1. IF the biological mother is declared mentally unfit and IF there are no other relatives of the mother, THEN the HC may be petitioned with the appropriate documentary facts and seek directions to the orphanage, to hand-over the child for adoption or care-taking upto majority. The applicant/s may have to submit appropriate documentary proof of financial status, good conduct and undertaking to the above affect.
2. It is true that a certified mentally retarded person cannot give any consent, BUT if there are other existing guardians / relatives of such person, then they have the first right over the child.
3. IF you can manage to trace the relatives of the above unwed mother, THEN they can stake claim over the child for further growth of the child. In such cases, whether relatives exists and are willing, THEN even the orphange has to mandatorily trace such relatives and hand over the child to such relatives and here the orphange cannot retain the child in custody.
4. Apart from sentiments & emotions (which are usually short lived), socially & logically it would be better to trace the unwed mothers family / boyfriend and arrange for them to take over custody of the child. OF course, you may sponser the childs study and expenses, if you wish to retain the sentiments and emotions.
