challenge adoption

What is the name of your state? South Africa
I'm writing on behalf of my husband CAA.
CAA married BJO in March 2000. Her daughter from a previous marriage had a son out of wedlock in Aug 1999. Her daughter abandoned the child on their doorstop at 4 months of age.
CAA supported BJO in the adoption of HER grandson as he was under the opinion that BJO wasn't able to adopt on her own. The adoption was granted to both in June 2000 (after 3 months of marriage). Their marriage broke down within months, and they separated in June 2001 and BJO divorced CAA in Aug 2002. She was given uncontested custody of her grandson but CAA has been made to pay full maintenance and schooling plus medical for the child. CAA agreed to this under huge duress otherwise BJO would not allow the divorce to continue.
BJO contributes nothing to the child except for accomodation.
BJO has continued to harass CAA for more money, stationary, clothing etc. CAA has had to issue a restraining order to stop the continual harrassment. We fear this will continue to affect our lives so he feels he has no option but to challenge the adoption, using "coersion" as an avenue. CAA has no contact with the child.
We have made contact with a lawyer in SA, but have not had positive response.
BJO has proved to be an opportunist (she married CAA in order to provide for her, her delinquant daughter and her grandchild) When their joint business started to fail, she filed for divorce on grounds including "having no love" for him. Her late first husband provided well for her, and she squandered the money on luxuries i.e. bought a speedboat, and continued to support her daughters delinquant lifestyle. Her late husband also left a huge trustfund for the daughter which is to be paid to her later this year 2004. The daughter is a drug addict and has been working as a prostitute since the age of 16 - hence the pregnancy. BJO refuses to use the trustfund money for the upkeep of her grandson, and insists that the money is paid to the daughter (to continue her drug dependant lifestyle.) BJO wants to keep CAA responsible for the upkeep of her grandson.
Please help us to get out of this abusive and unfair situation!

And how the heck are we supposed to help you in South Africa? This forum is for U.S. law only.

sigh..... In any event, your husband adopted the child so he is the FATHER. He doesn't have the option to walk away.
