Myself and a partner are going to be starting our own business within the next month. It's an online store and we have already been doing a lot of planning.
In order to take the next steps such as setting up the business bank account and copyrighting the brand we need to register as a limited company.
Presently I am still studying at university and work during non term time. I will speak to my employer to make it clear that my comitements to them will not change, and that I will still be able to work that same hours. I am sure they will not have a problem but would they be within their rights to terminate my employement because essentially I would have two jobs?
Also would it be necessary to talk to them before registering as a ltd or can I do it once everything is set up and running?

Any advice will be greatly appreciated.
