It's better ways to handle that than disrupting a child's birthday party. If they are behind on rent do you think they are going to give it to you there?
Some landlords believe that if they're big enough assholes they can intimidate tenants to paying the rent without calling the authorities. I hate to say it, but it works.
Facebook just reminded me that I was in a rent strike 9 years ago. In response this landlord cut off the power and padlocked the water mains. He also came in with a crew of six guys who took back all the rental furniture, tore the blinds off the windows, cut out all of the electrical outlets and ripped the front door from the hinges.
He also tried to have me arrested on false charges and told the police that I was an illegal immigrant. He sent me multiple threatening text messages saying that I would be deported if I didn't leave or pay rent immediately. On a couple occasions he even threatened my life.
According to the tenancy guide I could have sued him for up to $1,000 over this kind of harassment. Problem was, when I called my former roommates they refuse to go to court. They basically told me "I don't ever want to see that guy again. I was lucky to get out with my life and freedom."
We eventually won the strike, but that assholegot everything he wanted minus a few month's rent.
