Selling property to family, neighbours or acquaintances

Article L-0037 · 12.09.2026 · 7 min read · Joé Christian Ewrard

Why the supposedly straightforward sale so often goes wrong

When selling to people they do not know, both parties expect negotiations. Documents are reviewed, assurances are questioned and outstanding matters are clarified. Among relatives, neighbours or acquaintances, this approach can quickly feel unnecessarily formal. Nobody wants to give the impression that they distrust the other person.

This is where the risk begins. The seller assumes that the buyer knows the house and its particular features. The buyer believes that a good acquaintance will voluntarily inform them of every problem. Both discuss the purchase price, but not the fitted kitchen, a damp basement room, the shared driveway or the preferred handover date.

As long as there is agreement, this is barely noticeable. It becomes a problem when financing takes longer, a repair becomes necessary or family members question the agreed price. At that point, more than just financial interests are at odds. Suddenly, it is also about disappointed trust and promises perceived to have been broken.

A properly drafted agreement is therefore not a sign of distance. It protects the relationship by making expectations clear. Anything that has been clearly discussed and documented does not later have to be reconstructed from differing recollections.

What must be included in the notarised purchase agreement

A property purchase cannot be validly concluded solely by handshake, private written agreement or email. The obligation to transfer or acquire a property must be notarised. This also applies if the seller and buyer are related or have lived next door to each other for decades. [Section 311b BGB](https://www.gesetze-im-internet.de/bgb/__311b.html)

The draft agreement must include all arrangements that are material to the sale. These include, in particular, the exact property being purchased, the agreed purchase price, the conditions under which it becomes due and the date on which possession, benefits, burdens and risk are to pass. Existing rights recorded in the land register, whether they are to be assumed or discharged, and the vacating of the property must also be addressed unequivocally.

Particular caution should be exercised with supplementary agreements. Statements such as “The furniture will simply stay”, “The seller may continue to use the garage” or “We will settle part of it between ourselves later” may have legal, tax or financing implications. Such arrangements should be disclosed in full to the notary before notarisation. The notary will determine how to incorporate them into the agreement in a legally sound manner.

The notary advises both parties independently and impartially. The notary is not the personal representative of either the seller’s or the buyer’s interests. Anyone requiring a review of risks solely from their own perspective should also consult a lawyer. [Section 14 BNotO](https://www.gesetze-im-internet.de/bnoto/__14.html)

How to agree on the purchase price transparently

Within families in particular, the price is often the most sensitive issue. The seller wants to be fair, but does not want to give away their assets recklessly. The buyer may expect a personal concession. Other family members may later wonder whether someone received preferential treatment.

It should therefore first be clarified how the price was determined. An objective valuation provides a transparent basis for this. It does not compel anyone to sell for a particular amount. However, it shows which features influence the value and whether the agreed price deliberately differs from the fair market value.

A lower family price may be intentional. In that case, this decision should not be concealed behind what appears to be a standard purchase price agreement. Depending on how the transaction is structured, questions relating to gift tax, inheritance law or family law may arise. This applies in particular if siblings, co-heirs, persons entitled to a compulsory share or previous gifts are involved. Tax advisers, the notary and, if necessary, a lawyer should be involved at an early stage.

Nor should the financing be dismissed with a reassuring “It’ll be fine.” An interest in purchasing does not yet constitute secured financing. Sellers should specify when reliable proof of financing must be provided and what happens if the bank does not approve the financing. The purchase price should be paid exclusively through traceable, legally permissible payment channels. Cash, crypto-assets and certain valuables cannot validly satisfy the consideration owed in a property purchase; proof of payment must be provided to the notary handling the transaction. [§ 16a GwG](https://www.gesetze-im-internet.de/gwg_2017/__16a.html)

Which defects and features should be documented

“The buyer knows the house” is not reliable documentation. A neighbour may know the façade and the garden, but not that water enters after heavy rainfall. A child may have grown up in the family home but may know nothing about previous damp, DIY work or a missing permit.

Known material defects and problematic circumstances should be specified clearly. These may include damp, previous damage, pest infestation, materials suspected of containing harmful substances, work not carried out professionally, unauthorised alterations, suspected contaminated land or access that is not legally secured. Uncertain information should also be identified as uncertain. An assumption must not be presented as a verified fact.

For existing properties, liability for material defects is often contractually limited. However, such an exclusion does not protect a seller who fraudulently conceals a defect or has provided a guarantee regarding the property’s condition. Material defects that have been discussed should therefore be disclosed to the notary and, where possible, documented in the purchase agreement. [§ 444 BGB](https://www.gesetze-im-internet.de/bgb/__444.html)

In practice, written documentation of the property and its defects is helpful. It records known damage, work carried out, available invoices and unresolved questions. Photographs, contractors’ documents and previous expert reports should be included in an organised manner. Rather than giving a blanket confirmation that “everything is known,” the buyer receives specific information that can be reviewed.

What needs to be clear regarding handover, inventory and continued use

Many conflicts arise only after the notary appointment. The buyer assumes that they will be able to move in soon. The seller still needs time to move out. The house contains furniture, garden equipment or heating fuel whose fate has not been discussed.

The agreement should therefore specify when the property will be handed over and in what condition. Will it be completely cleared, or will certain items be taken over? Who bears the ongoing costs until handover? What happens to keys, meter readings, documents and existing insurance policies? Are there any tenancy, lease or other occupancy arrangements?

Nor should a right of residence, a usufruct or the continued use of a garage be left to an informal arrangement. Such arrangements can significantly affect the value, financing and subsequent availability of the property. They must be disclosed before notarisation and appropriately formalised by the notary.

For the actual handover, it is advisable to draw up a record signed by both parties. This records the condition, the keys handed over, meter readings, documents and any noticeable changes since the viewing. The record does not replace the purchase agreement. It documents its practical implementation.

What particularly stands out in the Eifel and along the Luxembourg border

In the Eifelkreis Bitburg-Prüm, the Vulkaneifel and rural parts of Trier-Saarburg, properties more frequently comprise more than just the residential building and a clearly defined plot. Outbuildings, old stables, garden areas, multiple parcels of land or shared access roads may also be included. What matters is not what has effectively been used for years, but what is actually being sold and legally secured.

Access is a common point of dispute. The fact that a neighbour has always been permitted to use a road does not automatically mean that a permanently secured right of way exists. The same applies to parking spaces, utility lines, structures built along boundaries or areas that the family has long “considered part of the property”. The land register, cadastral map, building encumbrances and existing permits should therefore be reviewed.

For buyers who work or live in Luxembourg, coordinating the financing may also be more challenging. Income, bank, place of residence and the property being purchased may be subject to different organisational frameworks. This is not an obstacle. However, it is a reason to clarify the financing at an early stage and not to answer tax questions based on the experiences of acquaintances.

Particularly in smaller communities, people remain connected after the sale. Buyers and sellers continue to encounter each other in everyday life. A clear agreement is especially valuable here: it prevents a technical or financial problem from becoming a lasting personal conflict within the community or family.

Which documents are required even without public marketing

A direct buyer eliminates the need for a public search, but not the need to inspect the property. Depending on the property, the documents required include current land register information, cadastral and site documents, construction documents, floor-area details, evidence of modernisation work, information on encumbrances and, where applicable, documents relating to rental or usage arrangements.

The energy performance certificate is still required even if no advertisement is placed. Unless a statutory exemption applies, a valid energy performance certificate must be available for the sale, made accessible to the potential buyer in good time and handed over after the agreement has been concluded. The type of certificate required and whether an exemption applies should be checked for the specific building. [Section 80 GModG](https://www.gesetze-im-internet.de/geg/__80.html)

For condominiums, documents relating to the owners’ association are also required. In inheritance cases, ownership and representation arrangements must be clarified. For land used for agricultural or forestry purposes, additional permits may be relevant. The notary, competent authority or a specialised lawyer can assess what is required in each individual case.

The earlier the documents are complete, the sooner problems become apparent. This also protects the buyer from basing financing and relocation plans on assumptions that later prove to be incorrect.

When an estate agent makes sense despite the buyer already being known

An estate agent does not necessarily have to look for an unrelated buyer. When a property is sold within the owner’s personal circle, the agent’s most important task may be to structure the process. This includes an objective assessment of the property, compiling the documents, recording outstanding issues and preparing the information for the notary’s office.

A neutral person is particularly helpful when the price is an emotionally sensitive matter or several family members are involved. The estate agent does not decide what is fair within the family. However, the agent can explain transparently which property features affect its value and which arrangements are still outstanding.

Experience shows that conflicts often announce themselves through seemingly harmless statements. “We’ll sort that out later,” “He already knows that,” or “Everything will remain as it is” are signs that a clear agreement is lacking. A good process translates these assumptions into specific questions before they lead to a dispute.

An estate agent is not a substitute for legal or tax advice. Drafting the contract is the notary’s responsibility, representing one party’s legal interests is the responsibility of a lawyer, and assessing tax matters is the responsibility of a tax adviser. Good support ensures that these professionals receive complete information in good time.

First, write down all commitments made to date: purchase price, financing, inventory, known defects, handover, continued use, and specific expectations. Then have the property documents and basis of valuation reviewed and pass all agreements on to the notary. PRIOCASA can provide objective preparation for this process in Bitburg, the Eifelkreis Bitburg-Prüm, Trier and Trier-Saarburg, the Vulkaneifel, and along the Luxembourg border, even if you already have a confirmed buyer.

Frequently Asked Questions

Is a private agreement sufficient when selling my house to my child?

No. An agreement to purchase or sell a property must be notarised. A private written agreement can set out preliminary arrangements, but it does not replace the notarised purchase agreement.

Do I have to document known defects in writing even though the buyer knows the house?

Yes, specific documentation is strongly recommended. Disclose any significant known defects openly to the buyer and the notary. A general statement such as “condition known” does not reliably prevent subsequent disputes about what information was available.

Can we make separate arrangements for furniture and the fitted kitchen outside the purchase agreement?

Inform the notary of all agreements relating to the inventory. Whether and how items are included in the purchase agreement or covered by a separate arrangement depends on the individual case. Undisclosed side agreements can cause legal, tax, and financing issues.

Do I need an energy performance certificate if I sell to my neighbour without advertising the property?

Not placing a public advertisement does not generally remove the statutory obligations concerning the energy performance certificate. However, there are exceptions depending on the property. Have the requirements that apply to your property reviewed at an early stage.

Who checks whether a favourable family price has tax implications?

A tax adviser should review this based on the family relationship, the property’s value, and the specific structure of the transaction. If there are implications under inheritance or family law, a notary or lawyer should also be consulted.

Can an estate agent handle only the transaction process if the buyer has already been confirmed?

Yes, support can also be arranged without a buyer search. A valuation, review of the documents, facilitation of discussions, and preparation for the notary appointment are particularly useful. The scope of services and remuneration should be clearly agreed in writing in advance.
