How can you really be sure that someone is not lying to you? Is there a way to really know ?

a good liar will never let you know that they are lying, unless they want you to know

There is no machine by which u can check. Just try to listen and understand him carefully. If he share his things with you, he may be sincere. but there is no hard and fast rules for this.

They have their ways.  Just bring everything and be honest.  Lying or concealing information can get you a denial.

Just make sure whoever it is, that they don't lie.

all people lie; but if you really love someone and feel totally comfortable with that person, you will be able to open up and share things with them that you don't with anybody else.  Evaluate your relationship and if you're letting him express himself without there being a sense of rejection or judgement, if you are creating a safe environment for him and he still lies, he probably will always lie to you and trust is a cornerstone of a healthy relationship.

No there is not.\nIn all of my years of lying and being lied to in various walks of life I've learned that everybody lies, everybody gives it away, and detecting a lie is more detective work than "dead give-away".\nYes there are lots of bodily quirks to pick up on when someone lies. These (like the eyes for example) reflexes really do not indicate a person is lying. They rather indicate that a person is nervous. Very often that is because they are lying but sometimes it is for any one of many other reasons. For example a murderer might pass a lie detector and even fool seasoned detectives, but you might fidget and cry and do all sorts of strange things if the cops stop at your door and ask where you were yesterday even if you were home quietly minding your own business.\nThe truth is to get to the bottom of a lie you have to be aware of what a particular person does when they lie. To do this you must be calculated and patient. \n1.)Wait to be told a lie that you know is a lie and begin to note any significant or slightly unusual behaviours (such as body language and voice tone out of the ordinary).\n2.) Engage the liar in a conversation where you request as much detail about the lie as you can. Make careful note of body language etc., and note the details of the conversation. Sound interested and convinced and you should get enough info for later.\n3.) Be patient. Find more proof.\n4.) You have to wait until the "LIE" surfaces a second time. You can elicit this it can be in the same conversation.\n5.) Make sure you heard right, ask them to repeat the lie. Make note of all body language etc.\n6.) Make a note of time date or other significant information at the time so you can remember enough to be certain for yourself that you know they have been caught.\n7.) Now this is where this all pays off. You sit your liar down and YOU initiate the conversation about any suspected lie. This time you start talking like your convinced and get them to repeat the suspected lie yet again. Watch the body laguage the whole time. You do not ever have to confront them.\n\nPLEASE NOTE:\nThis is a little trick meant to find out what a PARTICULAR PERSON does when they lie. It is meant to help determine the DIFFERENCE BETWEEN nervousness due to lying and other nervous behaviour one might exhibit when they are not lying. It is not meant to find out a lie. The liar always gives it away you just have to figure it out for your own liar.\n\nYou need a lie you know is a lie and they must think you believe it. The more you talk about the lie you know the more you have to watch and see. The more lies you do it with the more accurate you will become. This is something you can do dozens of times with a coworker or nieghbor before you confront them. The more often you do it before confrontation (if you choose confrontation) the more likely  you will be accurate. \nIf you make all of this happen (which could be done with someone you know but probably not a single encounter with a stranger) you should have a solid list of reflexes, behaviours, etc, that you can apply to ONLY THAT PERSON\nYou should be able to have no more than 95% odds that you can detect A person lying. If you want to keep your friends and family don't do this to them.\nYou will be surprised (and not too happy) to know who is really lying to you and about what. But I hope this helps and hope the lie is not too big. \nREMEMBER THE HUMAN MIND IS INCREDIBLE AND NOTHING IS FOOL PROOF.

Has this person ever hurt you before? Lied to you? Gone after something that was yours? Taken something that was not theirs to take? Cheated and you knew about it? Shared a secret you told them? Gone behind your back and told something about you?  If the answer to all these questions are no, then you can pretty much bank on the fact that you have someone you can trust. If the answer to any or most are yes, look very carefully before you leap!!

I agree that asking would not work.  If you try asking here are some clues that he may be lying.  He says "What" when you ask him.  He asks for more details (what do you know) like "When" or "With who", he takes a longer time to respond (he's thinking of a lie), also it has been my experience that people are actually more calm when they lie, think about it if someone asks you if you did something wrong that you didn't do you'd be like "No Way!" and you'd get more agitated if they persisted.  But if you did do this bad thing you'd be kinda calm/monotone/Homer Simpson-like "No, I didn't do that" and you'd get more nervous if they persisted.  I would try spying on him first and see what you can dig up before you go asking questions that make you look distrustful.

There are lie detector tests, Jerry Springer, Murry. You can ask your best friend.You can ask your bf. You can hire a PI.\nBUt if you have a good gut feeling then they probably are.

They are pretty accurate. They can be fooled, but you have to have a lot of self control and know what you are doing to trick it. Most of the time the best people can do is just give inconclusive results, not pass off a lie as truth or vice versa.

The short answer is: they don't.  Many people go through life lying to others and some of these lies end up not being caught.  But when it comes down to it lies won't hold up to intensive investigation and the light of truth.\n\nIf someone has reason to suspect a fact or is curious enough they will eventually be able to find out any mistake, omission or outright lie as evidenced by these proverbs from around the world:\n\nlies walk on short legs.  (german)\none can't stop the spreading of lies with more of them.\na liar is not to be believed, even when he speaks the truth.\n\nhope this helps.

You don't. Everyone lies. Some peolpe lie to protect the ones they love others lie to protect hemselves. And then there are the ones who lie for no reason at all. These are the worst type of liars. Unneccesary lyin gis uncalled for and you should talk to him about this. Honestly though I don't think it is something that will change so you should look fo ra more honest relationship.

As long as you know in your heart it isn't true then God knows it isn't true either. The Bible teaches us "Judge not lest you be judged", sorry I don't remember exactly where to find it. If they are lieing about you then it is them that are casting judgement. That is their problem, not yours. Anyone interested in the truth will ask you about it. It's harder to be an individual than to go with the flow. Lies die but the truth always stands tall. I personally would let them know you know they are the one's spreading the lies and and they can't hurt you with untruths. It's important to forgive them for their mis-speakings then leave the rest in God's hands. He'll take care of them and give them what they deserve in the end. He handles all.\n\nGod has blessed you enabling you to reach out for help. Hold on to that - God's Got It and His victory is so much more sweet!

THERE ARE TIMES WHEN YOU CAN NOT FIND OUT IF A PERSON IS SPEAKING THE TRUTH OR NOT.THEY SOUND SO CONVINCING THAT ITS HARD TO FIND OUT.\nWHILE IN OTHER CASES IF YOU HAVE A DOUBT IF SOMEONE IS LYING TO YOU THEN KEEP ASKING THEM QUESTIONS ABOUT WHAT THEY ARE TALKING AND NOTE THE CHANGE OF VOICE AND THEIR TONE.\nA PERSON WHO LIES TO YOU WILL KEEP STARING AT YOU TRYING TO CONVINCE YOU THAT THEY ARE SPEAKING THE TRUTH OR THEY WILL LOOK DOWN TO THE GROUND.AT THAT POINT THEIR ORIGINAL TONE OF VOICE WILL ALSO CHANGE.\nI HAVE NOTICED THIS WITH MANY PEOPLE.

go with your gut feeling to be on the safe side. usually that feeling is right. if you feel that strongly about someone lying to you, definatly confront them and talk it out. yes that persons going to get upset and deffensive but you have the right to know if you suspect something going on behind your back.

Unfortunately the only way to know if someone is a true genuine friend is time, be protective of yourself, and keep private things to you and the ones you KNOW you can trust, Those who are less genuine are masters at deception and is why many get hurt by trusting too soon. So by knowing this maybe you can keep your self safe from this more often.
