Dear sir

And if marriage goes wrong then divorce will be the consequence of that. 

NO issue in both situation.

You can marry. there is no legal impediment in the same 

You may get married as per your personal laws 

There are no drawbacks of a live in relation. Just that the wife will not be able to claim her rights as the wife 

This is a marriage between an Indian and a foreign national.

Hence he may have to register his marriage under the provisions of Special marriage Act. 

He can follow the procedures meant for it to make his marriage with her a legally valid marriage. 

It's not an offence to cohabit with her in love in relationship.

However if she claims that you promised to marry her then you may have to look for grounds to defend yourself. 

Dear sir,

You should be able to use the special marriage act to get married in India. 

It would appear that you will need to be resident in India for at least 30 days, and then give a 30 day notice regarding the marriage. Once the notice period has expired, you can get married under the act. The marriage certificates will most likely have to be apostilled to be recognized by Thailand.

Staying longer after registering a marriage is doable, based on your marriage certificate. In that case you would have to convert her permit to live in India.

However, since you want her to stay longer than the 30 days her visa allows, before registering a marriage, then you will need a visa that allows a longer stay. Maybe a longer tourist visa (or even a student visa like you suggest) would solve this problem.

she does not have to surrender her passport or citizenship after marriage. In fact, she will not become an Indian citizen after marriage automatically. The only situation in which she can become an Indian citizen is if she lives in India for a considerably long amount of time.

After marriage, she retains her nationality and passport. If you decide to live in India, she will have to get a residence permit to live in India. After one year of marriage she will be eligible for a PIO card.
