Creating an estate plan is a major accomplishment, but it is not a “set it and forget it” task. Laws change, life changes, and assets change. Any of those shifts can cause an outdated estate plan to stop working the way you intended.
For individuals and families in Missouri and Kansas, regularly reviewing and updating your estate plan is essential. A current plan helps make sure your wishes are followed, your loved ones are protected, and your documents continue to comply with applicable state law.
Whether you already have a will, trust, power of attorney, healthcare directive, or beneficiary designations in place, it is important to know when your plan should be reviewed. Working with an experienced attorney at Kelly Law Firm can help you keep your estate plan organized, effective, and aligned with your goals.
A Good Rule of Thumb: Review Your Estate Plan Every Three to Five Years

As a general guideline, most people should review their estate plan every three to five years, even if nothing major has happened.
This does not always mean rewriting your documents from scratch. In many cases, a review is simply a check-in to confirm that your beneficiaries, decision-makers, asset ownership, and instructions still make sense.
During this review, your attorney can also identify legal changes that may affect your plan. Estate planning laws, tax rules, probate procedures, and healthcare decision-making requirements can change over time. Even if your personal situation feels the same, the law may not be.
For Missouri and Kansas residents, a routine estate plan review can help answer important questions, such as:
- Are your named beneficiaries still correct?
- Are your personal representative, trustee, and agents still the right people?
- Do your assets match the structure of your plan?
- Are your powers of attorney and healthcare documents still up to date?
- Would your family avoid unnecessary probate delays?
- Does your plan still reflect your current wishes?
If it has been several years since you looked at your documents, it may be time to schedule a review with an attorney who handles estate planning services.
Life Events That Should Trigger an Immediate Estate Plan Review
Some life changes should prompt an immediate review of your estate plan, even if your documents were recently updated. These events can directly affect who inherits from you, who has authority to act on your behalf, and how your assets are handled.
Marriage, Divorce, or Remarriage

Marriage, divorce, or remarriage can significantly affect your estate plan. These changes may impact how property passes at death, who has decision-making authority, and whether your existing documents still reflect your intentions.
For example, an old will or trust may name a former spouse, leave out a new spouse, or fail to account for stepchildren. Beneficiary designations on retirement accounts, life insurance policies, and payable-on-death accounts may also need to be updated.
Relying on an outdated plan after a major relationship change can lead to unintended results. In some cases, it can also create conflict among family members.
Birth or Adoption of a Child

Welcoming a child into your family is one of the most important reasons to update your estate plan.
Parents should review guardianship provisions, inheritance instructions, and long-term planning for minor children. Without proper planning, a court may need to decide who raises your child or manages assets left for them.
An updated estate plan can help you name trusted guardians, create financial protections, and outline how assets should be used for your child’s care, education, and support.
Death or Incapacity of a Named Decision-Maker
Your estate plan likely names several important people, including a personal representative, trustee, guardian, healthcare agent, or financial power of attorney.
If one of those people passes away, becomes incapacitated, moves away, or is no longer a good fit, your documents should be updated promptly. A strong estate plan should include backup decision-makers, but those backups also need to be reviewed from time to time.
Significant Changes in Assets
Major financial changes can affect whether your estate plan still works as intended.
You should review your plan after:
- Buying or selling a home
- Starting, buying, or selling a business
- Receiving an inheritance
- Acquiring investment property
- Opening new financial accounts
- Experiencing a major increase or decrease in wealth
- Taking on significant debt
Asset ownership matters in estate planning. For example, a trust may not fully serve its purpose if important assets were never transferred into it. Likewise, beneficiary designations may override instructions in a will or trust if they are not coordinated properly.
Moving Between Missouri and Kansas
Because estate planning is governed by state law, moving across state lines is an especially important reason to review your documents.
For Kansas City-area residents, moves between Missouri and Kansas are common. While many estate planning documents may remain valid after a move, they may not be optimal under your new state’s laws.
A review can help ensure your documents align with local rules involving probate, powers of attorney, healthcare decision-making, and property ownership.
You can learn more about probate court processes through official state court resources, including the Missouri Courts and the Kansas Judicial Branch. These resources can be helpful, but they are not a substitute for personalized legal advice.
Changes in Goals or Family Dynamics

Not every estate plan update is triggered by a formal legal event. Sometimes, your goals simply change.
Beneficiaries may become financially independent. Relationships may shift. A family member may develop special financial or medical needs. Charitable giving goals may become more important. You may also decide that a person you once trusted is no longer the right choice to manage your affairs.
Estate planning is about intent. If your intentions change, your documents should change with them.
A well-maintained estate plan can help reduce confusion and make your wishes easier for your loved ones to follow.
Do Beneficiary Designations Need to Be Updated Too?
Yes. Beneficiary designations are a key part of your overall estate plan.
Accounts such as life insurance policies, retirement plans, annuities, and payable-on-death bank accounts often pass outside of a will. That means the beneficiary form on file with the financial institution may control who receives the asset.
This is why beneficiary designations should be reviewed along with your will, trust, and other estate planning documents.
For federal tax and retirement account information, the IRS estate and gift tax resource page may provide general background. However, because every situation is different, it is best to speak with an estate planning attorney before making major changes.
The Cost of Letting an Estate Plan Go Stale
Outdated estate plans are one of the most common sources of confusion and conflict during estate administration.
Old documents can create problems such as:
- Beneficiaries receiving assets you no longer intended them to receive
- Former spouses or outdated decision-makers remaining in control
- Missing backup agents or trustees
- Assets passing through probate unnecessarily
- Family disputes over unclear instructions
- Delays in administering the estate
- Increased legal costs for loved ones
In many cases, these problems can be avoided with a simple review and update.
Keeping your estate plan current is not just about legal documents. It is about giving your family clarity during a difficult time.
How an Estate Planning Attorney Can Help
An experienced estate planning attorney can review your current documents and help determine whether updates are needed.
This may include reviewing your:
- Will
- Revocable living trust
- Financial power of attorney
- Healthcare power of attorney
- Living will or advance healthcare directive
- Beneficiary designations
- Real estate ownership
- Business succession plans
- Guardianship nominations
- Probate avoidance strategies
For residents in Missouri and Kansas, local guidance matters. State laws can affect how documents are interpreted, how probate is handled, and how decision-making authority is recognized.
The team at Kelly Law Firm can help individuals and families review existing estate plans, update outdated documents, and create customized plans through their estate planning services.
