The diocese of Pittsburgh in the United States has eliminated all fees for marriage annulments.
Bishop David Zubik said Pope Francis had inspired the move by calling for marriage tribunals to do justice swiftly.
The Pope expressed a desire for no-cost annulments last year.
Pittsburgh church officials had been collecting about US$120,000 annually in annulment fees — but that was only about one-third of the full cost.
The diocese will cover annulment costs through a combination of grants from a recent capital campaign and operating funds through its Parish Share programme.
Most dioceses in Pennsylvania offer financial aid for low-income petitioners for annulments.
