It may seem obvious but the easiest way to find out if someone is married is by asking them outright. Of course if you're asking your new boyfriend that you met last night he might just want to conceal the fact if he is married.

It's not an exact science but if you study your new partner closely and ask the right searching questions then it's often very easy to tell whether they are lying to you. If someone is about to lie to you they will often look away and upwards to avoid making eye contact with you.

People often become visibly uncomfortable when they are lying, another tell tale sign of dishonesty. They might shuffle in their seat, stumble over their words and blush. I know that I go bright red when I'm trying to conceal the truth from someone which is a dead giveaway. I'm a hopeless liar so I avoid it.

You don't need to ask questions directly about their marital status either. Just keep asking all sorts of questions and listen carefully to the replies. If someone isn't telling you the whole truth then sooner or later they are going to slip up and say something which you know is absolutely a lie. As soon as that happens you can't trust anything else they've told you and it's time to walk away.

It's simple but effective: Find out if someone is married by asking them. If you're in any way suspicious or you need a little more reassurance you can use an online service to find out if they're married.
