Legal Question in Wills and Trusts in California

Re: Legality of will and time frame

I'll actually answer your question. Your grandmother's will

must be a holographic will if she is the only one who signed it.

A holographic will is one that is entirely in your grandmother's

own handwriting. If she just signed a written will or filled out

the blanks in a preprinted will, she must sign the will in front of

2 witnesses and it must be notarized. This is called a self-proved

will because it is signed in front of 2 witnesses and notarized. It is

automatically valid.

From your question I couldn't tell if the will was totally in your

grandmother's handwriting. If it isn't, it isn't valid under Idaho law.
