Katherine Feinstein Mariano

The late senator Dianne Feinstein’s daughter, Katherine Feinstein Mariano, is (still) feuding with co-trustees of the very large estate left amid the recent passing of the politician and her longtime husband Richard Blum, and it's spilling into the courtroom. Mariano, who served as the presiding judge of the San Francisco Superior Court for 12 years until 2012, is accused of changing the locks of a Stinson Beach home from the estate and staging it for sale, against a judge’s orders, as the Chronicle reported. Other parties involved in the estate settlement include other trustees, former Blum Capital CFO Marc Scholvinck and Blum’s longtime attorney Michael Klein, as well as Blum’s three children from a previous marriage. Wealthy investor Richard Blum died in February 2022. Feinstein was the sole beneficiary of their marital trust until she died, although she appointed her daughter as power of attorney in her last few months.
