You can get a one and the same name affidavit duly notarised in India stating that your name Rakesh and Rakesh Upendra Patil are one and the same.

If you are likely to use this document in a foreign country, you may get this document apostilled by Ministry of Home affairs.

Once apostilled, this affidavit becomes legally valid internationally.

If you are currently in Germany, you can directly execute the same affidavit at the Indian Embassy or Consulate there.

They’ll attest the declaration, and you can use it for your child’s VISA or passport application and for any foreign authority verifying your name identity.

This is often simpler than doing it in India because the embassy’s attestation automatically carries international validity.

You cab execute an affidavit on Rs 100 stamp paper that both are one and same  person 

get affidavit attested before Indian consulate if you are staying abroad 

If you are in India get affidavit duly notarised 

In India you can have a notarised affidavit for the same. In other countries you need to check the local law of specific nation for the same

Name Identity Affidavit (Affidavit of One and the Same Person)

This is the simplest and most widely accepted method.

Steps:

1. Draft an affidavit on non-judicial stamp paper (₹100 or ₹200) declaring something like:

> “I, RAKESH, holder of Indian Passport No. ________, presently residing at ________, do hereby solemnly affirm that my name appears as ‘RAKESH’ in my Indian Passport and as ‘RAKESH UPENDRA PATIL’ in my daughter’s birth certificate. Both names refer to one and the same person, i.e., myself.”

2. Get it notarized by a Notary Public in India (or at the Indian Embassy/Consulate in Germany, if you’re abroad).

3. Apostille or Attestation (for overseas use):

If the document will be used in Germany or another Hague Convention country, get it apostilled by the Ministry of External Affairs (MEA), India.

If it’s a non-Hague country, then get consular attestation through the embassy of that country.

If your passport shows your name simply as “RAKESH,” but your daughter’s birth certificate mentions “RAKESH UPENDRA PATIL,” you can easily prove both names refer to the same person without changing any documents right now. The best way to do this is to make a sworn affidavit or declaration of name variation, stating clearly that both names belong to one and the same person. Once the affidavit is notarised and properly attested or apostilled, it becomes legally valid both in India and overseas, including Germany.

You can prepare a short affidavit on plain paper or stamp paper (depending on where you execute it), mentioning:
“I, RAKESH, son of [father’s name], presently residing at [address in Germany], hereby declare that I am the same person referred to as ‘RAKESH UPENDRA PATIL’ in my daughter’s birth certificate issued on [date] at [place]. Both names — ‘RAKESH’ and ‘RAKESH UPENDRA PATIL’ — refer to one and the same person (myself). This declaration is made for visa and official purposes.”

Attach copies of your passport (showing “RAKESH”) and your daughter’s birth certificate (showing “RAKESH UPENDRA PATIL”). Then have the affidavit notarised by a Notary Public or Magistrate.

If you are in Germany, you can do this before a German notary (Notar) and then get it apostilled by the local German authority — Germany is a signatory to the Hague Apostille Convention, and such a document will be recognised internationally.

If you are currently in India, execute the affidavit before a Notary Public in India and then have it attested by the Ministry of External Affairs (MEA) and, if required, by the German Embassy or Consulate in India.

This affidavit, once duly attested or apostilled, will serve as valid proof that both names refer to the same individual. It is commonly accepted by foreign embassies, visa offices, and other government bodies. There is no need to alter your existing documents right now — you can rely on this affidavit whenever you need to show identity consistency between “RAKESH” and “RAKESH UPENDRA PATIL.”
