Assignment & 1031 Exchange in a Commercial Purchase

Two clauses that are easy to overlook until they matter: whether you can assign the contract to your deal entity, and whether the deal can be a 1031 exchange.

General information, not legal advice.

Overview

Commercial buyers usually take title in a newly formed single-purpose entity (an LLC), and many want to structure the purchase as a 1031 like-kind exchange to defer capital-gains tax. Both depend on contract language that is easy to overlook.

If the assignment clause is too narrow, the buyer cannot move the contract into its intended entity; if the 1031 cooperation clause is missing, the exchange can be jeopardized.

Topics to check

Assignment to a single-purpose entityMedium confidence

A buyer should preserve the right to assign the contract to an entity it controls (an affiliate or single-purpose entity) without the seller’s consent, while remaining liable. A blanket "no assignment without consent" clause can block the standard practice of closing in a newly formed LLC.

Sellers legitimately want to know who is actually closing and may require notice and that the original buyer stay on the hook; a reasonable middle ground is consent-free assignment to a controlled affiliate with notice.

1031 like-kind exchange cooperationHigh confidence

Under Internal Revenue Code Section 1031, a taxpayer can defer gain on the exchange of real property held for business or investment for like-kind real property. A purchase agreement should include a cooperation clause obligating each party to accommodate the other’s exchange at no cost or liability to the cooperating party.

A 1031 exchange has strict timing: the replacement property must generally be identified within 45 days and the exchange completed within 180 days, and the funds must be handled by a qualified intermediary — the buyer cannot take actual or constructive receipt of the proceeds.

Coordinating the twoHigh confidence

Exchange and assignment language should be consistent: assignment of the contract to a qualified intermediary or exchange entity should be expressly permitted, and the cooperation clause should not require the cooperating party to take on extra cost, delay, or liability.

Because a botched exchange can trigger a large tax bill, the structure should be set up with a qualified intermediary and a tax advisor before closing, not at the closing table.

Key takeaways

  • Preserve consent-free assignment to a controlled affiliate or single-purpose entity.
  • Add a 1031 cooperation clause if either party may do an exchange.
  • Mind the 45-day identification and 180-day completion deadlines.
  • Use a qualified intermediary; never take receipt of exchange proceeds.
  • Set up any exchange with a tax advisor before closing, not at the table.

Legal-review notes

Guide confidence marker: Medium confidence.

  • 1031 rules are technical and change; confirm current IRS requirements and structure exchanges with a qualified intermediary and tax advisor.
  • Assignment and entity-structuring outcomes depend on the contract and governing law.

Frequently asked questions

Can I close in a different entity than the one that signed the contract?

Only if the assignment clause allows it. Buyers usually negotiate the right to assign to an affiliate or single-purpose entity they control without seller consent (often while staying liable). A blanket no-assignment clause can block closing in your intended LLC.

What are the 1031 exchange deadlines?

For a standard deferred exchange, the replacement property must generally be identified within 45 days of selling the relinquished property, and the exchange completed within 180 days. A qualified intermediary must hold the funds; missing a deadline can disqualify the exchange.

What is a 1031 cooperation clause?

A clause where each party agrees to reasonably cooperate with the other’s like-kind exchange — including assigning the contract to a qualified intermediary — at no additional cost, delay, or liability to the cooperating party.
