A Will should be periodically reviewed and kept current. Keeping it current is just as important as making one in the first place. Certain changes in your life, such as marriage, birth of a child, purchase or sale of property, change in your financial status, or changes in various tax laws may warrant your making certain important revisions in your Will. Also, laws change from state to state (and country to country) so the Will should be updated to take the local laws of where you currently reside into account.
