They are not husband and wife, but they often go out to live together. Is it illegal?

Definitely not illegal. How many couples go out to stay in hotels now? If this situation is illegal, it is estimated that many people will be arrested.

However, it should be noted that both parties need to show their ID cards when staying in the hotel. If one party is under the age of 18, it is illegal to have sex while living with the opposite sex, regardless of whether both parties want to.

Our society is very open now, unlike in the past when we had to get two marriage certificates to stay in a hotel. Now even if it's not husband and wife, it's okay to share a room together. For the hotel, it doesn't matter what the relationship is, because the purpose of the hotel is to make a profit. He just needs to ask the other party to provide the documents he needs. Whatever it is, it has nothing to do with the hotel. And there is no law that requires couples to stay in hotels. Therefore, as long as two people don't do something illegal, no matter what the relationship is, they can live together.

Of course, at this time, some people will ask, will the police in modern society come to make rounds at night as before? Of course, but it's not the same as before. Now the police only check whether they have done some sex trade and so on. I don't care about lovers, mistresses and the like. The police just look at the ID card to verify their identity, and there will be no punishment.

Even if one of them is married, it is not illegal for them to live together. Moreover, this kind of thing often happens in modern society, which can only be condemned by morality and will not be punished in any legal sense.

Although it is not illegal for husband and wife to live together, we are all adults now. No matter what we do, we have to pay a certain price. We can't do whatever we want. We already know what to do and what not to do. This is also a sign of being responsible for yourself.
