Estate Planning Attorney
Do you mean that the Probate judge dismissed your Petition without prejudice? If so, you would likely be able to refile the Petition, so long as the defects contained in your first Petition have been corrected. Probate Petitions, even where there are applicable judicial counsel forms, can be complicated. I would recommend that you have a Probate attorney review your documents so that you can avoid any further problems with your Petition.
In order to respond fully to your question, more information is needed.The answer here could depend on the basis for your Probate Petition, the actual court ruling, and the applicable statute of limitations. I would recommend that you re-post with additional information.
