The fastest digital interface between authorities and the real estate industry

Official authority disclosures for real estate are formal documents and information issued by public authorities that confirm a property’s legal, structural, and planning status. They are essential for identifying risks early and making informed decisions when buying, selling, or developing a property.

Official authority disclosures fall into six categories:

• Permit documents: e.g. building permits for the original construction, later structural changes such as an added story or an extension. Changes of use also require building-law approval. Key documents include building permits, permit decisions, floor area calculations, building descriptions, and plans such as floor plans, elevations, sections, and site plans.
• Encumbrances and restrictions: e.g. contaminated sites, building encumbrances, historic preservation status, unexploded ordnance records
• Neighbor contributions: e.g. the contribution certificate covering development levies and sewer connection fees, or municipal charges — see the development contribution certificate
• Geo and cadastral data: e.g. cadastral map, land registry map, property records
• Tax information: e.g. property tax assessment, tax clearance certificate
• Planning-law disclosures: e.g. development plan (B-Plan), land use plan (FNP), conservation area statutes and further ordinances under the German Building Code (BauGB)

Official authority disclosures are critical when buying property, as they reveal legal risks, usage restrictions, and potential financial burdens early on. If key information is missing, banks may require additional collateral as part of the financing process or limit the purchase price they will finance. This can also affect the interest rate offered.

At the same time, official authority disclosures can reveal value-enhancing potential: development plans and planning-law disclosures, for example, show whether further densification or additional construction is possible — which directly affects a property’s market value.

Skipping official authority disclosures exposes buyers to significant legal and financial risks. Undisclosed building encumbrances or unauthorized construction can lead to usage restrictions and, in extreme cases, force the unwinding of the purchase contract.

Banks also respond to missing documentation: they often demand additional collateral or reduce the loan-to-value ratio, making financing more expensive or causing it to fall through. On top of that, value-enhancing development potential can go unnoticed if planning-law information is missing.

The information needed for a property is typically spread across various authorities and departments and must be requested individually. For commercial properties in particular, this often means dozens of separate requests — frequently more than 20 per property.

These include building authorities, cadastral offices, and environmental agencies, among others. Each authority has its own responsibilities, submission requirements (e.g. email, form, or postal mail), and processing times.

In some cases, an in-person review is required, for instance of building or land files, adding further effort.

Once a request is submitted, processing status is often opaque, creating extra coordination and follow-up work. At the same time, errors — such as inaccurate property data — can cause delays or require resubmission.

On top of that, many disclosures come with separate fee notices that must be paid on time and booked internally. Altogether, this creates a complex, time-intensive, and error-prone process that is difficult to manage efficiently without central coordination.

Efficiency in procuring official authority disclosures comes from central coordination of all requests, standardized digital processes, and a structured consolidation of results.

DocEstate acts as the digital interface between the real estate industry and public authorities, handling the entire coordination process. All relevant disclosures are procured in bulk, authority fees are settled centrally, and results are delivered in a structured format. In addition, the information from these disclosures is cross-checked against further data in a combined analysis. This significantly reduces internal effort and speeds up downstream processes such as transactions, valuations, or financing.

DocEstate is the central partner for official authority disclosures in the real estate industry and the direct digital interface to building archives, building authorities, cadastral offices, and other public authorities across Germany.

Instead of submitting numerous individual requests to different authorities, all disclosures are procured in bulk through DocEstate. Authority fees are settled centrally, resulting in a single invoice. DocEstate also systematically evaluates the results, supplements them with data from further sources, and presents opportunities and risks in a clearly structured report — providing a well-founded basis for decisions on acquisitions, development, or financing.

All official authority disclosures and analyses are made available centrally through your personal area on the DocEstate platform. Documents are accessible at any time, structured for clarity, and secured with different access rights for internal and external stakeholders.

For full process automation, disclosures can be transferred directly into your own software systems via the DocEstate API. Seamless integration into existing platforms such as data rooms, CRM systems, or valuation tools has already been implemented for leading providers including OnOffice, Backbone, and Empro.

DocEstate significantly reduces the time needed to obtain official authority disclosures. In many cases, data is available up to 14 days earlier than with manual applications. Depending on the scope of disclosures required, up to 27 hours of internal effort per property can be saved.

Since transactions, financing, and development projects often depend on the availability of official information, DocEstate measurably speeds up the entire process and enables faster deal closings.

DocEstate is designed for all professional players in the real estate industry who regularly need property analyses based on validated data, whether for ongoing operations or transactions:

• Real estate investors and asset managers: for due diligence and acquisition reviews
• Real estate agents: for sales documentation and client materials
• Banks and lending institutions: for loan-to-value assessments and financing approvals
• Notaries and attorneys: for drafting purchase contracts and transferring ownership
• Appraisers and surveyors: for market value appraisals under ImmoWertV
• Developers and project builders: for planning law and permit documentation

The contaminated sites register is the municipality’s official record of known contaminated sites and harmful soil changes on properties. A contaminated site disclosure is the extract from this register for a specific property.

Contaminated sites can significantly reduce a property’s value and may trigger remediation obligations under the German Federal Soil Protection Act (BBodSchG). Banks frequently require a current contaminated site disclosure for property financing. A legitimate interest must be demonstrated to request one. Contaminated site disclosures are regularly factored into DocEstate’s analyses.

A building encumbrance disclosure is an extract from the building encumbrance register held by the responsible building authority. It documents public-law obligations of the property owner toward the building authority that can significantly restrict a property’s value and usability.

A building encumbrance disclosure is needed when buying property, when financing through a bank, and during building permit procedures. Typical encumbrances include setback area encumbrances, access-way encumbrances, or obligations to keep certain areas of a property clear. Processing time ranges from 1 to 8 weeks depending on the authority.
