Dear Client,

Through Govt. gazette, you will need to submit proof of Divorce/2nd marriage certificate but dissolution of marriage do not effects the right of child from his father.

So, Adoption deed is advisable, this way, you will become first class legal heir of ur new father and ties with old family will cease except marriage in blood relation.

Change of surname and in documents may possible only after declaration via official gazette and on the basis of adoption deed, it may process.

You are an adult hence it will not legally possible for your step father to adopt you.

Moreover ther was no legal divorce between your mother and your biological father,. hence your mother cannot give you in adoption to your stepfather without the consent of your biological father.

You can add your stepfather's name by following the procedure for change of name and cannot officially claim that he is your father on the basis of the changed name.

You may get the same changed by means of an affidavit and subsequent publication in the newspaper.

Though the name in the ID's can be changed but it will be impossible to get the name changed in the educational certificates.

Regards

It is just a change of your name and it will not indicate the surname or first name or the last name.

The existing structure of your name shall be changed as per your dsire for the name to appear, through gazette publication.

you are at liberty to change your surname to that of your step father through gazette notification and publication in 2 local newspapers

On what substance, authorities will order gazette to change ur last name. Even if ur mother divorced, ur ties with ur father do not cease.

may apply/try to authorities to change ur name with new father`s name on the basis of marriage registration annexed with affidavit./bond that u r willing to end all ur ties n inheritance right from ur biological father ( if needed) and also NOC of ur new father that he has no objection to adopt ur name.

Last name are acquired from father and for any change in the surname/case/religion, due process of law is to be followed except first name.

Without adoption procedure nothing can go ahead. Can a tree grow without a seed or root.

Yes you may change your name any time there is no legal impediment with regard to the same.
