I'm confused if they are self employed what would you want in the contract to make it so complex? Being self employed (as defined by HM revenue and customs) means they can "decide what work to do, how and when to do the work" so what are you trying to make sure they do? is it just to make sure they pay you what you are owed for the space? :hug:
Quote "The main elements of a valid contract of service (employment), or a contract for services (self-employment), are:
the intention to enter into legal relations
an offer (usually of work) and its acceptance (an agreement)
consideration (for example, in return for performing work the worker receives payment)."
If they choose their work hours, pay for their own equipment, own their clients, pay their own tax and national insurance they are self employed.
If you pay them and they work when you want them to on your clients and you deduct their national insurance and tax from their pay then they are employed.

What's confusing you? :hug:
It says on the website that "Our Status Inspectors may be able to express an opinion on employment status" maybe you should contact them before working out what type of contract you need before contacting your solicitor to get it right.
