Here are several things you need to know:
1. Read your lease. You may be in violation of your lease agreement if you don't pay the full amount.
2. You can pay partial rent, but you just might still receive an eviction notice. So do talk with your landlord directly and also put your request in writing too. Ask your landlord to prepare a receipt for your partial payment.
3. If your landlord agrees that you can pay partial rent, you will need the following in writing: how much you paid, how much you still owe, late fee, the rest of the rent owed, when those payments are due, and also an agreement that the landlord will not evict you if you pay the remaining rent due on the specified date.
4. Be sure you and landlord sign all agreements. This will be used in court if you should not meet the agreement.
Seek legal counseling if you suspect your rights are being violated during this process.
