And do not assume that if you are paying an estate attorney, rejection should never occur. Rejections can occur for many reasons. The forms filed may have been updated or laws or procedures changed since the blank forms were obtained. Courts do not have the resources to track down and notify anyone with a probate pending as to the changes. So the only way to find out is by filing a petition or other documents that are rejected.
Many rejections are for what appear to be minor technicalities.
You may assume that some minute technical correction is absurd, but clerks see thousands of probate matters each year. They may be sensitive to issues that you are unaware of. They may have learned of the importance of certain fine points from problems that have occurred in an unusual case or two. In many situations, the clerks are aware of how the judge who must issue an order wants the paperwork prepared. It is certainly preferable to have the clerk identify the problem so you can correct it before more time is spent having incorrect documents await the judge's rejection.
