Sir,
this is a business started by my granfather (A).in cource of time he took his three sons as partners in this firm.On his death the three brothers made new partnership deed wherein the names of A was deleted and the three of them continued the family business.Now on death of one of them does his legal heirs have right in the business.The partnership deed is silent about the rights to legal heirs.Also does the legal heir of that deceased partner have any rights on the property of the business.
