Say if money transferred as "maintenance" is used in some investment, like buying a house or investing in stocks or bonds abroad, is there any rule against it? It is to be noted here that once the money is transferred to NRI account abroad, there is no control of resident Indian father, wheather under the option of "maintenance" or under the option of "gift" and therefore, common sense says, that issue is irrelevant from taxation point of view for any party. Please clarify.
