A lot more information would be required before this query can be answered in the correct perspective. As regards capital, it all depends what is the model structure of the start-up, what is the mode of transacting business, who is the target audience/ customer, how much capital is required, what are the current assets and liabilities of the start-up, etc.
In the similar fashion, the legal process depends entirely on what the business model is. For example, if you are selling something, then you would require several tax registrations, etc. Further, if you are running your business from a particular establishment, you might require several clearances and sanctions, etc.
