Dear Friend,
There is no need for sample formats to fill out Form 10C and 19 as they are easy to fill out. You can easily fill out both forms yourself. You need to provide your Name, Father's Name, Date of Birth, Date of Joining, Date of Leaving, Address, Bank Details, etc. Additionally, you need to affix two 1 Rupee Revenue stamps in the appropriate places and sign in the respective spaces.
In Form No. 10C, there is a question asking if you are willing to accept the scheme certificate. Here, you have to tick 'No', otherwise, they will issue a certificate that needs to be retained until you reach the age of 58.
If you read both forms carefully, I am sure you can easily complete them. After filling out these forms, forward them to your ex-employer. Once they have completed their formalities, such as signing and filling out Form 3A, you can submit the forms to the P.F. office.
Wishing you all the best.
