Hi Eduardo I have now reviewed the Lease extension.
It is good to see that the Lease is to be extended for such a long time- normally a Lease extension normally only grants an additional 90 years to the existing Lease! The only major thing I would say is that it implies that you are not paying any money for this Lease extension. Is that correct?
I confirm that the rent is a peppercorn which means in effect that it is zero.
There is one item that needs to be amended- the definition of your current Lease is referred to "Existing Lease" but in line 3 of the definition of Incorporated terms at the bottom of page 5, it refers to it as "the Lease". So, the Solicitor needs to delete "the Lease" and put "Existing Lease" in its place.
Also, in the same paragraph (bottom of page 5) there are too many brackets and some of them need to be removed- your Solicitor will make sure this happens as it is just a typographical error.
Apart from the above, I confirm that the document is in pretty standard format and there are no onerous or unusual provisions and is therefore in your best interests.
I hope this helps and if so, I would be grateful if you could rate my answer with 3-5 stars.
Kind Regards Al
