Given I haven't had the opportunity to speak or attend court, can I at least write the judge?

I and my partner of 13 yrs has raised our grandson for 4 yrs. The child is 4 yrs. of age, we never sought legal custody. I pay all bills, entertainment and invested interest in regards of the child needs been met. he child got out of the house while I was at work. The state saw fit to remove the child from the home until my partner complete their demands. PA has something call loco parentis. I don't have extra money to be able to retain a attorney.
