Byweekly non pay/info

[Al Smith]

I am in Nashville tn an have a question on eviction filing an late rent.I have a tenant who is on a 1 yr lease with it set up to pay every 2 weeks.She again is late, last Oct i gave a 14day pay or quit so this is the 2nd , actually 3rd , time shes not paid.I gave a 7day notice to pay or quit on due date .What will i need to do if on the 7th day[ also day the 2nd payment is due] she only pays that past due  an not both past an current? Do you have to give another grace period as with 1st missed payment?

An if i accept the 1st of 2 will that prevent any eviction filings ..

If i wish to file eviction will i have to wait till next mo if  she pays  the late  Jan payment, after the warningletter. ,though 2nd is not yet paid an the grace period hasnt passed on 2nd payment.I know  accepting partial payments can prevent eviction but wasnt sure if its the same on byweekly payments.

Also  oct late fee unpaid..

Any information is appreciated.
