Estate Planning Is Not a Document. It Is a Discipline.

What Changes in Seven Years

Consider what happens in a typical family over seven to ten years. Children become adults. Grandchildren are born. A son or daughter gets married. Another gets divorced. The family business grows significantly, or is sold. Real estate is acquired in another state. A parent passes away. The family relocates. A child develops a disability that changes their long-term care needs. A family member starts a business. Another receives a significant inheritance from the other side of the family.

Each of these events has direct implications for the estate plan. A divorce changes beneficiary designations, trust provisions, and potentially the executor or trustee appointments. A business sale changes the asset mix from illiquid to liquid, which affects trust funding strategies and gift tax planning. A move to a different state may change which state's laws govern the estate, how assets are titled, and what the state estate tax exposure looks like.

The federal estate and gift tax exemption itself has changed meaningfully. Under the OBBBA signed in 2025, the exemption rose to $15 million per individual in 2026. Families whose plans were drafted when the exemption was $5 million or $11 million may have formula clauses in their trusts that now produce unintended results. A credit shelter trust formula designed to fund up to the exemption amount could now sweep $15 million into a trust that was originally intended to hold a much smaller portion of the estate, potentially leaving the surviving spouse's share underfunded.

Very few of these changes trigger an automatic review. The family must initiate it. And without a discipline of regular review, the changes accumulate silently until a transition event exposes every gap at once.

The Most Expensive Mistakes Are Coordination Failures

The most costly estate planning mistakes are rarely drafting errors. The attorney who wrote the original documents probably did competent work. The mistakes happen afterward, in the gap between what the documents say and what the family actually does.

The trust that was never funded is the most common example. A revocable living trust is only effective if the family's assets are retitled into the trust. If the trust exists but the bank accounts, brokerage accounts, and real estate are still in the individual's name, the trust does not control those assets at death. The family may end up in probate despite having a trust, simply because no one completed the funding process after the documents were signed.

Outdated beneficiary designations are another persistent problem. Retirement accounts, life insurance policies, and certain investment accounts pass directly to the named beneficiary regardless of what the will or trust says. A beneficiary designation that was set up twenty years ago and never updated after a divorce will send assets to the ex-spouse. The will does not override it. The trust does not override it. The beneficiary form controls.

Missed annual exclusion gifting is a subtler but significant failure. The annual gift exclusion allows each person to give up to a set amount per year per recipient without using any of their lifetime exemption. For families with multiple children and grandchildren, a disciplined annual gifting program can transfer substantial wealth over time without estate tax consequences. But it requires someone to track it, coordinate it, and execute it every year. When no one does, the opportunity simply passes.

These are not exotic problems. They are maintenance failures. And they are avoidable with a regular review process.

The Annual Review Discipline

We review estate documents with our clients at least once a year. Not because we expect the plan to change every year, but because the review itself creates the awareness that catches the changes that do matter.

The annual review typically covers several areas. First, a check of all beneficiary designations across retirement accounts, life insurance, and transfer-on-death accounts. These should match the current estate plan and reflect the family's current wishes. Second, a review of trust funding. Are all assets that should be held in the trust actually titled in the trust? Have new accounts been opened that need to be retitled? Third, a review of any life changes since the last review. Births, deaths, marriages, divorces, relocations, business transactions, and significant changes in asset values all warrant a fresh look at the plan.

Fourth, a review of the current tax rules. When the exemption amounts change, when the tax rates change, or when new legislation creates planning opportunities or risks, the estate plan should be evaluated in that new context. The OBBBA raised the exemption to $15 million, but it also introduced new provisions that may affect how certain trusts are taxed. Families whose plans have not been reviewed since the legislation passed may be missing opportunities or carrying risks they are not aware of.

The review is a coordination exercise between the wealth advisor, the estate attorney, and the CPA. The advisor brings the financial context. The attorney evaluates the legal documents. The CPA provides the tax perspective. When all three are in the room at the same time, looking at the same facts, the gaps become visible.

Estate Planning as a Living Framework

The shift in mindset is simple but important. An estate plan is not a completed project. It is a living framework that should be maintained with the same discipline applied to the assets it governs.

Just as a portfolio is reviewed regularly, rebalanced when conditions change, and adjusted when the family's needs evolve, the estate plan should be treated as an active part of the financial strategy rather than a static document.

Certain events should trigger an immediate review outside the annual cycle: a birth or adoption, a death, a marriage or divorce, the sale or acquisition of a business, a significant inheritance, a move to a new state, a major change in the tax code, or a significant change in net worth. When these events occur, the review should not wait for the annual meeting.

The cost of maintaining an estate plan with this level of discipline is modest compared to the cost of discovering, at the worst possible moment, that the plan does not work as intended. The families that treat estate planning as an ongoing practice rather than a one-time event are the ones whose plans actually do what they were designed to do.
