Is a child born out of wedlock entitle to any of his father's estate?

Yes, a child born out of wedlock can be entitled to their father's estate, depending on the laws of the jurisdiction and whether paternity has been established. In many places, if the father acknowledges the child or if paternity is legally recognized, the child may have the same inheritance rights as a legitimate child. However, this can vary significantly based on local laws and the father's estate planning choices, such as wills or trusts. It's advisable to consult legal experts for specific situations.
