You can change your Will without completely re-writing a new Will in Mississippi.  This can be done be preparing and executing a document called a "codicil". 

What is a codicil?  A codicil is a separate document which amends a prior Will.  A codicil may revoke a Will, or it may also revive a revoked Will.  To be valid, the codicil must be subscribed by the maker and be attested by two (2) or more credible witnesses who witness the execution of the codicil in the presence of the maker at the request of the maker.  A codicil may also be completely written in the handwriting of the maker, dated and signed at the end of the codicil.
