Shal i go for sell deed with other three members on the second part of property and wait for permission for the minors.
It is not legally valid, you cannot do that.
Go for registerd sale agreement or notary agreement for sale with all the members on the second part including minors. And wait for the permission.
Minors cannot enter into sale agreement for any reason till they become major by age.
Notarised sale agreement is not enforceable in law nor it is admissible as evidence in court.
In my case diseased father already recieved money and had a agreement to sale with my friend before his death.
Even then his legal heirs have to execute sale deed on behalf of the deceased, hence there is no escape from this in law.
