I was reading Father John Dietzen's column carried by the Catholic News Service the other day. He answers questions from readers. One woman asked whether her sister-in-law could have a Catholic funeral. She was baptized Protestant but attended Catholic Mass with her husband for 62 years.
He answered: "According to Catholic regulations, baptized Christians who are not members of the Catholic faith may have the funeral rites of the Catholic Church, including Mass, provided the person did not object to a Catholic funeral and that her own minister is not available. . . Even if she were not a baptized Christian, a funeral liturgy could be held for her in the Catholic church she attended, with Scripture readings, prayers, homily and other devotions, excluding the celebration of the Eucharist. These provisions are found in canon law (1183) and the 1993 Directory for Ecumenism (120)."
I hadn't known that this was the case, and thought it might be important information for others to be aware of as well.
