About ALL Trial Lawyers

Southern California’s trusted firm for juvenile dependency defense, CPS defense, and criminal defense. Founded by Mo Abuershaid, Esq. — a former Orange County Public Defender and annually certified juvenile dependency practitioner with over 10,000 dependency and criminal matters handled. Over 50 years of combined legal experience, having successfully litigated over 75+ trials and 150+ preliminary hearings.

Who We Are

ALL Trial Lawyers is a Southern California trial firm built around one principle: when your family, your freedom, or your future is on the line, you need a lawyer who shows up. We defend parents facing CPS investigations and juvenile dependency petitions, individuals charged with misdemeanors and serious felonies, and victims of serious injury throughout Orange County, Los Angeles County, Riverside County, San Bernardino County, and San Diego County.

Our founding attorney, Mohammad “Mo” Abuershaid, began his career at the Orange County Public Defender’s Office and has gone on  to represent many celebrities and to handle over 10,000 dependency and criminal matters. He is admitted to practice in every county in California and is certified annually as a juvenile dependency practitioner — a credential held by only a small group of attorneys in the state.

We represent clients from every walk of life. We believe that every person deserves aggressive, strategic representation — regardless of financial situation, background, or the nature of the allegations. That belief is the reason this firm exists.

Meet the Founding Attorney

Mo Abuershaid, Esq.

Mo is one of California’s most recognized authorities in juvenile dependency and CPS defense. After earning his Juris Doctor from Western Michigan University in 2014, he joined the Orange County Public Defender’s Office, where he represented thousands of clients in criminal and juvenile matters. That foundation — understanding exactly how government agencies build cases — is what makes his defense work so effective today.

Mo has personally handled more than 2,000 juvenile dependency matters involving general neglect, failure to protect, sexual abuse allegations, physical abuse, shaken baby claims, positive toxicology in newborns, medical abuse or misdiagnosis, and wrongful accusations. He represents parents in juvenile dependency courts throughout Orange County, Los Angeles County, San Bernardino County, Riverside County, and nearly every region in California.
