Legal Question in Wills and Trusts in California

Without knowing the procedural status of the probate case, there is no way to answer the question. Has a probate been opened? Is there an administrator appointed yet? If so, who, and what has the administrator done and/or filed so far? What, if anything, is currently pending before the court for any determinations? Etc., etc., etc. You don't just start a probate case by filing an objection to something, and you don't file an objection unless something is pending. If she has already been appointed administrator, you may have lost your chance to object to that, but you may still have opportunities to object to her receiving assets. There are just too many "ifs" to deal with what you can or should do via an internet Q&A.
