My question involves guardianship in the State of: Delaware

I had legal guardianship of my 22yo son, both person and property. He was residing in a facility that did not want him there but I would not agree with discharge. My legal rights to medical decisions on his behalf were not honored, there was no care plan set up that I was included in. He died and of course guardianship was terminated. Is there anything I can do about them not following the law while he was alive? I am now administrator of his estate.
