How to get access to the husband bank account after his death

I have a question for a lady who is one of my relatives here in Sharjah. Unfortunately, her husband died in Pakistan while she was here in Sharjah along with her 3 kids.

Now she wants to get/transfer her husband's bank account to some Dubai bank to her name or withdraw money. As I understand from previous posts, these are the steps she needs to follow:

1- Get death certificate from Pakistan. Should it be attested from Islamabad UAE embassy or can it be attested in the UAE itself?

2- Get a Legal Heir Certificate from Dubai courts as there is no WILL made by her husband. Is the death certificate only required to apply for this certificate?

3- Should the above 2 documents be presented to the bank to get the account access?

Please let me know if my understanding is correct. It will be a great help if you could mention complete details in case an extra step or information are required.

Thanks & Regards,
