California Probate Form DE-161 Inventory and Appraisal Attachment is a necessary part of any full probate. It is used to list all assets that will be appraised in the probate. Attachment 1 is used to list assets the administrator and the attorney can easily appraise (basically cash assets like bank accounts) and attachment 2 is used for everything that the probate referee is needed for (real estate, stocks, bonds, businesses, etc…). In some cases you would only use one attachment (either 1 or 2) and in some cases you use both. The only time you would not use this form is if you were filing a final inventory showing zero assets but this is rarely done.
