TR1 form

Hello,
I sold a property in October last year.  I have been contacted this week to say that the TR1 form wasn't filed, apparently it was lost in the post.  Have been asked to send the form again (to our buyers solicitor).  I am fine with doing this, but is there anything to be aware of? 
Thanks for any advice, 

Hello - nothing other than perhaps keeping a copy for your own records

Thank you
