I have mailed the check excuse

[Jay P.]

Hi All, 

I have a court hearing for judgement on May 3rd.

The tenant and I agreed at the end of March that all rent from Feb to Current would be paid by April 15th. This was a court order agreement. 

So far, I received a check TODAY (May 1 2017) for 50% of the rent he owed for Feb. 

He is emailing my attorney and myself saying how he has mailed out the checks for the previous months and that they must be lost in the mail or that I am not cashing them. 

He did send this one check I received "certified" but nothing else was certified. 

Does this type of excuse work in Court to delay this judgement further? As I am guessing his end goal is to delay and get as long as he can for free. 

Thanks
