Typically, an unsupervised estate can be opened without a hearing, however, there are circumstances that may cause a court to have a hearing. Maybe the most common reason is if an interested party has an objection.
Please let me know if you would like to discuss in more detail.
As you can see from the other answers, a court will generally only hold a hearing if there is a dispute.
I am licensed to practice law in Michigan and Virginia and regularly handle cases of this sort. You should not rely on this answer. You should consult a lawyer so you can tell the lawyer the entire situation and get legal advice that is precisely tailored to your case.
I agree with my colleagues. I would simply add that an unsupervised informal proceeding can be converted to a formal or supervised proceeding, at any time, at the discretion of the court, upon request of the parties.
