(1)          A partner may retire—
    
        
            | (a) |  | with                  the consent of all the other partners, | 
        
            | (b) |  | in                  accordance with an express agreement by the partners, or | 
        
            | (c) |  | where                  the partnership is at will, by giving notice in writing to all                  the other partners of his intention to retire. | 
    
 
(2)          A retiring partner may be discharged from any liability to any third          party for acts of the firm done before his retirement by an agreement          made by him with such third party and the partners of the reconstituted          firm, and such agreement may be implied by a course of dealing between          such third party and the reconstituted firm after he had knowledge of          the retirement.
 
(3)          Notwithstanding the retirement of a partner from a firm, he and the          partners continue to be liable as partners to third parties for any act          done by any of them which would have been an act of the firm if done          before the retirement, until public notice is given of the retirement:
Provided that          a retired partner is not liable to any third party who deals with the          firm without knowing that he was a partner.
 
(4)          Notices under sub-section (3) may be given by the retired partner or by          any partner of the reconstituted firm.
