Forced heirship is a concept that provides that all of your children have a right to a portion of your estate upon your death. In other words, each of your children must get part of your estate. There are limited circumstances under which a child can be disinherited. Absent one of these circumstances, if you do not provide a child with his or her forced portion, he or she can sue to claim it. The idea comes from Roman and French Civil Law but is not part of the common law of England. All states follow the Common Law of England rather than the Civil Law of Europe except for Louisiana. Louisiana has forced heirship, the other states generally do not have it.
No Texas Forced Heirship.
Texas was part of Mexico before its independence. Mexico’s law is based on the Civil Law of Europe. Because Mexico had forced heirship, it was part of Texas law at the time of Texas’ independence. It remained part of Texas law for only a short time. Texas repealed forced heirship in 1856. As a result, a Texas will can leave property to a child or not leave property to a child. There is no law that requires a person in Texas to leave property to a child, a spouse or anyone else. There is complete freedom to leave property to anyone regardless of their relationship to the maker of a will.

Pretermitted Children and Spouses.
Note that forced heirship is different from the concept of pretermitted children and spouses. Pretermitted children are those children born after a will is executed and not otherwise provided for by the decedent. The law treats these children as forgotten children and they inherit as if there was no will. Texas doesn’t recognize pretermitted spouses but some states do. The same principles apply as apply to pretermitted children. I have written about pretermitted children here and here. I have written about pretermitted spouses here and here.
