How often should I review and update my will after a major life event?

Review your will after any major life change and otherwise every three to five years. The classic triggers are marriage, divorce, the birth or adoption of a child, the death of a beneficiary or named executor, a large change in assets, or a move to a new state, since estate laws are state-specific. Divorce is especially important: many states automatically revoke gifts to an ex-spouse, but not always the appointment of their relatives, so review everything. Even without a life event, tax laws and your relationships evolve. A quick reread every few years ensures your executor, guardians, and beneficiaries still reflect your wishes. Keep prior versions clearly marked as revoked to avoid confusion during probate.
