The short answer
Yes. An agent acting under a valid power of attorney that grants authority over real estate and contracts can sign the listing, the sale contract, the exchange agreement, the identification notice and the closing documents for you, and you remain the taxpayer. The power comes from state law and the document itself, not from the IRS; Form 2848 only authorizes representation before the IRS and does not let anyone sign a deed. Two limits matter: your agent cannot also be your qualified intermediary, and an ordinary power of attorney ends at your death, so an exchange still open then passes to your executor.
At a glance
| Who is the taxpayer | You, the principal; the agent only signs for you |
|---|---|
| Source of authority | State power of attorney law and the document's grant of powers |
| Form 2848 | Covers IRS representation only, not real estate signatures |
| Identification notice | Must be a written document signed by the taxpayer |
| Agent as intermediary | Not allowed; an agent of the taxpayer is a disqualified person |
| Incapacity | A durable power keeps working if you lose capacity |
| At death | The power ends; the executor carries an open exchange forward |
Your agent signs, but the exchange is still yours
A power of attorney makes the agent your representative for the acts it lists. When the agent signs a deed or an exchange agreement 'as attorney-in-fact', the signature is legally yours, so the taxpayer who sold and the taxpayer who buys the replacement are both you. Nothing in section 1031 requires you to sign in person.
The identification rule in Reg. Section 1.1031(k)-1(c)(2) requires a 'written document signed by the taxpayer'. An agent's signature under a power that covers the transaction is generally treated as your signature under state agency law; the regulation does not address it in terms, so make sure the document's real estate and contract powers are broad enough.
The IRS's own form is a different tool. The Instructions for Form 2848 say it is used 'to authorize an individual to represent you before the IRS.' It does not reach title companies or intermediaries, and Publication 947 explains how a non-IRS power can be used before the IRS only with a completed Form 2848 attached.
The person holding your power cannot be your intermediary
A qualified intermediary cannot be a disqualified person. Under Reg. Section 1.1031(k)-1(k)(2), that includes anyone who 'is the agent of the taxpayer at the time of the transaction', and an attorney-in-fact is your agent. Paragraph (k)(3) adds relatives within the section 267(b) family, which covers siblings, spouses, ancestors and lineal descendants.
So the adult child holding your power can sign everything on your behalf but cannot hold the sale proceeds. The proceeds must go to an independent intermediary, and the agent must not be able to reach them. See how to choose a qualified intermediary and whether your attorney, CPA or agent can act as intermediary.
The same independence protects you. An agent with power over your bank accounts and a voice in the exchange account would put the restrictions on receipt of funds in question.
Expect the title company, intermediary and sponsor to review the document
Title insurers commonly require the power of attorney to be recorded with the deed and may ask for confirmation that you are alive and have not revoked it. Intermediaries usually ask for a copy before they accept the agent's signature on the exchange agreement.
If replacement money is going into a Delaware Statutory Trust, the subscription agreement can usually be signed by your agent, but the investor standards are yours. Accredited investor status under Rule 501(a) is measured by your net worth above $1,000,000 excluding your primary residence, or by income above $200,000, or $300,000 jointly with a spouse, in each of the two most recent years; see DST accredited investor rules.
A narrow or old form may not be accepted. Powers limited to banking, or drafted before the property was bought, are a common reason closings stall.
Worked example: a daughter runs her father's exchange
Hypothetical; run your own numbers with your CPA. An 84-year-old widower owns a $900,000 rental and has given his daughter a durable power of attorney covering real estate, contracts and investments. He can no longer manage tenants and wants income without management.
His daughter signs the listing, the sale contract and the exchange agreement as attorney-in-fact, naming her father as taxpayer. An independent intermediary receives the $900,000. Within 45 days she signs and delivers an identification notice naming three DST offerings, and she signs the subscription documents after confirming her father's accredited status.
If her father dies on day 100, the power ends that day. The executor steps into the exchange, and the replacement can still close within 180 days; the executor's 1031 guide covers that handoff.
Review the power before you list the property
Have your attorney confirm the power is durable, covers buying and selling real estate, entering contracts, signing tax and investment documents, and dealing with intermediaries and securities. Ask whether your state requires specific language for gifts or for changing title, since a replacement taken in a new name may exceed a general grant.
If incapacity is the concern, the planning choices are wider than a power of attorney. 1031 options for an elderly parent compares exchanging with holding for the basis reset at death.
Related questions
Can my agent sign the 45-day identification notice?
An agent with authority over the transaction generally can, because the agent's signature is the principal's under state agency law. The regulation says only that the taxpayer must sign, so confirm with the intermediary before day 45.
Is Form 2848 enough for my agent to sell the property?
No. Form 2848 authorizes representation before the IRS. Selling and exchanging real estate needs a power of attorney under state law.
Can my son be both my agent and my intermediary?
No. An agent of the taxpayer and a lineal descendant are both disqualified persons, so he cannot hold the exchange funds.
What happens if I lose capacity during the exchange?
A durable power keeps working after incapacity, so the agent can finish the exchange. A non-durable power may end, which can stall the closing.
Can my agent put the replacement in a trust or LLC?
Only if the power allows it and the vesting keeps you as the same taxpayer for tax purposes. Changing title is often reserved to specific grants, so check the document first.
