There's [a simple contract template](https://stuffandnonsense.co.uk/projects/contract-killer/) going around design and development communities that includes this clause:



> 
> Although the language is simple, the intentions are serious and this contract is a legal document under exclusive jurisdiction of English and Welsh courts.
> 
> 
> 


Regardless of the rest of the template, if a contractor sends this contract to an American client:


* Would the American client refuse to have to potentially deal with non-American courts, in the possibility of a conflict?
* Should the contractor pick just one court (English OR Welsh)? What happens if there's an issue and English and Welsh laws disagree on that specific point?
* Could the contract stipulates that is enforceable under exclusive jurisdiction of American, English and Welsh courts, but that the Welsh one takes precedence?


What is simpler and best for both parties, considering the extreme unlikeliness that such a minor project would end up in court?
