Travel for deposition

[BudHerman]

What is the name of your state (only U.S. law)? Arizona and California. I am involved in a dispute regarding the AB Trust established by my parents. My father died in 2003 and my mother died in 2009. Between the time of my father's and my mother's deaths, my brother [the only other beneficiary of the trust] took extreme financial advantage of our mother. He and his girlfriend quit their jobs, moved into a house owned by the trust near to my mother's house, arranged to have all of their utilities paid electronically from mom's account, used mom's credit cards for, among other things, internet porn [165 seperate instances at around $50 a pop], pay per view porn, Las Vegas hotels casinos massage parlors and strip clubs, and 58 seperate shopping trips to 12 different Las Vegas area Walmarts during one seven day span for the purpose of buying chemicals used in the manufacture of crystal meth. Additionally, my brother would have Mom write him about $50,000 dollars a year in checks until her death. A highly regarded handwriting expert has tentatively identified 14 of the checks written to my brother as forged. This was all done under the guise of "taking care of Mom at her request". My mother breached the terms of the trust by completely ignoring them. She did not establish the irrevocable B Trust upon the death of Dad as required. This is all background information for my question. In order to make sure there is something left to collect should we receive a judgement in our favor, we have filed a "Lis Pendens" lein on my brother's two Arizona properties. His lawyer has countered by filing a criminal complaint against me. We have petitioned the court to delay any further action until the resolution of the California case. Now, however, my brother's lawyer has sent to my wife and I Notices of Deposition in the Arizona case. This was done purely for harassment. He knows we have no information requiring a deposition. Additionally, he has demanded that my wife and I appear at his office, 350 miles away from our residence in San Diego, three days apart. My wife has nothing to do with this and has no relevant information. My question: Can he do this?
