Start with what you already know about the property: earlier work, known problems and documents you are unsure about. You do not need a fixed sale date to put things in order. Some questions need replies from the municipality or professionals and are easier to address before the sale becomes urgent.
List the alterations
Walk through the home and note rooms, extensions and technical installations changed during your ownership. Include older changes you know about. Record who carried out the work and where documents might be found, without filling gaps with guesses.
Gather invoices, descriptions of completed work, drawings, permissions and relevant correspondence. Invoices can describe the work carried out. Municipal permits and approved drawings show what was considered in the building case.
Clarify room use and missing records
Compare current use with approved drawings. A room used as a bedroom may be labelled as storage in older records. Check for later approval before describing the issue as settled or unlawful. If an alteration needs an application, the possibilities require assessment of the specific circumstances.
Where a completion certificate is missing, find the building case and application date. Do not rely on the age of the house alone. See the missing completion certificate guide for separating the documents and questions.
Make the information understandable
Prepare a short list of known matters and connect each to its available evidence. Distinguish confirmed information from questions still being examined. Give the estate agent and building professional a coherent set of records, and add new answers to the same overview.
Forbrukerrådet emphasises accurate information and careful checking of sale documents. If you are unsure whether a known issue needs describing, raise it with the estate agent and building professional before publication. This helps make the sales information clear and accurate.
Help with one task or the full review
You may need help requesting one archive file, understanding a decision or following several questions at once. Budsjekk helps gather the information and organise next steps, including where a problem was known at purchase or has existed for years.
A review may show that an application, technical assessment or better records are needed. We help you find out what is needed for your home.
