//When you say "Much depends on the evidence of what was done/said/what you agreed and the whole course of dealings between you." what do you mean by this? there wasn't really much said if I remember rightly,//
I mean exactly what I say. If nothing was discussed or agreed the Court will look at what was inferred by the course of dealings between you. It would be wrong of me to go into too much detail (I wouldn't want to cloud your evidence) and best you seek the advice of a solicitor asap.
