Although Buddhist lay people might be interested in having a monk perform their marriage ceremony, it is not allowed and doing so is classed as a heavy rule (Saṅghādisesa). Such heavy rules have penalties and require the monk to lose his full status for a minimum of 6 nights1 and additional probation time if concealing the offense occurs.
