Right now you can be legally asked to take a drug test before doing almost anything. I expect anyone who extends credit to people to do it before long.
Not legally
Legally, they're not allowed. Call the ICE or cops, see what they can do.
The lien will have to be paid before the sale can go through. Possibly the amount of the lien could come out of the sale proceeds, but you would have to check with the title company to see if this is legally possible.
Signing a lease agreement form is up to the person renting an apartment, not the renter. Before signing, a potential renter should understand the terms of the agreement. A good lease offers pretection to both parties.
You could look for someone to sublease your apartment or ask if the landlord would be willing to let you break the lease early with a penalty fee. Another option could be to negotiate with your landlord to find a mutually agreeable solution.
A notary has to follow the rules required for their jurisdiction. In almost all of them, you have to verify the identity of the person signing in front of you. Then you can legally notarize their signature.
This means the apartment is allowing you to still live there (perhaps you settled and paid the arrears but not before the Landlord obtained a Judgment or writ of execution against you but chose not to kick you out)
Given the prevalence of satellite dishes these days, many apartment complexes will allow for them. However, if having a satellite dish is important to you, be sure to check with your potential landlord before signing a lease.
tell him to get out, get legally separated and call the cops.
Before your apartment can be shown to a potential tenant it must be vacant. A landlord only the right to be in your apartment for routine or emergency maintenance, the former with proper notice of at least one day. Until you are legally evicted from their apartment, it remains your home.
It is not illegal but it is up to the landlord or owner of the complex to decide whether or not they want to allow this. Check with them before doing any work. Some are very anal about oil spills and whatnot.
I am going out on a limb here you must have a witness present along with a Judge before signing documents legally and of course legal counsel by all means...
