First of all any purchase on a notarised stamp paper alone is not valid.

An unregistered sale deed is not recognised as valid sale deed as per law.

Moreover the 7/12 records cannot confer title to the owner of the property.

Only a registered sale deed or partition deed or a settlement deed or a gift deed etc., on the name of the vendor shall prove his marketable title to the property.

Just verifying the 7/12 records on his name for the said purchase is nothing but an act of ignorance of law.

Now since you have purchased and having receipt for having paid the consideration amount, you may issue a legal notice to the vendor to execute a registered sale deed in your favor immediately or you will drag him to court for this purpose for which he may be liable for the costs and consequences.

Therefore first ascertain the ownership of the property and then think about constructing a house in it.

Registered sale deed is the primary document on the name of the vendor shall prove his marketable title to the property.An unregistered sale deed is not recognised as valid sale deed as per law.A notorised copy also has no validity .

As per your query ,it is understand at present the title is not transferred.Only the consideration in the property dealing is happened and you got a receipt.

Solution

Send a legal notice for execution of registration to the owner of land with help of a lawyer.

1) for sale of property it had to be by sale deed duly stamped and regd

2) your sale deed was on Rs 100stamp paper and is not registered

3) you don't have clear and marketable title to the property

4) you have not mentioned how property was transferred in name of seller

5) whether sister and step mother had executed gift deed or relinquishment deed for transfer of property in name of seller or it was self acquired property of seller

Hi, the entire transaction is null and void and there is no transfer of property at all.

2. When immovable property has to be transferred it has to be registered before the Sub-Registrar office in your case there is no registration at all so you are not a owner of the property.

7/12 document is not an instrument of title. Anyone can have his name incorporated in the 7/12 certificate but this does not create a title in his favour. Be that as it may, if others are now claiming that they are the owners or co-owners of the property then they are at liberty to file a lawsuit for cancellation of sale deed in the court, which your father can contest on merits. Unless there is an injunction issued by the court you can construct the house on the land.

1) if sister and step mother have executed relinquishment deed in favour of seller then they have no share in property

2) ask seller to execute sale deed in your favour

3) if seller refuses file suit for specific performance

If the seller receive it by relinquishment deed then the person who execute the said deed had lost their right over the property. If a sale deed executed in favour of you by seller then only you can get absolute ownership in that property.

First you take possession over the property. You are bonafide purchaser so burden of proof sifted on the seller to prove that transaction was malafide.

your document is legally valid and you have right to prove your title in the property.

Who executed the relinquishment deed in favor of the vendor?

Whether the relinquishment deed was a registered document?

Whether you were handed over with the original relinquishment registered document at the time executing a registered sale deed in your favor by the vendor?

If the vendor has executed a registered sale deed in your favor, you may not be worried about the claims made by his sister or step mother, let them file a suit claiming partition or anything, you may sail with the vendor,and should strictly instruct him to protect your buying interests in the property or else a criminal complaint for cheating will be lodge against him with the concern police, this will instill fear in him and may cooperate with you for the property dispute litigation.

Anybody can file a case to seek a declaration of his title but he has to prove his title. If the relinquishment deed has been executed by the relatives of the seller with their free consent then they cannot now go back to challenge the deed,
