Jane (my partner) and I may need to rent out our Wandsworth ground floor flat for a while due to taking a sabbatical. We used a Wandsworth conveyancing firm in 2004 but they have closed and we did not have the foresight to seek any guidance as to whether the lease permits subletting. How do we find out?

A lease dictates relations between the freeholder and you the flat owner; in particular, it will say if subletting is banned, or permitted but only subject to certain caveats. The rule is that if the lease contains no expres ban or restriction, subletting is permitted. Most leases in Wandsworth do not prevent strict prohibition on subletting – such a provision would adversely affect the market value the flat. Instead, there is usually a basic requirement that the owner notifies the freeholder, possibly supplying a copy of the tenancy agreement.

My wife and I purchased a leasehold house in Wandsworth. Conveyancing and Platform Home Loans Ltd mortgage organised. I have received a letter from someone claiming to own the freehold. Attached was a demand for arrears of ground rent dating back to 1991. The conveyancing practitioner in Wandsworth who acted for me is not around.Any advice?

First contact the Land Registry to be sure that the individual purporting to own the freehold is indeed the registered owner of the freehold reversion. It is not necessary to incur the fees of a Wandsworth conveyancing firm to do this as you can do this on the Land Registry website for less than a fiver. You should note that regardless, even if this is the rightful landlord, under the Limitation Act 1980 no more than 6 years of rent can be collected.

I am tempted by the attractive purchase price for a two flats in Wandsworth both have approximately forty five years remaining on the lease term. Will this present a problem?

A lease is a right to use the property for a prescribed time frame. As a lease gets shorter the value of the lease reduces and results in it becoming more costly to acquire a lease extension. For this reason it is advisable to increase the term of the lease. More often than not it is difficulties arise selling premises with a short lease as mortgage companies may be reluctant to lend money on properties of this type. Lease enfranchisement can be a difficult process. We recommend you seek professional assistance from a conveyancer and surveyor with experience in this field

Last month I purchased a leasehold flat in Wandsworth. Do I have any liability for service charges relating to a period prior to completion of my purchase?

Where the service charge has already been demanded from the previous owner and they have not paid you would not usually be personally liable for the arrears. Strange as it may seem, your landlord may still be able to take action to forfeit the lease. A critical element of leasehold conveyancing for your conveyancer to ensure to have an up to date clear service charge receipt before completion of your purchase. If you have a mortgage this is likely to be a requirement of your lender.

If you purchase part way through an accounting year you may be liable for charges not yet demanded even if they relate to a period prior to your purchase. In such circumstances your conveyancer would normally arrange for the seller to set aside some money to cover their part of the period (usually called a service charge retention).

I work for a reputable estate agency in Wandsworth where we have witnessed a number of flat sales put at risk as a result of leases having less than 80 years remaining. I have been given inconsistent advice from local Wandsworth conveyancing firms. Can you clarify whether the vendor of a flat can start the lease extension formalities for the purchaser on completion of the sale?

As long as the seller has owned the lease for at least 2 years it is possible, to serve a Section 42 notice to commence the lease extension process and assign the benefit of the notice to the purchaser. This means that the proposed purchaser can avoid having to wait 2 years for a lease extension. Both sets of lawyers will agree to form of assignment. The assignment has to be done prior to, or simultaneously with completion of the sale.

Alternatively, it may be possible to extend the lease informally by agreement with the landlord either before or after the sale. If you are informally negotiating there are no rules and so you cannot insist on the landlord agreeing to grant an extension or transferring the benefit of an agreement to the buyer.

I own a basement flat in Wandsworth. Given that I can not reach agreement with the freeholder, can the Leasehold valuation Tribunal make a decision on the premium payable for the purchase of the freehold?

in cases where there is a absentee freeholder or where there is disagreement about the premium for a lease extension, under the Leasehold Reform, Housing and Urban Development Act 1993 it is possible to make an application to the First-tier Tribunal (Property Chamber) to arrive at the price.

An example of a Freehold Enfranchisement matter before the tribunal for a Wandsworth residence is 4 Galveston Road in August 2012. The Tribunal determined that the price payable in respect of the purchase of the freehold was £22,650. The Tribunal remited this matter back to the Wandsworth County Court for execution of the freehold Transfer Deed. This case was in relation to 2 flats.

I inherited a 2 bed flat in Wandsworth, conveyancing was carried out in 2001. Can you shed any light on how much the price could be for a 90 year extension to my lease? Similar flats in Wandsworth with a long lease are worth £250,000. The average or mid-range amount of ground rent is £60 invoiced annually. The lease terminates on 21st October 2103

With just 77 years remaining on your lease we estimate the premium for your lease extension to range between £10,500 and £12,000 as well as plus your own and the landlord's "reasonable" professional fees.

The suggested premium range that we have given is a general guide to costs for renewing a lease, but we are not able to provide the actual costs in the absence of detailed investigations. You should not use the figures in tribunal or court proceedings. There may be additional issues that need to be taken into account and you obviously should be as accurate as possible in your negotiations. Please do not take any other action placing reliance on this information without first seeking the advice of a professional.
