DearCustomer- There is really no way to tell you when a will needs to be updated since everyone's situation is different. A will is valid until a person dies so if it is never updated it still is a valid will regardless of when it was executed.
The general rule is that a will should be updated when there is a significant change in the life of the testator. Marriage, divorce, childbirth, tax laws, and family member's deaths are some of the more obvious reasons that a will should be reviewed. Whenever one of these events occur there may be a need to review but not necessarily change a will.
If a small change is needed the testator can have a codicil added to the will without having the entire will rewritten. The best way to know if a will needs to be updated is to be aware of significant changes in you family situation. It certainly doesn't hurt to have the will reviewed every few years even without significant changes. Sometimes the tax laws are changed that can affect an estate so that is something that can happen that you may not be aware of as easily as a change in your immediate family.
