Selling a property in 2025 represents a major step marked by a series of essential administrative and legal procedures. More than just a transaction, it involves physical and legal responsibilities that must be anticipated to ensure the security of both the seller and the buyer. The notary plays a central role, both during the drafting of the deed and for all formalities following signing, such as registering the sale and land registration. Furthermore, the seller must take into account important tax aspects, including the declaration of capital gains and the possible payment of property tax. These steps are supported by real estate appraisal services and platforms dedicated to document and insurance management, to guide the various phases. This process, beyond the simple transfer of ownership, requires precise coordination to meet legal deadlines, guarantee payment security, and ensure the proper transfer of rights within a constantly evolving legal framework. In 2025, increasing digitalization and the support of specialized real estate agencies will also facilitate these complex steps.
Essential administrative formalities after signing the real estate sales deed
Once the deed of sale is signed, a series of administrative formalities must be completed by the notary and the seller. This process ensures the legal and fiscal continuity of the transaction. The notary plays a pivotal role here, notably by registering the sale with the mortgage office, also known as the conservation of mortgages, which makes the sale binding on all parties.
The notary must:
- Provide a copy of the deed of sale and the certificate of ownership to the seller and the buyer.
- Register the deed with the land registry office within the legal period of one month from the signing.
- Submit the transfer declaration to the land registry office, making the transaction irreversible for third parties.
At the same time, it is advisable for the seller to inform their home insurance company of the sale so that the contract can be terminated or transferred according to the agreed terms, thus avoiding any unnecessary costs. In addition, it will be advisable to notify the condominium association if the property is co-owned, to update the lists and facilitate future management of the building.
