Hi Maria,

Regarding your question; it's not too hard and complicated as it seems to have a legitamate document of this kind which is called the Probate Verdict in Turkish Law.

But to get it there is an another document which expilicitly certifies the deceased person's all living/passed relatives for that moment to be obtained via lodging to Turkish Parish Register.

After having the forementioned document; you've got to lodge to the Magistrates Court
( preferably to the one where the deceased used to dwell ) to have a Probate Verdict ( it is not and differs than the Probate Action ) appertaining to the deceased but of course together with a written petition stating your claim.
But please note that this has to be done properly as soon as possible to avoid time bar and can only be done by your solicitor who is registered to Turkish Bar Association and for sure with a power of attorney given by you or your client.

Best Regards,
