Step Parent Adoption

What is the name of your state? California

My ex has agreed to let my 13 year old be adopted by my husband. They have not had any contact in almost 1 1/2 years nor do either of them want contact with each other.

What is the correct paperwork to fill out and have my ex sign to agree to this adoption?
