Yes, general permission is available to the NRls/PIO to repatriate the sale proceeds of the immovable property inherited from a person resident in India.
NRls/PIO may repatriate an amount not exceeding USD one million, per financial year, on production of documentary evidence in support of acquisition / inheritance of assets, an undertaking by the remitter and certificate by a Chartered Accountant in the formats prescribed by the Central Board of Direct Taxes vide their Circular No. 10/2002 dated October 9,2002. [cf. A P. (DIR Series) Circular No.56 dated November 26, 2002].
In case of a foreign national, sale proceeds can also be repatriated even if the property is inherited from a person resident outside India. But this is allowed only with prior approval of Reserve Bank.
The foreign national has to approach Reserve Bank with documentary evidence in support of inheritance of the immovable property and the undertaking and the CA Certificate as mentioned above. The general permission for repatriation of sale proceeds of immovable property is not available to a citizen of Pakistan, Bangladesh, Sri Lanka, China, Afghanistan and Iran and he has to seek specific approval of Reserve Bank.
As FEMA specifically permits transactions only in Indian Rupees with citizens of Nepal and Bhutan, the question of repatriation of the sale proceeds in foreign exchange to Nepal and Bhutan would not arise.
