1. “My father brought a flat for me 2006 and it is registered in my name” that makes the flat ancestral in which  all descendants of father  will have share. The  deed you singed with brother is of not any help unless it is registered.
2. You can deny them a share only if it can be proved that the full consideration for the  flat is paid by you and only as respect to him, you allowed to appear him on sale deed as purchaser.

Your siblings can take the plea that Flat was purchased by your father in your name for the benefit of joint family, and they have equal share in thesaid flat

they can seek an injunction restraining you from selling the flat

It is in your interest to give your siblings share in the flat 

litigation is a long drawn and an expensive proposition

An out of court settlement with your siblings is the best option

your siblings can win the court case 

The property was purchased by your father on your name by a registered sale deed, hence it becomes your own and absolute property.

In fact you were not even a minor by age at that time hence it cannot be claimed as a gift also.

There's no evidence to prove that your father funded for the purchase of this property.

Besides it can be proved through your employment details that owing to your employment at various places you permitted your parents and siblings to live in the property till you returned.

The indemnity bond you obtained from your brother while financially helping him shows that you helped him at the time of crisis and as a return you have asked him to not to harass you by claiming any share in your share out of your father's property or your own property.

All these clearly prove that this property belongs exclusively to you alone hence any claim made by your siblings is not legally maintainable.

You can challenge them properly in court of law.

You have rented out the property to tenants as a landlord hence this establishes your clear and marketable title over the property.

Your brothers' s claim based on the undertaking with another brother is not maintainable, they cannot claim any rights in your property on that basis hence you just don't worry about it.

If you want to sell the property you first file a caveat petition against your siblings to prevent them from obtaining an exparte injunction order against you.

Based on the information you’ve shared, the situation involves several legal considerations. Let me break it down for you step by step, highlighting the legal position and options you have to defend your ownership over the flat:

1. Ownership of the Flat

• Since the flat is registered in your name, you are its legal owner as per the Registration Act, 1908. Registration of property confers conclusive ownership, and courts presume the person in whose name the property is registered as the owner.
• Even if your father financed the flat, it does not automatically make him or your siblings the owner unless there is documentary evidence of a trust or benami transaction. The Benami Transactions (Prohibition) Act, 1988(and its amendment in 2016) prohibits property being held in someone else’s name for the benefit of another unless explicitly declared as such in writing. If your father did not declare this as a benami property, your siblings have no claim on it.

2. Gifting Aspect

• Although you lack formal documentation showing that your father "gifted" the flat to you, the fact that the property is registered in your name strongly supports your claim. In the absence of any document or evidence suggesting otherwise, the presumption of ownership lies in your favor.

3. Your Siblings' Claims

• Cheques Allegedly Showing Payment by Your Father: These cheques, if produced, only prove that your father paid for the flat, not that he retained ownership. Given that the flat was registered in your name, the payments might simply indicate that it was a gift or financial assistance for your benefit.
• Deed Signed with Your Other Sibling: This deed strengthens your case because it explicitly mentions that your flat was included as your property, which your sibling agreed not to claim. If your other siblings are citing this deed, it further acknowledges that the flat is yours.

4. Legal Position of Your Siblings

• If your siblings claim that the flat indirectly belonged to your father, they must provide clear and convincing evidence to prove:

1. That the flat was purchased by your father in a fiduciary capacity for himself and not gifted to you.
2. That the payments made by your father established his ownership of the flat and not just financial support to you.

5. Steps to Protect Your Ownership

Here’s what you should do to strengthen your case:

• Obtain Certified Copies of Sale Deed and Registration Documents: These will be the most critical pieces of evidence to prove your ownership.
• Gather Evidence Supporting Your Ownership: Look for any communications, emails, or statements that show the flat was intended for you.
• Challenge Their Claims Under Benami Laws: If your siblings claim that the flat was a benami property of your father, you can counter it under the Benami Transactions (Prohibition) Act. The burden of proof will be on them.
• Highlight Their Motivations: If this appears to be an extortion attempt, you can argue that they are acting in bad faith to harass you or extort money.

6. Legal Strategy

• Issue a Legal Notice: Engage a lawyer to send a strong legal notice to your siblings rejecting their claims and warning them of consequences for harassing you.
• File a Declaratory Suit: If the harassment continues, you can file a declaratory suit under the Specific Relief Act, 1963, seeking a court declaration that you are the sole and absolute owner of the flat.
• Injunction to Prevent Interference: You can also seek an injunction restraining your siblings from interfering with your possession or filing frivolous claims.

7. Court Timelines

While courts aim for swift justice, property disputes can take time, depending on the jurisdiction and complexity of the case. However, your case has a strong foundation, and if you present all the necessary documentation, courts are likely to decide in your favor.

Next Steps

If you decide to proceed, I can assist with:

1. Drafting a legal notice to your siblings rejecting their claims.
2. Preparing documents for filing a declaratory suit or injunction if needed.
3. Reviewing and responding to any legal actions initiated by your siblings.

This is a case where the law is on your side, but proper documentation and legal representation will be crucial. Let me know how you’d like to proceed.

1. There is no denial of “My father brought a flat for me 2006 and it is registred in my name”. That can be treated as your admission of ancestral character of property. Literal interpretation of "property of my father" aligns with the meaning given by your siblings. "property of my father" is property that belonged to father, after demise of father  it becomes ancestral in the  hand of all his legal heirs. If the  meaning of a text is plain, effect must be given to it irrespective of consequences, that is the  cardinal rule of interpretation of instruments.

2.      " and the property of my father" can be given a different meaning. "property of my father" points to other property and not the  flat in question. Hence, said sibling relinquished his right  in the flat as well as other property, if there is any.

The claim made on the basis of Hindu succession act including the amended act is not maintainable. 

They don't have any rights or reason to claim any share in your self acquired property. 

This is your self acquired property and not joint family property hence nobody can claim any share in this property. 

The letter obtained from your brother that he cannot claim any share in future is also not any authority that your siblings are vouching upon now. 

Giving money to your sibling at the time of his need and obtaining an acknowledgement for the money given to him in no way can pave way for their absurd claim. 

You don't have to budge to any pressure. 

Let them go to court,  you can challenge them properly 

They will fighting a losing legal battle because no case is tenable. 

Your act of paying your sibling and obtaining the deed does not weaken your legal case. It demonstrates responsible behavior in managing potential disputes, especially given your sibling's history. Courts will recognize that this was done as a precautionary measure and not as an acknowledgment of shared ownership.

By focusing on the registered ownership of the flat and the lack of any evidence to support your siblings' claims, you remain in a strong position. Let me know if you need assistance in drafting a detailed legal explanation for this or preparing further arguments.

It is not ancestral property 

2)?property was bought in your name by your father for benefit of joint family 

3) you did not have any funds to purchase property 

4) Sale consideration was paid from your father bank account 

5) hence arrive at an amicable settlement 

Sir,

1. I am not discussing law here; I am just giving opinion based on established law.
2. There are any number of judgments by SC where it is laid down that a joint/ancestral property may be purchased in the name of any family member including females.
3. Hindu succession law is not yet fully codified, it is based on shartras and conventions. Right from 1900 up to 2024 the above proposition is upheld by SC and High Courts.
4. Execution of relinquishment deed by one sharer is admission of ancestral character of property and sharers not signing can claim there shares. The rule is,  exclusion of one is inclusion of another.
