Flat buyers in Mumbai frequently ask whether they can pursue both a RERA complaint and a civil suit against the same builder for related grievances, and the legal position here requires careful navigation since it involves questions of jurisdiction, overlapping remedies, and potential procedural bars that can affect your overall strategy. Generally, RERA proceedings and civil suits can run simultaneously in certain circumstances, but there are important limitations, particularly regarding matters that squarely fall within RERA's specific jurisdiction under the Real Estate (Regulation and Development) Act, 2016.

Section 79 of the RERA Act specifically bars civil courts from entertaining any suit or proceeding in respect of matters which the RERA Authority or the Real Estate Appellate Tribunal is empowered to determine, meaning for core RERA matters — such as claims for possession delay, refund with interest under Section 18, or structural defect liability under Section 14(3) — the civil court's jurisdiction is expressly ousted, and these grievances must be pursued exclusively before the RERA Authority rather than through a parallel civil suit. This bar exists precisely because RERA was created as a specialised, faster forum for exactly these categories of disputes, and Parliament intended to channel such claims away from the traditionally slower civil court system.

However, this jurisdictional bar under Section 79 does not extend to every possible dispute between a buyer and builder — matters involving fraud, criminal misrepresentation, disputes over specific performance of an agreement to sell where possession delivery isn't the core issue, or claims that genuinely fall outside RERA's defined scope can still be pursued before civil courts even while a related RERA complaint is pending on the specific RERA-covered issues. The key distinguishing factor courts examine is whether the civil suit seeks relief that RERA itself is empowered to grant, or whether it addresses a genuinely separate legal question RERA cannot resolve.

Where a buyer has multiple grievances against the same builder spanning both RERA-specific issues and matters outside RERA's jurisdiction, a carefully structured dual approach — pursuing the RERA complaint for statutory remedies like refund and compensation, while separately pursuing civil remedies for matters like fraud or specific performance that fall outside RERA's scope — can be strategically effective, though this requires careful legal drafting to avoid the risk of either proceeding being challenged as an improper attempt to relitigate the same issue in two forums.

Given how nuanced this jurisdictional overlap can be, and how a poorly structured approach risks having one or both proceedings dismissed on jurisdictional grounds, professional legal strategy is essential before pursuing parallel proceedings.
