Sir firstly the succession certificate is movable assets that is debt and security or money. Further if appeal is rejected in district court file before the high court. Further I would advices you to meet some local advocate with documents as to check possibility partition suit in same is possible or not.

1. Succession certificate relates to movable assets only and not for immovable property like house.

2. However since your grand father has died intestate both your father and your aunt have inherited his property including the house in equal share.

3 Now if your aunt is not giving the due share of your father he can file a suit for partition in the local court. 

4. The appeal you have mentioned is not clear to me as with what regards it was preferred. In any event filing of partition suit is only option. 

You should have acted earlier, challenging your aunt's application for Succession Certificate. Now nothing can be done. So don't waste your resources in pursuing this matter. 

1) In Succession certificate does you father's name has been mentioned in it or not ?

2) If your father's name has been mentioned on it and on property papers than you father can get 50% share in the house property.

3) Kindly check current mutation papers of house on whose name the title of house is.

You need to challenge the order of the Appellate Court before the High Court.

She having already obtained the succession certificate fraudulently, the only course open to you is to assail the same.

It is a legal principle that fraud vitiates everything, even the most solemn acts; relying on this principle go ahead and contest the case.  

1) delay of 17 years in filing appeal went against you 

2) hence court passe corder that claim is barred by limitation 

3) it should be your case that succession certificate was issued fraudulently and you were not informed nor issued notice about filing of said SC 

Dear Sir,

You have to again prefer appeal before High Court and see that order passed by District Court for set aside.  The cause of action is the date of knowledge when your father came to know about such misleading order.  Actually it was a fraud played on the court as such there is no limitation to lodge complaint and get register a criminal case also.

Limitation act comes into picture as and when other share holder demands their share. Your case that is 2016 only.you can give even criminal case against her to hide your father as one of the legal heir and got the succession certificate.

There is no limitation for the partition of the joint property. 

Dear client, 

Order is obtained by fraud , your mother has no right to relinquish father share. Issue not barred by limitation. What order says ?   and succession certificate dose not issue for immovable property .

1. You can Try filing a WP in the High Court, to set aside the Succession Certificate, citing that it was obtained by Fraud and Misrepresentation, since Grand Father had not executed any WILL for his property.

2. Also file new Civil Suit, to claim Share in the Grand Fathers property, citing absence of Grand Fathers WILL. Also file Delay Condonation Application for the delay, giving strong reasons. It would be worth a try.

Your father can file a partition suit seeking partition and separate possession of his legitimate share in the properties left behind by his father who is reported to have died intestate.

Partition has no limitation.

You can challenge the said succession certificate as it is taken by fraud with giving notice to all legal heirs.

1. Succession Certificate in the first place is issued only for realisation of liquid assets, not immovable assets.

2. Be that as it may, get the succession certificate vetted by a lawyer and then apply for setting it aside if it has been obtained fraudulently. Your father should file a suit for declaration of being a legal heir to his father and also seek partition of the property. 

3. Unless all case related documents are perused threadbare no opinion can be formulated.
