name and surname both changed after marriage

 HI . AS PER MY KNOWLEDGE THE FIRST STEP IS TO MAKE AN AFFIAVIT TO THIS EFFECT IN FRONT OF AN OATH COMM. AND THEN GET IT PUBLISHED IN ANY OF THE NEWSPAPER OF UR AREA HAVING A GODD NUMBER OF CIRCULATION. THEN WHENEVER NEEDED U HAVE TO ATTACH BOTH THE PHOTOSTST COPIES OF THE AFFIDAVIT AND THE NEWS ITEM. THE NAME CHANGE WILL STAND VALID. 

the official GEZZET/ EX-ORDINARY gazzet of state must notify the change notification officialy through Government.

This is a common practice adopted by most married women. In such a case, the logical thing to do would be the marriage registration.
   Legally, there are two ways to go for the name change. One is to submit a joint notarised affidavit or a copy of the official government gazette mentioning your new name. Then your husband and you would need to make a joint notarised affidavit on stamp paper, signed by a magistrate or a notary. The affidavit also carries a joint photograph of your husband and you. This notarised affidavit, along with your marriage certificate, is enough to change your name at the bank, on your passport, on the Permanent Account Number (PAN) and driving licence.
   Then the second step would be to apply for a new passport. Then there would be a deletion of your name from the old ration card and its addition to the new one. Similarly, you have to apply for a new PAN card with the old number. This would be to avoid duplication of PAN. Only after you complete the whole procedure, should you proceed with purchase of assets, joint holdings and fair distribution of expenses.

Ther eis no need to follow any procedure for a lady to change surname on marrriage. Howevere for chang eof name the procedure is to be followed.
