Estate planning has an unusual failure mode: the work gets done conscientiously, once — and then sits untouched while everything it was designed to govern keeps changing. Families grow and fracture. Net worth compounds. Laws move. The result is a plan that is legally valid but factually obsolete, which can be nearly as problematic as no plan at all.

Here's how to tell whether your documents have drifted from your life, and a practical framework for fixing it.

The Triggers: When a Review Is Overdue

A useful rule of thumb: review your estate plan every three to five years, and immediately upon any of the following:

  • Family changes. Marriage, divorce, remarriage, births, deaths, estrangements, a child reaching adulthood, or a beneficiary developing special needs or creditor problems. Documents drafted when your children were minors — with guardianship provisions and trusts that terminate at arbitrary ages — often fit poorly once those children are adults with families of their own.
  • Financial changes. A business sale, an inheritance, significant equity compensation, real estate purchases (especially in other states), or simply years of growth that moved your estate into a different planning tier than when the documents were drafted.
  • Geographic changes. Moving between states can affect the validity mechanics of documents, property rights (community property vs. common law states), and state-level estate or inheritance tax exposure.
  • Law changes. Federal transfer tax law has moved repeatedly over the past two decades. Most recently, 2025 legislation set the federal estate and gift tax exemption at $15 million per person beginning in 2026 (indexed for inflation thereafter), replacing a scheduled reduction to roughly half that level. Plans built around older exemption assumptions — particularly formula-based trust provisions drafted when exemptions were far lower — can now produce unintended results, such as overfunding certain trusts at the expense of a surviving spouse's flexibility.
  • Fiduciary changes. The people you named — executors, trustees, guardians, agents under powers of attorney and healthcare directives — may have aged, moved, died, or drifted out of your life. The right person fifteen years ago is not automatically the right person today.

The Quiet Problem: Beneficiary Designations

Here is the piece many people overlook: for many households, a substantial portion of wealth — retirement accounts, life insurance, annuities, transfer-on-death accounts — passes by beneficiary designation, outside the will entirely. A carefully drafted will does not override an outdated 401(k) beneficiary form. Ex-spouses, deceased parents, and long-outgrown decisions can remain on these forms for years. An estate plan review that includes pulling current beneficiary designations on every account and policy helps address this gap.

A Practical Review Framework

  • Step 1 — Inventory. List every document (will, trusts, powers of attorney, healthcare directives) with dates, and every asset with how it's titled and who its beneficiaries are.
  • Step 2 — Check alignment. Does each asset flow where you think it does? Titling and designations override wills; assets that were not retitled into a trust may not be governed by it.
  • Step 3 — Reconfirm the people. For each fiduciary and beneficiary: is this still the right choice, and are the backups still viable?
  • Step 4 — Test against current law and current net worth. Formula clauses, state tax exposure, and basis planning (the step-up in cost basis at death has grown in relative importance now that fewer estates face federal estate tax) all deserve a fresh look at today's numbers.
  • Step 5 — Engage the professionals. Estate documents are legal instruments — updates belong with a qualified estate planning attorney, coordinated with your tax and financial advisors so the legal structure, the tax analysis, and the financial plan agree with each other.

The Cost of Drift

Outdated plans produce concrete problems: assets passing to unintended people, avoidable taxes and administrative costs, family conflict over ambiguous provisions, and courts filling gaps you could have filled yourself. The fix is not dramatic — it's a periodic review habit, the same discipline applied to any other important system.

Frequently Asked Questions

How often should an estate plan be reviewed?

Every three to five years as a baseline, and immediately after major family, financial, geographic, or legal changes.

Do I need to redo everything, or can documents be amended?

Often documents can be updated through codicils or trust amendments rather than full restatements — a determination your estate planning attorney makes based on the scope of changes.

What is the federal estate tax exemption right now?

$15 million per individual beginning in 2026 (up to $30 million for a married couple with portability), with inflation indexing starting in 2027. State-level estate and inheritance taxes are separate and vary.

My estate is nowhere near the exemption. Do I still need a plan?

Yes — most of estate planning (incapacity documents, guardianship, probate avoidance, beneficiary coordination, family clarity) has nothing to do with the federal estate tax.
