Introduction<\/strong><\/p>\n<p>This article examines the meaning of \u201cauthor\u2019s supervision\u201d as invoked in practice during alterations, and the extent to which the original architect may influence subsequent modifications. The issue is not merely theoretical: in planning and development processes, developers regularly encounter the question of whether author\u2019s supervision entails a right of approval or constitutes a different and more limited role within the copyright regime governing architectural works.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>2. Author\u2019s supervision within the framework of the Hungarian Copyright Act<\/strong><\/p>\n<p>Hungary\u2019s Act LXXVI of 1999 on Copyright (hereinafter: the \u201cCopyright Act\u201d) does not define the concept of \u201cauthor\u2019s supervision\u201d, nor does it recognise it as an independent copyright or a distinct entitlement. With regard to architectural works, the Copyright Act regulates the following relevant rights:<\/p>\n<ol>\n<li>the right to authorise use (Sections 16 and 29);<\/li>\n<li>the right to the integrity of the work (Section 13); and<\/li>\n<li>the prohibition of unauthorised alteration of architectural works (Section 67).<\/li>\n<\/ol>\n<p>Although these rights afford significant protection to the author, they do not give rise to a continuous right of control or approval in the course of the design process of an alteration. The relevant provisions of the Copyright Act define the author\u2019s rights to authorise uses of the work and provide for enforcement and remedies in cases of infringement. Consequently, there is nothing in the Copyright Act to suggest that a designer has any right that would amount to a \u201cpermanent control mechanism\u201d.<\/p>\n<p>Within the framework of the Hungarian Copyright Act, the exercise of copyright in architectural works necessarily coexists with the property rights held by the owner of the relevant building. Judicial practice has consistently held that the owner of a building has the right to carry out reconstruction, alteration and modernisation projects, and that the architect\u2019s copyright cannot place unlimited restrictions on such right. Ownership rights collide with copyright limitations only where the planned modifications affect the essential characteristics of the work or endanger the author\u2019s honour or reputation. For a detailed discussion of the considerations for balancing ownership rights and copyrights, please see <a href=\"https:\/\/constructionpapers.hu\/en\/construction\/when-is-the-designers-approval-needed-for-alterations\/\">\u00a0a previous article on this matter.<\/a><\/p>\n<p>Both the Budapest Court of Appeal and the Curia, Hungary\u2019s highest court, have consistently ruled that interventions connected to the proper use, modernisation, or change of function of a building do not in themselves grant a right of prohibition to the original designer, nor do they create a \u201csupervisory\u201d right that can place general restrictions on the exercise of ownership rights (see e.g. 9.Pf.20.125\/2024\/7-II.; Gf.I.30.275\/2015\/10.).<\/p>\n<p>&nbsp;<\/p>\n<p><strong>3. The proper interpretation of Section 18 (6) of the Code of Ethics and Disciplinary Rules of the Chamber of Hungarian Architects<\/strong><\/p>\n<p>Section 18 (6) of the Code of Ethics and Disciplinary Rules of the Chamber of Hungarian Architects (the \u201cCode\u201d) states that \u201cif the plans for the reconstruction, alteration, extension or modernisation of a completed building are not prepared by the original designer, the intervening designer shall, at the request of the original designer, ensure that author\u2019s supervision is provided.\u201d The interpretation of this rule is of particular practical importance, as the majority of disputes concerning the meaning and legal nature of \u201cauthor\u2019s supervision\u201d are connected to it.<\/p>\n<p>Section 18 (6) of the Code expressly makes the obligation to ensure author\u2019s supervision conditional upon the \u201crequest of the original designer\u201d. This wording clearly presupposes a right vested in a specific individual and requires an active and express assertion by the original designer. Both grammatically and systematically, the notion of a \u201crequest\u201d implies a living and legally capable author who is able to exercise this right. In the absence of such a person (for example, in the event of the original designer\u2019s death), the prerequisite set out in the rule cannot be fulfilled; consequently, the rule in that case is ab ovo inapplicable.<\/p>\n<p>In the general meaning of the Code, the \u201cprovision of author\u2019s supervision\u201d denotes a professional activity rather than an independent legal entitlement. Its substance lies not in a legal act but in the professional monitoring of the design process and the opportunity to formulate observations. Neither a grammatical nor a systematic interpretation of the Code supports the conclusion that author\u2019s supervision entails a right of approval or prohibition, or the power to halt an investment project. Ensuring supervision constitutes an opportunity for professional participation, not a decision-making power.<\/p>\n<p>It should be emphasised that the holders of moral rights under the Hungarian Copyright Act cannot be equated with the concept of the \u201coriginal designer\u201d for the purposes of applying Section 18 (6) of the Code. Such right holders do not possess creative status, did not participate in the preparation of the original design, and do not perform a professional design function in relation to the specific work. Accordingly, the exercise of moral rights does not necessarily entail the possibility of performing author\u2019s supervision. Section 18 (6) designates a personal, professional form of participation vested exclusively in the original designer. Legal succession in copyright does not create a new authorship status, nor does it transfer the original designer\u2019s professional standing; it extends solely to the exercise of the moral rights specified by law.<\/p>\n<p>Furthermore, the wording \u201censure\u201d used in Section 18 (6) does not, under either grammatical or systematic interpretation, support the view that the intervening designer has an obligation to make decisions or grant approvals. The term \u201censure\u201d refers to the possibility of exercising supervisory activity, not to guaranteeing any particular outcome, and cannot be transformed into a binding control mechanism.<\/p>\n<p><strong>In the light of the above, it appears reasonable to argue that neither the Hungarian Copyright Act nor Section 18 (6) of the Code creates an independent copyright entitlement, grants a right of approval or veto, or extends to the holders of moral rights. The exercise of author\u2019s supervision therefore cannot be interpreted as a right of approval or veto over design decisions, as the Code provides exclusively for a form of professional participation in this respect.<\/strong><\/p>\n<p>This does not, of course, preclude the parties from agreeing, within the framework of contractual freedom under civil law, on the terms of the original designer\u2019s (or even his or her successors\u2019) involvement, the manner in which author\u2019s supervision is to be exercised, or even approval mechanisms. However, such an agreement will not constitute generally applicable rights arising from a statute but contractual positions under the law of obligations, deriving from the specific agreement of the parties and to be assessed in light of all the circumstances of the individual case.<\/p>\n<p style=\"text-align: center;\">***<\/p>\n<p><em>Author: Zsanett Szab\u00f3 <\/em><br \/>\n<em>Bal\u00e1zs Bagi, a law student, contributed to this article.<\/em><\/p>\n<p><img decoding=\"async\" class=\"alignnone size-medium wp-image-31896 lazyload\" data-src=\"https:\/\/constructionpapers.hu\/wp-content\/uploads\/2026\/02\/Dr.-Szabo-Zsanett_szines-219x300.jpg\" alt=\"\" width=\"219\" height=\"300\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 219px; --smush-placeholder-aspect-ratio: 219\/300;\" \/><\/p>\n<p style=\"text-align: center;\">If you are interested in more articles on construction law, please visit our website: <a href=\"https:\/\/constructionpapers.hu\/en\/\"><strong>Construction Papers<\/strong><\/a><\/p>\n<p style=\"text-align: center;\">Copyright \u00a9 2026 CERHA HEMPEL Dezs\u0151 and Partners \u2013 all rights reserved.<\/p>\n<p style=\"text-align: center;\"><strong>Mailing address:<\/strong><br \/>\nCERHA HEMPEL Dezs\u0151 \u00e9s T\u00e1rsai \u00dcgyv\u00e9di Iroda<br \/>\n1011 Budapest<br \/>\nF\u0151 utca 14-18.<br \/>\nMagyarorsz\u00e1g<\/p>\n<p style=\"text-align: center;\"><strong>E-mail:<\/strong><br \/>\n<a href=\"mailto:zsanett.szabo@cerhahempel.hu\">zsanett.szabo@cerhahempel.hu<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This article examines the meaning of \u201cauthor\u2019s supervision\u201d as invoked in practice during alterations, and the extent to which the original architect may influence subsequent modifications.<\/p>\n","protected":false},"author":7,"featured_media":31950,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"categories":[270,282,274],"tags":[],"class_list":["post-31955","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-construction","category-epitkezes","category-epitoipar-en"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Alterations and Author\u2019s Supervision Defining the Scope of the Original Architect\u2019s Authority - CONSTRUCTION PAPERS<\/title>\n<meta name=\"description\" content=\"The article examines the meaning of \u201cauthor\u2019s supervision\u201d during alterations, and the extent to which the original architect may influence modifications.\" \/>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/constructionpapers.hu\/en\/construction\/alterations-and-authors-supervision-the-scope-of-the-original-architects-authority\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Alterations and Author\u2019s Supervision Defining the Scope of the Original Architect\u2019s Authority - CONSTRUCTION PAPERS\" \/>\n<meta property=\"og:description\" content=\"The article examines the meaning of \u201cauthor\u2019s supervision\u201d during alterations, and the extent to which the original architect may influence modifications.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/constructionpapers.hu\/en\/construction\/alterations-and-authors-supervision-the-scope-of-the-original-architects-authority\/\" \/>\n<meta property=\"og:site_name\" content=\"CONSTRUCTION PAPERS\" \/>\n<meta property=\"article:published_time\" content=\"2026-03-17T13:15:36+00:00\" \/>\n<meta property=\"og:image\" content=\"https:\/\/constructionpapers.hu\/wp-content\/uploads\/2026\/03\/Boritokep_Szerzoi-felugyelet_v4-scaled.jpg\" \/>\n\t<meta property=\"og:image:width\" content=\"2560\" \/>\n\t<meta property=\"og:image:height\" content=\"1322\" \/>\n\t<meta property=\"og:image:type\" content=\"image\/jpeg\" \/>\n<meta name=\"author\" content=\"andras.fenyohazi\" \/>\n<meta name=\"twitter:label1\" content=\"Written by\" \/>\n\t<meta name=\"twitter:data1\" content=\"dr.
