Probate is a process. If you were appointed administrator you needed to submit an order to the court and have Letters issued. Until Letters are issued, the 4 month creditors claim period doesn't begin to run. Until then, the estate must stay open. If it has been a year and Letters have not been issued, I strongly suggest you hire an attorney, otherwise another year might go by without the estate being closed because the proper procedures are not being followed.
You should receive an order for probate, and Letters of Special Administration. In most jurisdictions, you have to submit these to the court, prior to the hearing, and have the probate examiner review it, before they are issued by the court.

Your question is not clear because in Probate, a "temporary" position is really a special administrator. When some dies you can file for formal probate or if something needs to be dealt with immediately, you can apply for letters of special administration at the time of filing for probate. If the court approved you as a Special Administrator, your powers will be specified in the order. You need to complete the judicial council form and submit it to the court. In addition, you will need to submit Letter of Special Administration, also a judicial council form for issuance by the court.
