Petitioning the Court to Unseal Your Records

Hello I know this post is really old and I’m not sure if I will get a response but I’m kind of going through the same thing and this is my situation I am 25 and had a closed adopted as a baby In French camp ,California(San Joaquin County). I am trying to find my biological parents I know the hospital I was born but on my birth certificate it shows my adoptive parents on the certificate. My adopted parents passed away and none of my adoptive family knows anything. I recently sent a letter requesting my non identifying information and called them and they said they received it and it could take up to the most 3 months to get that information back but usually doesn't take that long. l also just ordered 23Me kit and Ancestry kit to see if I match with any relatives. And last thing I did was called the courthouse and they told me forms I can print out to petition the court to unseal my birth certificate and I filled out all that paperwork and going to mail it off tommorow and I'm the petition I stated I wanted it for medical reasons and I also include a form from my doctor that I will be mailing along with it so l'm not sure how that will go. And once I get my 23nme and ancestry result I will be signup for a free search angel and will be signing up for adoption registry. Is there any other advice or steps I should take ? Or is this a good start. Thank you all for the advice.
