Director's UTR and Company's Capital

[RizKCB]

Can anybody share experience in following matters please?

1) Other than to open a Limited Company and receiving company's UTR number, there is another form to fill in and send to HMRC which is for requesting UTR for company's director. It is Form SA1. Is there any critical role of not getting Director's UTR in time?

2) When opening a company, share capital amount has to be mentioned. In case of Entrepreneur visa, should this amount be mentioned while providing data for company as follow:

i) 25000 for one partner and 25000 for other partner OR
ii) 50000 for single applicant
