How do I find out if a sussesion has been done ?

If the decedent was domiciled in Louisiana, the proper venue to open his succession would be the state judicial district court in the parish in which he was domiciled on the date of his death. You can find maps of all the Louisiana state judicial districts here: https://www.lasc.org/About/MapsofJudicialDistricts. If you're still in doubt about where the district court is located, you should probably call the general phone number for the Clerk of the Louisiana Supreme Court and ask them for general information. They are not allowed to give you legal advice. Here is the contact information: Clerk of Court:Hon. Veronica O. Koclanes400 Royal StreetNew Orleans, LA 70130P: (504) 310-2300TTY: (504) 310-2546Clerk's Office Email: COCVM@LASC.ORG The easiest way to find out whether the succession has been opened would probably be to go down to the parish courthouse and visit the office of the Clerk of Court. Employees of the clerks' offices are usually very helpful and would probably look up the name for you. If this succession has been opened in that parish, you will be able to actually read all of the documents that have been filed in the case. Remember the saying, "A little learning is a dangerous thing." If property rights are involved (and ALL successions involve property rights), you should consult with a Louisiana attorney so that you don't do something that will adversely affect your rights.
