Dear sir, 

Yes, the completion certificate can be obtained without mutation and new names since it shows that the building has complied with the safety norms. Since your father died intestate, it is recommended to get the  surviving member certificate.

Hopes that solves your query. 

you can contact me for consultation, if any.

What is the need of CC ?

It is issued when construction plan is sanctioned by authority and sanction needs for construction on above 350sq mtr land.

Dose not require mutation, 

If the said municipal authority accepts your application for the same without mutation then you can but generally they will ask for the same

Yes you have to apply for mutation of property before applying for completion certificate or you can apply for certificate as legal representative of your father by taking authority letter from other legal heirs of father. 

Dear Sir,

Obtaining Occupancy Certificate and Completion certificate can be mandatory under respective State laws.  As per these state laws, one cannot legally move into a building unless the developer gets an occupancy certificate from the respective local administrative or civic bodies. The corporation or municipality can ask the apartment owners to leave such illegally occupied flats or impose heavy penalties in the name of ‘regularization’.

Upon the completion of the building construction, the builder or the developer of the apartment has to apply for the ‘building completion certificate’ with the local authorities (like BDA or BBMP in Bangalore or PMC in Pune).

If the building construction is completed as per the building approval plan and if it also meets other building standards like distance from road, height of the building, if rain water harvesting system is in place etc., the civic authorities will issue CC.

1. As per the information mentioned in the present query, makes it clear that you want to get the completion certificate but after making some new addition to the details.
2. See, you all are the legal heirs and will have to get the succession certificate to get the property equally registered in your individual names, but that can be done later also.
3. Now, you should get the Succession certificate from the court of law and then proceed to get the completion certificate on your names.

In what capacity can you move such an application?

The property is on the dead person's name and a dead person  cannot move an application seeking CC from the authorities.

Hence it would be advisable to transfer the property on the names of his legal heirs and then apply for any such thing which would be proper and would find no legal hassle.

you may enquire about it with the MCD authorities by visiting their office in person instead of getting any misguiding replies from such forums.
