What Is a Pretermitted Heir and How Does It Affect My Will?

A single missing name in your will can unravel your entire estate plan. Pretermitted heir laws exist to protect forgotten children, and they could override your final wishes if you are not careful.

A pretermitted heir is a child or descendant who is left out of a will, either by accident or because they were born after the will was written. Courts treat this omission as potentially unintentional, and most states have laws that step in to grant that heir a share of the estate regardless of what the will says.

These laws were designed to protect children from being accidentally disinherited. However, they can create serious legal complications for families and estates when a will is not carefully drafted. Understanding how pretermitted heir laws work is essential for anyone writing or updating a will. Here are five important things every testator needs to know.

1. Understanding the Legal Definition of a Pretermitted Heir

The term pretermitted comes from a Latin legal concept meaning passed over or omitted. A pretermitted heir is typically a child who does not appear in a testator's will, either because the will was written before the child was born or because the omission was a simple oversight. Courts in most states presume the omission was accidental unless the will clearly proves otherwise. The law then steps in to award that child a share of the estate equal to what they would have received if no will had existed at all.

2. Which States Have Pretermitted Heir Laws?

Nearly every U.S. state has some version of a pretermitted heir statute, though the specific rules vary widely. Some states protect only children born after the will was signed. Others protect any child not mentioned at all, regardless of when they were born. A few states also extend these protections to omitted spouses. Understanding your state's specific rules matters enormously when drafting a will. Common categories of pretermitted heir protection include:

• After-born children: Children born or adopted after the will was signed receive a statutory share of the estate.
• Omitted children: Any child not named or addressed in the will may be entitled to an intestate share.
• Omitted spouses: Some states protect a spouse who was married after the will was executed.
• Grandchildren: Certain states extend protection to grandchildren if their parent has already died.

3. Intentional vs. Accidental Omission: Why the Difference Matters

The law distinguishes between a child who was deliberately disinherited and one who was simply forgotten. An intentional disinheritance is legally valid in most states, but it must be clearly expressed in the will itself. A testator who wants to leave nothing to a specific child should name that child in the will and state the intention plainly. Without this language, a court may assume the omission was accidental and award that child an intestate share, effectively rewriting a portion of the estate plan against the testator's true wishes.

4. How a Pretermitted Heir Claim Can Disrupt Your Estate

A pretermitted heir claim can delay the probate process, trigger costly litigation, and reduce the inheritance received by other named beneficiaries. Courts treat these claims seriously, and the process of resolving them can take months or even years. Assets that were carefully assigned to specific people may be redirected to fund the pretermitted heir's statutory share. The emotional toll on families during this process is often significant, making prevention far more valuable than correction after the fact.

5. How to Protect Your Will From Pretermitted Heir Challenges

The most effective protection is a clearly drafted will that addresses every child by name. Even if you choose to leave a child nothing, naming them and acknowledging the decision removes any ambiguity a court might exploit. Updating your will after major life events, such as the birth of a new child, a remarriage, or the death of a beneficiary, is equally important. A well-written will should also include a clause confirming that any omissions are intentional rather than accidental. This single step can prevent years of painful and expensive legal disputes.

The Big Question: Should You Update Your Will to Address Pretermitted Heirs?
