Yes, imafan26 is right! Make sure that your pot has drainage holes. If not, make sure to repot the palm into a pot with draining holes at the bottom so that you can check and see when you should stop watering it.
Indoor palms are quite hard to look after...the soil can't be too wet nor can it be too dry
I would suggest watering once or twice a week. I water my two palm trees every Wednesday and Saturday every week. And use fertilizer once a month.
