The Dangers of DIY Wills: Don’t Risk Your Family’s Future

October 13, 2026

Creating a will is one of those tasks many people know they should handle but put off for far too long. When people finally do decide to take that first step, it’s becoming increasingly common for them to be tempted by a simple online template or an AI-generated will service. 

They often will advertise themselves as being convenient, dirt cheap, and delivering you a finished estate plan in just a few minutes. However, we’ve seen a wide majority of them leave out critical components that may not become apparent until it is too late to correct it. An unclear provision, an overlooked beneficiary, or a failure to follow New York’s legal requirements could leave your loved ones facing confusion, delays, unexpected expenses, or even a distribution of your assets that you never intended.

DIY wills are not automatically invalid, but there is danger in assuming that a document is legally effective and complete simply because it looks official. Estate planning is about more than filling out a form – it is about making sure your specific wishes can actually be carried out when your family needs them most.

With that being said, here are 6 ways a well-intended DIY Estate Plan could be fraught with legal pitfalls. 

1. A Simple Signing Mistake Could Jeopardize Your Will

One of the most common misconceptions about DIY wills is that completing and signing the document is all that is required.

In New York, a conventional will generally must be in writing, signed at the end by the person making it, and executed with specific witnessing formalities. The person must acknowledge the signature to the witnesses and declare that the document is their will. At least two witnesses must attest to the signature at the testator’s request within the required period. There are limited statutory exceptions, but simply typing your wishes, signing a document electronically, or having someone notarize a form does not necessarily create a valid will.

A template may provide instructions, but it cannot ensure that those instructions are followed correctly. That opens the door for the execution of the will to be challenged after death, leaving the people left behind to deal with the serious consequences. In some cases, an invalid will could mean that an earlier valid will controls or that New York’s intestacy laws determine who receives your property.

2. Generic Templates May Overlook the People You Want to Protect

Estate planning is rarely as simple as dividing everything equally among a few people. A generic form may not ask the right questions about your circumstances or explain the consequences of your answers.

For example, what happens if one of your beneficiaries dies before you? What if you have children from a previous relationship, want to leave different amounts to different beneficiaries, or own a business with other partners? What if a loved one has a disability, receives means-tested benefits, or may need help managing an inheritance?

These situations require careful & professional planning. A provision that seems fair or straightforward today may create an entirely different result after a death, remarriage, or change in family circumstances. New York law also provides certain rights to surviving spouses that may affect how an estate can be distributed, regardless of what a will says.

The risk is not always that your will says something incorrectly, sometimes, it can be something the will fails to address at all. 

3. Planning for Children Requires More Than Naming a Beneficiary

For parents, a will is an especially important document. It should address who you would want to care for your children and how assets left to them should be managed, and for how long.

However, naming someone as a guardian in a will does not automatically give that person legal guardianship. In New York, the Surrogate’s Court must approve the appointment. Parents should also consider who would manage a child’s inheritance, whether a trust is appropriate, and what should happen if the person they selected cannot serve.

A DIY document that simply leaves everything to a minor child does not provide the structure or flexibility a parent truly wants for their child. Without appropriate planning, the management and eventual distribution of that inheritance may be governed by legal procedures in New York State rather than the personalized arrangements the parent would have preferred.

4. Your Will May Not Control Everything You Own

Another common mistake is assuming that a will determines who receives every asset.

Many assets can pass outside of probate through beneficiary designations, joint ownership, trusts, or other arrangements. Life insurance policies, retirement accounts, and certain financial accounts may have their own instructions governing who receives them. As a result, the beneficiary listed on an account may receive the asset even when the will expresses a different intention, subject to applicable law.

Imagine updating your will after a divorce but forgetting to review an old beneficiary designation. Or creating a trust but never taking the necessary steps to transfer appropriate assets into it. The paperwork may appear complete, while the overall plan remains inconsistent.

A will that does not account for the rest of your financial life creates a false sense of security.

5. A Will Does Not Protect You During Every Stage of Life

Estate planning is not only about what happens after your death. An effective estate plan should also address what happens if you become seriously ill or are temporarily or permanently unable to make decisions for yourself.

A will does not, by itself, appoint someone to manage your finances or make medical decisions while you are alive. Depending on your circumstances, other documents may be appropriate; such as a power of attorney, health care proxy, living will, or trust.

Without proper planning, loved ones may face uncertainty about who has authority to act and what your wishes would have been. In some situations, court involvement may be necessary to establish legal authority

6. Saving Money Today Could Create Greater Costs Later

It is understandable to want to save money, especially when estate planning can feel like something you will not need for many years. But the true cost of a will is not always the price paid to create it.

If a document is unclear, improperly executed, or inconsistent with other parts of an estate plan, resolving those issues after death can require additional legal work. In some cases, disagreements may lead to contested probate proceedings or litigation.

These problems can also take an emotional toll. Family members may be left trying to interpret unclear instructions, resolve disagreements, or make difficult decisions without knowing what their loved one truly intended.

The goal is not to create the most complicated estate plan possible. It is to create one that is appropriate for your circumstances, legally effective, and understandable to the people who will eventually rely on it.

What If You Already Have a DIY Will?

If you have already created a will using an online service, a template, or an AI tool, that does not necessarily mean you need to start over. It does mean that having the document reviewed may be worthwhile.

An estate planning attorney can evaluate whether the will was properly executed, whether its provisions reflect your intentions, and whether it works with your other assets and planning documents. A review may also identify issues involving beneficiaries, executors, guardians, trusts, or changes in your family that should be addressed.

The same is true of an older attorney-drafted will. Marriage, divorce, the birth of a child, the purchase of a home, the death of a beneficiary, or a significant change in finances can all be reasons to revisit your plan.

Don’t Leave Your Family’s Future to a Template

A will is one of the few documents that may have its greatest impact when you are no longer here to clarify what you meant. Unfortunately, that is also when mistakes can become the most difficult – and sometimes impossible – to correct.

Taking the time to prepare your estate plan properly can help reduce uncertainty, prevent avoidable complications, and give your loved ones clearer guidance during an already difficult time.

Frequently Asked Questions

Is an online will legal in New York?

An online service legally can be used to prepare a will, but the document must still satisfy all of the applicable New York legal requirements. Completing a questionnaire or downloading a form does not, by itself, make the will valid. The document’s contents and execution must be evaluated under the law.

Can I write my own will without an attorney?

Yes, a person can prepare their own will. However, New York has specific requirements for valid wills and handwritten, or unwitnessed wills are generally recognized only in limited circumstances. The more complicated your family or financial situation, the greater the risk that a self-prepared document may not address everything you intend.

Can I use ChatGPT or another AI tool to create my will?

AI may be useful for learning about estate-planning terminology or helping you organize questions, but it should not be relied upon to determine whether a legal document is appropriate for your circumstances. AI-generated language can be incomplete, inaccurate, or unsuitable for New York law, and the tool cannot independently verify that your will has been properly executed.

Does having a will mean my family can avoid probate?

Not necessarily. A will generally must be admitted to probate before it can be used to administer probate assets. Certain assets may pass outside probate through other arrangements, and trusts may be useful in some circumstances, but avoiding probate requires more than simply having a will.
