Michelle May O'Neil has 27 years’ experience representing small business owners, professionals, and individuals in litigation related to family law matters such as divorce, child custody, and complex property division. Described by one lawyer as "a lethal combination of sweet-and-salty", Ms. O'Neil exudes genuine compassion for her client's difficulties, yet she can be relentless when in pursuit of a client's goals. One judge said of Ms. O'Neil, "She cannot be out-gunned, out-briefed, or out-lawyered!"

Family Law Specialist

Ms. O'Neil became a board-certified family law specialist by the Texas Board of Legal Specialization in 1997 and has maintained her certification since that time. While representing clients in litigation before the trial court is an important part of her practice, Ms. O'Neil also handles appellate matters in the trial court, courts of appeals and Texas Supreme Court. Lawyers frequently consult with Ms. O'Neil on their litigation cases about specialized legal issues requiring particularized attention both at the trial court and appellate levels. This gives her a unique perspective and depth of perception that benefits both her litigation and appellate clients.

Top Lawyers in Texas and America

Ms. O’Neil has been named to the list of Texas SuperLawyers for many years, 2011-2018, a peer-voted honor given to only about 5% of the lawyers in the state of Texas. In 2014-2018, Ms. O'Neil received the special honor of being named by Texas SuperLawyers as one of the Top 50 Women Lawyers in Texas, Top 100 Lawyers in Texas, and Top 100 Lawyers in DFW. She was named one of the Best Lawyers in America for 2016 and received an "A-V" peer review rating by Martindale-Hubbell Legal Directories for the highest quality legal ability and ethical standards.

Author and Speaker

A noted author, Ms. O'Neil released her second book Basics of Texas Divorce Law in November 2010, with a second edition released in 2013, and a third edition expected in 2015.  Her first book, All About Texas Law and Kids, was published in September 2009 by Texas Lawyer Press. In 2012, Ms. O’Neil co-authored the booklets What You Need To Know About Common Law Marriage In Texas and Social Study Evaluations.  The State Bar of Texas and other providers of continuing education for attorneys frequently enlist Ms. O'Neil to provide instruction to attorneys on topics of her expertise in the family law arena.

In 2017, the Dallas Court of Appeals quietly and with zero fanfare released the In re Sting Soccer opinion. It is an unpublished memorandum opinion, but it chocks a huge, unexpected punch to discovery-as-we-knew-it.

The Texas Supreme Court has released new discovery rules that will be effective January 1, 2021. While these rules are still under review and subject to change, they are so significant that they warrant review now even

The United States Supreme Court has moved a giant leap forward in LGBTQ+ rights with the latest opinion in Bostock v. Clayton County, Georgia. To say this is a HUGE deal is an understatement. In 2015, when the Court solidified same-sex marriage, that right only applied to a smaller subset of people who wanted to

Most of the country is under a lockdown due to the Coronavirus pandemic. A lot of people are out of work, barely making ends meet, and are struggling to collect unemployment. There was a great relief when the President announced that every tax-paying citizen would receive a stimulus check in this time of crisis. However,
