50% for you and 50% for your dad. After his father died:
50% belongs to you 12.5% belongs to you12.5% Sister A12.5% Sister B12.5% Sister C.
In the end, 62.5% of the property belongs to you and 37.5% to the other three sisters. If you want to get all the properties, you should give 37.5% of the total property price to your sister. If negotiation fails, the local market price shall prevail.
In this case, how to obtain property by the most reasonable means? Because after all, you and your father's contribution is the same, while other sisters don't. There are several ways:
1. If your father isn't dead, transfer the ownership now.
2. As above, you can also choose to notarize a will, but the landlord should consider that it is best to get the approval of all heirs. Think about it. Your father is not dead yet. You want your sister to sign this will. Will they sign it? So I don't think making a will is a good idea.
Ask your father to give you 50% of what he has. However, the real estate gift is not so simple, and the formal basic process is: notarization by the notary office → payment of deed tax by the financial department → tax exemption by the tax department → transfer of ownership by the real estate trading center. The handling fee includes notarization fee, deed tax, transfer fees and registration fee. After all, you still have to go to the real estate trading center to handle the transfer. Instead, let your father transfer the ownership directly.
As for how to deal with it, since you are the party concerned, you should choose a method that you think is appropriate. I hope I can help you.
Supplementary answer, although making a will is a single task, that is to say, only your father needs to make a will himself without anyone's consent, in practice, if you don't negotiate with other heirs, even if you can win the lawsuit, it will often bring long-term negative effects. Therefore, making a will is not a good idea, but. . . Going to the real estate center to transfer ownership has the same effect and may be unpleasant. Let the landlord weigh it himself.
