What is the inheritance situation for nonmarital children from their father?

In the context of inheritance rights for nonmarital children, they typically have the ability to inherit from their mothers automatically, as a maternal connection is established at birth irrespective of marital status. This means that nonmarital children are considered legal heirs of their mothers and are entitled to inherit everything that their mothers have to pass on.

Regarding inheritance from their fathers, different jurisdictions may have specific laws that determine how nonmarital children can inherit. Many statutes require that for a nonmarital child to inherit from a father, there needs to be a formal acknowledgment of paternity or a legal action to establish paternity. Consequently, this often results in nonmarital children not inheriting from their biological fathers unless specific legal steps are taken, such as the father recognizing their status after the child's birth or through a paternity claim.

This complexity leads to the correct understanding of the inheritance rights of nonmarital children. Since they inherit from their mothers without any additional legal proceedings, the answer that states they only inherit from the mother accurately captures this standard legal principle, while also indicating that their ability to inherit from their fathers is generally contingent upon additional legal recognition which is not guaranteed.
