Why Your Estate Plan Needs a Stress Test

An effective estate plan can provide financial security for your loved ones, help ensure your assets are distributed as you intend and address potential tax consequences. But a plan that appears sound on paper may produce unintended results when unexpected circumstances unfold. Stress testing your estate plan can help you see whether it would still achieve your goals under a variety of scenarios.

How Does It Work?

A stress test is an assessment tool used to evaluate the performance of a system, plan, process or person under extreme, challenging or changing conditions (whether real or simulated). For example, a doctor may order a stress test to evaluate a patient's heart function during exercise. Or a bank may run simulations to see how adverse events or changes in interest rates or other market conditions would affect its financial health. In either case, stress testing can reveal potential risks that need to be addressed.

In estate planning, stress testing involves reviewing your plan and asking a series of "what if" questions to evaluate how it would perform in those scenarios. If the results don't align with your goals, you may want to modify your plan.

What Problems Can It Uncover?

Every estate plan — and every family — is different. So, stress-testing results will depend not only on the scenarios tested but also on your plan and circumstances. Examples of potential findings include:

Risky assumptions. You may, for instance, have developed your estate plan with the expectation that you'll live for many more years, giving your heirs time to mature or allowing your assets to grow significantly. Stress testing might reveal that if you die sooner, your plan could produce unexpected or undesirable consequences.

Perhaps assets would be distributed outright to your children before they'd be prepared to manage the funds on their own. One solution may be to set those assets aside in trust for your kids' benefit. Or a smaller-than-anticipated estate could cause certain estate plan provisions to produce different results than intended. Revisions may give your plan the flexibility to better achieve your goals.

Improper titling of assets. Many estate plans use revocable, or "living," trusts to help avoid probate and manage assets if you become incapacitated. But such a trust is effective only to the extent that you fully "fund" it — that is, transfer title to assets to the trust. A stress test may identify assets that aren't properly titled in the trust and, therefore, will be subject to probate or won't be under the trust's control if you become incapacitated.

Missing beneficiaries or fiduciaries. A stress test may reveal that you've failed to name a contingent beneficiary for, say, a retirement plan or an insurance policy. Or maybe you haven't identified a backup for a fiduciary (such as an executor, trustee or agent) in one or more important estate planning documents (such as your will, trusts or powers of attorney).

These gaps can disrupt your estate plan's operation if a beneficiary or fiduciary predeceases you. In the case of no contingent beneficiary, assets may pass in a way that's different from your wishes.

A stress test may also reveal that, say, your ex-spouse is still the beneficiary of a life insurance policy you'd forgotten about. Or it might show that someone you named as a fiduciary years ago is no longer the best person for the role.

Inflexible trust language. Based on the standards currently set for your trusts, would they achieve your goals? For example, a "maintenance" standard restricts distributions to the beneficiaries' most basic living expenses. If you want to provide more for them, consider raising the standard or even giving the trustee complete discretion to make distributions in accordance with your wishes.

Insufficient liquidity. Stress testing may reveal that a significant portion of your wealth is tied up in illiquid assets, such as real estate or closely held businesses. This may make it difficult to cover taxes and expenses, as well as to distribute these assets fairly among your heirs. For instance, if one child will inherit valuable real estate or a family business, your plan may need another source of funds to treat your other children fairly. Life insurance or other vehicles can provide such liquidity.

Who Can Help?

A stress test can't predict the future, but it can show how your estate plan may perform under potentially unanticipated circumstances. Contact your tax and estate planning advisors to discuss this and other strategies.

Project and Plan for Various Tax Scenarios

If the value of your estate exceeds federal or state exemption amounts, your heirs may lose a sizable chunk of your wealth to estate tax. For 2026, the federal gift and estate tax exemption is $15 million per individual, but some states have lower exemption amounts. The federal exemption is annually adjusted for inflation and has no expiration date. However, lawmakers could pass legislation in the future reducing it.

A stress test (see main article) can assess estate plan results based on the current, inflation-adjusted amount as well as on what would happen if the exemption is reduced before your death. It can also look at potential tax exposure based on different asset growth projections.

If estate tax is a concern, consider tax-efficient strategies to remove assets from your taxable estate. Or explore setting up an irrevocable life insurance trust to hold a policy whose proceeds could help cover estate taxes and other obligations. (If you own a life insurance policy outright, the proceeds will generally be included in your taxable estate.)
