Q: This is for my dad. He wants to make sure that everything is in place because he knows I will be killing him soon.
A: You both will need a lawyer. Him for estate planning documents and you for homicide charges. Some people try to pull estate planning documents from the internet and do it themselves, but this is not advised. The documents from the internet are sometimes not specifically compliant with the laws of the state in which you live, nor address the specific needs of your situation. Call several lawyers to determine who is in your price range and who you are comfortable with. The attorney can also refer you to a good criminal defense attorney. Perhaps an insanity defense will be appropriate.
