The problem of parents and children has been relevant probably as long as humanity has existed. Do you really think that Cain would have taken Abel's life if he had not experienced certain complexes - quite possibly because of an undeveloped relationship with his father?
And when it is also a stepfather, then no matter how wonderful the child's relationship with him, in any case, there will be some conflicts. And if another child from another marriage is involved, it is even more certain. And it will take a lot of psychological maturity and wisdom from both parents to properly solve this problem without any harm.
The author of a popular post in the AITA Reddit community, which has already gained almost 8.7K upvotes and more than 1.3K various comments, faced such a problem. And, unlike the value judgments typical of this community, here, the Original Poster received some really wholesome advice.

The Original Poster lives with his wife, her 12 Y.O. son, and his 11 Y.O. daughter

So the OP lives with his wife, his 11 Y.O. daughter and 12 Y.O. stepson. The boy and the girl, according to the author of the post, get along well, but from time to time, like almost all children, they fight among themselves and annoy each other in every possible way.

The OP's stepson has made a habit of sneaking into his stepsister's room and taking her things
The OP's stepson has made a habit of sneaking into the girl's room and taking things from her - like a T-shirt, favorite pen, teddy bear, etc. The OP has told him more than once that this behavior is unacceptable and that next time he will be punished. The boy promised that he would not do this again - but time passed, and everything repeated.

The OP imposed punishments, especially by making him do chores
As a result, the stepfather began to really punish the preteen. Mostly by having him do chores: taking out the trash for a whole week, washing the car, and mowing the lawn with his stepfather (which the boy especially did not like). For a while, the stepson stopped upsetting the sister, and the OP decided that everything was fine.

On the eve of his best friend's birthday, the stepson stole the girl's diary from her room
But now, on the eve of his best friend's birthday, to whose party OP's stepson was, of course, invited and really wanted to go, he again entered the room of OP's daughter and stole her diary. This time, the OP and his wife specifically called both children and decided to have an educational conversation.

The parents agreed that they have to be more strict now
The wife agreed that her son should be punished and suggested that he wash all the dishes in the house. The husband did not agree with her, arguing that this is not the first time the boy has behaved badly, so they need to be more strict.
True, the stepson, in justification, said that the girl annoys him and also sometimes deliberately infuriates him. The OP objected that in this case, she also receives punishment, and that they are one family and should get along well.

The boy yelled at his stepdad that this was his house, not the man's
The stepfather said that from now on, the boy has no right to enter the room of his stepsister without her permission. In response, the boy yelled that this was his house (and indeed, when the OP and his wife tied the knot, he and his daughter moved into the woman's house), and that he would go anywhere he wants at any time he wants.

As a result, the boy was punished even more - instead of having a party with his best friend, he had to clean the whole house that evening. Of course, the stepson was incredibly upset, and the wife later told the OP that he was too tough.
People in the comments mainly supported the OP, though some of them suggested visiting a family psychologist
True, the commenters mostly supported the OP, arguing that impudence and disobedience, of course, should be punished - although, of course, this man should visit a family psychologist in order to improve relations in his family.
In any case, the OP also received some valuable parenting advice based largely on the commenters' personal examples, for instance, that the punishment should correspond to the offense. Like if the stepson steals something, he must in return lose some of his things.
Of course, we are not family psychologists, but we encourage you to also discuss this situation. It is likely that you yourself have been in either OP's or his stepson's place, and then, of course, it will be very interesting to know how your similar story ended.
