Thank you for contacting Just Answer.
Answer: You can sue for, and ask for, whatever you want in Small Claims Court, but the judge may not have the authority to give you a financial award for everything you request. Given your situation and frustration, I would DEFINITELY take this to Small Claims Court. When you file your request/complaint, be sure to request reimbursement for the costs of filing your complaint and for service of process.
In Texas, there is limited online information about SCC (but I see the JustAnswer ad on the same page). Try here: http://www.consumeraffairs.com/consumerism/small_tx.html
When you file your complaint, you can attach exhibits, such as a copy of the promissory note. Only use copies, and number them in order, so you can easily refer to them. Bring the originals with you to court in case there's an argument about the copies.
Good luck to you, and don't hesitate to write back.
I'm happy to answer follow-up questions. If you have none, please
"ACCEPT" my answer.
There can sometimes be a delay of an hour or more in between my followup answers because I may be helping other customers, conducting legal research, or taking a break. If we're writing late in the evening, I may need to get some sleep and resume helping you the following morning.
