S.213 of Indian Succession Act, 1925 provides :
SECTION 213 : Right as executor or legatee when established
(1) No right as executor or legatee can be established in any Court of Justice, unless a Court of competent jurisdiction in India has granted probate of the will under which the right is claimed, or has granted letters of administration with the will or with a copy of an authenticated copy of the will annexed.
(2) This section shall not apply in the case of wills made by Muhammadans ["or Indian Christians"] and shall only apply-
(i) in the case of wills made by any Hindu, Buddhist, Sikh or Jaina where such wills are of the. classes specified in clauses (a) and (b) of section 57; and
(ii) in the case of wills made by any Parsi dying, after the commencement of the Indian Succession (Amendment) Act, 1962, where such wills are made within the local limits of the ordinary original civil jurisdiction of the High Courts at Calcutta, Madras and Bombay, and where such wills are made outside those limits, in so far as they relate to immovable property situate within those limits.
SECTION 57 : Application of certain provisions of Part to a class of wills made by Hindus, etc
The provisions of this Part which are set out in Schedule III shall, subject to the restrictions and modifications specified therein, apply-
(a) to all wills and codicils made by any Hindu, Buddhist, Sikh or Jaina, on or after the first day of September, 1870, within the territories which at the said date were subject to the Lieutenant-Governor of Bengal or within the local limits of the ordinary original civil jurisdiction of the High Courts of Judicature at Madras and Bombay; and
(b) to all such wills and codicils made outside those territories and limits so far as relates to immovable property situate within those territories or limits; and
(c) to all wills and codicils made by any Hindu, Buddhist, Sikh or Jaina on or after the first day of January, 1927, to which those provisions are not applied by clauses (a) and (b):
The Apex Court in the case of Clarence Pais and Ors. V/s. Union of India, AIR 2001 SC 1151 wherein while considering the constitutional validity of the provisions of Sec. 213 vis-a-vis Sec. 57 of the Indian Succession Act at para 6, it has been observed by the Apex Court inter alia as under:
"A combined reading of Sec. 213 and 57 of the Act would show that where the parties to the will are Hindus or the properties in dispute are not in territories falling u/s. 57(a) and (b), sub-sec. (2) of Sec. 213 of the Act applies and sub-sec. (1) has no application. As a consequence, a probate will not be required to be obtained by a Hindu in respect of a will made outside those territories or regarding the immovable properties situate outside those territories."
Gujarat High Court has held as under in the matter of Minaxiben Shashikantbhai Patel Versus District Collector, Gandhinagar (2007 (1) GLR 277 : 2007 (1) GCD 392):
"Succession Act, 1925 - S. 57, 213 - whether for Will executed by Hindu qua property situated outside original civil jurisdiction of High Court at Calcutta, Madras and Mumbai, probate is compulsory requirement for establishing rights pursuant to Will - property situated at Gandhinagar - whether probate for such Will is necessary requirement for claiming any right under said Will - held, probate, will not be required for establishing rights acquired by executor or legatee of Will before Court or before any other authority - impugned communication quashed and set aside - petition allowed."
Also definition of Legal representative is also provided in S.2(11) of CPC. Further Order 22, Rule 3 provides substitution of plaintiff wherein it has been held that a universal legatee can institute a suit on primafacie proof of will (AIR 1982 PAT. 208) and a LR may or may not be heir but should represent the estate even without tile as an executor or administrator (AIR 1989 SC 1589)
Therefore if a Hindu Will is execute outside of the territory mentioned in S.57 then probate is not necessary and also to continue a suit probate is not necessary.
