How Does Power of Attorney Litigation Affect Your Estate Planning?

New York General Obligations Law section 5-1501 defines the duties of an agent under a power of attorney. The agent owes the principal a fiduciary duty that survives the principal's death if the power was durable, meaning decisions made after incapacity or death remain subject to scrutiny. Courts examine whether the agent acted within the scope of the document and whether transactions were consistent with the principal's known wishes. From a practitioner's perspective, heirs often face the difficult task of proving what the principal would have wanted when records are sparse or the agent's contemporaneous notes are missing.

Heirs may face claims from creditors or other beneficiaries if the agent depleted assets, made unauthorized gifts, or failed to preserve estate value. If the agent acted outside the scope of authority, heirs may need to recover those assets or defend against third-party claims that the estate was damaged. The burden falls on the estate or heirs to prove breach, but in New York practice, delayed documentation of unauthorized transactions often complicates recovery efforts in probate court or surrogate's court proceedings.

A surrogate's court has jurisdiction to hear disputes over power of attorney conduct and can order an accounting, remove the agent, and direct restitution. Heirs must file a petition and prove their standing, typically as beneficiaries or interested parties in the estate. The court examines whether the agent's transactions were authorized, whether records were maintained, and whether the principal's assets were protected. Seeking legal advice for real estate or other specific asset disputes early can preserve evidence and establish a clear record before the principal's death.

Before filing suit, heirs should demand a detailed accounting from the agent and preserve all documents related to the power of attorney and the principal's assets. If the agent refuses or provides incomplete information, that refusal strengthens a breach claim. In New York surrogate's court, a verified petition must describe the specific conduct at issue and the harm to the estate. Courts expect heirs to have attempted informal resolution or to demonstrate that the agent is uncooperative before formal litigation begins.

A well-drafted power of attorney should define the agent's powers narrowly, require written accounting at regular intervals, and specify whether the agent may delegate tasks or make gifts. Some principals appoint a successor agent or require the agent to report to a family member or advisor. Incorporating blended family estate planning principles can be especially important when the agent and the heirs have conflicting interests. Heirs benefit from knowing in advance whether the agent's authority includes investment management, real estate sales, or gifting, so disputes do not emerge unexpectedly after the principal's incapacity or death.

If you are an heir concerned about an agent's conduct, document all communications with the agent and request written confirmation of major decisions. Request copies of bank statements, investment accounts, and real estate records related to the principal's assets. If the principal is still living, encourage a formal review of the power of attorney and the agent's actions. These steps create a contemporaneous record that will be invaluable if litigation becomes necessary and will demonstrate to a court that you acted diligently to protect the estate.
