For any succession: place
The succession opens where the deceased had a principal residence at the time of death, and the Code assigns succession matters to the Court with jurisdiction there.
2015 Code
A source-linked explanation of the provisions that may matter when a succession includes land or a building. Which provisions apply depends on the circumstances. This is not a current filing guide.
Short answer
The available 2015 codes distinguish succession with a will from succession without one. They state rules for accepting or renouncing an inheritance and allow an heir to seek a certificate. If ownership of land or a building passes by will, the Civil Code also requires an entry in the immovable-property register.
The answer depends on the kind of suit described in the 2015 text.
The 2015 Civil Procedure Code says this kind of suit is instituted in the court of the place where the succession opened.
Unless expressly provided otherwise, the 2015 Civil Procedure Code says this listed kind of suit is instituted where the property is situated.
