Unintended Mistakes in Estate Planning: How to Protect Your Family and Your Legacy

Estate planning is about more than deciding who inherits your property. It is about protecting your loved ones, preserving your assets, and ensuring your wishes are carried out after your death. Unfortunately, even well-intentioned families can make estate planning mistakes that lead to unintended consequences, family disputes, and unnecessary financial hardship.

At Beck, Lenox & Stolzer Estate Planning & Elder Law, LLC, we believe education is an important part of helping families plan for the future. Our St. Charles estate planning attorneys in Missouri help individuals and families understand the importance of creating a comprehensive estate plan that reflects their goals and protects the people they care about.

As discussed in The News-Enterprise article, “Advice for Avoiding Unintended Issues in Estate Planning”, seemingly small decisions can have significant consequences. Signing a document without understanding its legal impact, failing to execute a will properly, or assuming an estate plan will accomplish something it does not specify can all create problems for your heirs.

Understanding common estate planning mistakes can help you avoid unnecessary complications and give your family greater peace of mind.

1. Leaving Everything to a Surviving Spouse in a Blended Family

One of the most common unintended estate planning mistakes involves blended families. When spouses have children from previous relationships, leaving the entire estate to the surviving spouse may unintentionally disinherit the deceased spouse’s children.

During a parent’s lifetime, children may have a positive relationship with their stepparent and trust that their parent’s wishes will be respected. However, after the first spouse dies, circumstances can change. The surviving spouse may remarry, revise their estate plan, or decide to leave most or all of their assets to their own biological children.

Even when no one intends to cause harm, the result can be that the deceased spouse’s children receive little or nothing from their parent’s estate. These situations can create lasting family conflict.

A carefully structured revocable living trust may help blended families address this concern. Depending on how the trust is drafted and funded, it can provide for the surviving spouse during their lifetime while preserving designated assets for children or other beneficiaries after the surviving spouse’s death.

The trust can be designed to balance the surviving spouse’s financial needs with the first spouse’s wishes for their children. The appropriate provisions depend on the family’s circumstances, assets, and goals.

For blended families in St. Charles and throughout Missouri, working with an experienced estate planning attorney can help prevent misunderstandings and reduce the risk of unintended disinheritance.

2. Failing to Coordinate Estate Plans Between Spouses

Another common mistake occurs when married couples create separate wills without considering how the documents work together.

For example, spouses may each name the other as the primary beneficiary, assuming their assets will ultimately pass to all their children or other intended beneficiaries. However, once the first spouse dies and the surviving spouse inherits the property, the surviving spouse may have the legal ability to change their estate plan.

If the surviving spouse later changes beneficiaries, remarries, or develops different priorities, the original plan for distributing the couple’s combined assets may no longer be followed.

Couples should discuss their wishes together and consider what should happen after the first spouse’s death and after the surviving spouse’s death. This includes deciding whether assets should pass outright to the surviving spouse, be divided among children, or remain in trust under specific conditions.

A coordinated estate plan can help ensure that both spouses understand how their property will be distributed and what flexibility the survivor will have. Depending on the circumstances, wills, revocable living trusts, or other estate planning tools may be appropriate.

The goal is to create a plan that reflects the couple’s shared intentions rather than relying on assumptions about what will happen later.

3. Assuming Your Spouse Will Inherit Everything if You Die Without a Will

Many people believe that their spouse automatically inherits everything if they die without a last will and testament. In Missouri, that is not always true.

When someone dies without a valid will, they are said to have died intestate. Missouri’s intestate succession laws determine who inherits the deceased person’s probate property. The outcome depends on the surviving family members and the circumstances of the estate.

For example, under Missouri law, if the deceased person leaves a surviving spouse and descendants who are also descendants of that spouse, the spouse generally receives the first $20,000 of the estate plus one-half of the remaining balance, with the descendants receiving the other half. Different rules apply when the deceased person has descendants who are not also descendants of the surviving spouse.

These rules can produce results that differ significantly from what a family expected. They may also create complications when family relationships are strained or when the surviving spouse and children have different financial needs.

Creating a valid will allows you to express your wishes for the distribution of your probate property, subject to applicable law. A broader estate plan can also address assets that pass through beneficiary designations, joint ownership, and trusts.

Do not assume Missouri’s default inheritance rules will match your wishes. An estate planning attorney can explain how these laws apply to your family and help you develop a plan that reflects your intentions.

4. Failing to Plan for an Heir With a Disability

An inheritance can create unexpected problems for a beneficiary who has a disability and receives means-tested government benefits.

Certain benefits, including Supplemental Security Income (SSI) and Medicaid, have financial eligibility requirements. If a beneficiary receives an inheritance outright, the additional assets may affect eligibility for some benefits, depending on the program and the beneficiary’s circumstances.

This can put families in a difficult position. They want to provide financial support for a loved one, but an inheritance that is not structured appropriately could jeopardize benefits the individual relies on for healthcare, housing, or other essential needs.

A special needs trust, when properly designed and administered, may allow assets to be used for a beneficiary’s supplemental needs while helping preserve eligibility for certain means-tested benefits. The trust’s terms, funding, and administration must be tailored to the beneficiary and the applicable program rules.

Planning ahead is especially important because no one can predict with certainty whether a child, grandchild, or other loved one will develop a disability or need public benefits in the future.

An estate planning attorney can help you evaluate whether special needs planning should be part of your estate plan and determine which provisions may be appropriate for your family.

5. Signing Estate Planning Documents Without Understanding Their Impact

Estate planning documents are legal instruments, and the wording matters. A will or trust may not accomplish what you expect if it is improperly drafted, executed incorrectly, or inconsistent with your other arrangements.

For example, a will may be invalid if it does not satisfy Missouri’s legal execution requirements. A trust may not accomplish its intended purpose if assets that should be held in the trust are never transferred into it. Beneficiary designations on retirement accounts and life insurance policies may also direct assets to people other than those named in a will.

Other mistakes can arise when people use outdated documents, rely on generic forms without understanding their limitations, or fail to update their plans after marriage, divorce, the birth of a child, a death in the family, or a significant financial change.

To reduce these risks, review your estate plan periodically and whenever an important life event occurs. Make sure your documents are properly executed, your beneficiary designations are coordinated with your overall plan, and any trust is funded as intended.

Professional guidance can help you identify gaps and understand the potential consequences of your decisions before they become problems for your loved ones.

Avoiding Estate Planning Mistakes Starts With the Right Plan

No estate plan can anticipate every possible future event. However, careful planning can address many foreseeable issues and reduce the likelihood of unintended consequences.

An effective estate plan should reflect your family structure, financial circumstances, and personal priorities. It should also account for changes in your life and the possibility that your beneficiaries may have different needs in the future.

Whether you have a blended family, want to protect a child with a disability, or simply want to ensure your property passes according to your wishes, taking the time to plan can help reduce uncertainty and prevent avoidable disputes.

Frequently Asked Questions About Estate Planning Mistakes

1. What are the most common unintended mistakes in estate planning?

Common mistakes include leaving all assets to a surviving spouse without considering children from previous relationships, failing to coordinate estate plans between spouses, dying without a valid will, overlooking special needs planning, and neglecting to update beneficiary designations or fund a trust properly. These mistakes can lead to unintended distributions, family disputes, or financial complications for heirs.

2. How can I protect my children from a previous marriage in my estate plan?

A revocable living trust or another carefully designed estate planning arrangement may help provide for your surviving spouse while preserving assets for your children. The appropriate approach depends on your family’s needs, the ownership of your assets, and how much flexibility you want the surviving spouse to have.

3. Does my spouse automatically inherit everything if I die without a will in Missouri?

No. Missouri’s intestate succession laws determine how probate property is distributed when someone dies without a valid will. The surviving spouse’s share depends on whether the deceased person has descendants and whether those descendants are also descendants of the surviving spouse. Creating a will and coordinating your broader estate plan can help you make your wishes clear.

4. Can an inheritance affect a loved one’s disability benefits?

Yes. An inheritance received directly by someone who receives means-tested benefits may affect eligibility for certain programs, including SSI and Medicaid. A properly structured special needs trust may help protect eligibility while providing for supplemental needs, depending on the circumstances and applicable rules. Planning with an experienced attorney can help you evaluate the available options.
