When it comes to wills, one size does not fit all. Each state has its own legal requirements—and failing to follow them can result in your will being partially or completely invalid. In this post, we explain how state laws differ, and why ignoring them in a DIY will can derail your entire estate plan.
It’s easy to assume that a will is just a will—write it, sign it, and you’re good. But the reality is far more complex. In the United States, each state has its own legal requirements for what makes a will valid. These differences aren’t minor—they’re critical.
If your will doesn’t follow your state’s formal rules, it may be:
- Challenged in court,
- Deemed partially invalid, or
- Thrown out altogether—leaving your estate to be distributed under default intestacy laws, not your wishes.
This post explores why understanding and complying with state law is essential when drafting a will, especially if you’re using an online tool, a template, or attempting to write one yourself.
How State Laws Differ on Wills
State laws vary widely on issues such as:
1. Witness Requirements
Most states require:
- Two adult witnesses who are not beneficiaries,
- Witnesses to be present when you sign the will,
- Witnesses to sign in each other’s presence.
Some states allow notarization, others do not. And in certain states, the will may be invalid if your witness is also inheriting property.
2. Holographic (Handwritten) Wills
- Some states recognize handwritten wills if the material parts and signature are in your handwriting.
- Other states do not accept them at all, or only under narrow circumstances.
- Even where allowed, holographic wills are more easily challenged.
3. Self-Proving Affidavits
A self-proving affidavit is a notarized statement from your witnesses confirming the will’s validity.
- Some states require it for easier probate.
- Others make it optional but strongly recommended.
- In a few states, self-proving wills must follow strict formatting, or they won’t be accepted.
4. Community Property vs. Common Law States
- In community property states (like Texas), your spouse is entitled to half of what you acquired during the marriage.
- In common law states, property division is handled differently, often by title.
Failing to understand how your state handles marital or jointly owned property can cause accidental disinheritance or unfair distributions.
5. Revocation and Amendments
- Some states treat marking up or crossing out a will as a revocation.
- Others require formal revocation clauses or a properly executed codicil to make changes.
What might be seen as an update in one state could be seen as a full revocation in another.
Real-World Example
Jack wrote a will using an online template while living in Texas. He later moved to Florida and passed away a few years later. His will:
- Had only one witness (Texas requires two),
- Included handwritten notes added later (Texas doesn’t recognize post-signature edits),
- Failed to account for Texas’s unique rules on homestead property and spousal rights.
The court deemed parts of the will invalid, and his spouse ended up inheriting more than he had intended—causing conflict with his adult children and delay in probate.
Why DIY Wills Are Especially Vulnerable
Most online templates and DIY kits:
- Are written for generic use and not tailored to your state,
- Don’t update with changing local laws,
- May not address state-specific asset types, such as oil and gas royalties, community property, or separate vs. marital assets.
These gaps create opportunities for will contests, invalidation, and costly legal disputes.
What Else State Law Affects
Beyond will validity, your state also controls:
- Who can serve as executor or trustee (some states restrict out-of-state fiduciaries),
- Who must be notified in probate,
- Bond requirements for executors,
- Inheritance rights of spouses and minor children,
- Tax obligations on inheritances or estate size.
Even the format of the will (font size, margins, headings) is dictated by law in some jurisdictions.
How to Protect Your Will from State Law Pitfalls
- Work with an estate planning attorney in your state
They’ll ensure your will complies with current local law and court preferences. - Avoid generic templates
If you do use one, have it reviewed by a local attorney to make sure it meets your state’s legal requirements. - Update your plan when you move
If you relocate to a different state, especially with different probate rules, review and update your will accordingly. - Stay current with law changes
State laws evolve. Review your plan at least every 3–5 years or after any major legislative update.
Final Thoughts
Writing your own will without understanding your state’s legal requirements is like building a house without knowing the local building codes. It may look fine at first—but it could collapse under pressure.
State laws matter more than you think. They determine how your will is interpreted, enforced, or rejected entirely.
If your goal is to protect your family and ensure your wishes are honored, don’t leave it to chance. Make sure your estate plan is not just well-intentioned, but legally enforceable—exactly where you live.
