Dear

According to the information it's good that your father's name is consistent in your class 10 and 12 marksheet and JEE admit card, but having a different name in the income certificate might cause some issues during the REAP counseling process.

To avoid any problems, I recommend contacting the REAP counseling cell or the respective authority handling the process. Explain the situation and provide all necessary documents, including the income certificate and any other relevant paperwork that shows the name change. They might ask for additional documentation or verification to resolve the discrepancy.
