Can Two People Have Power of Attorney at the Same Time?

The short answer: yes. A power of attorney can name two, three, or more people to act as agents at the same time, and it can name successors to take over when the first agents cannot serve. The question that matters is whether the co-agents may act separately or must act together, and in New Jersey, New York, and Connecticut the default answer is the same: unless the document says otherwise, co-agents must act jointly. A “dual” power of attorney that does not address the point produces two agents who each need the other’s signature for every transaction, which is the opposite of what most people naming two children intend.

This article explains what a dual or co-agent power of attorney is, the default rules in each of those states, how liability is shared, why banks resist these documents, and how to draft one that works.

What Does “Dual Power of Attorney” Mean?

The phrase is not a legal term. People use it to describe three different arrangements:

• Co-agents, two or more people named to serve at the same time.
• A primary agent and a successor agent, where one person serves and the other steps in only if the first dies, resigns, or becomes unable to act.
• Two separate documents, such as a financial power of attorney naming one person and a health care directive naming another, or a general power of attorney plus a limited one for a single real estate closing.

Each is lawful in all three states. The first is the one that causes trouble, and the trouble comes from the default rules.

What Are the Default Rules for Co-Agents?

New Jersey. Under N.J.S.A. 46:2B-8.7, a power of attorney “may provide that the attorneys-in-fact may act severally or separately,” in which case “any one of the appointed attorneys-in-fact may exercise all powers granted,” or it “may provide that the attorneys-in-fact shall act jointly,” in which case “the concurrence of all appointed attorneys-in-fact is required to exercise any power.” If the document “does not expressly provide whether the attorneys-in-fact are to act severally or separately, or are to act jointly, such attorneys-in-fact must act jointly.” When one of several agents dies, resigns, or becomes disabled, the authority “may be exercised by the one or more who remain” unless the document says otherwise, and the document may also provide that agents act successively.

New York. Under General Obligations Law section 5-1508, “unless the principal provides otherwise in the power of attorney, the co-agents must act jointly.” New York adds a safety valve: a co-agent may act alone when “prompt action is required to accomplish a purpose of the power of attorney and to avoid irreparable injury” and another co-agent is unavailable because of “absence, illness or other temporary incapacity.” A successor agent “has the same authority as that granted to an initial agent” unless the document provides otherwise, and the principal may set specific rules of succession.

Connecticut. Connecticut’s Uniform Power of Attorney Act, at General Statutes section 1-350j, departs from the uniform act’s usual default and is the strictest of the three. “Unless the power of attorney otherwise provides by use of the word ‘severally’ in the power of attorney that each agent acting alone is able to exercise the power conferred, each coagent shall exercise its authority jointly.” A Connecticut document that says the agents may act “independently” or “separately,” but never uses the word “severally,” arguably leaves them bound to act together. A successor agent “may not act until all predecessor agents have resigned, died, become incapacitated, are no longer qualified to serve or have declined to serve” unless the document says otherwise, and the principal may give an agent or another person the power to name successors.

The practical consequence in all three states is that a parent who names two children as co-agents without addressing the question has created a document that requires both signatures on every check, every account form, and every deed. If the children live in different states, or stop speaking, the document fails when it is needed.

Can Co-Agents Act Independently?

Only if the document says so, in the manner each state requires. When it does, either agent may act alone on any matter, and a bank or broker may rely on one signature. Many attorneys draft co-agent powers of attorney this way, so that the second agent provides redundancy rather than a veto, and then add a requirement of joint action for a short list of major decisions such as selling real estate, changing beneficiary designations, or making gifts.

Independent authority has a cost. Two agents acting separately can give inconsistent instructions to the same institution, and the principal loses the check that joint action provides. Whether the check is worth the friction depends on why two agents were named.

Is Each Co-Agent Liable for the Other?

Every agent is a fiduciary. New Jersey’s N.J.S.A. 46:2B-8.13 imposes a duty to act “solely for the benefit of the principal,” to keep “accurate books and records of all financial transactions,” and to account on request. Connecticut’s section 1-350m requires an agent to act in good faith, within the scope of authority, loyally, without conflicts of interest, and to “keep a record of all receipts, disbursements and transactions.” New York imposes parallel duties and, under General Obligations Law section 5-1509, lets the principal name a “monitor” with the right to “request, receive and compel the agent to provide a record of all receipts, disbursements and transactions,” a useful device when a parent wants one child to act and another to watch.

Liability for a co-agent’s misconduct is limited but not absent. Connecticut’s section 1-350j(c) provides that an agent “that does not participate in or conceal a breach of fiduciary duty committed by another agent” is not liable for the other’s actions, subject to a duty in the following subsection to notify the principal or take action when the agent knows of a breach. New Jersey’s statute is less specific, but an agent who knows a co-agent is misusing the principal’s funds and does nothing risks being found to have breached their own duty. A co-agent role is not honorary.

Why Do Banks Resist Co-Agent Powers of Attorney?

Because they have to read them. A bank presented with a two-agent document must determine whether the agents may act alone, and if they must act jointly, must obtain both signatures for every transaction and verify both identities. Many institutions require both agents to appear and sign signature cards regardless. Where the document is ambiguous, the bank’s counsel will often refuse rather than guess. Our article on what to do when a bank refuses a New Jersey power of attorney covers the statutory rights and the practical steps, and a clearly drafted co-agent clause removes the most common reason for refusal.

Can a Person Have Two Powers of Attorney?

Yes, and most people should. A financial power of attorney and a health care directive are separate documents with separate execution rules and often different agents, as explained in our article on the types of power of attorney in New Jersey. A person may also hold a general durable power of attorney and a limited power of attorney for a single transaction at the same time.

Two documents covering the same subject are a different matter. In New Jersey, under N.J.S.A. 46:2B-8.10, signing a new power of attorney does not revoke an earlier one “unless expressly so provided,” so a person who signs a second financial power of attorney naming a different child, without revoking the first, has two valid agents under two documents with no rule for how they interact. Every new power of attorney should state whether it revokes prior ones, and institutions holding the old document should be told.

A single power of attorney cannot have two principals. Spouses each sign their own, typically naming each other as primary agent and the same successor.

When Do Co-Agents Make Sense, and What Are the Alternatives?

Co-agents acting jointly make sense when the principal wants a genuine check on every transaction and the two agents are cooperative and geographically close. Co-agents acting independently make sense when the principal wants redundancy, so that a document does not fail because one agent is traveling or ill, and trusts both fully.

The more common and usually better structure is a single primary agent with one or more named successors. The primary agent acts alone and efficiently. If that person dies, resigns, or becomes incapacitated, the successor steps in without a new document or a court. New York’s and Connecticut’s statutes and New Jersey’s section 46:2B-8.7 all provide for successive agents. Where the principal wants oversight without shared authority, New York’s monitor provision provides it, and a New Jersey or Connecticut document can require the agent to send periodic accountings to a named family member by contract.

Whichever structure is chosen, the document should say expressly whether co-agents act jointly or severally, using the word “severally” if Connecticut law may apply; list the decisions, if any, that require all agents; provide what happens when an agent cannot act; name successors and the order in which they serve; and state whether the agents may delegate, which New Jersey allows only if the document specifically permits.

How Does a Co-Agent Power of Attorney End?

The document ends on the principal’s death in every state, on revocation by a competent principal, and on its own terms. Connecticut’s section 1-350i lists the events: death, incapacity if the power is not durable, revocation, a stated termination, accomplishment of the purpose, the death or incapacity of the agent where no successor is named, and termination by a court. The death or incapacity of one co-agent does not end the document in any of the three states; the remaining agents or the successors continue. The principal may also revoke one agent’s authority while leaving the other’s in place, and a court may remove an agent on application by a family member or other interested person, as Connecticut’s section 1-350o and New Jersey’s fiduciary removal statute provide.

Plan Well. Live Better.

Naming two agents feels safer than naming one, and drafted carelessly it is less safe than either. At Milvidskiy Law Group, we prepare powers of attorney that say exactly how the agents will work together and what happens when one cannot, so the document is honored when it is needed.
