Guardianship of the Estate of Minor (Fresno County, CA)

In 2001, I was injured on the job and received a large monetary settlement. At the time, I was married and my spouse and I had planned on purchasing some land to have a custom home built for our family. I found an acre of property and decided to purchase it. During the transaction I had my three children along with myself placed on the title deed as owners of the property. One of my children is a minor (Age 12).
Since then, my spouse and I have divorced, so now I want to sell the property (empty one acre lot) and purchase a single family residence closer to where I work.
However, I understand that I need to become Guardian of the Estate in order to sell the property on behalf of my child who is a minor. I am doing everything myself since I cannot afford an attorney. I have already filed a petition with the Fresno County Superior Court, but the Judge has decided to appoint a public guardian of the estate for my child. I completely understand that my son's portion of the estate shall remain in a blocked account which can only be accessed with the court's approval. The Judge recommended that I come up with a valid reason to sell the property. I don't know what step is next and I am running out of time.

Anyone with information regarding my situation, please feel free to reply.
Your help is greatly appreciated.

Sounds like poster PaleRider44 is in a similar situation. Please read his post in the same Wills, Trusts and Estates titled: "How can my 13 year old son access a bank account his deceased grandma left him?"
