Complex real estate: tailor-made solutions in the service of science

"Keep this garden. Whatever happens." That was the promise he made to his father. And he never intended to forget it.

This client has lived in the south of France for years. But in Alsace, he still owns 2,500 m² of family garden: his father's, passed on with a single instruction: keep it. A lifelong black truffle enthusiast, he had an idea that was slightly crazy, beautiful and ambitious all at once: to put this garden at the service of science.

A start-up led by researchers is studying the effects of global warming on Tuber melanosporum, the precious black truffle of Périgord. Their question: with climate change, could it one day grow in Alsace?

The project was a fine one. But it needed a legal framework to match. That is where the notaire's role began: not as a mere drafter of deeds, but as the architect of a tailor-made solution.

The owner had a legitimate concern: to whom was he entrusting this garden so full of memories? He knew and trusted the researcher leading the project, but not necessarily the legal structure of the start-up. The solution: the long-term lease (bail emphytéotique) was concluded directly in the researcher's name, with the option for her to make the property available to the start-up within the strictly defined scope of the research.

Every clause of the deed was designed around the project: the scientific objective was written into the heart of the lease. The purpose of the land is legally protected. And the promise made to the father is honoured.

Used with precision, the long-term lease then becomes a tool serving the client's wishes. Its duration, its economics and its purpose are adjusted to guarantee both the stability the research needs and the absolute protection of the property right. The scientific use of the land is secured, any speculative drift is ruled out, and the conditions of use and of return are anticipated.

In this subtle balance, everything rests on a fine line: the law is no longer a constraint, but a precision instrument serving an intention.

At a time when climate challenges force us to rethink our practices, and our assets, some projects fit into no box. They need to be understood before being structured, listened to before being formalised.

This case shows what the notarial profession can offer beyond the usual framework: it is not only about drafting deeds. It is about listening to a story, understanding what really matters to the people who place their trust in the notaire (a promise, a passion, a concern) and building a legal framework that reflects them.

Practised with care and creativity, notarial law can serve extraordinary projects. Even a dream: to see the black truffle flourish one day in Alsace.
