When you renounce, you are treated as never having been an heir. But the house itself does not disappear. It stays standing there until someone looks after it and someone disposes of it.
Renouncing an inheritance, once filed with and accepted by the family court, means you take on neither the debts nor the property. If the family home seems worthless, wanting to renounce and cut ties is natural. But what happens to the house afterwards is rarely explained, and that is where the misunderstanding lies.
The revised Civil Code art. 940, in force from 1 April 2023, provides: “A person who has renounced an inheritance, if they are actually in possession of property belonging to the estate at the time of renunciation, must preserve that property with the same care as their own property until it is handed over to the heirs or to the estate administrator.” In other words, even someone who has renounced the inheritance keeps this duty if they were actually using or looking after the family home at the time. They must look after it as carefully as their own home until they hand it to the next person — another heir, or an “administrator” chosen by the court. Before this revision, the article simply said “must continue to manage it,” leaving it unclear who was responsible, and for how long. The revision clarified the scope, according to the Ministry of Justice's explanation.
There are two ways to read this. One: a person who was not occupying the house owes nothing once they renounce. An heir who lives outside the prefecture, has not been back for years and holds neither key nor responsibility is, as a rule, freed of the house by renouncing. The other: a person who lived in the house, or came and went with a key and arranged the mowing and snow removal, keeps the duty to preserve it after renouncing, until it is handed over. The line differs case by case, so check with a judicial scrivener or lawyer.
The duty to preserve is a duty to keep the house from being lost or damaged, not a duty to repair it and raise its value. Even so, houses in Hokuriku carry snow. For anyone with that duty, a winter comes every year in which "I renounced, so it's not my problem" will not do.
What to do while the duty to preserve continues (who to ask for snow removal, draining the pipes and mowing) is in our year-round calendar for managing a vacant house in Toyama from outside the prefecture.
