Marium Siddiqui
Founder and Principal Attorney
Texas Attorney · LL.M. in Taxation · Texas Bar No. 24083849
Marium Siddiqui is the founder and principal attorney of The Siddiqui Law Firm, PLLC, a Houston business-law practice serving privately held companies, real estate owners and investors, founders, professionals, and institutional transaction participants.
Her practice is built around the legal events that shape a business over time: formation, ownership and governance, commercial contracting, acquisitions, leasing, financing, investment, employment, succession, and dispute resolution. She represents clients ranging from emerging technology companies and first-time founders to family-owned enterprises, franchisees, multi-location operators, real estate sponsors, professional practices, and multinational corporate groups.
Marium’s transactional practice includes commercial real estate acquisitions and dispositions, asset and equity purchases, membership-interest transfers and buyouts, title and survey diligence, landlord- and tenant-side commercial leasing, property-management arrangements, and institutional refinance transactions. She also serves as Texas and U.S. counsel in secured and cross-border credit facilities, preparing authority and enforceability opinions, analyzing UCC perfection, coordinating collateral packages, and implementing lender-required entity and governance structures.
As outside general counsel, Marium advises companies on the documents and systems required to operate and scale. Her work includes entity and holding-company architecture, operating and partnership agreements, founder and investor arrangements, customer and vendor contracts, intellectual-property ownership and licensing, intercompany agreements, executive-compensation and incentive arrangements (including phantom-equity, key-employee, and bonus and commission agreements), employment, contractor, and restrictive-covenant documentation, subscription and platform terms, privacy and data provisions, and governance protocols.
Her client base reflects the breadth of that work. She has advised family-owned and multi-location businesses; restaurant, bar, food-truck, hospitality, and recreation operators; franchise businesses; technology, SaaS, AI, digital-platform, and wellness startups; hemp and regulated-product businesses; commercial property owners and tenants; physicians and other professionals; and borrowers and guarantors navigating institutional and SBA-supported financing.
Marium also serves as lead counsel in commercial disputes involving contracts, fiduciary duties, ownership and governance, partnership and member conflicts, commercial leases, guaranties, lender compliance, construction and property issues, and first-party property insurance claims. Her litigation practice informs her transactional drafting: agreements are structured with attention to the arguments, ambiguities, evidentiary gaps, and enforcement problems that arise when business relationships deteriorate.
The combination is deliberate. Clients do not have to choose between a deal lawyer who understands the transaction and a litigator who understands the dispute. The same attorney who structures the entity, negotiates the lease, or drafts the operating agreement can identify where the document will hold—and where it must be strengthened before anyone signs it.
Education and Early Professional Development
Marium earned her Bachelor of Arts in English from The University of Texas at Austin in 2009. She received her Juris Doctor from South Texas College of Law Houston in 2012. During law school, she served as an Associate Editor of the Corporate Counsel Review, participated in the Board of Advocates’ alternative-dispute-resolution program, and competed through the Frank Evans Center for Conflict Resolution.
After law school, Marium joined JPMorgan Chase in Houston, where she worked from 2013 through 2016 as a KYC/AML Due Diligence Analyst and Quality Control Analyst. She conducted enhanced due diligence, regulatory-risk assessments, and quality-control review under BSA/AML, OCC, and OFAC frameworks. That experience inside a global financial institution continues to inform her approach to institutional finance, beneficial-ownership review, investor onboarding, sanctions and risk controls, and compliance-sensitive business structures.
Marium earned an LL.M. in Taxation from the University of Houston Law Center in 2015. Her graduate tax training supports her work on entity selection, reorganizations, ownership transfers, executive compensation, succession, investment structures, and transactions requiring coordination among legal, tax, accounting, and finance professionals.
Career
Marium was admitted to the State Bar of Texas in 2012 and to the United States District Court for the Southern District of Texas in 2018.
Following her work at JPMorgan Chase, she entered private practice and in 2017 became a founding partner of the firm later known as Siddiqui & Do, PLLC. She developed a practice spanning business transactions, commercial real estate, finance, private-company advisory, litigation, and tax-informed planning. She now leads The Siddiqui Law Firm, PLLC as its founder and principal attorney.

“Most legal work fails quietly, years after it was signed. I run this practice against that failure mode: complete instruments, documented systems, and one attorney accountable for the work from structure through resolution.”
Marium’s practice emphasizes complete instruments, documented workflows, disciplined version control, and direct attorney responsibility. She also develops structured, technology-assisted legal systems intended to improve factual verification, document consistency, institutional knowledge, and quality control while preserving attorney judgment over every legal determination.
