Business disputes rarely affect just one thing.
The matters that reach Tina's desk usually start as one of these. Each one carries a business decision before it carries a legal one.
- 01A business partner is withholding money or informationDistributions stop, the books close, and the person you built the company with stops answering. Texas law gives owners real rights to records and to a remedy.
- 02A major customer or vendor has breached a contractAn unpaid invoice, a canceled order, a supplier that walked away. What you can recover, and how fast, depends on the contract and on the first moves you make.
- 03Your company is being threatened with litigationA demand letter, a lawyer's call, a deadline. Most threats are best answered with a measured, well-informed response, not silence and not a counterattack.
- 04A former employee is accused of taking confidential informationCustomer lists, pricing, source files. Trade secret and non-compete law moves quickly when it moves at all, so the first days matter.
- 05A construction project has a significant payment disputeLiens, retainage, change orders, a general contractor who was paid and did not pay. Texas lien law runs on deadlines that do not wait.
- 06A shareholder or investor believes misconduct has occurredSelf-dealing, misrepresentation, money that cannot be traced. Fiduciary duty and fraud claims have specific elements and specific remedies.

Litigation is a means to a business end. Tina's work starts with the end you need and works back to the steps that get there.
Sophisticated commercial matters
Contract, partnership, fiduciary, fraud, construction, trade secret and investment disputes, in state and federal court and in arbitration.
Both sides of the table
Tina represents plaintiffs and defendants, businesses and individuals. Knowing how the other side builds its case changes how you build yours.
High-stakes experience
Her firm-published experience includes class actions, federal jury trials and multi-party payment disputes. Each matter is judged on its own facts.
Risk measured in business terms
Exposure, cost, time, distraction and relationships are weighed before a strategy is recommended, not after.
Negotiate when it serves you, litigate when it does not
Many matters start with a demand letter and end in a settlement. Some need a courtroom. The judgment is in knowing which is which.
A business decision first
Litigation decisions are business decisions.
A dispute costs more than legal fees. Before recommending a course, Tina looks at what the fight itself would cost the company and whether there is a shorter road to the same result.
Leadership attention
Owners and executives who spend their weeks on a lawsuit are not spending them on the business. Strategy should protect their time, not consume it.
Cash flow
Money tied up in a dispute, money spent pursuing it and money at risk in it are three different numbers. Each one matters to the decision.
Relationships and partnerships
Some counterparties will be partners again once the dispute ends. The approach should leave that possible where it is worth preserving.
Confidentiality
Court filings are public. Protective orders, sealing and the choice between court and arbitration decide what the market learns.
Reputation and continuity
Customers, lenders and employees read a dispute as a signal. The way it is handled is part of the message.

Insights
Plain-English guides to the questions business owners ask before they call a litigator.
Shareholder, Partnership & LLC Disputes
My Partner Is Taking Money From the Company. What Can I Do?
Secure the evidence, demand the records in writing, then choose the claim: fiduciary breach, conversion, civil theft, fraud or an accounting. Courts can stop the bleeding fast.
Demand Letters & Pre-Litigation
Someone Sent My Business a Demand Letter. Should I Respond?
In most cases, yes: a measured, deliberate response protects you better than silence. The real decision is who responds, when, and what the letter should and should not say.
Contracts & Breach of Contract
A Customer Owes My Company a Large Unpaid Invoice. What Now?
Gather the paper, present the claim in writing, then negotiate or sue. Texas gives unpaid vendors interest, a sworn-account pleading, and fees if the claim was presented first.
Employer Disputes & Non-Competes
Is My Non-Compete Enforceable in Texas?
Yes, if it was part of an otherwise enforceable agreement and its time, territory and scope are no broader than needed to protect the company. Here is the two-part Texas test.
Litigation Process, Fees & Risk
How Much Does a Business Lawsuit Cost in Dallas?
No honest lawyer can quote a total on day one. The cost is set by the discovery level, the motions, the experts, the court and the other side. How each one moves the number.
Arbitration, Mediation & Settlement
Should I Settle or Go to Trial?
Settle when the certain payment beats the probable judgment after fees, time, collection risk and appeal. Try the case when it does not, or when more than money is at stake.
A dispute can change the direction of a business. Your next step matters.
Describe your situation in a few sentences. Tina reviews every inquiry personally to determine the appropriate next step, usually a short call. Sending a message does not create an attorney-client relationship.
