Focus and practice areas

Business law is the core of what the firm does, and the other areas grow from it. Clausewitz Reyes, PLLC handles business law and business litigation, along with real estate law and commercial real estate. The firm also lists franchise law, labor and employment for employers, estate planning and probate, appellate matters, and oil and gas. That range covers much of what a company meets over its life.

For a business client, the useful part is that the transactional side and the courtroom side share one roof. The litigation group can defend a contract the business law group drafted, if a dispute later follows. In my opinion, that continuity is the practical draw of a firm organized this way.

Business, franchise, and employment work

Business law covers formation, contracts, and the day-to-day agreements a company signs. It reaches the choice of entity at the start, the operating agreement that governs the owners, and the deals a company strikes as it trades. The firm groups this general counsel work with the more focused areas around it.

Franchise law covers the agreements that bind a franchisor and its franchisees. These matters usually turn on the franchise disclosure document, the franchise agreement itself, and the registration rules a given state applies. Disputes in this area often concern territory rights, royalty terms, or the end of a franchise relationship. A firm that names franchise law as a set area tends to see owners on both sides of those deals.

Labor and employment work for employers deals with hiring, workplace policy, and the rules around ending a job. It can mean drafting a handbook, answering a wage claim, or defending a decision to let an employee go. The employer focus tells a client where the firm stands in that kind of matter.

How the team is built

Two partners lead the firm: Tiffanie S. Clausewitz and Shellie R. Reyes. Their two names together form the firm's name, a common sign in small practices that the partners stay close to the files. The firm describes itself as a small business that works closely with each client.

Each partner carries the title of partner on the firm's pages. The site does not publish a founding year. As a reviewer, I read the two-partner structure and the named practice areas as the clearest picture of how the firm is set up.

How disputes and appeals are handled

Business litigation is the part of the firm's work that reaches the courtroom. A commercial dispute usually begins with a demand or a filed complaint, moves through discovery, and ends in a settlement or a trial. Common versions include breach of contract, disagreements among business partners, and claims over unpaid work.

The firm also lists appellate work, which is the review of a trial court's decision by a higher court. An appeal turns on the written record and the legal briefs the parties file. A party that loses at trial has a set window to file, and the appeal can affirm, reverse, or send the case back. Holding trial and appellate work together lets one firm follow a matter past the verdict.

Property and estate matters

Real estate law and commercial real estate cover purchases, leases, and the documents that record them. For a company, that can mean an office lease, the sale of a building, or the title and financing steps behind a new location. The firm places commercial real estate beside general real estate, which fits a client base of businesses as well as individuals.

Estate planning and probate handle wills, trusts, and the court process that settles an estate after a death. Probate runs through a court, where an executor gathers assets, pays debts, and passes what remains to the heirs. The same partners can prepare a plan in advance and then guide a family through probate later. Oil and gas closes the list, a natural area for a firm working across South and West Texas.

Working with a small firm

The firm calls itself a small business that works closely with each client. In a firm this size, a client often deals directly with a named partner. That direct line can matter most when a business question and a personal one, such as an estate plan, reach the same office at once.

Covering many areas under two partners asks for range from each of them. The named practice areas point to a general business focus with room for the litigation and property matters a company runs into. A client can weigh that breadth against the depth a single-area firm might bring.

Who the firm works with

The firm works with individuals and businesses across the Greater South and West Texas regions, from its base in San Antonio. Serving that wide a region fits a firm whose clients include energy and property owners spread across Texas. That footprint matches the mix of business, property, and energy work on its menu.

A client choosing this firm gets two partners and a practice that spans contracts, courtrooms, property, and estates. The steady value is continuity, since one firm can hold a matter as it changes shape. The listed social profiles are Facebook, Instagram, and LinkedIn.
