Procedures to write a will of self earned property?

Is it the self acquired property of your father or an ancestral property? If it is his self acquired property then, he does not require anybody's consent to give it to you. A will should be properly drafted and signed by two witnessess. Care should be taken while drafting the will in respect of certain things particularly if you are sure that the will is going to be challanged by others, so that even if it is challanged you have a strong case. Take the services of a professional lawyer and get it drafted, and register it in the sub-registrar's office [registration is not legally mandatory but is good in many aspects] .

Since the properties are self earned by your father, he can write property in your name... I feel that the objection of your brothers may be that they have to look after you because of your illness... Let the will be drafted well as advised by Adv. Archana
