Suing the Buyer's for Security Deposit -Now what??

[Josi Colley]

We sold our house with a 30 day rent back and $1500 security deposit. Now the buyer's are making false claims and seeking to keep our security deposit. We took them to small claims court with 3 subpoenaed witnesses (friend, neighbor, house cleaner) all ready to testify on our behalf that we left the house per the contract. They sent their attorney to pull it out of small claims court and move it to General District Court where they can have representation. This was a scare tactic to get us to settle. They know they don't have a case against us if it goes in front of a judge. We're pretty sure their attorney is a family friend and doing this pro bono! So, they're not out of pocket. 

We've called 3 lawyers and would have to pay $300-400 just to get advice and see if it's worth pursuing. I'm reluctant to go to just any lawyer for advice, and especially at that rate. I at least want to know they have experience with this. 

Any advice? recommendations?
