Εξοικείωση = familiarization (with), familiarity (with), conversance (with) or acquaintance (with)

The main problem in your sentence is that Greek punctuation is different to English punctuation (as I believe I have told you before) and that the English translation of the sentence makes sense if you put a comma after ‘familiarities/familiarisations’, as follows:

“…..to carry out and to sign waivers and familiarities/familiarisations, validations of cheques and drafts”

For a waiver to be valid in insurance the parties have to be ‘familiar with it’. See:

So the first part of your sentence refers to the person carrying out familiarisations with waivers and then signing them.

Frequently, people have to sign a separate part of an insurance agreement or contract confirming that they are familiar with the terms of any waiver or waivers. See:

http://www.amundsen.ulaval.ca/docs/familiarization_guide_ccg...

However, confirmations of familiarity/familiarisation awareness are also required in many other spheres of insurance, so the ‘familiarities or familiarisations’ in your sentence may not apply solely to waivers.
