Buying an Apartment in Paris: Why Due Diligence Means Looking Beyond the Documents

When buying property in Paris, the most important information is not always in the documents you receive. At Tomette Paris®, we believe that thorough due diligence means asking the right questions, investigating further, and looking beyond the obvious.

Buying an apartment in Paris is an exciting prospect. You find the right neighborhood, fall in love with the apartment, and start imagining your life there. Then comes the paperwork: the copropriété meeting minutes, technical diagnostics, financial statements, and legal documents that form part of the purchase process.

Reviewing these documents is essential. But is reading what you have been given enough? In my experience, the answer is no.

At Tomette Paris, due diligence is taken seriously. And sometimes, the most important discovery comes from looking somewhere you were not initially expected to look.

🥐 When the Information isn't in the Meeting Minutes

During a recent property search, I was conducting due diligence on an apartment my clients were considering buying in Paris.

While investigating the property and its surrounding environment, I discovered information concerning structural concerns in the neighboring building. These concerns involved party walls and raised questions about potential implications for the building my clients were considering.

What made this discovery particularly significant was that the issue was not mentioned in the copropriété meeting minutes of the building where my clients wanted to buy. It had not been brought to my attention by the real estate agent either.

Had I limited my review to the documents provided for the apartment, I might not have discovered it.

Instead, I investigated further, researched the situation affecting the neighboring building, and contacted the notaire to clarify the potential implications for my clients' purchase.

The purpose was not to assume that the property was unsafe or that the neighboring building's problems necessarily affected it. It was to establish what was known, understand the potential risks, and obtain the information needed to make an informed decision.

This is what thorough due diligence looks like: not jumping to conclusions, but refusing to leave important questions unanswered.

🥐 What Does Property Due Diligence Really Involve?

When buying an apartment in Paris, due diligence goes beyond checking whether the apartment itself appears to be in good condition.

A property is part of a larger structure: a building, a copropriété, and a neighborhood. Its financial, technical, and legal circumstances can influence both the purchase and the ownership experience that follows.

A thorough review may include several areas:

1. The building and its structural condition

The condition of the apartment is only one part of the picture. The roof, façade, foundations, common areas, and neighboring structures may also deserve attention.

I look for information about planned or completed works, structural concerns, water damage, recurring maintenance issues, and decisions that could lead to significant future expenditure.

Where a potential issue emerges, further investigation may be necessary to establish its nature, extent, and relevance to the property being purchased.

2. The copropriété meeting minutes and financial documents

The minutes of general meetings are an essential source of information. They can reveal works that have been proposed or approved, disputes, maintenance concerns, and decisions affecting the co-owners.

But meeting minutes must be read in context. I also look at available financial information, the building's maintenance history, planned works, and relevant technical reports.

A question raised in a meeting, a project postponed, or an expense that has yet to be approved can warrant further investigation.

And the absence of a reference in the minutes does not necessarily establish that no issue exists.

3. Technical diagnostics and legal documents

French property transactions involve a range of technical diagnostics and legal documents. Depending on the property, these may address energy performance, electrical installations, asbestos, lead, termites, or other matters.

These documents are important, but they have a defined scope. A satisfactory diagnostic does not automatically rule out every possible defect or building-related concern.

The objective is to understand what each document establishes, what it does not establish, and whether additional information or expert advice is warranted.

4. Information beyond the immediate property

Sometimes, the next step is to look outside the apartment's own documentation.

Is there a relevant administrative record? Has a neighboring building been subject to a safety procedure? Is there a known issue involving a shared or adjoining wall? Has information emerged that needs to be clarified with the property manager, the notaire, or a qualified building professional?

These questions are not relevant to every transaction. But when a potential concern arises, investigating it can make a meaningful difference.

🥐 Why my Legal Background Makes a Difference

Before founding Tomette Paris®, I spent 25 years working as a lawyer in international business, compliance, and anti-fraud. That experience shaped the way I approach property purchases today.

In legal and compliance work, you learn not to accept every piece of information at face value. You learn to cross-check facts, identify inconsistencies, distinguish assumptions from evidence, and ask questions when something does not add up.

You also learn that what is missing can be just as important as what is present.

These are habits developed over years of professional practice. They influence how I review property documents, investigate potential concerns, and decide when further clarification is needed. I bring that same mindset to every property search I undertake for my clients.

Of course, legal experience does not replace the expertise of an architect, structural engineer, surveyor, or other qualified professional. My role is to identify potential issues, investigate the available information, ask the right questions, and help my clients obtain the appropriate advice when necessary.

The goal is to ensure that relevant questions are identified before my clients commit to a purchase.

🥐 Due Diligence is About Protecting the Buyer's Interests

As an independent buyer's agent, I represent the buyer's interests throughout the property search and purchase process. I do not have a portfolio of properties to sell.

My role is NOT to persuade clients to buy a particular apartment, but to help them assess whether it is the right purchase for them.

Thorough due diligence can lead to different outcomes. Sometimes, an investigation provides reassurance that a concern is manageable or has already been addressed. Sometimes, it reveals information that can support a price negotiation or help clarify which party is responsible for particular works.

Sometimes, it means obtaining an additional technical opinion before proceeding. And occasionally, the information uncovered may lead a buyer to reconsider the purchase altogether. The objective is to make a decision based on the best information reasonably available.

🥐 Buying Property in Paris with Confidence

For international buyers, purchasing an apartment in Paris can be particularly challenging. The French property system has its own terminology, legal procedures, and copropriété documentation. Much of the information is available only in French, and understanding the implications of a document can be just as important as translating its contents.

Having someone on your side who understands both the legal framework and the practical realities of buying property in Paris can make the process more transparent.

At Tomette Paris®, I combine my legal background, knowledge of the Paris property market, and independent buyer representation to help clients navigate this process with greater clarity.
