Retirement by conduct in partnerships; no retirement deed

• Lady joins partnership firm via reconstitution deed.
• After she was married à made to retire
• But no retirement deed
• But lady did not interfere with work for 20 years – before/after retirement
• Form O submitted a few years later by company in 2013
• But there exists a REGISTERED partition deed where she affirms she retired.

Now lady alleging by filing a suit in 2017 that;

1. I did not retire.
2. I didn’t sign any document.
3. I was told bits and pieces and was told I was still part of the firm.
4. Firm made me sign bogus documents.

Issues;

1. Can there be retirement by conduct.
2. Is a retirement deed necessary?
