Legal Question in Wills and Trusts in Arizona

The cemetary plot is real estate and to receive title or convey title, a deed must be made and recorded. You have to go back to the probate of your grandmother's will to see if the plot was deeded to you as a distribution of that estate, and recorded so that title was in your name. Then, see if the woman made a deed to the current owner of record. Once you have tracked down what happened, then you could bring a "quiet title" action to regain ownership of the plot or the damages. If the buyer bought in good faith, you may not be able to recover the plot. I don't know how long it has been since all of this happened, but you must take action immediately to learn what your rights are and what action you should take.
