The effective date of a CA partnership deed is generally the date of registration of the partnership firm with the ICAI if it is a new firm with a new name. If the partnership is formed with a new name, the effective date of partnership will be the date of registration of the new partnership firm with ICAI. If it is a merger or conversion of an existing proprietorship firm into a partnership, the effective date depends on the registration date or the date when the partner formally joins the firm.

Regarding the use of an old Firm Registration Number (FRN) until a new FRN is allotted by ICAI, if a new partnership firm with a new name is constituted, a new FRN will be allotted. In case of conversion from proprietorship to partnership, the existing FRN can continue. The FRN which continues or is specified in merger/demerger cases must be indicated in filings to ICAI. However, one cannot continue to use the old FRN indefinitely if a new entity is created that demands a new registration.
