It's possible that you could have a claim against the attorney for legal malpractice, but it would depend upon all of the facts. If you consult further with an attorney (which I urge you to do), additional information will be helpful. What are the differences between the will she did not sign and the previous one? Do you have copies? What is the amount that will pass through your grandmother's estate? Who has direct knowledge of the facts? Feel free to contact me to discuss further (although our offices are in San Diego and Los Angeles, we do take cases in SLO County). Good luck.
