Legal Question in Wills and Trusts in California

You need to contact a probate attorney without delay, unless the trust was created after the dissolution was final, the ex-wife's interest in the trust was revoked by the entry of the judgment of dissolution. As well, by destroying the original and copies he may have revoked the trust as well.

I do agree that you need to consult with a probate attorney right away. Under California law, the will was revoked as to the ex-wife when the divorce judgment was entered. However, the same may not be true for the trust. But, if your brother destroyed the original, that may be a sufficient act to express intent to revoke the trust. In any event, this will need to brought in front of a probate judge sooner rather than later to assure the ex-wife doesn't start taking property.
