Please pay more attention to posting guidelines. There is a Read First sticky in the Adoption forum (where this was moved from) that directs questions of a legal nature to this forum.

The answer to your question is yes. In a step-parent adoption, the current legal parent must relinquish their rights.

Start lawyer shopping. Get one that handles adoptions and go through the courts. Is the father a danger to the children ? If not then he may be able to stop the adoption.
