What this means in practice

This Act matters when two or more people carry on business together with a view to profit and have not put a company or LLP structure in place. The practical risk is that a partnership can exist even without a document called a partnership agreement. That can affect authority, profit shares, debts, exits and who is responsible when one partner signs or promises something.

Key points

  • A partnership can be created by conduct, not just by signing a formal agreement.
  • Each partner's authority should be clear before the business signs customer, supplier or finance documents.
  • Exit rules are usually cheaper to agree while everyone still trusts each other.
