How to Do Company Succession in Germany: Step‑by‑step Guide for Cross‑border Transfers

Company succession in Germany, known as Unternehmensnachfolge, is the legal and commercial process through which ownership of a business transfers to a new owner, whether by share sale, asset deal, or inheritance. Understanding how to do company succession in Germany is critical for any cross‑border buyer, foreign investor, or family‑business owner planning a transfer, because the process intersects corporate law (GmbHG, AktG), employee‑protection rules (BGB §613a), inheritance and gift tax (ErbStG), and, increasingly in 2026, foreign‑direct‑investment screening under the AWV/AWG and merger control before the Bundeskartellamt. This guide sets out every procedural stage, the documents you will need, realistic timelines and cost ranges, and the regulatory sequencing changes that now shape deal timetables.

Overview of the Unternehmensnachfolge Process and Who It Applies To

Unternehmensnachfolge covers any transfer of a going concern, whether through a sale of Geschäftsanteile (shares in a GmbH), a listed‑company stock acquisition under the AktG, an asset deal, or a succession triggered by death or retirement. The process applies to owner‑managed Mittelstand businesses, family‑held groups and portfolio companies alike.

Cross‑border issues arise whenever the buyer is domiciled outside Germany, the seller is a non‑resident, or the target is part of a multinational group. In each case the transaction must satisfy German corporate formalities, including mandatory notarisation for GmbH share transfers, and comply with employment, tax, and regulatory frameworks that do not apply to purely domestic deals of the same size.

The legal framework governing this process is spread across several statutes. The GmbHG sets out the rules for transferring GmbH shares, including notarisation requirements. BGB §613a protects employees when a business or part of a business is transferred to a new owner. The Erbschaftsteuer‑ und Schenkungsteuergesetz (ErbStG) determines inheritance and gift tax and provides business‑succession reliefs. The Außenwirtschaftsverordnung (AWV), together with the Außenwirtschaftsgesetz (AWG), governs FDI screening by the Federal Ministry for Economic Affairs and Climate Action (BMWK). Finally, the Gesetz gegen Wettbewerbsbeschränkungen (GWB) empowers the Bundeskartellamt to review concentrations that meet German merger‑control thresholds.

Eligibility and Prerequisites for Company Succession in Germany

Before any transaction documents are drafted, both buyer and seller must confirm that they satisfy the corporate, employment and regulatory prerequisites described below.

Corporate Prerequisites, GmbH vs AG

For a GmbH, the articles of association (Gesellschaftsvertrag) must be reviewed for transfer restrictions, pre‑emptive rights (Vorkaufsrechte), consent requirements and tag‑along or drag‑along clauses. A transfer of GmbH shares requires notarisation of the share‑transfer agreement under the GmbHG; without notarisation, the transfer is void. Shareholders must pass any required resolutions, and the new shareholder list must be filed with the commercial register (Handelsregister).

For an AG (public limited company), shares are typically freely transferable unless the articles impose restrictions (vinkulierte Namensaktien). Board approvals, and, in some cases, supervisory‑board consent, may still be needed.

Employment and Works‑Council Triggers

Where a business or an identifiable part of a business transfers, BGB §613a mandates automatic transfer of all affected employment relationships to the new owner. The employer must inform employees in writing of the transfer, its reasons, and the legal, economic and social consequences. Where a works council (Betriebsrat) exists, it must be consulted under the Betriebsverfassungsgesetz before the transaction closes.

Regulatory Triggers, Bundeskartellamt and FDI Screening

Merger control applies when the parties’ combined worldwide turnover and German turnover exceed the thresholds set by the GWB. The Bundeskartellamt must be notified before closing. Under the AWV, the BMWK screens acquisitions of German companies by non‑EU/EFTA buyers in sensitive sectors, including critical infrastructure, defence, IT security and key technologies. Industry observers expect that in 2026 these reviews are taking longer and covering a wider range of sectors, making early regulatory scoping essential for cross‑border succession deals.

Step‑by‑Step Procedure: How to Do Company Succession in Germany

The Unternehmensnachfolge process can be broken into eight sequenced stages. At a high level, five core steps define the succession: (1) scope the deal structure and valuation; (2) assess regulatory requirements; (3) engage employees and the works council; (4) negotiate, execute and notarise the transaction; and (5) close and integrate. The detailed breakdown below expands each of those stages into actionable tasks with responsible parties and durations.

Step 1, Early Scoping and Options Analysis

Who acts: seller, M&A counsel, tax adviser.

The first stage determines whether the succession will proceed as a share deal or an asset deal, and sets the valuation framework. Key tasks include:

• Review the articles of association for transfer restrictions, pre‑emptive rights and consent clauses under the GmbHG.
• Conduct a preliminary tax analysis, assess eligibility for ErbStG business‑succession reliefs (§§13a, 13b ErbStG) and compare the tax profiles of share vs asset structures for both seller and buyer.
• Obtain or commission a company valuation, income, asset‑based or market‑comparison methods. The valuation underpins the purchase price and any tax filing.
• Identify key dependencies, change‑of‑control clauses in customer/supplier contracts, licence agreements, loan covenants.

Duration: 2–6 weeks. Do not progress to a binding term sheet until scoping is complete.

Step 2, Regulatory Scoping (FDI and Merger Control)

Who acts: external competition / FDI counsel.

This step determines whether the transaction requires notification to the Bundeskartellamt (merger control) or the BMWK (FDI screening under the AWV/AWG). Key actions:

• Run the merger‑control checklist, compare combined worldwide and German turnover against the statutory thresholds published by the Bundeskartellamt. If thresholds are met, notification is mandatory before closing.
• Run the FDI checklist, determine whether the target operates in a sector covered by the AWV sector lists (critical infrastructure, cloud computing, telecom, media, defence, key technologies). If so, the BMWK may review and must clear the acquisition.
• Consider pre‑notification, where filings are likely, begin informal pre‑notification discussions with the relevant authority to shorten formal review times.

Duration: 1–4 weeks for scoping. Formal filing and review windows add 4–24+ weeks, depending on complexity and the authority’s caseload. In 2026, early indications suggest both the Bundeskartellamt and the BMWK are operating with extended review periods, build contingency into your timetable.

Step 3, Employee and Works‑Council Engagement

Who acts: management, HR department, labour counsel.

Under BGB §613a, the transferor and the transferee must inform affected employees in writing about the planned transfer, its date, the reason for the transfer, and the legal, economic and social consequences for employees. Employees have the right to object to the transfer of their employment within one month of being properly informed.

Where a works council exists, the employer must consult it under the Betriebsverfassungsgesetz. The works council has a right to be informed about the reasons for the transfer, the consequences for employees, and any measures envisaged. This consultation should run concurrently with deal negotiation but must be coordinated with confidentiality obligations, prepare a communication protocol that aligns the works‑council briefing with the SPA timetable.

Duration: 2–6 weeks, running concurrently with Steps 2 and 4. Poor timing of works‑council engagement is one of the most common pitfalls in German succession steps.

Step 4, Draft and Sign Term Sheet or Letter of Intent

Who acts: buyer and seller deal teams, M&A counsel.

The LOI or term sheet should set out the key commercial terms: purchase price (or formula), deal structure, exclusivity period, and, critically, conditionality for regulatory clearances. In a cross‑border succession, include:

• A regulatory‑clearance condition precedent (merger control and/or FDI).
• A longstop date tied to the expected clearance window, with an extension mechanism.
• Break‑fee provisions if clearance is not obtained.

Duration: 1–3 weeks.

Step 5, Due Diligence and Negotiation of the SPA or APA

Who acts: buyer counsel (leading), seller counsel (responding), financial and tax advisers.

Due diligence covers legal, financial, tax, employment, environmental and commercial workstreams. For a company succession in Germany, pay particular attention to:

• Employee data and pension liabilities, needed for §613a compliance and purchase‑price adjustments.
• Tax liabilities and open assessments, confirm whether ErbStG reliefs were previously claimed and check holdover conditions.
• Change‑of‑control clauses, in material contracts, licences and financing agreements.
• Environmental and compliance records, particularly for manufacturing or regulated industries.

Negotiate the share purchase agreement (SPA) or asset purchase agreement (APA) in parallel with due diligence findings. Key clauses: representations and warranties, indemnities, purchase‑price adjustments, non‑compete, and escrow or retention mechanisms.

Duration: 3–8 weeks.

Step 6, Contract Execution and Notarisation

Who acts: German notary, parties’ counsel.

For a GmbH share transfer, the share‑transfer agreement must be notarised by a German notary under the GmbHG. Without notarisation, the transfer is legally void. The notary will also prepare the updated shareholder list and file it with the Handelsregister. If a party signs through a representative, the power of attorney must itself be notarised.

For an asset deal or an AG share transfer, notarisation may not be required for the transfer itself, but individual assets (such as real estate) may trigger separate notarisation and registration obligations.

Duration: 1–6 weeks (including scheduling, notarisation appointment and register filing).

Step 7, Regulatory Filings and Clearance Monitoring

Who acts: counsel (leading), buyer.

If merger control applies, file the notification with the Bundeskartellamt. The authority has one month for a Phase I review; if it opens a Phase II investigation, the review may extend significantly. Do not close before clearance is obtained, a completed but un‑notified merger is subject to sanctions and may be unwound.

If FDI screening applies, the BMWK reviews the acquisition under the AWV. Clearance periods under the FDI regime can extend well beyond the initial statutory windows where the authority requests additional information or initiates an in‑depth review. The likely practical effect of the 2026 regulatory environment is that review windows are longer than historical averages, see the dedicated section below.

Duration: 4–24+ weeks. Build this window into the longstop date in the SPA.

Step 8, Closing and Post‑Closing Tasks

Who acts: management, HR, tax advisers.

Once all conditions precedent are satisfied (regulatory clearances, shareholder approvals, works‑council process complete), proceed to closing. Post‑closing tasks include:

• Final Handelsregister updates (new managing directors, updated shareholder list).
• Formal employee notifications under BGB §613a (if not completed pre‑closing).
• Tax filings, inheritance/gift tax returns, real‑estate transfer tax, VAT adjustments.
• Integration milestones, IT, banking, contract novations, public announcements via the Bundesanzeiger where applicable.

Duration: 1–8 weeks.

Required Documents for Company Succession in Germany

The documents needed for a German Unternehmensnachfolge depend on the deal structure, but the following table covers the standard requirements for a typical share‑ or asset‑based transfer. Assemble these early to avoid delays at notarisation or during due diligence.

Timeline and Key Deadlines for the Unternehmensnachfolge Process

Timelines vary significantly depending on deal size, regulatory exposure and the complexity of the target business. The table below illustrates two reference scenarios: a straightforward domestic GmbH sale and a mid‑market cross‑border transfer that triggers FDI and merger‑control reviews.

For a simple GmbH sale with no regulatory filings, the entire process, from initial scoping to Handelsregister update, can be completed in 3–5 months. A mid‑market cross‑border transaction that triggers FDI screening and merger control should allow 6–12 months, and in some cases longer if an in‑depth FDI review is initiated. Works‑council consultation timelines overlap with deal negotiation and should be planned as concurrent work streams, not sequential ones.

Statutory deadlines to track include: the one‑month employee objection period after proper §613a notification; the Bundeskartellamt’s one‑month Phase I review period (extendable to Phase II); and any holdover periods attached to ErbStG business‑succession tax reliefs.

Costs, Fees and Tax Considerations for Company Succession in Germany

The table below sets out indicative cost ranges for a typical mid‑market succession. All figures are estimates, verify with your counsel and notary before budgeting.

On the tax side, the ErbStG provides business‑succession reliefs under §§13a and 13b that can substantially reduce the inheritance or gift tax burden on a qualifying transfer. These reliefs are subject to strict conditions, including minimum holdover periods during which the business must continue to operate and maintain a minimum payroll level. Failure to meet holdover conditions triggers a clawback of the relief. Given the complexity and the financial stakes, specialist tax advice should be obtained at the earliest scoping stage, well before the SPA is signed.

What Changes in 2026: Regulatory Sequencing for Company Succession in Germany

The 2026 regulatory environment in Germany and the EU has become markedly more interventionist. Industry observers expect two developments to reshape the succession steps Germany practitioners must follow:

• Longer FDI review windows. The BMWK is applying wider screening criteria under the AWV, particularly for targets in critical technology, data infrastructure, cloud services and defence supply chains. Early indications suggest formal review timelines are extending beyond historical norms. The practical consequence is that regulatory scoping must now begin at or before the LOI stage, not after signing.
• Expanded merger‑control scrutiny. The Bundeskartellamt has signalled greater attention to concentrations in digital markets and adjacent sectors. Parties should expect more Phase II investigations and proactive information requests. Pre‑notification dialogue is increasingly advisable.

For deal sequencing, this means the regulatory‑scoping step (Step 2 above) should run in parallel with, or even before, early commercial scoping. Transaction documents (LOIs and SPAs) must include robust regulatory conditionality, longstop dates calibrated to extended review windows, and break‑fee mechanisms that reflect the higher risk of prolonged review.

Common Pitfalls in the Unternehmensnachfolge Process and How to Avoid Them

• Late or missing FDI / merger‑control filing. Closing a notifiable transaction without clearance can result in fines, unwinding orders or void transactions. Mitigation: complete regulatory scoping in Step 2 and include clearance conditions in every SPA.
• Poor works‑council timing. Failing to consult the works council early enough can trigger disputes or delay closing. Mitigation: align a confidentiality protocol with the works‑council briefing timetable and start consultation concurrently with deal negotiation.
• Defective notarisation. A GmbH share transfer without proper notarisation is void. If a representative signs, the power of attorney must also be notarised. Mitigation: engage the notary early and verify all signing authorities before the appointment date.
• ErbStG relief clawback. Business‑succession tax reliefs can be lost if holdover conditions are breached, for example, by reducing headcount or ceasing operations within the holdover period. Mitigation: map holdover conditions before closing and build compliance obligations into post‑closing governance.
• Delayed Handelsregister update. Failure to file the updated shareholder list promptly after notarisation creates an inaccurate public record and can complicate subsequent corporate actions. Mitigation: instruct the notary to file immediately upon completion of the notarised transfer.
