Connecticut Power of Attorney Laws: Durable, Medical, and Financial POA (2026)

Connecticut adopted the Connecticut Uniform Power of Attorney Act (UPOAA) effective October 1, 2016, replacing the old statutory short-form framework with a modern, comprehensive scheme codified at Conn. Gen. Stat. 1-350 through 1-353b. Under that framework a financial power of attorney is durable by default, meaning the agent's authority survives the principal's incapacity unless the document explicitly provides otherwise. Execution requires the principal's signature and two adult witnesses under Conn. Gen. Stat. 1-350d; notarization is not required for validity, but acknowledgment before a notary public creates a statutory presumption that the signature is genuine under Conn. Gen. Stat. 1-350r and is strongly recommended because third parties may decline a POA that is not notarized. Health care decisions are handled through a completely separate document, the appointment of a health care representative, governed by Conn. Gen. Stat. 19a-575 et seq..

What a Power of Attorney Does in Connecticut

A power of attorney is a written document in which one person, the principal, grants another person, the agent (also called attorney-in-fact), authority to act on the principal's behalf. In Connecticut the authority can cover a single transaction or virtually all financial and legal affairs. Whatever scope the principal chooses, the agent steps into the principal's shoes for covered matters and is bound by strict fiduciary duties.

Connecticut draws a firm line between financial authority and health care authority. A financial POA under the UPOAA framework does not give the agent any power to make medical decisions. For health care, Connecticut uses a separate statutory instrument, the appointment of a health care representative under Conn. Gen. Stat. 19a-575. Many residents execute both documents as part of a complete incapacity plan.

A POA also ends at the principal's death. From that moment, only the executor named in a will, or an administrator appointed by the probate court in an intestate estate, has legal authority to manage and distribute assets. An agent who continues to act after learning of the principal's death may face civil and criminal liability.

Durable Power of Attorney in Connecticut

Durability is the feature that makes a POA useful for long-term planning. Without it, the agent's authority terminates the instant the principal becomes incapacitated, defeating the primary purpose of the document.

Under Conn. Gen. Stat. 1-350c, every power of attorney created on or after October 1, 2016, is durable by default. The document does not need to contain any special "durable" language. Durability is presumed. A principal who wants a non-durable POA, one that terminates on incapacity, must include an express provision to that effect.

Connecticut also permits springing POAs that become effective only upon a specified future event, typically a written determination of the principal's incapacity. If the document does not specify how incapacity is to be determined, the default under Conn. Gen. Stat. 1-350h(c) is a written determination by two independent physicians, or by a judge if the type of incapacity involved falls under the judicial definition in section 1-350a(5)(B).

The UPOAA definition of "incapacity" means the inability of an individual, even with appropriate assistance, to manage their affairs because a mental, emotional, or physical condition prevents them from receiving and evaluating information or making and communicating decisions. This is a functional rather than a purely medical standard.

How to Create a Valid Connecticut Power of Attorney

Connecticut imposes two formal requirements for a valid power of attorney under Conn. Gen. Stat. 1-350d, plus a third step that is strongly recommended in practice:

Signature. The principal must sign the document. If the principal is physically unable to sign, another individual may sign the principal's name in the principal's conscious physical presence at the principal's direction.

Two witnesses. The signing must be witnessed by two adults. The witnesses attest that the principal signed (or directed another to sign) and appeared to be of sound mind and acting voluntarily. Connecticut law does not permit the agent or any successor agent named in the document to serve as a witness.

Notarial acknowledgment (recommended, not required for validity). Under Conn. Gen. Stat. 1-350r, if the principal's signature is acknowledged before a notary public, a commissioner of the Superior Court, or another individual authorized by Connecticut law to take acknowledgments, the signature is presumed genuine when a person accepts the POA in good faith. Acknowledgment is not a validity requirement under Conn. Gen. Stat. 1-350d, but it is strongly recommended: third parties may decline a POA that lacks notarization, even though they may be legally obligated to accept a properly executed document.

Connecticut provides both a statutory short form and a long form POA at Conn. Gen. Stat. 1-352. These forms include all required components and are widely accepted. A POA that does not use the statutory form is still valid if it meets the execution requirements of Conn. Gen. Stat. 1-350d.

Under Conn. Gen. Stat. 1-350e, a POA executed in Connecticut on or after October 1, 2016, is valid if its execution complies with Conn. Gen. Stat. 1-350d. A POA executed before that date remains valid under the prior law.

What a Connecticut Agent Can and Cannot Do

The scope of an agent's authority is defined by the document. Connecticut's UPOAA lists categories of general authority including banking, real property, tangible personal property, stocks and bonds, business operations, insurance, government benefits, retirement plans, taxes, and more. The agent may exercise any category the document grants.

Certain sensitive powers, called "hot powers," require an express grant of authority in the POA document. Under Conn. Gen. Stat. 1-351, an agent may exercise the following powers only if the document explicitly authorizes them:

• Creating, amending, revoking, or terminating an inter vivos trust (Conn. Gen. Stat. 1-351(a)(1)).
• Making gifts on the principal's behalf (Conn. Gen. Stat. 1-351(a)(2)).
• Creating or changing rights of survivorship in property (Conn. Gen. Stat. 1-351(a)(3)).
• Creating or changing a beneficiary designation (Conn. Gen. Stat. 1-351(a)(4)).
• Waiving the principal's right to be a beneficiary of a joint and survivor annuity, including a survivor benefit under a retirement plan (Conn. Gen. Stat. 1-351(a)(5)).
• Exercising fiduciary powers that the principal has authority to delegate (Conn. Gen. Stat. 1-351(a)(6)).
• Disclaiming property, including a power of appointment (Conn. Gen. Stat. 1-351(a)(7)).
• Exercising all powers the principal may have over any digital device, digital asset, user account, and electronically stored information (Conn. Gen. Stat. 1-351(a)(8)).
• Acting with respect to any intellectual property interests of the principal, including copyrights, contracts for payments of royalties, and trademarks, in all ways as if the agent were the owner (Conn. Gen. Stat. 1-351(a)(9)).

Things an agent cannot do regardless of what the document says include making or changing the principal's will, voting in a public election on the principal's behalf, and making health care decisions (which require a separate health care representative appointment). An agent also cannot act contrary to the principal's reasonable expectations or, if those expectations are unknown, against the principal's best interests.

Under Conn. Gen. Stat. 1-350m, an agent who accepts appointment must act loyally for the principal's benefit, avoid conflicts of interest, act with due care, cooperate with the principal's health care representative, and keep complete records. The agent must keep the principal's property separate from the agent's own property.

Third-party acceptance. Under Conn. Gen. Stat. 1-350s, a person presented with an acknowledged POA must either accept it or request a certification, translation, or legal opinion within seven business days. If a certification or opinion is requested, the person must then accept within five business days of receiving it. A person who refuses without a permitted reason may be liable for damages and attorney's fees.

Health Care Representative and Living Will in Connecticut

Connecticut law separates financial authority from health care authority. A financial POA does not authorize any medical decision. Health care authority comes from two distinct instruments: the appointment of a health care representative and the living will (also called health care instructions), both governed by Conn. Gen. Stat. 19a-575 et seq.

Appointment of a health care representative (Conn. Gen. Stat. 19a-575). Any person 18 or older may appoint another adult to make health care decisions on their behalf when the principal lacks decision-making capacity. The appointment must be signed and dated by the principal in the presence of two adult witnesses who also sign. The person being appointed as representative may not act as a witness to the document. If the principal resides in a facility operated or licensed by the Department of Mental Health and Addiction Services, at least one witness must be unaffiliated with the facility and at least one must be a physician, advanced practice registered nurse, or licensed clinical psychologist with specialized training in treating mental illness. Notarization is not a statutory requirement for the appointment itself, though an optional self-proving witnesses' affidavit may be sworn before a notary under Conn. Gen. Stat. 19a-578.

Living will (Conn. Gen. Stat. 19a-575). A living will lets a person state specific instructions about end-of-life care and the use of life-sustaining treatment. It uses the same two-witness execution requirement as the health care representative appointment. A person may combine both documents in a single instrument under Conn. Gen. Stat. 19a-575a, which provides an optional combined form.

The health care representative has authority to make any decision about the principal's care, treatment, or placement that the principal would have the right to make if capable, subject to any instructions in the living will. The representative must follow the principal's expressed wishes and, when those wishes are unknown, act in the principal's best interests.

Revoking or Ending a Connecticut Power of Attorney

A principal who retains capacity may revoke a financial POA at any time and in any manner that communicates the intent to revoke. Written notice delivered to the agent is the safest approach. The principal should also notify any financial institution, government agency, or other third party that has relied on the document.

Under Connecticut's UPOAA, a financial POA terminates when:

• The principal revokes it.
• The principal dies.
• A court terminates the agent's authority or appoints a conservator who does so.
• The document itself specifies an expiration date or a terminating event.
• The agent dies, becomes incapacitated, or resigns and the document does not name a successor.
• A legal action for dissolution or annulment of the agent's marriage to the principal is filed, unless the document provides otherwise.

If the POA authorized real-property transactions and was recorded in the land records, revocation should also be recorded with the town clerk of the municipality where the original POA was recorded, to protect against third parties who might otherwise rely on the recorded document.

To revoke a health care representative appointment, Conn. Gen. Stat. 19a-575a(b) requires a written revocation signed by the declarant and two witnesses. A living will (the health care instructions portion) may be revoked at any time and in any manner under Conn. Gen. Stat. 19a-579a, including a verbal statement. Revocation of the appointment is effective when the signed writing is communicated to the health care provider, who must make it part of the medical record.

A principal should review POA documents after major life events such as divorce, a move to another state, or a significant change in the relationship with the named agent.
