Should It Be A Hostile Takeover Or Not? Over This Church My Grandmother Helped Create

Me grandmother and her long time friends bought a church in the early 90s all of them own it and none of them attend the church after the Main leader died . Now two members are only attending the church and have been the only ones with access to the church . Now upon us asking for use of the church we were met with nastiness and mean spirited people. So we decided to contact a lawyer to see what are legal rights are do we sell the building and give the investors their money back or do we agreeably use the building as a collective ?

I’m in Omaha Nebraska btw if that helps
