Bromhead - if you want me to fire you over the house rules & agreement I drew up for my lodgers let me know. E-mail in trust.
Regardless of how good a friend they are set some ground rules for cleanliness, noise, parking, pet peeves etc. Take a deposit too.
More likely than not whatever you draw up won't hold up in a court however chances are the other party doesn't know that and isn't prepared to shell out to find out if it does!
It's all just a precaution really but you'll kick yourself if you didn't do it if something kicks off.
Thank you Benny that would be great, I'll e-mail you in trust now
