The Salvation Army hasn't recognized that the parents are addicts?

Anyway - you are not "entitled" to custody of the child. Ask the parents to sign guardianship over to you.

If the child is in danger or abused you need to file a Police Report.

IF the child is placed in foster care you can apply to be her guardian.
