8 Common Mistakes People Make When Creating a Will and How to Avoid Them

Mar 2, 2026 | Video Transcripts

Creating a will is one of the most significant steps you can take to ensure your loved ones are protected after you pass away. A properly drafted will gives you control over how your assets are distributed, who will care for your minor children, and how your final wishes are carried out. Unfortunately, many people make avoidable mistakes during the will creation process that can lead to family disputes, costly litigation, and outcomes that don’t reflect what they truly wanted.

Understanding these common errors is the first step toward making sure your estate plan holds up when it matters most. Below, we walk through some of the most frequent issues that arise with wills and offer guidance on how to avoid them.

Failing to Sign or Properly Execute the Will

It may sound surprising, but one of the most common mistakes people make is failing to sign their own will. A document can be notarized and appear official, but if the person who created it never actually signed it, it may not be legally valid. This simple oversight can throw an entire estate plan into question and leave your family scrambling during an already difficult time.

Proper execution of a will involves more than just putting pen to paper. Depending on where you live, there are specific requirements for how a will must be signed, witnessed, and sometimes notarized. Skipping any of these steps could render the document unenforceable. Working with a knowledgeable attorney ensures that every procedural requirement is met so your will stands up in court.

Including Incorrect Personal Information

Another surprisingly common issue is the inclusion of incorrect personal details within a will. Misspelled names, wrong birth dates, or inaccurate descriptions of assets can all create confusion and open the door to legal challenges. If a beneficiary’s name is misspelled, for example, it could create ambiguity about who was intended to receive a particular asset.

Taking the time to carefully review every detail in your will before it is finalized can prevent these types of problems. An estate planning attorney will verify names, dates, and asset descriptions to make sure everything is accurate and clearly stated.

Failing to Comply with State Laws

Every state has its own laws governing how a will must be created, signed, and witnessed. A will that is perfectly valid in one state may not meet the legal requirements in another. If you have relocated or own property in multiple states, this becomes an especially important consideration.

Working with an attorney who understands the specific requirements of the state where you reside is essential. ProvenLaw practices in multiple states and is well-versed in the procedural differences that can make or break a will’s validity. Ensuring compliance with your state’s laws from the start can save your family from heartache and legal battles down the road.

Using Vague or Ambiguous Language

Ambiguity is one of the most dangerous issues that can appear in a will. When the language in your will is open to interpretation, it invites disagreement among your beneficiaries. A parent might tell one child something verbally but write something slightly different in their will, creating confusion and hurt feelings that can escalate into full-blown legal disputes.

Clear, precise language is critical in estate planning documents. Every provision should leave no room for misunderstanding about your intentions. An attorney can help you articulate your wishes in a way that is legally sound and easy for everyone to understand, reducing the likelihood of conflict among your loved ones.

Not Updating Your Will Regularly

Life changes constantly, and your will should reflect those changes. If you don’t update your will regularly, you may find that it names a beneficiary you no longer wish to include or an executor who has passed away or is no longer someone you trust. Outdated wills can create significant gaps that complicate the probate process and lead to unintended consequences.

Major life events such as marriages, divorces, births, deaths, and significant changes in your financial situation should all prompt a review of your will. Even without a major event, it is a good practice to review your estate plan every few years to make sure it still reflects your current wishes and circumstances.

Relying on Online or Homemade Will Kits

The availability of online and do-it-yourself will kits has made it tempting for people to try to handle their estate planning on their own. While these tools can sometimes produce a basic document, they often miss key provisions that are essential for a comprehensive estate plan. One common issue is a will that assigns specific assets to specific people but fails to address what happens to everything else.

Without a residuary clause or other catch-all provision, assets that are not specifically mentioned in the will may be distributed according to state intestacy laws rather than your wishes. This can lead to expensive and emotionally draining legal proceedings. The money saved by using a DIY kit can quickly be dwarfed by the legal costs your family faces when the will falls short.

Improperly Witnessed Documents

Witness requirements for wills vary from state to state. Some states require two witnesses, while others may have additional requirements about who can serve as a witness. Failing to meet these requirements can invalidate your will entirely, even if every other aspect of the document is perfect.

Because these rules differ depending on where you live, it is crucial to work with an attorney who knows exactly what your state requires. ProvenLaw practices in multiple states and ensures that every will is properly witnessed in accordance with the applicable laws, giving you confidence that your document will hold up when it is needed.

Assigning Specific Assets to Specific People

While it might seem straightforward to leave a particular bank account or piece of property to a particular person, this approach can create unexpected problems. If you become incapacitated and someone is managing your finances on your behalf, they may spend from certain accounts to cover your care, leaving some beneficiaries with significantly less than you intended.

This type of situation can breed resentment and lead to litigation among family members. A more thoughtful approach to asset distribution, such as using percentages rather than specific accounts, can help ensure that everyone is treated fairly regardless of what happens during your lifetime.

Protecting What Matters Most

At the end of the day, the purpose of a will is not just about distributing property. It is about protecting the people you love and preserving the relationships that matter most. A well-drafted will can minimize the chances of family conflict and give your loved ones peace of mind during a difficult time.
