Inheritance value question

Hello all,

I live abroad all my life and my Lithuanian grandfather passed away recently and I got a notice from notary about the certificate of inheritance. I have no idea what that person was having as a possession ( money,property etc etc). Is it possible to calculate roughly how much the whole value is based on the invoice from the notary ? I upload a picture down below. It would help me a lot because I really dont plan to pay more than id receive as i have no idea what is the value and there are 4 in total heirs including me.

Thank you!

Edit : i just want to make sure that if I pay 100€ for an example, that id receive more than those 100€ that I paid. Im worried if all this circus would be for 10€ split among 4. As i dont know and never heard that that person owned something
