Hawaii does not require a revocable living trust to be notarizedHRS Ch. 554D (Uniform Trust Code)Verified Jul 15, 2026View source. Hawaii allows transfer-on-death deeds for real estate, enabling property to pass directly to named beneficiaries without probate. This is a significant probate avoidance tool that doesn't require creating a trust. Transferring property into a revocable trust does not trigger a property tax reassessment in Hawaii, so property taxes remain at their current level.

Hawaii automatically revokes an ex-spouse as beneficiary on life insurance, retirement accounts, and similar designations upon divorce. However, these automatic revocations can be overridden by a divorce decree or by re-designating the ex-spouse after the divorce.

Hawaii authorizes remote online notarization (RON), allowing trusts, healthcare directives, powers of attorney to be notarized via video call from anywhere. However, wills are excluded from RON and still require in-person notarization.
