What does the "Doctrine of Dependent Revocation" allow?

The "Doctrine of Dependent Revocation" applies in situations where a testator revokes a will based on the belief or intention that another will will be valid and effective. When the testator attempts to revoke their original will but mistakenly believes that the new will is valid – for example, if the new will is either lost, improperly executed, or invalid for some reason – the doctrine allows the court to disregard the attempted revocation of the original will.

This legal principle is based on the assumption that the testator did not intend for their original will to remain revoked if the new will was not going to take effect. Therefore, the doctrine acts to protect the testator's intent by allowing the original will to remain effective despite the failed attempt to revoke it.

The other options do not reflect the purpose of the Doctrine of Dependent Revocation. For instance, it doesn't pertain to automatic probating of lost wills, it doesn't allow revocation without physical evidence, and it certainly does not preserve all wills without conditions. Instead, it specifically addresses scenarios involving the interaction between two or more wills and the intent of the testator concerning their testamentary documents.
