Registered and unregistered will

A registered will was executed by my mother during March 1993 to have equal share to me (daughter) and to my husband on her property, which purchased by her. My mother expired on 20.11.1998. After her death, the schedule in the registered will was given effect from 21.11.1998. My husband died on intestate 20.08.2000. Subsequent to this, my First and Second son produced a unregistered will signed by Notary before the court, during August .2001 (Reported to be written by my mother during on 23.05.1998. In the Second will no reason is recorded for deleting my husband and at the same time, a reason is recorded why no share was given to my Third son (ie) he married a Irish lady. The Second will reported to be traced and find out by my First son during April 2001. In as much as, effect to the registered will was given effect on 20.11.1998, whether the unregistered will which reported to be find out only during April 2001 and produced before the court only during August 2001 will cancel the earlier action taken on 21.11.1998 as per the registered will.
