The 1031 Exchange Agreement: What’s Actually in the Contract
When you engage a qualified intermediary, you will receive a stack of documents to sign, often within days of your relinquished property closing. Most investors sign quickly because the closing is on top of them, without fully understanding what each document does. Understanding the 1031 exchange agreement document package before you sign it helps you catch problems early and gives you confidence that your exchange is structured correctly. This article walks through the core documents in a typical exchange package in plain English, so you know what you are signing and why it matters.
Before your next closing, talk with Aspen Exchange so your documents are drafted and ready well ahead of your deadline, rather than assembled under time pressure.
The Exchange Agreement Itself
The exchange agreement is the master contract between you, the taxpayer, and the qualified intermediary. It establishes the QI’s role, sets out the rights each party has to the exchange funds, and formally restricts your access to the proceeds so the transaction qualifies as a deferred exchange under Section 1031 rather than a sale followed by a purchase. Key provisions typically include:
- A statement that the QI is acting as an independent intermediary and is not your agent for tax purposes.
- Language limiting your right to receive, pledge, borrow, or otherwise obtain the benefits of the exchange proceeds during the exchange period, which is what satisfies the constructive receipt requirement.
- The identification and exchange period deadlines that apply to your transaction, generally the 45-day identification window and the 180-day completion window.
- The QI’s obligations regarding how funds will be held, invested, and eventually disbursed.
- Termination provisions describing what happens if the exchange fails or the exchange period expires without a completed purchase.
This is the document that legally creates the exchange. Without a properly executed exchange agreement in place before your relinquished property closes, the IRS will generally treat your transaction as an ordinary taxable sale, so the timing of this signature matters as much as its content.
The Assignment of the Purchase and Sale Contracts
Section 1031 exchange rules require that the QI be assigned the rights, though generally not the obligations, under both your relinquished property purchase contract and your replacement property purchase contract. This is accomplished through a document usually called an Assignment of Contract or Assignment of Purchase and Sale Agreement. In practice, you as the seller (or buyer, on the replacement side) still sign the underlying contract and typically still show up at closing, but the assignment inserts the QI into the chain of title long enough to satisfy the technical requirement that the QI, not you directly, is the party acquiring and transferring the properties for exchange purposes. Both the relinquished property assignment and the replacement property assignment are needed, and each one is specific to that particular transaction, since a new assignment has to be executed for every property involved in the exchange.
The Qualified Escrow or Trust Agreement Governing the Funds
Alongside the exchange agreement, most QIs use a separate qualified escrow agreement or qualified trust agreement that specifically governs how your sale proceeds are held between closings. This document is what the regulations reference when they describe a “qualified escrow account” or “qualified trust,” which are two of the accepted ways a QI can hold funds without those funds being considered constructively received by the taxpayer. The agreement typically covers:
- Which financial institution holds the account and how the account is titled.
- Restrictions confirming that only the QI, not the taxpayer, can direct withdrawals, and that the taxpayer’s rights are limited exactly as described in the exchange agreement.
- Whether the funds are held in an account segregated for your exchange specifically, rather than commingled with other clients’ funds.
- How interest, if any, earned on the account is credited or handled.

The Notice of Assignment Sent to Closing Parties
Because the assignment of the purchase contract is a required part of a compliant exchange, the QI also sends a formal Notice of Assignment to the other parties in each transaction, typically the buyer of your relinquished property and the seller of your replacement property, along with their respective closing agents or title companies. This notice puts everyone on record that the contract rights have been assigned to the qualified intermediary and tells the title company how to handle the settlement statement and wire instructions. Skipping or mishandling this notice is one of the more common sources of last-minute closing delays, since a title company that receives wire instructions inconsistent with an unacknowledged assignment will often stop and ask questions before releasing funds.
The Written Identification Notice
The final document in a typical package is not signed at the start of the exchange but rather during the 45-day identification window. The written identification notice is the formal document by which you identify your candidate replacement property or properties to the QI, in writing, before the 45th day after your relinquished property closing. To be effective, the identification generally must unambiguously describe the property, commonly by street address or legal description, and must be received by the QI (or another eligible party under the regulations) by the deadline. A verbal mention to your QI or your agent is not sufficient. This document is short but unforgiving on timing, since a late or vague identification can cause the entire exchange to fail even if you ultimately close on qualifying property.

Why the Order and Timing of These Documents Matters
Each of these documents has to be in place at a specific point in the transaction for the exchange to hold up. The exchange agreement and the relinquished property assignment need to be executed before that closing occurs. The identification notice has its own independent 45-day deadline. The replacement property assignment needs to be executed before that closing. Missing the sequence, even if every document eventually gets signed, can create the same practical problem as never signing them at all, because the IRS looks at whether you had constructive receipt or an unrestricted contract right at any point along the way. This is part of why working with an intermediary who has a repeatable, disciplined process, and who coordinates directly with your closing agents, matters as much as the paperwork itself.

Frequently Asked Questions
Do I need to sign the exchange agreement before I close on my relinquished property?
Yes. The exchange agreement generally needs to be executed and the qualified intermediary formally engaged before the relinquished property closing. Signing it afterward is generally too late to structure the transaction as a valid exchange.
Does the assignment of contract mean the QI is buying and selling my properties?
Not in a practical sense. The assignment gives the QI the contractual rights needed to satisfy the exchange requirements, but you continue to negotiate the deal, attend closing, and handle the transaction as the actual party in interest. The QI’s role is largely a documentation and funds-holding function.
What is the difference between a qualified escrow and a qualified trust?
Both are IRS-recognized structures for holding exchange funds without the taxpayer having constructive receipt. A qualified escrow typically involves a third-party escrow holder and an escrow agreement, while a qualified trust involves a trust arrangement with a trustee. Different QIs may favor one structure over the other, but both are designed to accomplish the same protective purpose.
What happens if the Notice of Assignment does not reach the title company in time?
Closings can be delayed while the title company confirms the assignment and adjusts the settlement statement and wire instructions accordingly. Coordinating this notice early, as soon as a contract is executed, helps avoid last-minute scrambling near a closing date.
Can I change my identified replacement property after I submit the written identification?
Generally, you can revoke or revise an identification as long as you do so in writing before the 45-day deadline expires. Once the 45th day passes, the identification is generally locked in, which is why many investors identify more properties than they expect to actually purchase, within the applicable identification rules.
Who keeps copies of the exchange documents after closing?
Your qualified intermediary should provide you a complete closing package with copies of the exchange agreement, both assignments, the escrow or trust agreement, the identification notice, and settlement statements. Keep these with your tax records, since your CPA will need them to properly report the exchange on your tax return.
