Under the Real Estate (Regulation and Development) Act, 2016 (RERA for short), it is compulsory for all builders to obtain approvals from government agencies before the housing project is thrown open to the public. All relevant information must be made available on the state RERA authority website.
In this case, or for that matter in any default case, the buyer can file an online complaint against the builder/promoter on the respective state portal of RERA. Details about the builder/promoter and payment along with the type of relief sought must also be mentioned for clarity. A practising RERA advocate should be consulted to get the right and effective legal opinion.
