A Will or Last Will and Testament is a written document in which you set out how you want your assets to be distributed upon your death and who you want to manage your estate. The Will may also contain other declarations of your desires as to what is to be done with your assets.
Provided certain legal requirements are met, you may change your Will at any time.
There are strict legal requirements to creating and executing a Will. If the legal requirements are not followed, the Will may be deemed invalid.
