Father's land

First and foremost, be assured all the 9 of you (6 brothers and 3 sisters) have equal share in the entire property.

Your brothers are completely in the wrong. 

As you say that your father had bought the land in question (and not got it from his forefathers), it is not at all ANCESTRAL, as being claimed by your brothers.  So, the year 2005 etc., being cited by your brothers is absolsutely not applicable in your case at all.

Be firm and tell them that all of you have equal share and the same cannot be denied to the sisters.  If they do not agree, tell them that you will be compelled to approach Courts of law.  You will will 100% hands down.

Remember that daughters are having equal share with sons on self acquired property of father since 1956.

The 2005 issue relates only to ancestral property.

Much depends on acquisition of property by your father and such facts.

lets hope this type of problems do not arise like did one my land, i thought this was a uncurable problem as i found infestation of pests and other kinds of rodents. But the most unusual way yet succesful was the one using ultrasonic rodent repeller.

It is believed that you are all Hindu and Bengali.

In Kolkota (West Bengal) the Dayabhaga school is observed by Bengali Hindu’s.

Confirm.

The father has deceased.

The succession has opened on extinction of father and daughters have equal tight.

Other Perspective:

Ancestral Property; It should be four generation old …………………..in other words property acquired by the Hindu great grand father, which then passes undivided down the next three generations up to the present generation of great grand son/daughter ..

Self acquired property may become ancestral property if it is thrown into the pool of ancestral properties and enjoyed in common..

You have posted that your father bought the property, probably with self-earned/acquired funds.

He was title holder and has expired; hence succession has opened on date of death.

The property has not been partitioned by a registered partition deed.

Your own brothers have adopted a tactical approach to force you, as posted by you to sign relinquishment deed.

You may not sign IT.

Apparently you have equal right and are being pressed to forgo your rights.

You can proceed to protect your rights if your rights are being infringed upon.

Either resolve the matter amicably or if tactical approach to involve some (influential) builder is being adopted to coerce, intimidate, defeat your will and rights and amicable settlement is not possible then you may ASAP approach a very able senior LOCAL counsel of unshakable repute and integrity specializing in such/succession/civil matters and having successful track record ……………and well versed with precedence’s/principles/provisions of personal law that applies in your case ..  and proceed further under expert advice of your counsel….
