I agree with you there Virtues.
If your uncomfortable then pack your stuff and go. If not don't hold up your rent, it will only make matters worse.
Legally a bailiff can seize stock and items relating to a business to repay the debt owed as per the warrant/court order. A bailiff cannot force to enter the property but can go through a back door/window etc and can if required use force once in, so be cautious if he comes back and it's not sorted. If he takes your property you'll have to prove it is yours and try and get it back before it's sold on (they keep the property for a minimum of 7 days) The salon owner will have known about this for ages and must be at least 2 months behind for a warrant to be executed - If not more as she has probably tried to resolve it or made partial payments. If someone is buying it off the owner this will not be completed in 3 weeks even if she is a cash buyer - there's valuations etc that will have to take place and if a commercial mortgage is required that will take even longer. But selling it has not resolved the current debt, so he will still probably come back unless she either clears the debt or rectifies the situation by making a payment plan until the property sells.
I worked in an estate agents, also was a debt collector for mortgage arrears for 2 years - arrears, bailiffs and court orders are my thing
Hope it goes okay x
