Dissolution of a partnership firm can occur in several circumstances:
1) When the term of the partnership expires or the particular venture is completed.
2) Upon the death, insolvency, or retirement of a partner.
3) When the court orders dissolution due to a partner's misconduct, transfer of their interest without consent, disability, or if continuing the business would result in losses.
Dissolution of a partnership ends the legal agreement between partners, while dissolution of a partnership firm ends the business entirely through settling assets/liabilities and discontinuing operations.
