A missing addendum, an oral side agreement, an extension with a handshake \u2013 and a lease agreement concluded for ten years was suddenly terminable at any time. Livelihoods depended on whether a piece of paper had been correctly signed.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Since 1 January 2025, this has been different. The Fourth Bureaucracy Relief Act (BEG IV) amended Section 550 of the German Civil Code (BGB) and replaced the written form requirement in commercial tenancy law with the <\/span><b>Text form<\/b><span style=\"font-weight: 400;\"> replaced. But what does that mean for you specifically? And what applies to contracts concluded before 2025?<\/span><\/p>\n<p><b>Note:<\/b><span style=\"font-weight: 400;\"> This post is for general guidance only and does not replace individual legal advice. Particularly with commercial lease agreements for long terms and high economic values, formal requirements should always be checked by a solicitor.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Die_alte_Rechtslage_Warum_die_Schriftform_so_gefahrlich_war\"><\/span><b>The old legal situation: Why the written form was so dangerous<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Until the end of 2024, for commercial lease agreements with a term of more than one year, the following applied: no written form, no protection of tenancy. Section 550 of the German Civil Code (BGB) in its former version stated, in essence: If a lease agreement for a period longer than one year is not concluded in writing, it shall be deemed to be for an indefinite period.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The consequence was serious. A contract that was originally supposed to run for a fixed term of ten years could be terminated by either party with the statutory notice period of six months at the end of a quarter (\u00a7 580a para. 2 BGB) \u2013 if there was any defect in the written form.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">And such deficiencies were found almost everywhere.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Because the written form under Section 126 of the German Civil Code (BGB) is strict:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Both parties must <\/span><b>handwritten on the same document<\/b><span style=\"font-weight: 400;\"> sign<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">All essential contract contents must be included in the deed itself \u2013 parties, rental property, rent amount, term, purpose of use.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Addenda and amendments must also be in writing \u2013 either by being permanently attached to the original or by a separate, complete document with a reference to it.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Verbal side agreements \u2014 even if both parties confirm them \u2014 did not observe the written form.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">In practice, this led to absurd situations. Landlords and tenants were in complete agreement about a contract extension or a rent adjustment \u2013 but because the agreement was only reached by email, handshake, or conduct, the entire contract suddenly became terminable. And not infrequently, one side deliberately exploited exactly this formal defect to free themselves from a contract that had become undesirable.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Ein_Fall_aus_der_Praxis_OLG_Munchen_07042016_23_U_316215\"><\/span><b>A case from practice: Higher Regional Court of Munich, 07.04.2016 (23 U 3162\/15)<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">A case decided by the Higher Regional Court of Munich in 2016 shows how dangerous the old legal situation was.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Der_Sachverhalt\"><\/span><b>The facts of the case<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">A commercial tenant rented a retail space with storage and parking spaces in November 2013. The written lease agreement was for an indefinite period with a short <a href=\"https:\/\/www.mth-partner.de\/en\/receive-your-72-hour-emergency-plan\/\">Cancellation period<\/a> for three months. In February 2014, a supplementary agreement for advertising space was added.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The tenant claimed that the landlady had verbally promised him a waiver of notice for 25 years \u2013 or at least for five years. Without this promise, he would not have made the significant investments in the property. The landlady denied this. In July 2014, she terminated the contract with appropriate notice.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Die_Entscheidung\"><\/span><b>The decision<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The Higher Regional Court of Munich ruled in favour of the landlady. The tenant could not prove the alleged waiver of notice. However, even if he had been able to, according to the court, the oral waiver would have been invalid under \u00a7\u00a7 550, 126 of the German Civil Code (BGB). <\/span><b>Ineffective<\/b><span style=\"font-weight: 400;\"> been - as a multi-year period of exclusion of termination is an essential term of the contract that would have required written form.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Even a so-called double written form clause in the contract \u2013 meaning a clause stipulating that amendments are only valid in writing \u2013 did not help the tenant. The court clarified: the statutory written form requirement cannot be circumvented by contractual clauses. The termination was effective as of 31 March 2015 (\u00a7 580a para. 2 BGB).<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Die_Lehre_aus_diesem_Fall\"><\/span><b>The lesson from this case<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">What does this case show? Under the old legal situation, a commercial tenant who relied on verbal assurances and invested everything lost out \u2013 because the assurance was not put down in writing. The landlord could terminate the contract at any time, and the tenant was left without legal protection.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Die_neue_Rechtslage_seit_2025_Textform_statt_Schriftform\"><\/span><b>The New Legal Situation Since 2025: Text Form Instead of Written Form<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The Fourth Bureaucracy Relief Act (BEG IV) amended Section 550 of the German Civil Code (BGB) on 1 January 2025. For commercial leases, it has since been sufficient for <\/span><b>Text form<\/b><span style=\"font-weight: 400;\"> pursuant to \u00a7 126b BGB.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Was_ist_Textform\"><\/span><b>What is text format?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Text form means: a readable explanation, in which the person giving the explanation is named, submitted on a durable data carrier. Specifically, this can be:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">An email<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A PDF document<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A fax<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A messenger message (theoretically - not recommended in practice)<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Of course, a signed paper document as well<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Was <\/span><b>not<\/b><span style=\"font-weight: 400;\"> suffices: a purely oral agreement, a phone call or a handshake. Even under the new legal situation, something written (or electronically readable) must be provided.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Ubergangsfristen_Was_gilt_fur_Altvertrage\"><\/span><b>Transition periods: What applies to existing contracts?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<table>\n<tbody>\n<tr>\n<td><b>Period<\/b><\/td>\n<td><b>What applies<\/b><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">New contracts from 01\/01\/2025<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Agreements by email are effectively allowed to be entered into for a limited period.<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Addendums to Existing Contracts from 01.01.2025<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Text is sufficient for the addendum<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Old contracts (concluded before 2025) until 31.12.2025<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Old form of writing still valid \u2014 termination due to formal defect still possible<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>Old contracts from 01\/01\/2026<\/b><\/td>\n<td><b>The text form also suffices for old contracts<\/b><span style=\"font-weight: 400;\"> Termination due to lack of written form ceases to apply if the text form is observed<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><span style=\"font-weight: 400;\">This is the crucial point. From 1 January 2026, landlords and tenants will no longer be able to terminate a commercial lease agreement on the grounds that an old addendum was not personally signed by hand, provided that the addendum exists in text form at least.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Was_bedeutet_das_fur_den_OLG-Munchen-Fall\"><\/span><b>What does this mean for the OLG Munich case?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Under the new legal situation, the case could have had a different outcome. If the tenant had confirmed the verbal waiver of termination by email, or even just recorded it in a written summary of the conversation, the written form would have been observed. The waiver would have been effective, and the landlady could not have terminated the tenancy.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, even under the new legal situation, a purely verbal waiver would not have been sufficient. Written form is not the same as freedom of form. Anyone who wants to be on the safe side must write it down \u2013 whether on paper or by email.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Praktische_Konsequenzen_fur_Gewerbemieter_und_Vermieter\"><\/span><b>Practical consequences for commercial tenants and landlords<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Fur_Mieter\"><\/span><b>For tenants<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">For you as a commercial tenant, the relief provided by the written form is real \u2013 but not a free pass for negligence.
