Except in limited circumstances, children generally do not have a right to inherit anything (real property or personal property) from their parents. Laws do vary from state to state and in some states, for example, the head of a household may be prohibited from leaving the family homestead to anyone other than a surviving spouse or minor child if such person is alive.

And most states have laws that protect children (and sometimes grandchildren) against accidental inheritance in certain limited circumstances. These laws usually apply when a child is born after a parent’s will is executed, and because the will leaves property to the child’s siblings, it appears that the parent did not intend to disinherit the new child. In this circumstance the child who was not mentioned in the will may be eligible to inherit a portion of the estate like the child’s siblings. Such an omitted child is also known as a pretermitted child or a pretermitted heir.

In states with pretermitted child laws, the laws are usually located in the state’s statutes—often in the estates code or probate code.

In Wyoming, as in many states, children do not have an automatic right to inherit from their parents. The distribution of an estate is primarily determined by the deceased's will or, if there is no will, by state intestacy laws. However, Wyoming does have provisions to protect certain children who may have been unintentionally omitted from a will. Under Wyoming Statutes Title 2 - Wills, Estates and Fiduciary Relationships, a child born or adopted after the execution of a will, who is not provided for in any settlement and who is not mentioned in the will, may still be entitled to a share of the estate. This share is typically the portion they would have received if the decedent had died intestate. These provisions are designed to ensure that children who may have been inadvertently left out of a will, known as pretermitted children, are not completely disinherited. It's important to note that these protections may not apply if it can be shown that the omission was intentional or if the child was provided for outside of the will.
