Yes, you can adopt the relative child. It is important to contact the adoptive agencies and finalize the contract with your relative for the adoption. This type of adoption is called as the identified adoption or designated adoption.
I thing you do not need study or survey before adoption but the adoption agencies perform the survey as basic procedure to complete the process. It is one of the important complete the documentation to complete the procedure. You must have to get the details of prequalification.
I think adoption process is similar as other types of process, you just have to follow the guidelines either it is identifies or non-identifies adoption. The adoption of relative child may become easy because the adoption agencies easily get the information from the adoptee.
