The other requirement is that there has to be another adult ready to step into the terminated parent's shoes and assume the terminated parent's support obligation towards the child. Hope this helps. Elizabeth Powell
Step 1: Contact a qualified Washington family lawyer. There are some good ones on this web site.
Washington requires court review of termination of parental rights, both voluntary and involuntary. I believe there is also some mandatory counseling involved. The best interests of the child are always the primary concern. Choose a lawyer and start working on the process.
