In California, it is possible to complete the probate process without an attorney, but it can be challenging and time-consuming, especially if the estate is complex or if there are disputes among the beneficiaries.

One of the main benefits of hiring an attorney for probate is that the attorney can guide you through the process and help ensure that you are following all legal requirements and deadlines. An attorney can also provide assistance with tasks such as preparing and filing Court documents, communicating with beneficiaries, and managing the assets of the estate.

If you choose to proceed without an attorney, you need to be prepared to do a significant amount of work on your own. You will need to file all necessary Court documents, communicate with beneficiaries, and manage the assets of the estate. 

While it is possible to handle a probate without an attorney, you should seek the guidance of an experienced probate attorney to ensure that the process goes smoothly and that your rights and interests are protected.
