The individual owns their own house and lives in it, has a legal guardian but wants to create a will and not sure if they can go ahead independently or if the legal guardian must be present. The purpose of guardian was due to an aneurysm 4 yrs ago but since has come along ways and lives alone.
We have three different types or levels of general guardianship. Person,Estate,Summary Admin, Person and Estate.
So I would presume it would depend on exactly what type of guardianship has been assigned.
I would suggest you contact a certified elder care attorney for guidance. Our attorney also does wills and I am consulting him on preparing my own will to ensure continued care for my wife.
