After my second request for a copy of Mocienne Elizabeth Petit Jackson's claim was rejected by RTL Boulevard this morning and their refusal to tell me who their source is I decided to make another screenshot of that claim and take a second look at it.
By comparing this screenshot to previous released court documents I was able to determine which form MPJ filed:


The form used is DE-111, which can be found here: http://www.courtinfo.ca.gov/forms/documents/de111.pdf
Now look at the marked checkbox:
"Authorization to Administer Under the Independent Administration of Estates Act" is marked.
Going back to the website of the LA Superiour Court at
https://www.lasuperiorcourt.org/civilCa ... Type=Civil, Case number BP117321:


So...MPJ's claim is filed, and listed on the website of the LA Superior Court.
Am I correct when I say that "Party whitout attony" indicates that she filed the claim herself on July 23 2010 in Los Angeles?
