What are the top malpractice risks for estate planning attorneys?

Estate planning is classified as a very high-risk practice area by most carriers, with premiums running 35% to 75% above baseline rates. The risk profile is driven by several factors unique to this practice area.

The delayed discovery of errors is the defining characteristic of estate planning malpractice. A drafting error in a will or trust may not be discovered until the client dies — potentially decades after the document was prepared. This creates an exceptionally long tail of exposure and makes maintaining continuous claims-made coverage with an unbroken retroactive date absolutely essential.

Drafting errors are the most common claim trigger. Ambiguous language in trust instruments, incorrect beneficiary designations, failure to properly fund trusts, errors in powers of appointment, and mistakes in tax allocation clauses can all redirect substantial wealth contrary to the client's intent.

Tax planning mistakes carry enormous exposure. Errors in generation-skipping transfer tax planning, improper use of valuation discounts, failure to account for estate tax portability, and mistakes in charitable remainder trust calculations can generate tax liabilities of hundreds of thousands or millions of dollars.

Failing to update documents is an increasingly common source of claims. Changes in tax law (such as the 2017 TCJA changes to estate tax exemptions), changes in family circumstances (divorce, births, deaths), and changes in asset composition all warrant document reviews. Attorneys who do not have systems to proactively contact clients about needed updates face significant exposure.

The intended beneficiary doctrine in many states allows non-clients (beneficiaries who were harmed by drafting errors) to sue the estate planning attorney. This expands the universe of potential claimants beyond the attorney-client relationship.

Prior acts coverage is critical in this practice area. If you switch carriers and your new policy has a retroactive date that does not extend back to the beginning of your estate planning practice, you could face uninsured claims from work performed years or decades ago.
