Financial advisors and estate planners are often the first to recognize when a client’s estate plan is no longer aligned with their financial reality, even when there are no obvious warning signs.

Unlike a static legal document, a client’s balance sheet, tax exposure and family dynamics evolve continuously. As a result, estate plan reviews should be treated as a core advisory function, not a one-time legal exercise.

Estate Plans Aren’t a Time Capsule

Clients often assume their estate plan is complete once documents are signed. Advisors know that as portfolios grow and change, the assumptions underlying those plans quickly become outdated.

The hesitation to revisit the land of death and taxes is understandable. Drafting an estate plan requires significant time, emotional energy and legal fees, and there’s a natural human tendency to file it away and declare victory. But the moment the ink dries, the facts on which the plan was built begin to change.

The mechanics of a well-drafted trust or will don’t expire, but the assumptions baked into those documents do:

These aren’t hypothetical risks. They occur in real families with distressing regularity.

In my experience, the families who avoid the most painful estate administration problems aren’t necessarily those with the most sophisticated planning documents. They’re the families who treat their estate plan as a living document and review it regularly with counsel and whenever a significant life event occurs.

The Business Sale

Few events recalibrate an estate plan as dramatically and as quickly as the sale of a closely held business. Consider a business owner, David, age 60, who built a manufacturing company over 30 years. David has a revocable trust, a pour-over will and a modest life insurance policy. 

His estate plan was drafted when the company was worth $3 million, and the rest of his assets totaled another $2 million. At that time, his $5 million estate comfortably fit beneath the federal exemption; estate tax wasn’t a driving concern and his plan focused primarily on succession and probate avoidance.

David sold the company for $18 million. After taxes and deal costs, he deposited approximately $13 million in liquidity into his investment accounts. His estate tripled, almost overnight, to roughly $15 million. His existing estate plan, drafted for a $5 million estate, had no provisions to address a possible taxable estate or to provide his children with creditor and divorce protection.

From an advisory perspective, this is a clear inflection point. David’s pre-sale estate plan isn’t wrong; it’s simply obsolete. A post-liquidity review should address the structure of new accounts, trust funding, gifting strategy, charitable vehicles such as charitable remainder trusts or donor-advised funds and updated fiduciary designations that reflect David’s new financial reality.

Equally important, many of these planning opportunities are most effective if addressed before the transaction closes. This is where advisors play a critical role. Pre-transaction planning is often the difference between missed opportunities and optimized outcomes. Coordinating with estate planning counsel in advance can allow for more tax-efficient structuring, strategic gifting, and the implementation of charitable planning vehicles.

Waiting until “things settle down” after a sale is one of the most common and costly mistakes in high-net-worth estate planning.  The period immediately before and after a liquidity event is when estate planning is most impactful, and advisors are best positioned to ensure clients take advantage of that window.

The Fiduciary Fitness Problem

When an estate plan is first drafted, the choice of successor trustee, personal representative, guardians for minor children and an agent under a financial power of attorney typically reflects the trusted people in a client’s life at that moment: a sibling, college friend or business partner. Those appointments often remain unchanged for years, even decades, while the actual fitness of those individuals for the roles evolves considerably. This is a gap advisors are particularly well suited to identify.

Consider a client who named her older brother as successor trustee in 2008. He was sharp, organized and lived nearby. By 2025, he had been diagnosed with early-stage cognitive decline, lived across the country and hadn’t managed his own assets for years.  

Under the terms of the trust, he remains the designated first successor trustee. Unless the trust instrument includes a mechanism for voluntary resignation or removal, and unless the client reviews her plan and updates the appointment, her estate will be administered by a fiduciary who is neither able nor well-positioned to serve.

A similar dynamic applies to guardianship decisions. Advisors often see clients who selected guardians based on shared values when children were young, but haven’t revisited those decisions as circumstances changed. As children approach adolescence, practical considerations, such as geography, school continuity and social environment, may make the original choice less appropriate.

Fiduciary designations aren’t “set and forget” decisions; they’re ongoing risk factors. A thoughtful estate plan review examines not just who’s named but whether each individual remains an appropriate choice given their current health, location, financial sophistication and relationship dynamics.

Crossing State Lines

Client relocations are a common, often overlooked trigger of estate plan misalignment. Advisors are frequently the ones navigating the implications when a move between states may carry unintended planning consequences.

Moves between separate property states (such as Illinois or Oregon) and community property states (such as Arizona or California) can materially affect how assets are characterized and ultimately taxed.

For example, a married couple who spent decades in a separate property state and then retire to Arizona may have accumulated assets that lack the community property character that entitles surviving spouses to a full stepped-up income tax basis on both halves of jointly appreciated property. Conversely, a couple moving from Arizona to a separate property state may hold assets with community property origins that deserve careful documentation to preserve their tax character going forward.

Beyond tax character, state-specific rules govern homestead protections, creditor exemptions and the validity of certain estate-planning instruments. A trust drafted under Arizona law for an Arizona resident isn’t automatically optimal for a new Oregon resident. A plan review after any interstate move is not optional; it is essential.

Asset Titling and Beneficiary Designations

Even a perfectly drafted estate plan can be rendered ineffective by a single overlooked administrative detail: an asset that never made it into the trust. There’s a common assumption that once the trust is signed, no further action is required. In reality, the trust governs only assets properly titled in its name or directed to it through legally valid beneficiary designations. An investment account left in an individual name, or a piece of real estate never deeded to the trust, passes outside the trust’s terms entirely and may require full probate proceedings.

Beneficiary designations present a parallel and equally serious risk. Life insurance proceeds, individual retirement accounts, Internal Revenue Code Section 401(k) accounts and payable-on-death bank accounts all pass directly to the named beneficiary by contract, overriding whatever the trust or will provides. If a client’s IRA names a deceased parent as the primary beneficiary with no contingent beneficiary identified, the account may be treated as part of the probate estate rather than passing according to the trust. If a brokerage account carries a transfer-on-death designation to one child, and the trust divides assets equally among three, the designated child receives the full account regardless of the trust’s intent.

These issues are rarely the result of poor drafting. They’re breakdowns in coordination. Because advisors maintain visibility into account structure, titling and beneficiary designations across the client’s balance sheet, they’re the ones who spot when things fall out of alignment.

That misalignment rarely happens all at once. Every major life event (for example, a new home purchase, a business acquisition, a financial account rollover, a divorce or a death in the family) is an opportunity for an asset to fall out of alignment with the estate plan. Routine reviews of account titling and beneficiary designations aren’t housekeeping tasks; they’re the mechanics that make an estate plan actually work.

The Cost of Inaction

The families who suffer the most painful estate administration complications aren’t, in my experience, those who did no planning at all. They’re the families who did careful planning 20 years ago and never looked at it again. The out-of-date trust, the unfunded account, the deceased trustee and the stale beneficiary designation are avoidable problems. They compound each other in ways that generate probate proceedings, family disputes, unnecessary tax exposure and the very outcome that every estate plan is designed to prevent.

For advisors, these aren’t theoretical risks. They’re patterns that emerge when estate plans are treated as fixed documents rather than evolving components of a client’s financial strategy. These patterns are also some of the clearest opportunities to prompt clients to revisit and update their estate plans before those risks materialize.

Regular coordination with estate planning counsel, along with periodic reviews of asset titling, beneficiary designations and fiduciary appointments, is the most effective way to ensure a plan drafted for a client’s past circumstances continues to function as intended. The cost of that review is minimal compared to the financial and administrative consequences of getting it wrong.
