Ledóchowska's beatification depended on two miracles prior to the 1983 alterations and as such two cases - both in Kraków - were investigated. The first was investigated from 27 September 1971 until 17 February 1972 and the other was investigated from 16 April 1973 until 26 February 1974. These processes received C.C.S. validation on 10 December 1982 before a medical board of experts approved these miracles on 7 April 1983. Theologians likewise issued their approval on 17 May 1983 as did the C.C.S. on 7 June 1983. John Paul II granted the final authorization to it on 9 June 1983 and beatified the late nun while visiting Poznań on 20 June 1983.
