This is a non-exhaustive list of valid and invalid baptisms in other churches and denominations. Other lists from other dioceses can be found online, a lists from the Archdiocese of Mexico City regarding what they consider as invalid baptisms. It is always a good idea to begin by asking the person who was baptized how (what matter) he/she was baptized and what words (what form) were used by the minister.
