There is nothing to stop you carrying out your own legal work; the restrictions are where you charge for that work. Having said that the area of the extension of leases and the purchase of freeholds under various statutory regimes is peculiarly complicated. Particular forms of notice must be served. Certain time limits must be adhered to. Different types of valuation are applied. It is an area that is very complex and often a lot is at stake and so the help of a lawyer would be advisable in our opinion.
