Mobina A. Zendeh Del

Mobina A. Zendeh Del co-founded The Zendeh Del Law Firm, PLLC, which operates as Zen Law Firm, in 2008 with her husband and law partner, Jason A. Zendeh Del. She leads the firm’s Social Security disability practice. Over more than 20 years in practice, she has built a practice focused on representing people whose disabling conditions prevent them from working.

Before co-founding the firm, Mobina was the lead attorney for the Dallas office of a national Social Security disability firm, where she helped build the office to include additional attorneys and support staff. She has handled thousands of Social Security disability matters for claimants nationwide.

Social Security Disability

Many Social Security disability claims are denied at the initial application stage. An initial denial does not necessarily mean the claimant is ineligible for benefits, and Social Security provides multiple levels of administrative review before a claimant reaches federal court.

Mobina represents claimants at every stage: the initial application, reconsideration, the hearing before an administrative law judge, the Appeals Council, and federal court. The practice covers SSDI and SSI, benefits for family members, and widow and survivor claims, for claimants at every age and work history.

Medical evidence is at the center of a disability claim, but the records have to be evaluated under the standards the Social Security Administration actually applies. That means understanding which records matter, how the agency evaluates functional limitations and residual functional capacity, how age and work history affect the analysis, and where a claim may be vulnerable before the hearing rather than after it. Having handled thousands of disability matters, Mobina knows what to look for in a file long before a hearing date is set.

Federal Court Appeals

When the Appeals Council denies review, the next step is a civil action in federal district court.

Social Security permits qualified non-attorney representatives to assist claimants during the administrative process. Representation of a claimant in a federal civil action requires an attorney admitted to practice before that federal court. A claimant represented administratively by a non-attorney therefore needs new counsel if the case reaches federal court.

Mobina is admitted in the U.S. District Court for the Eastern District of Texas and the U.S. District Court for the Northern District of Texas. Because she handles both administrative disability matters and federal appeals, she understands the record from both perspectives: how it is developed before the agency, and how that same administrative record will later be reviewed by a federal court.

Professional Leadership

Mobina served as president of the Dallas Association of Social Security Claimants Attorneys from 2012 to 2014 and is a member of the National Organization of Social Security Claimants’ Representatives, the national bar association for attorneys who represent disability claimants. She is a member of the College of the State Bar of Texas. She has served as a legal consultant to media outlets on disability issues, and she is recognized by judges in the Social Security field as a seasoned veteran of the practice.

Background

After earning a Bachelor of Business Administration from Southern Methodist University with double majors in Finance and Marketing, Mobina attended South Texas College of Law Houston, where she was recognized as a distinguished student and competed in both Mock Trial and Moot Court. During law school she worked in the Harris County District Attorney’s Office, and she met her husband and future law partner there.

She began her career as an associate at a family and commercial litigation firm before moving to Dallas and joining the national disability firm where she led the Texas office. She is a long-time resident of North Dallas.

Frequently Asked Questions

Is Zen Law Firm the same as The Zendeh Del Law Firm?

Yes. The Zendeh Del Law Firm, PLLC is the firm’s legal name, and Zen Law Firm is the shorter name it uses publicly. They are the same firm, the same attorneys, and the same Plano office. The firm was founded in 2008 by Jason A. Zendeh Del and Mobina A. Zendeh Del and is located at 7600 San Jacinto Place, Suite 200, Plano, Texas 75024.

Does Mobina handle Social Security disability claims outside Texas?

Yes. She has represented claimants nationwide throughout her career. Social Security disability is a federal program, and hearings are frequently held by video or telephone, so representation is not limited to the state where the claimant lives.

My disability claim was denied. Is that the end of it?

No. Many initial applications are denied, and Social Security provides multiple levels of review after an initial denial: reconsideration, a hearing before an administrative law judge, review by the Appeals Council, and a civil action in federal district court. Each stage has its own deadline, and missing one can require starting the application over.

Will Mobina personally handle my hearing?

The firm’s disability practice is led by Mobina, and hearings are handled by the firm’s attorneys. The firm can continue representing a claimant through the administrative process and, when appropriate, into federal court.

What happens if the Appeals Council denies my claim?

The next step is a civil action in federal district court. Social Security permits qualified non-attorney representatives during the administrative process, but representation in a federal civil action requires an attorney admitted before that court. Mobina is admitted in the Eastern and Northern Districts of Texas and handles these appeals.

How much does it cost to have a lawyer handle a Social Security disability claim?

Attorney fees in Social Security disability cases are governed by federal law and must be approved by the Social Security Administration. They are generally paid out of past-due benefits if the claim is approved. We will explain exactly how the fee works before you sign anything.

How long does a Social Security disability claim take?

It varies by stage and by the local hearing office’s backlog, and it is often measured in months rather than weeks, particularly between a hearing request and a hearing date. Certain circumstances, including dire need situations, can support a request to expedite. We can give you a realistic timeline once we see where your claim stands.

What conditions qualify for Social Security disability?

There is no single list that answers this. The agency evaluates whether a medically determinable impairment prevents substantial gainful activity, considering the medical evidence and the claimant’s age, education, and work history. Physical conditions, mental health conditions, and combinations of impairments can all support a claim, and the strength of a claim usually turns on the medical documentation rather than the diagnosis alone.

Where is the firm located?

The firm is headquartered in Plano, Texas, with offices in Fort Worth and San Antonio by appointment. The disability practice represents claimants nationwide.
