1) you will have to make application to court for correction of minor errors in the names of the legal heirs
2)There is no doubt that, where the defect is a minor one, for example, in the name of the person whose estate is in question, and the petitioner takes up the correct position by putting in another petition, an order may be made--small error like this may be corrected--Sukumar Deb v. Parbati Bala .
3) passage in Tristraw and Coot's Probate Practice, Edn. 19, p. 327. The passage is this:
"Alteration in a grant has been allowed where the error was in the surname, Christian name, address, status, date of death or place of death of the deceased."
That passage indicates what errors the Court can amend in a succession certificate.
