather than recognising the gain. Settling an estate that then holds both trust interests and real property is covered on its own page.

• Locate the exchange agreement, the closing statement and any identification letter; calculate day 45 and day 180 from the relinquished closing.
• Apply for informal appointment, or a special administrator if the 45-day deadline is inside the probate timetable.
• Obtain an EIN, file Form 56, and extend the decedent's final return if its due date falls before day 180.
• Send the letters or trust certification, the EIN and the identification to the intermediary, who must accept your signature before you can close.
