No, wills are perpetual by nature, which means once the testator proofs and validates his will, it will never terminate. A will can never actually “expire,” and there is no restriction that limits the time during which a will is still valid. The only way a last will and testament becomes invalidated is when the testator revokes all previous wills, in their current will. There are also additional restrictions on the time during which the executor of the will can initiate probate. Even though your will may still be valid, it is important to remember that your will may no longer be suitable for your needs. Your circumstances may have changed significantly since you prepared the will. For example, you may have since got married, or divorced, one of your beneficiaries may have passed away or you may have acquired substantial assets not covered by your will.
