Legal Question in Real Estate Law in California

Re: landlord harassment

If your rental agreement forbids any roommates, and if your boyfriend moved in you can be in trouble. Arguably, the landlord needs to give you three days to get him out, and if there is no live in boyfriend or he is out, you should be able to stay.

There is no sexual harassment if the landlord simply wants to date you. There may be sexual harassment if the landlord threatens to evict you unless you date him.

Regarding the 3 day notice to pay rent. If he lost the money order, and your are aware of it, you should get the money order cancelled and replaced. Although he lost it, you are able to resolve the problem. Offer to help with a witness present (in case you have to go to court.)

You probably don't have very good grounds to sue your landlord. It does not appear you have suffered any damages, and he likely has a different version of the story. You would have a hard time convincing a lawyer to take this case, based on what you stated here.

Finally, don't be so stupid as to let your boyfriend shack up with you - unless you don't care about having a stable normal family life. People who shack up rarely stick it out and the women are almost always the big losers, especially if there are children. There is no 100% safe birth control, so you may be making children who may not have a father. That is a bum rap for the kids and for you.
