You can issue legal notice to your parents that on account of their abusive behaviour you are disowning them and do not want to maintain any contact with them 

2) also issue public notice in this regard 

Dear Sir,

Just issue a newspaper publication accordingly and issue a legal notice and disown them. Nothing is wrong, many parents after attaining certain age they behave in such a manner which cannot be tolerated by the children and grand children.  It is a hard fact.

Hello,

As per the provisions of maintenance of welfare and parents and senior citizens act, 2007, you are required to take care of prents and not doing so the parents might file a case before appropriate authority.

there is no specific provision for overcoming the effect of the same, still you may send them a notice for disowning them and make a publication in the newspaper so that you have a valid defense to take in case they approach any authority.

regards

You can give a public notice in newspaper If you desire so

Contact a local lawyer for issue of legal notice and for issue of public notice 

You try to convince the parents or either relatives and ask them to forgive for their sins. 

You better keep good relationship with all relatives they will be fine with.

Disowning the parents is not solution because senior citizens act are with them.

See there is no as such procedure for disowning parents if parents senior citizen they can ask maintenance under Senior citizen and welfare act what you can do is you can make a newspaper publication of same and can stay separately.

Further can also give a legal notice to them stating that you do not want to maintain any relationship and want any share in there property.

Legally Not Possible.

Parents are more important than God and third persons. Why ? Because God gives us life with both happy and sad moments but our parents always try to give us only happy life. Try to convince your parents with your knowledge peacefully.

There is no such law for disowing biological parents but yes jointly alongwith your relatives you can file domestic violence case against them alongwith your wife. There is a law which states parents should stop interfering in their children's lives after marriage.

There is nothing like disowning the parents and you have certain responsibility to be fulfilled legally are your parents which is provided under maintenance of parents and senior citizen act 2007 and you are responsible for taking care of your old age parents so there is nothing like disowning the parents and your decision in this regard  can be legally challenged.

It is immaterial that what your relatives think about your parents weather this is more important that how you keep your parents in their old age.

If you do it willingly voluntarily then this is fine otherwise this can be forced on you legally.

In your question you have not informed about the age of your parents

I presume by now many would have replied to your question about disowning. Also, googling the topic will give you good result.

So I would like to add to whatever others have already told you. By disowning, you can alienate them from your property etc. But when it comes to care giving and other old age stuff, you are still liable and duty bound.

I don't see any reason to disown them apart from alienating them from your property etc. which you can very well do it via will. But then it's your decision.

1. As per the information mentioned in the present query, make sit clear that you have made up your mind to disown your parents due their unchanged bad behavior since years.
2. Firsty you should publish an article (short one) in the local as well as in the national newspaper.
3. Then after 15 days of it, send a copy of the same plus a notice to them.
4. Once you are done with it, legally you have disown them.

Dear client.. I understand Ur concern.. I never suggest u go and again adjust with Ur parents.. 

Yes definitely u can live separate, 

Don't keep much interaction with them .. 

What I m suggesting u is just keep them away from Ur life.. now it self..u r going legally and going to serve a notice to them .. then 

1) whatever property Ur father is having u may loose Ur shear

2) when u serve the notice.. the legal battle will start between u and Ur parents.. then they may suit against u .. for maintenance.. / not taking care of parents ect .. so my suggestion is instead of going legal.. u just move out  with ur family and start staying separately.. don't attend every call from them just keep distance.. 

Dear Querist

there is a procedure to disown or severe relations with anybody/relative, as per your information you want to disown your parents from you and your family.

published the same(your intention) in two Leading News papers one should be national and one should be Local.

issue a notice to them through your counsel regarding the same.

that's it.

if you want to to further then you may also file a civil suit for declaration against them before civil court.

Feel free to Call

Legally there is no provision in law for any such act called disowning the relationship.

Except for husband and wife relationship , which comes after birth, no other relationship can be disowned or discarded.

They will remain related forever whether you like it or not.

If you cannot tolerate them anynmore, better you leave their  company and stay very far from them, disconnect all your contacts with them namely, block their numbers in telephone, other siocial media netwroks, dont entertain them even through friends and relatives, keep away from any type of sentiments connected to them

How to proceed with both of your suggestion

In my opinion, you may just issue a public notice that since you have left the company of your parents for their ill-mannered behavior, attitude and activies, you cannot be held responsbile for any of their acts which might have harmed them .
