Can I write my own will, power of attorney, have it notorized and would it be considered legal?

Yes, as long as the last will and testament and power of attorney are properly witnessed and notorized, they will be valid. Whether they accomplish what you want is another matter. An estate planning attorney might be something you consider to give you advice. Good luck to you. NOTE: This answer is made available by the lawyer for educational purposes only.
