Practice areas

Six areas of commercial litigation we handle for businesses.

When disputes threaten your business, you need a legal team that acts quickly. We resolve complex civil and commercial matters in the Magistrate’s and High Courts, and work with leading advocates when the matter requires it.

01

Breach of Contract & Debt Recovery

Enforcing contractual rights, pursuing payment, and recovering what your business is owed under written and oral agreements.

02

Shareholder & Partnership Disputes

Resolving deadlock, director liability, and shareholder deadlocks before they derail the business. Negotiation, derivative action, or contested exits.

03

Business Rescue & Liquidation Litigation

Acting for companies in financial distress, business rescue practitioners, and creditors in formal insolvency proceedings and disputes.

04

Urgent Court Applications

Interdicts, spoliation orders, and other urgent relief where delay would cause irreparable harm. We move on the same day where the matter requires it.

05

Professional Negligence & Liability Claims

Claims against professionals and advisors for negligent advice, misconduct, or breach of duty. Defending claims where your business is the target.

06

Arbitration, Mediation & ADR

Alternative dispute resolution where litigation is not the right route. Mediation, arbitration, and structured settlement to preserve commercial relationships.

Our approach

Practical, results-driven outcomes not theatre.

We focus on achieving practical, results-driven outcomes that protect your position and preserve your business relationships. At every stage, we work to minimise both reputational damage and financial risk, allowing you to move forward with confidence and stability.

01

Legal clarity, business sense

Strategy that reflects how your business actually operates - not just what the law allows.

02

Personalised service

You work directly with the attorneys running your matter. No call centre, no juniors passing notes.

03

Strategic collaboration

We work with leading advocates where the matter requires it, so you get the strongest courtroom representation.

04

Risk & reputation awareness

Every step considers the cost, the publicity, and the relationship consequences - not just the legal argument.

When the stakes are high, you need a legal partner who understands urgency, complexity, and risk. We provide clear direction, strong representation, and strategic insight to protect your position and move you forward.

Responsive

Reason 04

Common questions

Answers before you ask.

Short, honest answers. If you have a question that isn’t covered here, just email Khethu and we’ll come back to you the same day.

Ask us directly
For urgent applications (interdicts, spoliation orders, and similar), we move the same day the matter is instructed. Email or WhatsApp the office with a short summary and we’ll get back to you within hours.
No — a short written outline of the matter is enough for the first call. We’ll tell you exactly what to bring (or send) to the paid consultation based on the type of dispute.
The first paid consultation is a fixed fee agreed in advance. Once the matter is instructed, a written mandate sets out the fee structure (hourly, capped, or contingency where appropriate) and the deposit required to start work.
We appear in the Magistrate’s Court and the High Court of South Africa. For specialist matters that require senior counsel, we instruct and work with leading advocates.
We are based in Sandton and focus on Gauteng, where most of our commercial litigation work originates. Matters outside Gauteng can be discussed on a case-by-case basis.
Email Khethu with a one-paragraph summary. If commercial litigation is the right fit, we’ll tell you. If it isn’t, we’ll suggest the right next step — even if that means referring you elsewhere.
