Raise the POA question before closing week

A power of attorney can take time to draft, review, execute, notarize, witness, deliver, and approve. If the buyer waits until travel has already started or closing documents are ready, the transaction team may not have enough time to confirm acceptance.

Tell the attorney as soon as an absence or signing problem is possible. The attorney can decide whether a POA is appropriate and coordinate with the lender, title or settlement team, building, and other parties where needed.

New York form and execution questions belong to the attorney

New York has statutory power-of-attorney rules, including a statutory short form under the General Obligations Law. A buyer should not copy a form from the internet and assume it will work for a real estate closing.

Ask counsel what authority must be granted, who can serve as agent, how the document must be signed, whether witnesses or notarization are needed, whether originals are required, and whether the document must be accepted by any closing party before use.

Lender approval is a separate gate

For a financed purchase, the lender may have its own requirements for a buyer signing loan documents through a POA. Some documents, loan programs, investors, or underwriting conditions may require specific language or prior approval.

Ask the loan officer and attorney whether the lender must pre-approve the POA, whether the agent may sign loan documents, and whether final closing documents or the Closing Disclosure create additional timing issues.

Title, settlement, and building requirements can differ

A title company, settlement office, co-op transfer agent, managing agent, board, or sponsor may ask for specific document handling, identity verification, original signatures, recording language, or approval before relying on a POA.

The buyer should track each acceptance lane separately. Attorney approval alone may not mean lender, title, settlement, building, or board acceptance is complete.

Co-op and condo closings are not identical

A condo purchase may involve deed, title, mortgage, transfer-tax, waiver, and settlement documents. A co-op purchase may involve stock, proprietary lease, recognition agreement, board documents, managing-agent forms, lender documents, and closing instructions.

Because the document stack differs, the POA review path can differ too. Ask which documents the agent may sign, which must be signed by the buyer personally, and whether the building has its own instructions.

Closing credits, rebates, and funds need separate confirmation

A POA solves only a signing-authority question. It does not decide cash-to-close, wire instructions, credit treatment, buyer-side rebate treatment, tax treatment, or lender approval.

If a buyer-side rebate, seller credit, lender credit, grant, or other adjustment is part of the transaction, keep that issue in the closing-disclosure and lender-review lane. Do not assume an agent signing under POA can approve economic changes without proper review.

Buyer scenarios

A buyer will be overseas on the target closing date. The buyer should raise POA timing before the lender prepares final documents and before original-signature logistics become urgent.

A spouse wants to sign for both buyers. Counsel should review whether that is appropriate, how authority is granted, and whether lender and closing parties will accept the setup.

A co-op buyer expects the attorney to sign everything. The buyer should ask which documents can be signed by an agent and which building or lender items require personal action.

What changes the answer

The answer changes with condo versus co-op structure, cash versus financed purchase, lender rules, title or settlement requirements, building requirements, buyer location, identity verification, notarization, witness rules, original-document handling, and attorney guidance.

It also changes if the buyer is an entity, trust, non-U.S. resident, multiple-buyer transaction, sponsor purchase, estate transaction, or closing with last-minute document changes.
