Can Your Grandkids Sue You for Skipping Them in the Will?

Estate planning can be emotional, especially when decisions leave family members out. Many grandparents wonder: if I don’t leave anything to my grandchildren, can they sue me? The answer depends on state law, family circumstances, and how your will is written. While most states allow adults to freely decide who inherits, certain rules create exceptions. Here’s what you need to know if you plan to skip your grandkids in your estate plan.

1. Grandchildren Usually Have No Automatic Inheritance Rights

In most states, grandchildren aren’t considered “heirs” unless their parent (your child) has already passed away. If your child is alive, the grandkids usually have no legal standing to demand inheritance. That means leaving them out of your will is generally enforceable. Courts typically respect your right to distribute assets as you choose.

2. They May Sue Under “Pretermitted Heir” Laws

Some states have laws protecting heirs unintentionally left out of a will. These “pretermitted heir” rules often apply to children—but not always to grandchildren. If a grandchild claims you forgot or mistakenly excluded them, they may try to sue under this statute. Success usually depends on proving your omission wasn’t intentional. A clearly written will can prevent this type of challenge.

3. Challenges for Undue Influence or Capacity

Even if you leave grandchildren out intentionally, they could sue by questioning the validity of your will. Common claims include that you lacked mental capacity when signing or were pressured by someone else. According to the American Bar Association, these are among the most frequent challenges in probate court. While winning isn’t easy, it can delay the process and drain estate resources.

4. State Laws Can Provide Different Outcomes

Inheritance rules vary widely from state to state. For example, Louisiana follows community property law with forced heirship rules that may entitle certain descendants—including grandchildren in some cases—to part of the estate. Other states offer no such protections. Knowing your state’s approach is essential to avoiding surprises.

5. Stepchildren and Adopted Grandchildren May Complicate Things

If your grandchildren are adopted, they generally have the same rights as biological grandchildren. Step-grandchildren, however, usually have no rights unless you explicitly include them. These differences can create conflicts in blended families. Clear estate planning language avoids confusion and potential lawsuits.

6. Trusts Can Offer More Protection Against Challenges

Leaving assets through a living trust rather than a will can make it harder for skipped grandchildren to contest your decisions. Trusts generally avoid probate, which is where most inheritance disputes arise. They also allow you to spell out your intentions more specifically. Estate attorneys often recommend trusts for people worried about family lawsuits.

7. Communication Helps Prevent Lawsuits

Surprises are one of the top reasons family members go to court after a loved one dies. If you know you’re excluding grandchildren, discussing your decision ahead of time may reduce conflict. Some people also include a “no contest” clause in their will, which penalizes heirs who unsuccessfully challenge it. Transparency often prevents legal drama later.

Skipping Grandkids Requires Careful Planning

In most cases, grandchildren can’t force their way into your will if you’ve intentionally left them out. But depending on state law and family circumstances, they may still try to sue—especially if they suspect a mistake or undue influence. The safest strategy is to work with an estate attorney and make your wishes explicit. That way, your legacy goes exactly where you want it.
