There are many so called rules to follow when doing tarot readings; here are a few of the must haves.
The querent(the person getting the tarot reading) may tell you intimate details during the reading and will want you to keep that information private and as a tarot reader you must respect their wishes and privacy. Sometimes you may hear from a querent that they have done something illegal; in this case as a tarot reader you would not maintain querent confidentiality. These cases would be something of this nature...
1. The querent is indicating that they want to commit suicide. In this case you will want to encourage them to talk to a doctor or go straight to the emergency room for help, you may want to call a close friend or family member to come get them as you explain what you have just been told, do not leave this person alone.
2. The querent just informs you their intent to kill or harm someone illegally. It will be appropriate to inform the police, this way it may protect you the tarot reader from possibly be seen as an accomplice or an accessory to the crime.
3. The querent admits to a horrible crime such as murder or rape. Again, call the police as soon possible.
4. The querent states that they are a victim in a crime, that they were raped or abused or beaten. Call the police or a social worker and get the querent help especially if the querent is a minor.
In normal readings, you are not permitted to discuss a reading with another individual for someone else's reading.
If a querent comes to you for a reading about their health, be careful as you can not give medical advice. If someone comes up in a reading about the querents health, direct the person to seek a professional to get proper medical attention.
Taking payment for a reading:
It is fine to charge a small fee but it is unethical to manipulate or scare a client into paying for bogus services such as removing a curse. Also when a client becomes dependent on you for readings, you should not encourage this addictive behaviour.
Reading for a third party:
Most of the time this is not an issue but there will be times when a person comes to you and wants you to be a 'psychic spy' on their spouse or a distraught parent wants to know what their teenager is really doing and with whom or what they are involved in. These times are very difficult since it is involving someone else's privacy. If you do choose to do these readings, change the question so that it is put back onto the client. Such as "My husband has been acting different towards me why? and is he cheating?" You can turn this around like "What can I do about the way my husband is behaving?" And for the worried parent's question of "Is my teenage son doing drugs?" you can put it like "What is the outcome of my relationship with my son?"
Reading for minors:
There are parents who want to introduce the tarot to their children at an early age, you do have the right to deny these readings. If you chose to do readings for ages under eighteen use a story base instead of talking 'to' them. Make sure your grammar is appropriately for their age.
Above all else:
You as a tarot reader must uphold the integrity of the tarot as an enduring source of spiritual guidance and to pursue your own personal, spiritual and emotional development.
