A Jain wedding can be held in Marrakech without compromise, and the things that need arranging are not the rites. They are the kitchen, which needs to be separate and genuinely so, the clock, because many families do not eat after sunset, and the officiant, because a Jain muni will not be flying anywhere.
Who conducts it
A Jain wedding is conducted by a vidhikarak, a lay officiant, rather than by a muni. Jain ascetics do not travel by vehicle at all, so the question of flying one out does not arise, and it is worth saying plainly early because families occasionally assume otherwise and lose time to it.
Vidhikaraks travel, and most families bring their own rather than looking for one locally. Book the flight at the same time as the pandit's, not later, because they are the one supplier with no substitute.
The kitchen, and what separate has to mean
Jain cooking excludes meat, fish and egg, onion and garlic, and root vegetables, so no potato, carrot or ginger. A Moroccan kitchen is meat heavy by default, which makes cross contamination the real risk rather than intent.
The answer is a kitchen of its own, with its own pans, boards and oil, and cooks who are not moving between it and the main line. That is arranged as a matter of course where a family requires it, and it is specified as counts per event rather than as a note in the file.
Eating before sunset changes the schedule
Where a family observes it, dinner has to be served and finished before sunset, and in Marrakech that is close to seven in the evening in April and nearer six in November. A reception that starts at eight does not work, and the answer is not to rush it but to move it.
In practice that means the main meal sits in the late afternoon and the evening carries the celebration rather than the dinner. It is a better evening for it, and it has to be designed that way from the first schedule rather than corrected in month ten.
What to settle with the venue
Whether alcohol is served on the property at all, and if it is, where. Some families are comfortable with a bar away from the ceremony and dining, others are not, and it is a floor plan decision rather than a drinks decision.
Whether the kitchen can genuinely be given over, with its own entrance if possible. A venue that offers a corner of the main kitchen has not understood the question.
And the timing, in writing. A venue used to European weddings starting at four in the afternoon will schedule staff for an evening service, and a five o'clock dinner has to be in the contract rather than mentioned on the day.
