Most of what we write about exchanges concerns deadlines, structures, and tax mechanics. This one is about two paragraphs of contract text, which sounds trivial until you meet the owner who is three days from closing and discovering that the buyer's attorney will not agree to an assignment.
The cooperation clause is not glamorous. It is also close to free, takes ten seconds to include in a first draft, and becomes surprisingly expensive to add once everyone has signed.
What the clause is actually doing
A 1031 exchange requires that your qualified intermediary step into the transaction. You cannot receive the sale proceeds yourself; the intermediary has to be positioned to receive them, which is typically accomplished by assigning your rights under the purchase and sale agreement to them.
If the contract is silent on assignment, or worse, prohibits it, you have a problem that is not really about tax at all. It is a contract problem, and the person who has to solve it is the counterparty, who has no obligation to help.
So the clause does two jobs:
- Notice. It states plainly that you intend to perform an exchange, so nothing about the intermediary's appearance at closing is a surprise.
- Permission to assign. It secures the counterparty's agreement, in advance, to the assignment that makes the exchange work.
The language, both directions
Intermediaries publish variations of this, and the substance is consistent. Selling the relinquished property, the clause runs roughly:
Buyer is aware that Seller intends to perform an IRC Section 1031 tax-deferred exchange. Seller requests Buyer's cooperation in such an exchange and agrees to hold Buyer harmless from any and all claims, costs, liabilities, or delays in time resulting from such an exchange.
Buying the replacement property, it flips, with one important addition:
Seller is aware that Buyer intends to perform an IRC Section 1031 tax-deferred exchange. Buyer requests Seller's cooperation in such an exchange and agrees to hold Seller harmless from any and all claims, costs, liabilities, or delays in time resulting from such an exchange. Seller agrees to an assignment of this purchase and sale agreement to a qualified intermediary by the Buyer.
That final sentence is the operative one. Notice without assignment permission is only half the protection. Use your intermediary's preferred wording rather than these as drafting language; the point here is what the clause must accomplish, and your attorney should approve the actual text.
| Element | What it does | Why the other side accepts it |
|---|---|---|
| Notice of intent | Removes surprise at closing | Costs them nothing |
| Assignment permission | Lets the QI step into the contract | No change to price or terms |
| Hold harmless | Protects them from cost and liability | It is protection for them |
| No additional cost or delay | Caps their exposure | Explicitly limits their burden |
Why counterparties almost always say yes
The hold-harmless language is why this is an easy ask. You are not requesting that the other side take on risk, expense, or delay. You are telling them an intermediary will appear in the paperwork, and promising that it will cost them nothing.
Experienced commercial buyers and sellers see this constantly and sign without comment. Resistance usually comes from inexperience, an attorney encountering it cold, or a residential-style transaction where nobody has met the concept before. All of which is much easier to work through during negotiation than during closing week.
Where it goes wrong
- Nobody mentions the exchange until late. The most common failure. Raise it when the contract is being drafted, not after signature.
- The contract bars assignment outright. A standard anti-assignment provision can conflict directly with the mechanics. It needs a carve-out for assignment to a qualified intermediary.
- Only one side gets the clause. Both transactions need it: the sale and the purchase.
- The clause is present, but nobody actually assigns. The paperwork still has to be executed and delivered before closing, which is your intermediary's job to drive.
None of these are exotic. They are the kind of thing that produces a frantic week, an annoyed counterparty, and occasionally a failed exchange over something that would have been a non-issue in the first draft.
The practical instruction
Tell your broker and your attorney you intend to exchange before the listing agreement and before any offer is drafted, and ask your intermediary for their preferred clause language early enough to hand to counsel. This is the same discipline that governs vesting and state withholding: each is trivial in week one and painful in week twenty. Your attorney drafts and approves the actual contract terms; what we do is make sure the requirement is on the table before anyone signs, which is why it sits at the front of our exchange process.
Common questions about 1031 exchange contract language
Is a cooperation clause legally required?
No. An exchange can be valid without one. But it is standard practice because it secures the assignment rights the structure depends on and prevents disputes at closing.
What is the most important part of the clause?
The counterparty's agreement to an assignment of the contract to your qualified intermediary. Notice of intent alone does not give you that permission.
Will the other side object?
Rarely, because the clause holds them harmless and imposes no cost, delay, or liability. Objections usually reflect unfamiliarity rather than a real concern.
Do I need it on both the sale and the purchase?
Yes. Each contract needs its own version, drafted from the appropriate side of the transaction.
What if my contract is already signed without it?
You may still be able to proceed with an amendment or a separate assignment agreement, but you now need the counterparty's voluntary cooperation. Talk to your attorney and intermediary immediately.
