If you’ve been contacted by a developer or a land promoter regarding a potential development to your property, you may wish to consider granting an option agreement or a promotion agreement. An option agreement is made between the landowner and the developer, where it is intended that the developer will apply for planning permission and requires an option to buy the property. A land promotion agreement is used where a developer agrees to apply for planning permission and will market the property for sale on the open market once planning permission has been obtained. This is usually in return for a proportion of the net sale proceeds. The law on this is very complex and you will need specialist advice.
