In the US, most states have programs that assign volunteer advocates to children and youth in the foster care system (CASA and GAL are the acronyms). Anyone with a clean record w/r/t kids can do the training. It’s the weirdest band-aid on a broken system but until we fix the system, it’s also essential work that helps keep kids from falling through some terrible gaps.
I’ve been doing it since 2018 and I can attest that there is a huge need for advocates, especially for people who are anti-racist and committed to protecting LGBTQ kids, and to maintaining kinship bonds whenever it’s possible to do safely.
Technically you’re a voice for the kid in court but most of my work has been fixer shit: Calling every practice in a metro area until I can find someone to do a procedure, catching missed documents, making a nuisance of myself when the system drops a ball.
