About me

Mr. Berkshire's practice focuses on all areas of domestic relations and family law matters, including appellate practice.  He has handled divorce cases of varying values from estates with a net worth in the tens of millions of dollars to single mothers with limited funds to presidents of corporations and those in between.  Mr. Berkshire focuses on mediation and settlement of disputed matters so clients have more control over the final outcome and do not spend funds on attorney's fees unnecessarily.  When settlement is not an option, Mr. Berkshire aggressively pursues his client's interests in court, including temporary child support, exclusive use of residences, and spousal maintenance.  Many cases he is involved with include the use of experts for business valuations, custody evaluations, forensic accounting, tax implications, vocational assessments, real estate appraisals, and retirement account division.  He has also successfully completed multiple family law appeals related to child support, property distribution and spousal maintenance.  As juvenile law is many times implicated in the family law arena, Mr. Berkshire also represent parties in parental rights terminations, guardianships and dependency actions. 

Although he is relatively new to the bar, Mr. Berkshire has been lead attorney on over 200 family law trials and has argued successfully in front of the Court of Appeals.  Mr. Berkshire is known by his peers to be an excellent attorney and advocate for his clients. 

Mr. Berkshire has presented lectures for moot court teams at Sandra Day O'Connor College of Law and has taught legal symposiums at the University of Arizona. 

In the area of Family Law, Mr. Berkshire represents clients with dissolution (divorce), paternity, legal separation, appeals, child custody, spousal maintenance, relocation issues, temporary orders, orders of protection, child support, post decree matters and cohabitation agreements.  When handling Juvenile Law, he assists clients with termination of parental rights, guardianships and dependency.
