You can apply to the information officer of the concerned authority where you were born to issue a copy of your birth certificate.

Fill in the RTI application form in detail and send it to the said officer through Registered AD Post and request for sending the same to you through post and mention that you are ready to pay for additional charges that may be required.

In my opinion open the RTI Act on your net and go through the provisions of the same for absolute knowledge and information.

For this you should have the knowledge of the date of registration and the registration no. Of your entry of birth and other particulars.

If you are not aware of this information then you have no option except to personally visit the concerned office in Karnataka and move an application under RTI Act for inspection of the relevant record of your year of birth and after inspecting the said record you will have all the knowledge for filling in the application for obtaining your birth certificate .apply for issue of more than one copy as you may need as extra originals come in use as it would have in your present case.

Yes you can apply for birth certificate in the office of sub registrar birth and death by providing copy of BC in the state where your wife was born.
