This is a practically important question for legal heirs in Mumbai managing inherited property, and the legal position requires understanding the distinction between what a succession certificate actually establishes and what it does not. Technically, a legal heir can enter into a sale transaction for inherited property even before formally obtaining a succession certificate, since the heir's rights to the property generally arise automatically upon the deceased's death under applicable succession law, not from the succession certificate itself — the certificate primarily serves to establish, for evidentiary and administrative purposes, who the rightful heirs are, particularly for debts, securities, and certain financial assets.

However, proceeding with a sale before obtaining a succession certificate, particularly where there are multiple potential heirs or any uncertainty about who the rightful heirs are, carries significant practical risk, since buyers, banks, and registration authorities in Mumbai typically require documentary proof of clear succession before completing a property transaction involving inherited assets. Without a succession certificate or equivalent documentation such as a legal heir certificate, letters of administration, or probate of a Will, a prospective buyer faces genuine uncertainty about whether the seller actually has full and exclusive authority to sell, making many buyers understandably reluctant to proceed, or requiring the seller to obtain proper succession documentation before the sale can be registered.

Where a property is being sold on the strength of a Will rather than intestate succession, probate of that Will is compulsory in certain circumstances under the Indian Succession Act, 1925, particularly for Wills executed by Hindus, Buddhists, Sikhs, or Jains within the territories that were formerly part of the Bengal, Madras, and Bombay Presidencies — which notably includes Mumbai — meaning probate is generally a mandatory prerequisite before a sale based on that Will can proceed with proper legal certainty, not merely an optional formality.

Where multiple legal heirs exist and only one attempts to sell without securing either a succession certificate reflecting all heirs' shares or explicit consent and participation from the other heirs, this exposes the sale to the same vulnerabilities discussed regarding unauthorized sales by a single heir — the other heirs retain the right to challenge the transaction to the extent it exceeds the selling heir's actual entitled share, regardless of whether a succession certificate was technically obtained or not, since the certificate itself doesn't create rights but merely evidences them.

Given how proceeding without proper succession documentation exposes both sellers and buyers to significant legal risk, obtaining appropriate succession certificates, letters of administration, or probate before completing any inherited property sale in Mumbai is strongly advisable, even where not strictly legally mandatory in every case.
