Part Payment

Access

my tenant has not provided full months rent now since November 2009. I have had a 'portion' of the rent and the rest has been promised in 7 days time.
My question is whether or not they qualify under the 2 months rent arrears process, which will allow me to serve a 'section 8' if required, or because they have paid a nominal amount have they managed to skip over this clause in the contract.

thanks
