I have a lady who owes $170 for lawn care and shes made it clear that she's going to do what ever she can to not pay it. She is not on a contract or a service agreement. (my mistake) But today when I went to collect for the fith time I wrote up an agreement saying she was going to pay me the remaining balance and her sign it and had a witness sign it. Will this hold up in sm claims court. Or can I put a lien one her house. She is moving soon so I need to act fast. Any advice would help.
