We have received a demand on ground rent from a new company which owns by same shareholders of the landlord of our flat. The demand was chasing not only the yearly ground rent of GBP100 (which we paid yearly), and also the difference of inflation amount since the flat was built in 1995 - that is GBP830:mad2:. However we did not own the flat from 2004, we rejected to pay the amount for the period that we did not own the flat. We then wrote to them for dispute. The landlord did not response to us at all and later they sent the demand to our mortgage bank and requested the amount:-x. At the same time, we investigate about the landlord about the new company and find out that the original company (which we used to pay the ground rent) was strike off:???:. The directors of the orginal company bought a new company and request for the ground rent and the additional amount. Unfortunately, the mortgage bank paid the demand and claimed that they did not consider the dispute as a good enought for them not to pay. We then decided not to pay the ground rent anymore until a full explanation from the landlord. However, the landlord did not reply us and reject to send the demand to another address. Recently, we find out the new company is a dormant and plan to strike off again. We have following questions? 1) Is it legal for the landlord to transfer the freehold from one company to another company without notification to the leaseholder of the flat? 2) Can they collect the ground rent for the period that we did not own the flat (obviously it is unreasonable!!!) 3) Can the landlord refuse to send the ground rent demand note to another address? 4) Is it legal for the new company to collect the ground rent (the company is dormant and plan to strike off)? 5) We did not hear anything from the landlord since they sent us the GBP830 demand note on ground rent. What should we do? We are so miserable ... not to know what we should do. We want to sell flat , however, we have no clue whether it would affect our selling.
