What procedure to follow to file case of property with multiple heirs

This is regarding family settlement issue between 2 sons and 4 daughters. While doing family settlement we discussed and everybody accepted the dividing the property. While dividing 2 sons will take the property and for 4 daughters will be settled by cash instead of property. this is deal made. Later we settled the amount to 4 daughters. But now 1 daughter sent the caveat notice to 2 brothers and mother and arguing to divide the property. We paid all the amount her and failed we to get signature in bond/stamp paper. with 1 daughter we completed the registration process. With other 2 daughters we got signature in stamp/bond paper stated that we paid the amount against the property /family settlement. The property is purchased by my mother and she made the registered the property in the name of 2 sons. Now we are very much confused. What we need to do? Wither we can file the case against them or we need to raise any complaint. please advise.
