I am not aware of any specific rules or law being applicable to what you have described as “Lal Dora” area. You may have to consult some local lawyer of your city / state where Lal Dora area lies and who has knowledge of the law related to Lal Dora, if there is any specific law relating to that.
Under the general law, if a Hindu male dies intestate leaving behind his self-acquired property, his property will devolve equally on wife, three sons and a daughter (as mentioned in your question). Wife of such person does not acquire an extra right of ownership in such a case. So, under general law, a transfer deed by the wife of the nature described by you would be invalid.
You can challenge it during the period of limitation.
Transfer of property cannot be made by oral statement. It is required to be in writing and also to be registered.
