Praise be to Allah.
      Firstly: 

    Putting money in riba-based banks is a haraam action, and 
    there is no concession allowing it except in cases of necessity; in such 
    cases it should be limited to putting it into a current account without 
    taking any interest on it. This has been discussed previously in the answer 
    to questions number 104349,
    23346,
    49677. 

    Secondly: 

    The riba or interest that is received from putting money in 
    the bank is riba which is haraam. Hence you have to get rid of it by 
    spending it on various charitable causes. The owner of the money does not 
    have the right to use it for his personal benefit or for the benefit of 
    those on whom he is obliged to spend, such as his parents, children and 
    wife. 

    But if your relatives are those on whom you are not obliged 
    to spend, such as if they are your siblings or other relatives, there is 
    nothing wrong with paying it on their behalf as fees to register them in 
    school. There is also nothing wrong if you give this interest to them to 
    spend it on their various needs, especially since they are poor and needy.
