Can you register as limited liability without a partner?

Why do you think sole proprietorshio is not safe? It has just few demerits like non corporate  but if you have businesses policy u are welcomed everywhere 

There are less regulation for sole proprietor. It more beneficial to go solo... Stay single stay happy

in the software world it is common for big corporations to bully small entrepreneurs by taking them to court over frivolous matters which eventually fall in favour of the small entrepreneur. It is also possible that a company makes an honest mistake that results in a system glitch and big losses. in such cases, the proprietor should not have to fear losing his personal assets and future.

That is why limited liability is important to have even if the intention is to conduct honest business.

to give an example, lets say I start a consulting business as sole proprietor and win a contract with a big company. as per the contract, if the software system I build for them causes them downtime or losses I would have to compensate them for the losses. Then I build the system with my honest intentions and hard work but the worst happens and it has a bug which no one noticed. now my company is expected to compensate for all the losses caused. now I might be forced to give up all my personal assets (even the ones I had before I started the company)

Your requirement is genuine but there is no other option for a single person other than proprietorship and one person company.

but even one person company requires a nominee compulsorily. the nominee is the one who would continue the business if the director is unable to run the business. so if there is no one to put as nominee then even one person company is not an option correct?
