Then the Soviet Union refused to release Korchnoi’s family

I have always had questions about this point.

Korchnoi's adopted non-biological son was drafted into the Army and
sent to Siberia. It seems doubtful that Korchnoi had a valid claim.
How did Korchnoi come to adopt this son? Do you know?

Korchnoi's wife sued him as soon as she was allowed to immigrate and
arrived in Switzerland. Do you know what happened to that case?
