This is a question that cannot be answered without reference to the specific facts. Your own attorney is in the best position to advise you regarding the effect of any court orders.
A probate court has jurisdiction to determine all issues which are raised by the petition. It is also presumed that a court acts within its jurisdiction when it makes an order.
A written "follow-up" order is not always required particularly if the party is present in court when the order is made -- the minute order would suffice in most cases. Still, the party who brought the petition or who sought the order would probably submit a written order for the court to sign to be served on all parties entitled to notice.
I am licensed in California only and my answers on Avvo assume California law. Answers provided by me are for general information only. They are not legal advice. Answers must not be relied upon. Legal advice must be based on the interplay between specific exact facts and the law. This forum does not allow for the discussion of that interplay. My answer to any specific question would likely be different if that interplay were explored during an attorney-client relationship. I provide legal advice during the course of an attorney-client relationship only. The exchange of information through this forum does not establish such a relationship. That relationship is established only by personal and direct consultation with me followed by the execution of a written attorney-client agreement signed by each of us. The communications on this website are not privileged or confidential and I assume no duty to anyone by my participation on Avvo or because I have answered or commented on a question. All legal proceedings involve deadlines and time limiting statutes. So that legal rights are not lost for failure to timely take appropriate action and because I do not provide legal advice in answer to any question, if you are an interested party you should promptly and personally consult with an attorney for legal advice.
