1) Since D's daughters's consent was not taken though D has executed a partition deed but not a registered one.So I think I cannot use it as my defense and say that D has willingly distributed land to sons.As per 2005 Hindu Succession Act , I think if father creates a registered partition deed or sells his land in his lifetime ,then daughters cant claim it.
Since D purchased the property by a registered sale deed, he becomes the absolute owner of the property.
In the said situation D can transfer/sell/mortgage/gift /settle the property on his name to anyone of his choice and in any manner of his desire.
Nobody can question the authority of D, hence his daughters do not have any right for a share in the property standing on their father's name.
The amendment effected in the year 2005 do not have any impact to this situation.
Options( with respect to case filed by daughters in future)
---
1) Get an registered partition deed of D .What if I do not get it ?
2) Daughters will file case against brother and if they win ..how it is going to affect me as owner of small piece of land.
3) Compensation is a way out but what if they do not agree.
1. The partition deed cannot be executed at this stage especially when the property was already sold by a registered sale deed.
2. The daughter's case is not maintainable, that is the position of law, hence there is no question of winning the case when the re is no provision to file a suit in this regard.
3. Do not offer it, let them approach court with their relief.
There is nothing adverse in this that you are deciding to drop the plan.
Since she do not have any rights in the property, you need not worry about it.
