According to Indian law, your first legal heir will decide whether to donate your organs during death. Even if you have pledged your organs by registering with National Organ and Tissue Transplant Organisation(NOTT), donation cannot be carried out, unless legal heir gives their consent. Therefore, you need to pledge/register to be an organ donor with NOTT and it is very important that you inform your wish to donate your organ or body with your family much early. It will enable your family to proceed with donation rather than last minute surprise.
