Co-Founder Dispute Heading to Court? Your First Move

Your co-founder has lawyered up. There are demands flying about share allocation, IP ownership, breach of fiduciary duty, alleged misuse of company funds, or oppression of minority shareholders. A formal letter has arrived — or you have heard proceedings are imminent. The instinct is to fire back. Don’t. The first 14 days will set the tone, the documents, and often the outcome of the entire dispute.

The legal landscape

Co-founder disputes typically engage several overlapping bodies of law: directors’ duties under sections 180–184 of the Corporations Act 2001 (Cth), oppression remedies under sections 232–234, fiduciary duties at general law, the company’s constitution and any shareholders’ agreement, and often IP assignment and confidentiality obligations. Where a shareholders’ agreement exists, it usually contains a dispute resolution clause (mediation, then arbitration or court) that must be followed.

Do not admit anything in writing

The single most damaging thing in a co-founder dispute is the casual email or Slack message conceding a fact: “yeah I knew about that”, “you were probably right”, “I should have told you”. Each one becomes evidence. Until you have responded properly with structured legal framing, every communication should be either silent or carefully drafted. Apologies, partial concessions, and informal settlement offers all create exposures that are very hard to walk back.

Common pitfalls in the first weeks

• Locking the other founder out of systems. Often a breach of directors’ duties and the constitution; can attract injunctive orders against you.
• Transferring assets or IP. Easily characterised as oppression or breach of fiduciary duty.
• Hostile board meetings called on short notice. Procedural defects make decisions challengeable under section 1322.
• Discussing the dispute with staff or investors casually. Defamation and breach-of-confidence exposures.
• Self-representing without structure. Court proceedings against startup founders proceed in commercial lists with strict pleading rules.

What a proper response does

A formal Legal Response acknowledges receipt, denies the allegations on a without-prejudice basis, demands full particulars (specific dates, decisions, transactions, statements), invokes any dispute-resolution mechanism in the shareholders’ agreement, reserves all rights including counterclaims, and signals you understand the law of directors’ duties and oppression remedies. It positions you for negotiation, mediation, or litigation — without conceding anything.

What Claim Done delivers

For a flat fee, Claim Done drafts a Legal Response calibrated for co-founder and shareholder disputes — citing the Corporations Act framework, framing the right defences, and demanding the particulars that often expose weaknesses in the other side’s claim.

What happens after

A properly-framed response puts your position on record before formal proceedings are filed. If court is inevitable, your response forms the spine of your defence and counterclaim.
