- Being the self acquired property , your grandfather was having right to transfer his property to anyone , hence the WILL registered by your father is legal. 

- Since, the said property is still in the name of grandfather, hence for getting the share of your father , the said WILL should be probated.

- File a Probate petition before the court. 

Collect death certificate of the testator and make  declaration of all heirs beneficiaries of the will. Get an authenticated copy of the will and submit all the documents in municipality for mutation in the name of all beneficiaries. 

Note that though probate of will is not mandatory but it considered safe from future dispute by any legal heirs if the probate of the will is obtained from court. 

1. Whop was the executor of the said will?

2. Has probate of the said will been applied for and availed?

3. Without the grant of probate, will has no value better than a scrap paper.

4. Application for probate shall have to be filed before the Court to enable you to claim your father's share of the willed property of your grandfather.

1. While applying for mutation of the said property, the KMC authority will ask for the legal heir certificate which will include all the legal heirs of your deceased grandfather or the probated will.

Get an application filed by any of the living beneficiaries of the said will  to get probate for the same.

1. First take probate of the Will .

2. once Probate is granted then on its basis apply for mutation of the property in your respective names as per direction of the Will.

3. If the property falls within the area of KMC then it is has to be applied in KMC only.

As per the Will made by your grandfather has distributed his property to four of his children out of his six children.

Thus the property can be divided into four shares  by a registered partition deed among the four beneficiaries 

After the partition deed, each beneficiary can mutate the properties on their individual names  after which they will become the absolute owners of the share of  property allotted to each of them.

Your paternal uncles even though they do not have children, they are entitled to acquire their own share as per the bequest made in the Will by their deceased father.

Nobody can claim a share in that property as a right at least not during their lifetime.

You, your mother and your siblings can inherit your father's share in the property that too only after his lifetime and not before that.

Your father and his siblings can do mutation of the property on their respective names after getting the property partitioned and reduced the same to writing and by getting it registered  

There is no useful purpose solved by getting it mutated on joint names.

So far the advises and opinions rendered were legal and professional only.

What is your doubt about it.

You need you do the Mutation and transfer at KMC. 

You need to apply to get the Will probated.

Once the Will is probated, it can be used in any proceedings as authentic proof.

Upon completion of the said proceedings, you can get the name mutated in the revenue records by submitting the original Will, death certificate, no objection of other heirs.

You need to contact local lawyer for completing the procedural part.

1. The property devolved according to the will of your grandfather.

2. If your two uncles died issueless then their share devolved further on their (1) Brother’s son, (2) sister’s son, (3) brother’s daughter, (4) sister’s daughter who are Class 2 heirs. All the heirs spelled out in Class 2 succeed equally.

3. The division can take place amicably by executing a registered partition deed and thereafter mutation can be done.

Uncles are alive or not ? If not than their share will inherit to their living brother/sisters. IF your father is alive than he will inherit 1/5th share otherwise only sisters by 1/4th share each. Children of deceased brother have not inheritance right.
