Register Website in another country

Hi Chaps,

Quick question, I have a website which is registered in the UK: www.domain-site.co.uk.

I’m planning on having the site translated into German and then submitting the site through google.de (www.domain-site.co.uk/de/ or www.domain-site.de).

Is this possible, and are there any drawbacks or anything that I should be aware of, i.e., is this general good practice?

Many thanks

Samuel
