Legal Question in Wills and Trusts in California

I do not see the connection between how the two documents resulted in her being able to steal any money. If the attorney acted below the standards of other attorneys then he is liable for malpractice if those actions resulted in an economic loss to his clients. If the attorney intentionally acted to assist someone to steal money then he is liable for a tort action and also contract breach and probably also a criminal charge, but would not be covered by his malpractice insurance as it was an intentional action and not mere negligence.

You have to show a connection between what he did and the stealing of the money. Whether or not there is a minor heir would have nothing to do with whether a bond would be required except if there was a minor heir without a guardian to give approval to the waiving of the bond. You need to tell us more facts for any one of us to decide if there is a basis to sue the lawyer.
