The executor of the estate submits the will to probate court if it is necessary to do so. It is only necessary when there is a large estate, many heirs, outstanding debts, or a possibility if someone is going to contest the will. In a case where the will isn't going to be contested a lot of time and money can be saved by doing a "short probate" if available or not choosing to submit the will to probate court at all. You will still need to go to probate court. The process is faster though and you will be put on the uncontested docket.
