Marriage to Hungarian citizen

My name is Joseph. I have relocated here to Budapest, Hungary, to be with my fiancee. We would like to be married as soon as possible. Has anyone had experience with this process? I will take pertinent documents to a Hungarian Authority for a certified translation from English to Hungarian and I am concerned that perhaps the translation they give will not be correct and that in turn, this will cause more delay in the whole process...not to mention more money as well. Additionally, I need to apply for a residence card once married, and I will definitely need an extension of time to stay here in Hungary in order to have sufficient time to close these matters successfully. Any advice or experience regarding these matters is greatly appreciated. Thank you for your time

~Joseph
