Section 6124 Of Chapter 3. Revocation And Revival From California Probate Code >> Division 6. >> Part 1. >> Chapter 3.

. If the testator's will was last in the testator's possession, the testator was competent until death, and neither the will nor a duplicate original of the will can be found after the testator's death, it is presumed that the testator destroyed the will with intent to revoke it. This presumption is a presumption affecting the burden of producing evidence.
