This article is all about construction contracts in the UK construction industry between the main Client and the main contractor but also mentions sub-contracts between the main contractor and the subcontractors.
Stravelles run a course in Adjudication which aims to allow the student to run their own adjudication as the referring or responding party without paying for legal representation.
We support legal representation in more complex cases but we want to encourage especially smaller companies to feel more confident fighting for their contractual rights.

What is a contract ?
A contract is simply a promise or set of promises from one party to another which the law will enforce.
There are several forms of contract which we are going to identify in this article.
Different types of contract
There are several different types of contract. There are the standard forms of contract published by the organisations mentioned above and these can be purchased as physical or digital copies.
However parties can buy these contracts and then modify them or customise them to their own individual needs.
