婚姻一方出轨如何取证（一方婚内出轨）

发现另一半出轨后，如何进行证据搜集呢？

捉奸尽可能邀伴同行

有些当事人出于家丑不外扬或者其他原因，知道对方在与他人通奸时，自己一个人去逮。这样的结果，一旦涉讼，当事人所看到一切，在法律上仅是相当于当事人陈述，只要对方否认，则不能认定。

当知道对方准备或者正在与他人通奸时，尽可能邀请二到三个愿意出庭作证的人一起前往捉奸，并尽可能用照相、录音、摄像等方式作好影像记录。

尽可能多地收集间接证据，形成完整证据链

在现实生活中，能够取得“捉奸在床”的直接证据少之又少，往往需要收集尽可能多的间接证据。

如：qq或微信聊天记录、电话记录、短信内容、电子或纸质书信、两人在公共场合较为亲密的照片、一起旅游的合影、租房合同、物业和水电费凭据、开房记录、票据、视听资料、证人证言、互赠礼物、村(居)委会、派出所的证明等等，这些间接证据单独一样一般无法成立，但如果综合起来形成证据锁链，则可认定事实成立。

对易消失、更改的证据及时保全、固定

有些证据可能是稍纵即逝的，比如通奸现场等无法再现的场景，可以通过请求公权介入做笔录的方式固定，比如电子版、手机短信类容易被删改的证据，一旦取得最好及时通过公证的方式保全，这样，即使对方以后删除或者更改，也不受影响。

监听监视须谨慎

一些当事人为了取得另一半方不忠的证据，通过不正当途径采购、安装监听和监视设备，而我国法律对这些设备的使用有严格的法律规定，稍有不慎则可能会违反相关法律。

最终不仅因为取证违法所取得的证据不被采信，还可能因为侵害第三方的民事权利而承担相应的民事责任，甚至可能让自己承担行政以及刑事责任。

适当借助公权

当事人擅自闯入他人住宅取证，一方面可能引发侵权责任，另一方面也可能会导致所取得的证据不被采信，或者证明力低下等。有时候，适当借助公权介入不失为一种好办法。 　

跟踪另一半与第三者，看到他们在宾馆开房进了房间，怎么办？建议打110报警，说明自己看到另一半跟陌生人正在宾馆开房，怀疑是在卖淫嫖娼，但因为自己一个弱女子，如果硬闯进去怕人身安全受威胁同时也担心引发其他法律责任，需要求助警察介入。

证明“以夫妻名义”同居的思路

根据法律规定，重婚罪的构成要求双方是以夫妻名义同居且周围的人也认为其为夫妻，而我国刑法规定的重婚罪又是自诉案件，即需要控诉一方当事人自己去完成举证，公权力一般不主动介入，举证的难度极大。

现实生活中，重婚取证一般会有：以夫妻名义申报户口、购买及租赁住房、举行婚礼等。我国婚姻登记与户籍登记并未联网，往往会出现登记结婚了户口上仍为未婚的情形，这样就可能出现登记后的一方，又异地与他人登记结婚，如果同时调取到两份结婚证，这就是确凿的直接证据，但现实中这种情况并不多见。

除此之外，就需要调取同居双方其他方面的证据，比如：对外以“老公老婆”介绍身份，以夫妻名义旅游聚会；邻居和亲友证言；如果与第三者生育子女，双方以配偶身份签字或者小孩出生医学证明记载双方为父母亲等。

法庭调查中巧妙发问，确认相关事实

根据法律，如果一方当事人承认的事实，可以免除另一方的举证责任。如果经过前述努力，仍无法取得足够证据，也不要悲观泄气。

有时利用法庭调查中互相发问环节，通过巧妙的问话设计，让对方在回答问题中承认相关事实或者将本不完整的证据链补充完整起来，也可能会取得意想不到的效果。

当然，这种效果的取得，需要发问者有丰富的经验和高超的技巧，而且还带有很大的偶然性。

How do you gather evidence when you find your partner cheating?

1, catch adultery as far as possible invite a companion

Some parties, for reasons of keeping their dirty linen in the closet or other reasons, know that the other party is committing adultery with others, and they go to catch themselves. Such a result, once involved in the litigation, what the parties saw is only equivalent to the statement of the parties in law, and as long as the other party denies it, it cannot be identified.

When knowing that the other party is preparing or is committing adultery with others, as far as possible to invite two to three people willing to testify in court to catch the adultery, and as far as possible with photography, recording, videography and other ways to make video records.

2. Collect circumstantial evidence as much as possible to form a complete evidence chain

In real life, there is very little direct evidence that can be obtained to "catch adultery in bed", and it is often necessary to collect as much circumstantial evidence as possible.

Such as: Qq or WeChat chat records, phone records, text messages, electronic or paper letters, two people more intimate photos, travel together in public utilities, rent contract, property and the photo of the credential, margie, records, paper, audio-visual material, the testimony of witnesses, gifts, village (house) commission, police station proof and so on, These circumstantial evidence alone cannot be established generally, but if they are combined together to form a chain of evidence, the fact can be established.

3, the evidence that is easy to disappear and change should be preserved and fixed in time

Some evidence may be fleeting, such as adultery site not reproduce the scene, can do it by request the public power intervention in the record of fixed, such as electronic evidence, mobile phone text messages are easy to be deleted, once has the best preservation by means of notarization in time, in this way, even if the other party after delete or change, also not be affected.

Listening and monitoring should be careful

In order to obtain evidence of infidelity, some parties improperly purchase and install wiretapping and surveillance equipment. However, Chinese law has strict rules on the use of such equipment, and any indiscretion may violate relevant laws.

In the end, not only is the evidence obtained by illegal evidence collection inadmissible, but also may bear the corresponding civil liability for infringing the civil rights of the third party, and may even make oneself bear the administrative and criminal liability.

Appropriate recourse to public authority

On the one hand, the parties may cause tort liability, on the other hand, the obtained evidence may not be accepted, or the proof force is low. Sometimes it is a good idea to intervene with the proper help of public authority.

What if you follow your partner and a third person and see them in a hotel room? Suggest to call 110 to report to the police, explain oneself to see the other half and the stranger is in the hotel to open a room, suspect is in prostitution whongs, but because oneself a weak woman, if hard break in to fear personal safety is threatened at the same time also worry about causing other legal responsibility, need to ask for help police intervention.

Prove the idea of cohabitation "in the name of husband and wife"

According to the law, the constitution of the crime of bigamy requires both parties to cohabitate in the name of husband and wife and the people around them also consider them as husband and wife. However, according to the criminal law of China, the crime of bigamy is a case of private prosecution, that is, the litigant needs to complete the proof by himself, and the public power generally does not take the initiative to interfere, so the proof is extremely difficult.

In real life, bigamy evidence will generally have: in the name of the husband and wife to declare the registered permanent residence, buy and rent housing, wedding, etc. Marriage registration and household registration in China are not connected to the Internet, and often there will be the situation that the registered marriage is still unmarried on the household registration, so there may be one party after the registration, and the registration of marriage with others in other places. If two marriage certificates are obtained at the same time, this is conclusive direct evidence, but in reality, this situation is not rare.

In addition, it is necessary to take evidence of other aspects of cohabitation, such as: to introduce the identity of "husband and wife", travel parties in the name of husband and wife; Testimonies of neighbors and relatives; If a child is born with a third party, both parties shall sign as spouses or the medical certificate of the child's birth records both parties as parents, etc.

7. Ask questions in court investigation and confirm relevant facts

According to the law, if one party admits the fact, the other party can be relieved of the burden of proof. Don't get discouraged if you don't have enough evidence.

Sometimes by using the questioning link between each other in the court investigation, through clever questioning design, let the other party admit the relevant facts in the answer to the question or complete the incomplete evidence chain, may also achieve unexpected results.

This effect, of course, requires a lot of experience and skill on the part of the questioner, and also involves a lot of chance.
