true. Someone should report an inventory of the property of the decedent within three months to the court. The court shall give public notice according to the procedure of public summons, calling upon the creditors of the decedent to present their claims within a specified period of time.
If the will is binding, you should follow it, but can claim for compulsory portions.
If the will is not binding, you can divide the asset in anyways as far as heirs all agree to the way. You should submit the agreement paper to the court.
I also think your wife need a lawyer.
