During his time as a law student in Austin, Tindall worked as a Legislative Assistant for a member of the Texas House of Representatives.

[10] Beginning in the early 1980s, Tindall began lobbying to update Texas family law, especially in the areas of community property and child support.

Tindall successfully secured passage of legislation to promote alternative dispute procedures including mediation, arbitration and collaboration.

In 1989, Tindall received an appointment to the U.S. Commission on Interstate Child Support, based on the recommendation of his Congressman, the Honorable William Archer (R–Texas).

[13] In 2015, Tindall was named Chair of the Drafting Committee for the Model Veterans Court Act, and was elected Life Commissioner to Uniform Law Commission.

[14] As a result of Tindall's lobbying efforts, Texas adopted the first collaborative law statute in the United States in 2001.

[15] This enactment marked an advance in law for families in transition and provided legally recognized means for private dispute resolution without court intervention.

Tindall was honored by the Alternative Dispute Resolution Section of the American Bar Association with the 2012 Lawyer as Problem Solver Award.

The American Bar Association honored him with this award in recognition of Tindall as "a role model for lawyers who wish to transition from litigators to peacemakers.".
