Lord’s Prayer; Forgive us our debts or our trespasses?

When our family prays the Lord’s Prayer we have always used, “forgive us our *debts*” instead of “*trespasses*”. This is because the first Bible I attained used the word. (KJV) Our family has no denomination and as such are unsure as to how others pray the Lord’s Prayer. Which Christians are likely to use one or the other?
