Dispute over money, might end up in a lawsuit?

Question

bought something worth $4000 plus, everything is verbal. but text messages are kept. agreed initially to pay in instalments but later the other party decided to demand for full amount suddenly. any chances of lawsuit?

Answer 1

They could sue you but you can't get blood from a turnip.  If it was agreed to pay in installments and you have text messages to that effect, there really isn't much chance that they are going to win and get the full amount.
