How can wife and daughter get the share in property of husband

In the event - when wife is unsure that husband will name the property to family members, how can wife legally make assurance that the property should only be passed to wife and daughters. Does the gift deed works OR objection letter should be prepared against the property division OR what are the steps to be taken. Please advise NTD: This is only to make sure things falls to family members and wife is justified for her efforts in creating property and nothing to do with violence. The property is taken on loan & originals are under bank custody. Loan will be completed shortly.
