Incomplete documentation rarely improves under deadline pressure. Organising property and party information early helps identify discrepancies between the physical asset, records and expectations before there is pressure to complete.

In this guide

  • Confirm identity, ownership and property description.
  • Gather applicable use and energy-performance documents.
  • Record conditions, timing and responsibilities clearly.
  • Validate the final list with the professionals handling completion.

1. Information the seller should start gathering

The exact list varies, but a process commonly starts with identification of the parties, tax record, land registry information, energy certificate and documents related to the authorised use of the property.

Plans, technical records where available, condominium information, completed works, warranties, contracts or other documents linked to the asset may also be relevant.

  • Owner identification
  • Tax and land registry records
  • Energy certificate
  • Applicable use documentation
  • Condominium and relevant works information

2. What the buyer should confirm

Compare the property visited with the available records. Areas, storage, parking, use, charges and alterations require attention when they affect the decision.

Where financing is involved, align the transaction timeline with valuation and bank approval. Document checks do not replace a technical inspection when the property’s condition warrants one.

3. Before formalising an agreement

Price, deposit, deadlines, financing, included items, handover, conditions and consequences of default should be understood before signing. Vague wording creates different interpretations.

The parties should know who prepares and reviews each document, which checks remain and what must be completed before completion.

4. Prepare for completion

Confirm the case-specific list with the notary, lawyer, solicitor, registry or service responsible. Casa Pronta can combine several procedures related to a property acquisition and registration.

Keep current versions and organise proof of relevant payments and communications. A checklist supports preparation; professional validation closes the gaps specific to the transaction.

Useful official sources

Check current information with the relevant authorities before making decisions.

Required documents depend on the property, parties, financing and transaction type. Always confirm the specific case with qualified professionals.
