§ I
The Penhallow Method

The 7-Layer
Dynasty Audit

A structured, repeatable diagnostic instrument — not a checklist — applied across more than 1,800 engagements to map the architecture of generational estates and locate the structural inefficiencies that quietly erode them.

§ II — Anatomy of the Instrument

Seven Diagnostic Passes, Sequenced for Resolution

Each engagement is conducted through seven distinct, sequential diagnostic layers. The audit is not a form — it is a deliberate, layered examination of the structures that already exist, the exposures that have accumulated, and the architecture required for the next generation.

  1. 01

    Asset Inventory & Title Reconstitution

    A granular reconstitution of every titled and untitled interest — operating entities, partnership units, real property, retirement accounts, digital assets, and beneficial interests — mapped against current titling, beneficiary designations, and jurisdictional situs.

  2. 02

    Transfer-Tax Exposure Modeling

    Forward projection of federal estate, gift, and generation-skipping transfer-tax exposure across two planning horizons, including scheduled exemption sunsets, state-level decoupled taxes, and GST allocation shortfalls.

  3. 03

    Entity Architecture Review

    A forensic read of the existing entity stack — LLCs, FLPs, GRATs, IDGTs, dynasty trusts, charitable structures — assessed for drafting integrity, valuation defensibility, and alignment with the family's stated objectives.

  4. 04

    Trust Sequencing & Distribution Waterfall

    Tracing of the actual administration path: trustee succession, distribution standards, decanting feasibility, and the precise order in which assets would reach each generation under current documents.

  5. 05

    Beneficiary Alignment & Class Integrity

    Reconciliation of named beneficiaries, remaindermen, and discretionary classes against the principal's intent — identifying drift, omission, and unintended inclusions created by unupdated instruments.

  6. 06

    Family Governance & Decision Architecture

    Examination of the human infrastructure: family constitutions, governance councils, succession protocols, and the documented procedures by which the next generation will inherit not merely wealth but stewardship.

  7. 07

    Contingency Resilience & Continuity

    Stress-testing the entire structure against incapacity, premature death, jurisdictional challenge, creditor exposure, and the dissolution of any single holding entity — the questions that only surface at the moment of crisis.

The Audit, in Numbers

§ IV — Calibrated, Not Generic

An Instrument Built for Estates of a Certain Scale

The 7-Layer Dynasty Audit™ is not designed for the modest estate that a single will and a revocable trust can comfortably resolve. It is engineered for principals whose holdings — operating businesses, concentrated equities, multi-jurisdictional real estate, legacy charitable structures — have accumulated a complexity that template drafting cannot honestly address.

Our median client carries $14.3 million in administered assets; the principal is fifty-eight; the structure has typically been amended, in places, over three decades. By the time such a family reaches us, the document stack has thickened faster than the underlying plan has been reconsidered. Inconsistencies accumulate between the LLC operating agreement drafted in 2003, the trust restated in 2011, and the beneficiary forms updated only in 2019. The Dynasty Audit exists to surface exactly these tensions — and to convert them, systematically, into a coherent architecture.

We do not accept every inquiry. The audit is calibrated for families whose estates warrant diagnostic-grade review; it is not the appropriate instrument for a $2 million book of investments held in a single revocable trust. If, after a confidential intake, we conclude that the Penhallow method is not the right fit, we will say so plainly and refer you to a firm whose scale matches your requirements.

"The audit is not the deliverable. The audit is the diagnostic that makes a deliverable possible."

§ V — Authority to Publish

The Credentials Behind the Method

A proprietary framework is only authoritative when it is authored by a firm with the standing to defend it. The Penhallow firm's authority rests on the following credentials and external validations.

  1. ACTEC Fellowship Since 2011

    Margaret Penhallow has been a Fellow of the American College of Trust and Estate Counsel since 2011 — an invitation-only membership limited to the leading trust and estate attorneys in the United States.

  2. Four Attorneys Admitted to the U.S. Tax Court Bar

    Penhallow's litigation-adjacent tax practice is staffed by four attorneys with direct admission to the United States Tax Court — a credential that informs the firm's drafting posture at the most technical tier.

  3. 14 Peer-Reviewed Articles in Trusts & Estates Quarterly

    Since 2017, the firm has published fourteen peer-reviewed articles in Trusts & Estates Quarterly, contributing to the technical literature of the discipline its practitioners serve.

  4. Private Wealth Magazine — Top 25 Boutique Firm, 2022 & 2024

    Penhallow was named to Private Wealth Magazine's "Top 25 Boutique Trusts & Estates Firms" in both 2022 and 2024 — one of a small number of firms recognized in consecutive cycles.

§ VI — The Engagement Arc

From First Call to Delivered Findings

The Dynasty Audit proceeds through four deliberate stages, each terminating in a written deliverable before the next is initiated.

  1. I

    Concierge Intake

    A discreet, unrecorded conversation with the firm's concierge — typically forty-five minutes — to establish whether the engagement warrants the Penhallow method. No documents are required at this stage.

    45 minutes  ·  by telephone or in person
  2. II

    Engagement Letter & Document Assembly

    A fixed-fee engagement letter is issued for the audit cycle. The firm's intake team works with your existing advisors to assemble the document stack — typically four to six weeks.

    4–6 weeks  ·  fixed fee
  3. III

    Diagnostic Cycle

    The seven layers are conducted in sequence by a senior estate strategist, supported by an in-house tax analyst. Findings are documented as they emerge; nothing is held for a single terminal reveal.

    8–12 weeks  ·  sequenced
  4. IV

    Findings Presentation

    A bound written report is delivered, followed by a private presentation at the firm's Boston or Greenwich office. The findings are yours to keep, irrespective of any subsequent engagement.

    Half-day  ·  principal + spouse

The audit typically precedes a multi-year implementation engagement — but it is not contingent on one.
