The 1031 Exchange Addendum — What the Contract Must Say

The exchange lives in escrow paperwork, and the addendum is its passport: a short clause in your sale or purchase contract announcing the exchange, authorizing assignment to the qualified intermediary, and confirming the other side will cooperate at no cost to themselves. Miss it and closings still get rescued daily — but the clean version starts in the contract. Context: the full exchange guide.

What the clause actually does

Three jobs. Discloses the exchange (no one’s consent is legally required, but surprise assignments at closing tables create friction the clause prevents). Authorizes assignment of the contract to the QI — the technical step that makes the QI a party to the transfer, which the regulations’ safe harbor expects. Caps counterparty burden: cooperation “at no additional cost, expense, or liability,” with no delay to closing — the language that makes signing it a non-event for the other side.

Anatomy of a working clause

Sellers’ version, in substance: “Buyer acknowledges Seller intends to effect a tax-deferred exchange under IRC §1031. Seller may assign its rights (not obligations) under this Agreement to a Qualified Intermediary, and Buyer agrees to cooperate, provided such exchange imposes no additional cost, liability, or delay upon Buyer.” Buyers’ version mirrors it for the replacement purchase. Your QI supplies preferred language; most state contract forms carry a checkbox version. Any of them beats silence.

The edge cases the clause smooths

Simultaneous notices when both sides are exchanging (common in NNN transactions, where 1031 money meets 1031 money); assignment mechanics on auction and portal purchases with rigid contracts; and the occasional counterparty who balks at unfamiliar language — where the “no cost, no delay” sentence does its diplomatic work. One paragraph, zero dollars, and the exchange’s legal plumbing is in place before anyone’s clock is running.
