When choosing a celebrant, you should consider their compatibility with your religious or personal beliefs, their experience in officiating ceremonies, and their ability to personalize the ceremony according to your preferences. Ensure that they are legally authorized to conduct weddings in your jurisdiction. A good celebrant will be open to communication, attentive to your needs, and flexible in their approach. It's advisable to meet with them in person or via a virtual meeting to discuss your vision and expectations, and don't hesitate to ask for references or reviews from past clients.
