If it's a 2001 will, it has to be California. (I don't think STern can make that in a day trip......LOL)
But.....doesn't she have a ranch in Texas that Marshall gave her? Perhaps she named that as her permanent residence.
I'm almost *certain* she didn't.
It was not to her benefit to live in TX or have a residency here. All the TX court rulings had gone against her in Marshall and it was all over.
Only CA and the Supremes had given her any chances, so I'm sure she had to stay in CA - because the only award she had gotten was because of her bankruptcy in CA.
