Barn Manager SOS
My friend and I are moving our two geldings to a new farm. We gave our current barn manager 30 days notice, and it seemed very amicable, until yesterday. She left us bills dating back to December 2009 for "extras" (blanketing, bell boot changes, etc.). Some of the bills listed we had already paid, and some we have invoices for that were different (lesser) amounts than what she is charging us. Many we had never seen.
The last time that she handed us a six-month update for our "extras" was in April 2011 - we understood that we were paid up until that date.
We only had a verbal agreement for boarding where we are - no contract signed. How much legal responsibility do we have to pay for all of these "extras" (mine amounted to a little over $500)?
