Unless your lease and the other leases say that all the leases
must be the same, (in which case all the leases must remain the same) then each
lease can be different and each lease can be varied.
To be honest, there is absolutely no reason why anyone who has no
intention of keeping a pet should change their lease to stop people keeping
pets because it is of no advantage to them. It could have been done as part of
a reciprocal arrangement but that seems extremely unlikely. Indeed, even if it
was done, why limit the number of future buyers that you might get when you
come to sell the property?
If all the leases don't have to be the same, then you do not or
have to agree.
If there has been a deed of variation, it should have been
registered at the land registry but sometimes people are remiss in doing so.
However, if all the rest of the non-pet lovers want to rely on it, they had
better come up with something signed by a previous owner. As this has not
cropped up in 23 years, I think it is unlikely that this ever happened and
therefore what you are asking for is an impossibility I am glad to be able to
With regard to what you put in capitals, the previous paragraph
that I have written applies. Basically it means that if there has been a deed
of variation, the original lease is completely as it stands but subject to the
amendments in the deed.
There is an original lease of 99 years and later lease of 999
years and I assume that neither of them referred to pets. I therefore think
that the variation they are talking about could be the term going from 99 to
It could be that the new lease slipped in a new covenant, not to
keep pets and therefore you need to look at the new lease. If the new lease
doesn't mention it and there is no deed varying it (it seems unlikely), then
the situation is exactly as I have already explained to you.
If there was a covenant in the deeds, or a deed of variation
lurking around, the management company or the freeholder would not be turning a
blind eye. They, along with all the other leaseholders who do not want animals
would be jumping up and down for joy and having a little party and waving
relevant document at you and telling you that you couldn't have pets. I am sure
you take my point.
They obviously have not done that which probably says it all
