Settlement between my father

You don't need to do any thing. If your parents don't want to give you any thing they have to do what they are expecting from you. In life time any way no one claim share.

Except for inheritance property. I'm not sure what forms you need but any judgment against you could attach to property your parents inherited, unless proven beforehand that you have no interest (such as the agreement you mentioned)

Hello Jayachandran,

I assume that your problem is still open and hence the reply.

My suggestion is to simply ask your parents to have the necessary documentation prepared. The final draft can be shared with you and  you will sign the finalized document. At max you can offer to pay for the expenses.

This way you save most of the iterations required as your parents would know what all they wish to include.

Cheers and be happy.

As you yourself are telling that you want to relinquish the property rights, if you have any on the property, simply write it on a piece of paper and give it to them.  If they are not satisfied, then let them draft a one for you.
