The LA Times recently reported here on the bitter and lengthy on-going litigation involving a $400 million testamentary trust between the decedent’s third ex-wife (who also happens to be the guardian of the 13 year old boy who is the principal beneficiary of the trust) and the trustees. Battles over how an estate is administered, be it a probate estate being administered by a personal representative or a trust estate being administered by one or more trustees, are far and away the leading causes of probate litigation. These disputes are foreseeable, and can be mitigated (although not eliminated) with proper planning.
