Keystone Law Group PC

Shawn S. Kerendian founded Keystone in 2014 to fill a specific and somewhat ambitious niche — to create a boutique practice focused solely on probate litigation and administration, and provide services to this underserved market. Creating Keystone was not just a passion for Shawn; it was also a strategic move. This segment of society has more wealth and is passing down more assets than previous generations.Rather than expanding to estate planning and related areas of law, Shawn kept Keystone’s mission focused on probate litigation and administration matters in order to cultivate a deeper understanding and a greater level of expertise in this specialty.While recent laws regarding trusts and estates have opened up new areas for potential disputes, contesting wills and trusts remains notoriously tricky. While many firms shy away from these challenging cases, Shawn created his firm to serve as the keystone for those seeking support for their complex probate needs.With more than 40 full-time employees consisting of seasoned probate attorneys and a dedicated team of support staff, Keystone has grown to become one of the largest — if not the largest — firms in California focused exclusively on probate litigation and administration.We represent trustees, executors, administrators, heirs, beneficiaries, creditors, guardians, and conservators in virtually any dispute that may arise in the context of a person’s death or incompetency, including:Will and trust contestsEnforcement of beneficiary rightsFinancial elder abuse claimsPetitions to recover trust and estate assetsProsecution and defense of fiduciary misconductConservatorship litigationProbate administration
