Professional Responsibility in Estate Planning Practice
The Model Rules as tested by long time horizons, family dynamics, joint representation, and duties to beneficiaries
Rule 1.1 in Estate Planning Has a Specific Tax Dimension
The duty of competence in estate planning is not a static obligation met once by adequate law school education. It is an ongoing obligation to monitor legislative, regulatory, and administrative developments in an area of law that changes with each Congress and each tax year. An estate planning attorney whose knowledge of the federal estate tax exemption reflects the law three years ago may provide advice that is wrong by millions of dollars.
An attorney who uses AI to orient their research, then verifies the AI's output against current IRS publications, current Treasury regulations, and current state statutes, is meeting the competence standard. An attorney who relies on AI output without verification is not — regardless of how authoritative the AI's response appears.
Confidentiality and AI tools: Estate planning clients share extraordinarily sensitive information — net worth, family dynamics, concerns about specific beneficiaries, the family tensions that shape every planning decision. The confidentiality obligation shapes which AI tools can be used and how. A public AI tool into which the attorney enters client-specific information may process and potentially retain that information in ways inconsistent with Rule 1.6. Evaluate any AI tool's data practices before entering client information.
Conflicts in Estate Planning — More Complex Than Most Practice Areas
Estate planning routinely involves joint representation of multiple parties with potentially diverging interests. Joint representation of spouses is the most common conflict scenario. Spouses present as a unit — they want to protect each other and their children. In practice, their interests may diverge: in the amount of property control the surviving spouse retains, in the treatment of children from prior relationships, in the allocation of tax burdens. The attorney must assess at the outset whether joint representation is appropriate, obtain informed consent from both spouses, and establish a clear understanding of how confidences will be handled if a conflict develops.
Duties to Third Parties
Estate planning creates duties that extend beyond the direct client. The intended beneficiary doctrine — recognized in many jurisdictions — allows a will beneficiary to sue the drafting attorney when the attorney's negligence caused the beneficiary to receive less than the testator intended. Beneficiaries were not parties to the attorney-client relationship. They had no way to protect themselves from drafting errors. An AI drafting error in a trust distribution provision that goes undetected may harm beneficiaries who could sue the attorney who drafted it.
The practical implication: The verification obligation in estate planning protects not just the client but the beneficiaries whose interests the documents are designed to serve. This is a broader duty than most attorneys recognize when they first integrate AI tools into their drafting workflow.
