If you need to change your executor, you may do so by writing a "codicil" to your Will. Basically, this is an amendment in which you name your new executor (and back up if you have one). You may handwrite it or type it. Use a separate sheet of paper and write the change using the same wording used to name your original executor in your Will. You must sign your codicil in the presence of at least 2 witnesses, although you do not have to use the same witnesses as used for your Will. Attach the signed and witnessed codicil to your Will and keep it in a safe place; you may wish to tell your new execuator where to find it. Or you can have an attorney do this for a nominal cost. Finally, if you have other changes that need to be made (and the older the Will, the more likley it is that changes are needed), you can draft and execute an entirely new Will. You can also have an attorney do this or get an on-line form and do it yourself.
