Can I probate my will when I am alive? Should a will be registered?

With respect to my will. Should I register my will? Can I probate my will when I am alive. I have 2 children daughter and son. I have made my will in favour of my daughter. The flat that I currently own mentioned in the will has been transferred to me after my husbands passed away was purchased by my husband with his own money and is not ancestors property. I would like to protect my daughters interests such that she does not require any NOC from my son in the future in the event that my will is required to transfer the flat to her name. I have also submitted my nomination form. The nomination form that I submitted in 06-Sep-2009 was processed into the minutes of meeting on 04-05-2014 (we were never informed) and given to me last week on 27-02-2017 after my numerous follow ups over the years. I am not comfortable with this delay and hence seek answers.
