So the complicated situation is as follows.
Mr. A & Mrs. B are Christians and are married and have one daughter (Z). Mr. C and Mrs. D are Hindus and are married and have one son (X). Now, by a decree of divorce, A&B and C&D get divorced. The decree of divorce clearly gives custody of Z to Mr. A and custody of X to Mrs. D. Later on, Mr.A and Mrs. D get married under the provisions of the Special Marriage Act.
Now, Mr. A wants to adopt Mrs. D's son X and Mrs. D wants to adopt Mr. A's daughter Z. What are the appropriate legal provisions for adoption. What is the procedure to be followed ?
