Law regarding how much a landlord can charge for a late fee?

I had an email a while ago regarding what my landlord can charge legally for turning in your rent late and now I can’t find it. Does anyone know what it is in the state of California? She is charging 10% of the total rent. Another attorney told me that isn’t legal. I would google it but I have limited internet access. Thanks!

Our renters did not pay rent! How do I evict.?

We rented out our old house, and the lease clearly states that it is due on the 1st. It is now the second and they only gave me $400 of the $600 due. I told them that I would be back tomorrow to get the other $200. If they do not pay tomorrow, what are my rights, and how and where do I get an eviction form?
We live in Arkansas!

How do you evict someone from a rental property in the State of Florida?

I own a house in Florida. I have a renter who has not paid me rent in 6 months. I will not be sueing him for back rent mainly because I will probably not get it. So I have started the eviction process. We have served the 5 day notice etc. Now we are down to the 24 hour notice part. I believe now he will be thrown out by the Sheriff. Last week he went over to my mom’s house(who is handling things for me because I am away) He tried to ask for more time, claiming that he will file some sort of letter with the Clerk of Courts asking for 60 more days. He has 2 little kids and uses them as ammo to live for free. My mom went over there to see if he has left as he was repeatedly asked to do. My mom said he was out cutting the grass, kids playing in the yard, even
though (according to what we know) he will be physically removed from the property by Tuesday, it is now Saturday. Is there something up his sleave? Specifically, could he just come back a squat after we throw him out?? Any an all info on this would be great.

Please help me!!! Eviction question?

Okay, so I live in this house under a month-to-month agreement that is signed by me, and by me only. I had two females move in (it’s a 3BR house) on the 15th of January and they’ve caused hell! They’ve touched, thrown out, and used my personal things (including drinking a $50 non-replaceable bottle of wine), brought a dog into the house when I made it adament that the landlords didn’t allow pets, and I’ve been fed up! I want to evict them but I know they pay their rent to the landlords directly, and not to me, which, I realize, puts a damper in what rights I have to kick them out. So what can I do? And where can I find 30-day Notice of Termination of Tenancy forms? Thanks so much! Appreciate it!
P.S. I live in California in a city with no rent-control ordinances in effect.
