Can I sue the Executor of the Estate for negligence, damages, and fraudulent charges to the Estate and the account of the Estate?

Question Details: My mother died almost three years ago, and both of my siblings passed on the Executive of the Estate position so my Grand Mother took over. It took her two years to file to be the Executor, another six months to hire a lawyer (who was not a probate lawyer, and she has recently taken funds out of the account to repair the property but the repairs have not been made. She has also sold all of the items at the estate through a "cash only" yard sale. The house has still not been listed. Can I sue for negligence and damages, and do you think I can win??
