As a layman with no legal experience whatsoever, I acted as executor and recently concluded probate... from another state entirely, without ever having set foot in California! All of the court-related matters were handled through the mail/fax thanks to the indispensable guidance of this book. Even if you're not acting as executor (or can't decide if you should), any party to probate should consider this book a "must-have". It is written for an executor but there is so much information on the 'mysterious' court procedures, anyone involved in a CA probate would be well-served by purchasing this book if for nothing other than to know "what is probate?" and "what is going on?"
As executor, it's easy enough to find the forms on California court sites, and some (sites) have sketchy details to assist in filling them out (the court probate examiner informed me the most common cause of delays in an individual probate case is due to improperly filled out forms). But even this relatively simple step requires you have an understanding of how the civil court system works; something I am fairly certain too few people have (myself included). Not only does this book familiarize you with the court system and its procedures (a rewarding learning experience in its own right), as well as gameplan the (typical) entire probate process but shows in explicit detail how to fill out every line of every form you'll most likely need.
None of this is to say probate is easy - I have not found mine to be and the estate was relatively simple. DIY probate is a lot of (detail/organizational) work. But I believe a large amount of the work involved for the first-time DIYer is due to unfamiliarity with the law, court procedures and its paperwork. Reading the book gave me the confidence that even so, I could do it myself and consult with an attorney on occasion rather than just washing my hands of it (and a pile of cash) by turning probate over to an attorney at the outset.
I was fortunate in that my probate case was relatively straightforward to be handled as it was. But even if it weren't, you MUST arm yourself with information of this nature if you're considering hiring an attorney. Get that information in one topical, detailed and pleasant-reading book.
Thanks so much Julia!
