Hi, I'm in an area where leasehold houses are very common. My ground rent is £3.50 per year. Solicitors can't track down who holds the freehold and ground rent hasn't been collected in years. Buyers solicitors have asked me to pay for 6 years worth of lease (£21 so fine) but also to get an indemnity insurance policy which comes in at £147 which seems extortionate. I've said no but will I have to?
